2 about scte standards The SCTE Standards Program is dedicated to providing standards to help the cable telecommunications industry prosper. SCTE standards cover a wide range of industry needs from F connectors to protocols for high-speed data access over cable. Six of SCTE s digital video standards were selected as the core of the recent agreement between cable operators and consumer electronic manufacturers. SCTE is accredited by the American National Standards Institute (ANSI), recognized by the International Telecommunication Union (ITU), and works in cooperation with the European Telecommunications Standards Institute (ETSI). SCTE s Standards Program is made possible thanks to the generous support of our standards members (see page 8). SCTE s Standards Program is open to any individual or organization that is willing to participate and pay the membership fee.

3 from the engineering committee chair In the fourth edition of his classic text, Computer Networks, Tanenbaum notes that the home network for data will be the seventh item installed in the house, behind electricity, gas, phone, cable, water, and sewer. 1 Our industry is well-positioned for services on three of the seven, but the latest home network needs to be as stable as the others. It has to work for as long and with as much satisfaction as the other home necessities.a good way to insure that is with well-developed standards. We are well-positioned for this in the Society s Standards Program, with over 80 ANSI standards, and more than 120 supporting companies.you ll read more about this later in the report. Again we thank the many volunteers in the program for their professional contributions. The subcommittee chairs for their leadership, the many member companies for their support, as well as Steve Oksala and the standards staff for their hard work. Daniel J. Pike Chair SCTE Engineering Committee Chief Technical Officer Classic Cable 1 Andrew Tanenbaum, Computer Networks, Fourth Edition, Prentice Hall, from the vice president, standards Steve Oksala Vice President, Standards SCTE After 2001, I didn t think that we could do better but sure enough, the members, through their technical participants, set new records for completing standards. We are now approaching 100 SCTE standards, a milestone that we should meet in the first quarter of 2003.We are also recognized as a credible force in standards, not just in the U.S. (where we rank 23rd among ANSI-accredited organizations in number of standards), but also around the world through our contributions to ITU and our recent contributions to IEC. But most importantly, the ongoing work of the committee members and the clear value placed on that work means that we are fulfilling our mission of providing effective standardization services to the cable telecommunications industry. I also want to say a word about our staff. During 2002 we welcomed two new staff members Robin Burckhardt and Robin Fenton. Managing a small group with a 50 percent turnover is not something you look forward to doing, but they have made immediate and significant contributions to the program so that Ted Woo and I could continue to manage our responsibilities. Moving into 2003 we still have significant efforts going on in all technology areas, and we expect another bumper crop of standards in 2003.We really look forward to the continuing use of those standards by MSOs and vendors to improve the effectiveness of the cable industry. scte standards report Jan.

4 2002 standards achievements With increased standards and increased members we have a good combination. During 2002 the membership of the SCTE Standards Program rose to 128 members. In 2002 we continued the productive work begun in We continued to put an emphasis on completing all the processes and getting valuable specifications approved as SCTE standards.we began the year with 52 SCTE standards, 30 of them approved as American National Standards by ANSI. This was a significant improvement over our 2000 total of 12 and seven. But we did even better in 2002; the SCTE Subcommittees, Engineering Committee, and ANSI each approved more standards in 2002 than they did in the previous year. Standards STANDARDS APPROVED BY PERIOD Subcommittee Year Engineering Commitee 2002 ANSI The number of SCTE standards almost doubled going to 94, and the number of standards approved as American National Standards by ANSI nearly tripled going to 83. Standards STANDARDS APPROVED Year End Status On the operations side, we continued the work begun in The Standards Bulletin is published four times a year, supplemented by the Standards Report.We continued to improve our Web site by taking advantage of the new SCTE Web design and by adding new features such as the top ten standards based on the number of downloads from the Web (The most downloaded standard is SCTE 22 1, DOCSIS 1.0 Part 1: Radio Frequency Interface). We also added FTP sites for each subcommittee so participants can get documents without having to resort to . The subcommittees had anywhere from two to five face-to-face meetings during 2002, utilizing trade show venues (Cable-Tec Expo, NCTA National Show, the Western Show, and the Texas Show) as well as separate meetings in the U.S. and Canada. The reflector systems continue to be the core resource for technical work between meetings. The Construction and Maintenance Subcommittee even experimented with Web conferencing for one meeting, a tool that is likely to see more use in the future. The work of SCTE is done in the subcommittees where participants from all parts of the industry work together to develop consensus technical standards. The accomplishments of those groups during 2002 follow: Cable Application Platform Subcommittee (CAP) CAP swung into action during the second half of The group was established to move forward in the area of applications platforms when the technology stabilized, which it did during the year. In December, CAP approved its first standard, SCTE 90 1, Open Cable Applications Platform Part 1: OCAP 1.0 Profile. This will be an increasingly active area, with enhancements to the basic standard and harmonization efforts with other platform standards as well as existing SCTE standards. Approved by SCTE Additonally Approved by ANSI 2 scte standards report Jan. Dec. 2002

5 2002 standards achievements Construction and Maintenance Subcommittee (CMS) CMS started the year off with the release of the second edition of Recommended Practices for Coaxial Cable Construction and Testing, the companion to the previously published second edition, Recommended Practices for Optical Fiber Construction and Testing. They followed up with their first official standard SCTE 77, Specification for Underground Enclosure Integrity, which defines environmental and loading requirements. A new working group was also established within the CMS Subcommittee with the creation of working group six, Graphic Symbols for Cable Telecommunications. This new working group will update the joint SCTE/NCTA document, Graphic Symbols for Cable Television. This should become a new SCTE standard in 2003 and additional construction standards are also in the process of reaching completion. Digital Video Subcommittee (DVS) DVS was significantly recognized at the end of Negotiations facilitated by the National Cable & Telecommunications Association (NCTA) and the Consumer Electronics Association (CEA), resulted in an agreement between major cable operators and consumer electronic manufacturers on a national plug and play standard between digital cable systems and digital television products. This will facilitate the move to HDTV and enable digital television to televisions without set-top boxes. The Memorandum of Understanding (MOU), announced on December 19, 2002, requires conformance to the following SCTE standards and recommends that the FCC incorporate these standards in their regulations. SCTE 26, Home Digital Network Interface Specification with Copy Protection SCTE 28, Host POD Interface Specification SCTE 40, Cable Network Interface Specification SCTE 41, POD Copy Protection System SCTE 54, Digital Video Service Multiplex and Transport System for Cable Television SCTE 65, Service Information Delivered Out-of-Band for Digital Cable Television Three of these standards (26, 54, and 65) were produced during Another notable in 2002 was the milestone reached by the Digital Program Insertion Working Group and their standards SCTE 30, Digital Program Insertion Splicing Application Program Interface; SCTE 35, Digital Program Insertion Cueing Message for Cable and SCTE 67, Applications Guidelines for SCTE (new this year). In August, Cox Communications announced that by using SCTE 35 it had successfully opened its digital tier of channels to local advertisers in Orange County (Calif.) and was running live, revenuegenerating ads on the digital tier and breaking new ground in cable advertising. The system allows Cox to insert specific ads in specific networks carried by the operator, with an uninterrupted high-quality picture. It also allows the dynamic adjustment of the schedule for insertions, making it possible for the operator to take advantage of sports and other real-time programming. In addition, DVS completed other standards on the characterization and transmission of video in 2002 basic characteristics (SCTE 43); transmission of IP datagrams and carriage of asynchronous data services using MPEG 2 (SCTE 42, SCTE 53); out of band transport (SCTE 51 1, 51 2); and in-band data broadcasts (SCTE 80). Data Standards Subcommittee (DSