CONSULTATION PAPER ON FREQUENCY LAYOUT PLAN OF IN-BUILDING COAXIAL CABLE DISTRIBUTION SYSTEMS Issued by the Office of the Telecommunications Authority 31 March 1999 INTRODUCTION As a result of the 1998 Review of Television Policy, the Secretary for Information Technology and Broadcasting announced Government's decision in December 1998 further open up the television broadcasting market in Hong Kong. The review has also identified that one of the hurdles in further opening up of the market is the limited capacity of the in-building distribution systems in highrise residential buildings. To address this problem, the Government underok formulate an optimal frequency layout plan and draw up technical specifications on the standards of distribution for consultation with the industry. Having conducted an internal study on a frequency rationalization plan for in-building cable distribution systems and the technical standards for the distribution system and associated set-p boxes, this consultation paper seeks views and comments from the industry before the Telecommunications Authority (TA) finalizes these technical standards facilitate the introduction of new television services.

2. The TA welcomes views and comments on any issues raised in this Consultation Paper and in particular the points listed in paragraph 58 below. All views and comments should be sent the Office of the Telecommunications Authority by 30 April 1999 via: Post: Office of the Telecommunications Authority Wu Chung House, 213 Queen! s Road East, Wan Chai, Hong Kong. (Attn: Mr Y. C. Leung, Senior Telecommunications Engineer) Fax: (852)29047141 E-mail: ycleung@ofta.gov.hk 3. The TA reserves the right make public all, or parts, of any submissions made in response this Consultation Paper. CURRENT SITUATION 4. At present, Television Broadcasts Limited (TVB) and Asia Television Limited (ATV) provide four terrestrial television programme channels. Hong Kong Cable Television Limited (HKCTV) uses 36 frequency channels for providing cable television (CTV) services, five of which are assigned for temporary use until 24 April 1999. Hong Kong Telecom VOD Limited (HKTVOD) provides video-on-demand (VOD)

programme services through the Fixed Telecommunications Network operated by Hong Kong Telecommunications Limited. There are also a number of free satellite television signals which are relayed the viewers by Satellite Master Antenna Television (SMATV) systems. In addition, there are security video signals conveyed the viewers through closed circuit television (CCTV) systems. Except for the VOD service which is distributed by twisted copper wires, all other television services and signals are distributed by coaxial cable systems in residential premises. These may include communal aerial broadcast distribution (CABD) systems, SMATV systems, CCTV systems, CTV system or any combination of these systems. Such coaxial cable systems are commonly referred as "In-building Coaxial Cable Distribution System (IBCCDS)". A typical configuration of an IBCCDS is given in Annex 1. Communal Aerial Broadcast Distribution (CABD) System 5. At present, the four terrestrial television channels are transmitted in the frequency band of 470-790 MHz. To avoid signal interference, different terrestrial television transposers use different groups of transmitting frequencies. The frequencies employed for transmitting the four terrestrial channels are detailed in Annex 2. Within a CABD system, it is common distribute terrestrial television programmes at the same frequencies as they are received off-air. However, if the CABD system operates in close proximity a transposer, off-air signal levels will be high (say, over 90 db LLV/m) and interference may be experienced due direct pick-up of this strong off-air signal by the CABD system and

receivers. Under this condition, the reception frequencies are normally translated different distribution frequencies avoid interference. Therefore at present a common terriry-wide frequency plan for distribution of terrestrial television programmes in the CABD does not exist. Under section 8(4)(e) of the Telecommunication Ordinance (Chapter 106), CABD systems are exempt from licensing. As there is no statury requirement for CABD operars report information about the CABD systems the TA, the TA does not have a central record of the frequency channels used by the CABD systems. It is estimated that there are about 5,000 CABD systems in Hong Kong. Closed Circuit Television (CCTV) System 6. CCTV system is used for internal information and security communication purposes. Usually, a CCTV system is combined with the CABD system in the same building and occupies one channel within the frequency range of 470-750 MHz. Under section 8(4)(f) of the Telecommunication Ordinance (Chapter 106), CCTV systems are exempt from licensing. Again there is no central record of the frequency channels that are used by CCTV systems. It is estimated that there are over 5,000 CCTV systems in Hong Kong.

Satellite Master Antenna Television (SMATV) System 7. SMATV systems are subject licensing under the Telecommunication Ordinance (Chapter 106). Most SMATV systems distribute 4-5 satellite television channels but some may distribute more than 15 channels. Some statistics of the number of satellite television channels carried by SMATV systems are provided at Annex 3. The distribution frequencies of SMATV systems are within 470-750 MHz. SMATV operars are required submit frequency transmission plans of their SMATV systems the TA for approval. Usually, a SMATV system is combined with the CABD system and the CCTV system in the same building for distribution of satellite television, terrestrial television and CCTV signals. The formats of satellite television signals may be PAL or NTSC which occupy a bandwidth of 8 MHz and 6 MHz respectively. In the IBCCDS, both 8 MHz channel plan and mixed 8 MHz and 6 MHz channel plan are used distribute the signals. For SMATV systems which carry only a few free satellite television programmes, alternate channels in the 470-750 MHz band are used avoid adjacent channel interference. For SMATV systems which carry a large number of satellite television programmes, sharp filters are installed so that adjacent channels can be used. As at February 1999, there were 1,644 SMATV systems connecting 548,557 households in Hong Kong.

Cable Television (CTV) System 8. At present, there is only one cable TV operar in Hong Kong, namely Hong Kong Cable Television Limited (HKCTV) (formerly known as Wharf Cable Limited). HKCTV has built a hybrid fibre-coaxial cable (HFC) network and a microwave multi-point distribution system (MMDS). Both networks use coaxial cable for in-building distribution. The operating frequency range of the coaxial cable is up 750 MHz. Currently HKCTV uses 36 frequency channels, five of which are assigned for temporary use until 24 April 1999, over the HFC network and 20 frequency channels over the MMDS-coaxial cable network. Subscribers connected the HFC network can receive up 36 channels ( 5 channels are temporary) whereas those connected the MMDS can receive only 20 channels. The MMDS frequencies currently assigned HKCTV are for temporary use only and they have be surrendered by 31 May 2001. As at the end of January 1999, HKCTV's HFC network and MMDS passed about 640,000 and 968,000 homes respectively. The frequency ranges of the upstream data channel, downstream data channel and programme channels of the CTV system are in the frequency bands 8.3-10.4 MHz, 53.275-53.425 MHz and 54-462 MHz respectively. Under section 18(4)(aa) of the Television Ordinance (Chapter 52), the transmission plan of CTV system is subject TA's approval. 9. CTV system is usually interconnected with the SMATV/CABD systems in the same building enable the subscribers receive CTV, SMATV, terrestrial television and CCTV signals via the existing single drop cable. The channel numbers 1? 2, 3 and 4 as

displayed on the CTV set-p boxes are reserved for the four terrestrial television channels while the channel numbers 5-24 and 76-95 are assigned CTV channels. Cable Telephony 10. The frequency ranges of 21-25 MHz and 462-466 MHz have been assigned New T & T Hong Kong Limited (New T&T) for the upstream and downstream signals respectively for its telephony service. RF Outputs of VCRs and Set-Top Boxes 11. Currently, three channels in 766-790 MHz are assigned for the radio frequency (RF) outputs of CTV set-p boxes. Only one channel is required and most CTV set-p boxes are set channel E 59 (774-782 MHz) with the remaining set channel E 58 (766-774 MHz) or channel E 60 (782-790 MHz). Two channels in 470-750 MHz are assigned for RF outputs of video cassette recorders (VCRs) and set-p boxes for VOD service. The preset RF output channels of VCRs are usually in E 35 (582-590 MHz) E 38 (606-614 MHz). The RF output channel of set-p boxes for VOD service is not fixed.

Prohibited Frequency Ranges 12. There are 10 frequency channels (Annex 4A) in the 54-470 MHz band which overlap with some essential services (e.g. aeronautical radio-navigation for air traffic control, emergency position indicating radio beacon for search and rescue purpose in case of distress). The use of these 10 frequency channels will generate unacceptable interference which may affect the normal operation of the essential services and therefore are prohibited for use. Existing Frequency Allocation Plan and Spare Channels 13. The existing frequency allocation plan for IBCCDSs is given in Annexes 4 A and 4B. Some typical examples of the frequency plans used in SMATV/CABD systems operating in 470-750 MHz are given in Annexes 5 A, SB and 5C. Most systems employ a channel width of 8 MHz. However, some SMATV systems (about 150 systems) employ a mixture of 6 MHz and 8 MHz channel widths for distribution of satellite television programmes. This is because certain satellite television programmes which are broadcast in 6 MHz channels are relayed directly the distribution network without any conversion. An example of these systems is given in Annex 6. 14. To avoid adjacent channel interference, most of the IBCCDSs adopt an alternate channel plan in the UHF band. Only a few SMATV systems use an adjacent channel plan and have installed filters at the 8

headend reduce the interference. In the VHF band, the main user is HKCTV and it uses adjacent channel plan with filters at the headend as well as the receiving end (Set-p Box). Spare Channels in the VHF (54-470 MHz) Band 15. There are 52 channels with 8MHz bandwidth available in the VHF band. 31 channels have been allocated HKCTV with another 5 channels for temporary use. 10 channels are reserved protect essential services (Annex 4A). One channel has been assigned for telecommunications services and a block of 4 MHz of the channel has been allocated New T&T for telephone services. There are only 5 channels left. Two of the 5 channels (166-174MHz and 278-286MHz) fall in the paging services frequency blocks. Interference is high and these two channels are therefore not usable for other purposes. One of the 5 channel (78-86MHz) suffers strong signals from mobile radio systems and is also not usable. The number of channels available in the VHF band meet new demand is therefore 7 (5 temporary channels and 2 spare channels). Spare Channels in the UHF (470-790 MHz or 862 MHz) Band 16. There are 35 and 49 channels of 8 MHz bandwidth in the 470-750MHz and 470-862MHz bands respectively. In general 4 channels are required for terrestrial television services, one channel for CCTV, one channel for radio frequency (RF) output of VCR, one channel for RF

output of set-p box of HKCTV and about 10 channels (95.75% of the SMATV systems install 10 channels or less) for SMATV services. If adjacent channels are not used, there is only one spare channel available in 470-750 MHz systems and a maximum of only 7 spare channels in 470-862 MHz systems. If adjacent channels are used, a maximum of 19 and 32 spare channels are available in 470-750 MHz systems and 470-862 MHz systems respectively. NEW SERVICES 17. On completion of the 1998 Television Policy Review, the Government has announced its policy decision, inter alia, open up the television market for free competition. Companies which are interested in establishing new television services, whether on a free or subscription basis, can apply for relevant licences under the liberalized regulary regime subject the physical constraints of available spectrum. Broadcasting-Satellite Services (BSS) 18. In November 1997, the International Telecommunication Union (ITU) allocated Hong Kong 4 Ku-band channels for the provision of BSS. Preparary work for the licensing of BSS is underway and the Government intends invite applications for the use of these four channels in late 1999. 10

Digital Terrestrial Television (DTT) 19. The technical trials on DTT will be conducted with the two terrestrial television broadcasters in 1999. On successful completion of the trials, simulcast of analogue and digital terrestrial television could commence in 2001. Telecommunications Services 20. In an emerging multi-media and technologically convergent environment, there will be increasing demand for delivering telecommunications services such as fast Internet and cable modem services consumers through IBCCDSs. PROBLEMS 21. There is a growing demand for frequency spectrum in IBCCDS meet the need of conveying new television and telecommunications services as mentioned above as well as the increasing number of channels of the existing CTV service and SMATV service. 22. However, the frequency channel capacity inside the IBCCDS is limited. The last horizontal drop cable which is the only coaxial cable access point individual residential premises will remain a bottleneck for the introduction of new services. The installation of a second horizontal 11

drop cable is difficult in practice in most existing buildings in Hong Kong. The TA considers that the frequency spectrum within IBCCDS is a limited resource and is a public property. There is therefore a need properly regulate and allocate the frequency channels in IBCCDS enable maximum efficiency in the use of these systems. 23. Although vacant channels are currently available in the existing IBCCDS, the number and frequency ranges of these channels vary for different IBCCDS as these depend on the reception frequencies of terrestrial television channels as well as the distribution frequencies of satellite television programmes and CCTV signals. Service providers will find it difficult plan their new services if there is no central record of the frequency channels used in the IBCCDS in Hong Kong. PROPOSALS 24. If there is no requirement for new television services in an existing building, congestion in the IBCCDS will not happen. Therefore it is proposed that the following requirements need not apply those buildings where the residents do not wish have new television services be carried in their IBCCDSs. However residents wishing increase the capacity or use the spare capacity of their IBCCDS receive the new television or telecommunications services should follow the arrangements as described in the following paragraphs: - 12

Channel Plan 25. To facilitate the allocation of frequency spectrum in the IBCCDSs, it is proposed that a channel plan specifying the channel numbers and the frequency ranges of each channel should be formulated. The following approach is recommended. (a) VHF (54-470 MHz) The current channel numbering and frequency ranges as given in Annex 4A are compatible with the design of set-p boxes. It is proposed that no change should be made. The proposed channel plan for the VHF band is given in Annex 7A. It is also proposed that the 7 spare channels mentioned in paragraph 15 should be made available for allocation by the TA services employing digital or other advanced spectrum efficient technology. (b) UHF T470-862 MHz) There are two options for the channel plans for the UHF spectrum. Option 1 is designate a fixed bandwidth of 8 MHz all the channels. The lower and upper frequency ranges of each channel will then be fixed. Existing signals distributed in the 6 MHz NTSC format will be required stay within the 8 MHz slot and their vision carriers will be aligned with those of the 8 MHz plan. This option enables the use of a common channel plan for all IBCCDSs in Hong Kong. The harmonics generated will also spread evenly over the 13

UHF band. However, some of the SMATV systems now using a mixture of 6 MHz and 8 MHz channel plans may be required rearrange their channels. The cost involved should be under HK$ 10,000 per channel per system. Option 2 is allow the co-existence of a mixture of 6 MHz and 8 MHz channel widths. This means existing SMATV systems using a mixture of 6 MHz and 8 MHz channel widths will not be required rearrange their channels. However, a main drawback of this option is that common channel plan for all IBCCDSs is not possible and the harmonics will fall unevenly across the UHF band causing interference. The consequence is fewer channels will eventually be available. Therefore it is proposed that Option 1 should be adopted. The proposed channel plan is set out in Annex 7B. Similarly, it is proposed that the spare channels should be allocated by the TA licensed service providers employing spectrum efficient technologies. Digital Environment 26. The above channel plan employing a bandwidth of 8MHz is compatible with the digital channeling requirements. Each 8MHz block will be further sub-divided in 6 or more digital channels depending on usage and compression ratio. Digital channels will be allocated licensed service operars in whole or part of the 8MHz block. This plan 14

may be reviewed as necessary, particularly when digital terrestrial television has been introduced. Fixed Channel Plan Employing Adjacent Channels 27. In order facilitate the easy planning of introducing new services, it will be useful if the same frequency channel is used in each IBCCDS distribute the same television programme in the whole terriry (i.e. a frequency channel is used distribute a particular television programme in individual IBCCDS). Two options exist achieve this. Option 1 is use Channels E21, E23, E25 and E27 for TVB and ATV (Annex 12C). This avoids excessive translation of frequencies; but for those buildings served by Temple Hill transmitter with strong off-air signals, alternative channels will be required. Option 2 is translate all existing off-air channels a uniform pattern, for example E31, E32, E33 and E34 (Annex 12D). The exact channel plan will be specified by the TA having consulted the industry. In addition, in order have the maximum numbers of channels available in an IBCCDS, it is proposed that all the adjacent channels should be used. IBCCDS not conforming this plan will have be modified. Some old television receivers may suffer from adjacent channel interference. Set-p should be employed overcome this problem. 15

Channel Numbers as Displayed on Set-Top Boxes 28. In most set-p boxes it is possible set a channel number a programme service which is independent of the frequency channel the service is being transmitted on. It would be more user friendly if the channel numbers as displayed on set-p boxes could also be made uniform everywhere in Hong Kong. Accordingly, views and comments are sought on whether this is necessary. Viewers normally set their terrestrial television channels channels 1 4 on their television sets. To make it easier for the viewers, it is also proposed that the present arrangement of reserving channel numbers 1 4 on set-p boxes for the terrestrial television channels should continue. Proposed Principles for Frequency Allocation 29. In order achieve efficient use of frequency spectrum, digital technique and other advanced technologies which can increase the channel capacity of the IBCCDS must be adopted for any new services. Priority 30. Given the congestion in the drop cable it is proposed that the frequency spectrum in the IBCCDS should be assigned according a priority system, as proposed below:- 16

(a) Safeguarding existing services All existing services shall be safeguarded and shall continue be distributed by IBCCDS. (b) Domestic Services over non-domestic Services Domestic Services not only provide entertainment, they also offer means of communicating essential public information such as typhoons and rainsrms. (c) Terriry-Wide Services over Localized Services Terriry-wide services which serve the wider community and a greater number of viewers should have priority over localized services. Fair Competition 31. To ensure fair competition, a minimum set of channels should be allocated each licensed service operar as far as practicable. Additional channels will be allocated on the basis of proven demand. 17

Proposed Priorities for Distribution in IBCCDS 32. In accordance with the principles set out in paragraph 30, it is proposed that the following arrangements should be adopted: - (a) all existing services including the four terrestrial channels, 31 CTV channels, one CCTV channel, one VCR RF output channel, one VOD RF output channel, one set-p box RF output channel should continue be distributed; (b) all licensed satellite television channels which are already in service (at present four channels of STAR TV) should continue be distributed; (c) up 10 channels in the 470-862 MHz band should be reserved for services as decided by the residents of a building, such as for distributing free television programmes of their choice including terrestrial and satellite services, or other localized services; and (d) the rest of the spare channels mentioned in paragraphs 15 and 16 be allocated licensed services employing digital or other spectrally efficient technology. 18

Database for In-Building Coaxial Cable Distribution Systems 33. It is proposed that all licensed service operars should submit the channel plans of their IBCCDSs for TA T s approval Service operars should also seek the TA's approval for any subsequent changes their channel plans. With the availability of this information, OFTA will be able compile a database for all IBCCDSs. It is proposed that this database should be published for public access in order facilitate system planning by service providers. An example of the data be published is given in Annex 8. The TA will also encourage the owners of the CABD and CCTV systems provide OFTA with their channel plans and any subsequent changes. To Increase Channel Capacity 34. There are several methods increase the channel capacity of IBCCDSs. These are explained in the following paragraphs:- Frequencies Prohibited for Use 35. As explained in paragraph 12 above there are 10 channels falling in the frequency blocks which are prohibited for use. OFTA will carry out further studies find out whether some of these restrictions may be relaxed. 19

Digital Compression Technology 36. By employing digital compression technology, one analogue television channel can be used deliver several digital television programme services. The technology is already available in the market. To promote the efficient use of the limited frequency spectrum, it is proposed that service operars should be required adopt this technology for introducing any new services. It is also proposed that a compression ratio of 6 or more should be employed. Extend the Upper Operating Frequency 37. Most of the existing IBCCDSs are designed operate up 750 MHz. Accordingly, the maximum number of 8 MHz channels available in 54-750 MHz is limited 87. By extending the upper operating frequency of the systems 862 MHz or 1 GHz, the numbers of channels of the IBCCDSs could be increased 101 and 118 respectively. The following considerations should be taken in account in deciding whether IBCCDSs should be upgraded 862 MHz or 1 GHz: - (a) avoid interference the aeronautical radio-navigation service operating in 960-1215 MHz, the upper operating frequency should not exceed 960 MHz; (b) there are 26 channels in 750-960 MHz of which 11 channels overlap with the transmitting frequency ranges of the base 20

stations of the Trunked Mobile Radio System, Public Paging Services and Public Mobile Radiotelephone Service (Annex 9). These 11 channels might suffer interference, especially when the IBCCDSs are close the base transmitter stations. Better shielding is required for these systems. Similarly there are 14 channels in 750-862 MHz where 2 channels overlap with other licensed transmitting frequencies. Again extra shielding will be required if these 2 channels are be used; (c) set-p boxes are required receive the channels in 862-960 MHz as most television sets are equipped with tuners operating up 862 MHz only; and (d) for a typical 30-metre drop cable, the cable losses at 600 MHz, 800 MHz and 1 GHz are about 4.6 db, 5.4 db and 6.0 db respectively. The cable loss at 1 GHz is not significantly greater than that at 600 MHz and such loss should not significantly degrade the quality of signals. However, very old drop cables may cause high attenuation signals above 750 MHz and the quality of signals may be significantly degraded. These drop cables may need be replaced if the IBCCDSs are upgraded operate beyond 750 MHz. 38. In the light of the foregoing considerations, it is considered that there is not a lot of benefits be gained by upgrading IBCCDSs 1 GHz. On the other hand, upgrading 862 MHz is possible and relatively 21

easy implement. an upper limit at 862 MHz for the time being. The proposed central allocation plan therefore has 39. Licensed operars willing upgrade the IBCCDSs operate beyond 862 MHz are encouraged do so. The additional frequency channels above 862MHz will be allocated by the TA only licensed services employing digital or spectrally efficient technology. Intermediate Frequency (IF} Distribution Method for Satellite Signals 40. In existing SMATV systems, satellite signals are normally demodulated the base band at the roofps and then re-modulated again for distribution in 470-750 MHz. Television sets tune in the satellite signals in the same way as they tune in terrestrial television signals. In an IF distribution system, satellite signals are translated intermediate frequency in 950-2150 MHz with a typical bandwidth of 40 MHz. These signals are then distributed by the IBCCDS outlet points. Each user has install an integrated receiver decoder (IRD) (or commonly known as satellite receiver) in their premises receive the satellite television signals. The output signals of the IRD can be connected the video or RF input of a television receiver. IF distribution method has been used elsewhere for several years and comprehensive products for IF distribution are available in the market, though they are mostly designed for small distribution systems covering short distance. More sophisticated design with good installation and maintenance are required for large scale distribution 22

systems. 41. Additional expenditure will be required for this option. For example, the cost of installing a new IF distribution system (excluding the satellite dish and receiving equipment) for a building with 30 sreys with 8 flats per srey is about HK$ 100,000. The cost per flat is about HK$420. In addition, each subscriber will need an IRD which costs around HK$2,000 plus depending on functionality and features. 42. If IF distribution method is used, there is a need prevent interference caused essential services. The concerned frequency ranges of 960-1215 MHz (aeronautical radio-navigation), 1300-1350 MHz (aeronautical radio-navigation) and 1400-1427 MHz (earth exploration-satellite, radio astronomy and space research) which overlap with the intermediate frequency range need be protected. In addition, the frequency range of 1452-1492 MHz should be reserved for distributing digital audio broadcast signals. The remaining spectrum in the range of 1215-2150 MHz can provide about 20 channels with 40 MHz channel bandwidth. With digital transmission, more than 100 channels of standard television quality could be distributed. This will greatly increase the available channels for new services. 43. Service providers or SMATV operars willing install IF distribution systems are encouraged do so. They should bear all the cost for upgrading the cable distribution network and the following conditions should apply: - 23

(a) the IF distribution method should be used for distributing satellite television or radio signals only; (b) the use of IF distribution method should not affect the transmission and access of signals below 862 MHz including the upstream signals; and (c) the satellite receiver for decoding the television signals should satisfy the requirements as stated in paragraphs 52 56. Parallel Distribution Network 44. The capacity of an IBCCDS can be increased by installing multiple vertical coaxial cables in parallel with existing ones. A remote controlled switch will be required enable individual user select which vertical cable the final drop cable is connected. A typical configuration of a parallel distribution network (PDN) is shown in Annex 10. This is a complicated option and the following constraints exist: - (a) there are practical and technical constraints, such as space for the installation of remote controlled switch, power supply for the switch, distribution amplifiers, ownership, maintenance responsibility, which have be overcome ; (b) there are limited equipment suppliers for the remote 24

controlled switches and consumers need install individual remote controllers; (c) the switches available in the market are normally directional and do not support upstream signaling; (d) simultaneous reception and recording of services distributed by different vertical cables are not possible; and (e) the cost of installation is quite high. A typical installation for a 30-srey building with 8 flats per srey costs HK$240,000. Cost per flat will be around HK$ 1,000. 45. Despite the above constraints, licensed operars willing adopt this method increase channel capacity should be encouraged do so. This method can also be adopted if some residents of a building wish receive new services while others wish remain on the old system only. The following conditions should apply: - (a) after the installation of a new parallel distribution cable network a viewer should still have access all the television signals of the original network; (b) some basic channels, such as the four existing terrestrial television channels and possibly other future channels designated as basic channels by the Government, must be 25

carried in all the vertical cable networks enable recording and separate viewing of these channels ; and (c) operars should provide a technical means ensure that all types of upstream signals will not be affected regardless of which vertical cable network a viewer selects. Frequency Spectrum for Upstream Signals 46. At present, a tal bandwidth of 6.1 MHz in 5-50 MHz is used by cable television and cable telephony services (Annex 4AV It is proposed that the whole frequency spectrum in this band i.e. 5-50 MHz should be allocated by the TA for upstream signals of pay television and telecommunications services on a need basis. A licensed operar will be allocated a minimum but sufficient block of spectrum meet the need of the service initially. Additional allocation the operar will be made based on proven demand. Frequency Spectrum for Downstream Signals of Telecommunications Services 47. In addition the possible allocation of some of the 8MHz channels for telecommunication services, fully utilize the frequency spectrum of the IBCCDSs, it is proposed that some of the vacant frequency 26

bands with bandwidths less than 8 MHz in 54-470 MHz should be allocated for downstream signals of telecommunications services as shown in Annex 11. A licensed operar will be allocated a minimum but sufficient block of spectrum meet the need of the service initially. Additional allocation the operar will be made based on proven demand. Proposed Frequency Allocation Plan 48. As described in paragraph 27, the proposed fixed channel plan with the use of adjacent channels for television programmes and telecommunications services be distributed in the IBCCDSs is specified in Annexes 12A, 12B«12C and 12D. In order leave more channels for carriage of telecommunications services and television programmes., it is proposed that the current plan (see paragraph 11) of using 3 channels for RF outputs of set-p boxes should remain unchanged. 49. In order minimize uneven harmonic signals caused by the distribution of mixed 6 MHz and 8 MHz television signals in the IBCCDSs, it is proposed that the vision carrier frequencies of all 6 MHz television signals should be aligned with those of the 8 MHz channel plan. 27

SUMMARY OF PROPOSALS FOR IBCCDSs 50. The following is a summary of the proposals: (a) (b) (c) (d) (e) (f) (g) adopt a 8MHz channel plan with the use of all the adjacent channels (Annex 7); adopt a fixed channel plan as specified by the TA for distributing different television programmes and telecommunications services ( Annexes 12A. 12B. 12C and 12D); a compression ratio of 6 or more should be used in digital transmission; 862 MHz be adopted as the minimum upper operating frequency of IBCCDS for new systems or systems be upgraded; the use of all the channels of an IBCCDS for new services is be specified by the TA; subject the requirements set out in paragraph 43, IF distribution may be used for carrying satellite television programmes; and subject the requirements set out in paragraph 45, parallel distribution cable network may be used. IMPLEMENTATION 51. The following implementation approach is proposed:- 28

(a) For buildings where the residents do not wish have new television programmes or telecommunications services be distributed by the IBCCDS, the IBCCDS may remain unchanged and upgrading work is unnecessary. (b) For buildings where owners want receive new television programmes by using the IBCCDS, upgrading would only be necessary when the capacity of the IBCCDS is full. This avoids excessive expenditure at the initial stage. However, when upgrading of the IBCCDS is necessary, the requirements set out in paragraph 50 should be followed. Alternatively, a new vertical cable may be installed carry the new services serve those owners who wish have new services and the conditions set out in paragraph 45 apply. As regards the cost for the upgrading work, subject commercial agreement, it may be paid wholly by or shared among the Owners Incorporations, the licensed television service providers, the licensed telecommunications service providers and the parties concerned who wish distribute the services the building. BASIC REQUIREMENTS FOR SET-TOP BOXES 52. The TA considers that it would be desirable have a universal standard for set p boxes so that a single set-p box could be used distribute all the television and telecommunications services. 29

However, reasons : - this is not entirely possible at this stage for the following (a) (b) (c) the digital transmission and compression ratios used by different operars may be different; the service offerings of each operar may not be the same; and the conditional access systems used by each operar may be different. 53. Despite the above constraints, the TA considers that it is desirable introduce the following basic requirements on set-p boxes ensure fair competition and free access of services as well as facilitate interconnection of set-p boxes and other equipment of the consumers: - (a) set-p boxes should not disrt, restrict or prevent competition in broadcasting or telecommunications services. The set-p boxes should not lead consumer choice being unreasonably constrained, whether in relation consumer equipment, the range of services available via that equipment or the packaging of those services; (b) set-p boxes should be equipped with by-pass outputs so that signals within the frequency range 50-862 MHz can by-pass the set-p boxes with minimum attenuation. The noise introduced by the set-p boxes should be as low as possible and should be less than 5 db; 30

(c) set-p boxes should be capable of operating on adjacent channels so that they will be compatible with the channel plan as proposed in paragraph 27; (d) set-p boxes should be tunable in the range of 54-862 MHz; (e) set-p boxes should be equipped with audio/video (A/V) outputs simplify the connection with the television set and other audiovisual equipment; (f) the above requirements should apply all new set-p boxes except: (i) the set-p boxes for digital terrestrial television services (additional requirements may be determined later); and (ii) the set-p boxes that are in use by existing licensees. Supply of Set-p Boxes 54. A set-p box normally provides two main kinds of functions namely security functions and non-security functions. Security functions refer the encryption of signals and conditional access the services and are for the purpose of controlling the access of the services by valid subscribers only. There is currently no common standard for the 31

security functions but it is likely that some common standards may emerge in the near future. Non-security functions refer functions for the normal reception of television programmes such as tuning capability, channel setting, audio and video outputs, etc. The existing set-p boxes used by the HKCTV mixed the security functions with the non-security functions hence it is not possible for other manufacturers produce the set-p boxes due the proprietary nature of the security functions. When a licensed pay television service operar adopts this kind of set-p boxes, the users will have no choice of set-p boxes when they subscribe the pay television service. The licensed pay television service operar will be the only supply source of set-p boxes. If the two kinds of functions can be separated, it will permit various manufacturers produce competitive set-p boxes with the non-security functions meet the market need. The set-p box may have a plug-in slot for the security functions. The security functions can be built in the form of plug-in cards or smart cards so that it can be inserted in a set-p box. This approach will benefit the users as they can have a choice of set-p boxes. This will also allow different service suppliers use the same set-p box but simply giving users different smart cards as plug-in. In order facilitate the emergence of a competitive marketplace for set-p boxes, it is proposed that:- (a) service providers should separate security functions from nonsecurity functions; (b) service providers should provide, upon request, technical information concerning interface parameters that are needed 32

permit set-p boxes operate with their systems and that consumers should have the right attach any compatible set-p box a service provider's system; (c) service providers are prohibited from taking actions which would prevent competitive supply of set-p boxes; and (d) service providers may not offer set-p boxes that have security and non-security functions integrated. 55. In order give suppliers sufficient time meet the requirements in paragraph 54 for set-p boxes, it is proposed that the effective dates for the application of requirements (a), (b) and (c) should be set at 1 July 2000 and for criterion (d) 1 January 2005. 56. To minimize the number of set-p boxes and simplify the connection required at the consumers 1 end, service providers are encouraged share a common set-p box for multiple services. This is a type of interconnection covered by sections 36 A, 36B and 36C of the Telecommunication Ordinance. The TA will encourage commercial arrangements be agreed between operars. If service operars cannot reach an agreement, the TA may be requested make a determination. The TA will publish additional guidelines at a later stage about this determination. 33

UPSTREAM SIGNALS 57. Usually the by-pass circuitry of a set-p box contains an amplifier. If two or more set-p boxes are connected in series as shown in Annex 13. upstream signal from the second or subsequent set-p boxes might be blocked by the first or preceding set-p boxes. There are two options resolve this problem and they are given in Annex 14. In option 1, a RF switch is added select the set-p box be used. Each time only one set-p box will be selected. Therefore, separate reception and recording of all the services is not possible. However, the loss introduced by the RF switch is low and the quality of the signals would not be significantly degraded by the RF switch. In option 2, a splitter is used split the original signal path in several parallel paths (in this example, the original signal path is split in three parallel paths and a 5.5 db loss will be experienced) for connection of the set-p boxes. Separate reception and recording of all the services would be possible but the loss introduced by the splitter have be lerated by all the services. It is proposed that either option may be adopted by the operars. COMMENTS AND PROPOSALS 58. The TA welcomes comments on this paper for the future arrangement of the IBCCDS in Hong Kong, especially on the following:- 34

(a) whether 8 MHz per channel plan should be adopted (c.f. paragraph 25(b)); (b) the proposal for the TA allocate the spare channels licensed service providers employing spectrum efficient technologies (c.f. paragraph 25(a) and (b)); (c) whether a fixed channel plan employing adjacent channels should be adopted and the preferred option (c.f. paragraph 27); (d) whether it is acceptable fix the channel numbers for the television programmes and reserve channel numbers 1 4 on set-p boxes for the four terrestrial television programmes (c.f. paragraph 28); (e) whether the proposed priorities for distribution in IBCCDS are acceptable (c.f. paragraph 32); (f) whether it is acceptable for the TA publish the database of IBCCDS (c.f. paragraph 33); (g) whether it is acceptable use a compression ratio of 6 or more for digital transmission (c.f. paragraph 36); (h) whether the proposed criteria for installing IF distribution system are acceptable (c.f. paragraph 43); 35

(i) whether the proposed criteria for installing parallel distribution network are acceptable (c.f. paragraph 45); (j) whether it is acceptable allocate the frequency band of 5-50MHz for upstream signal purpose (c.f. paragraph 46); (k) whether it is acceptable allocate the vacant frequency bands with bandwidths less than 8 MHz in 54-470 MHz for downstream signals of telecommunications services paragraph 47); (c.f.
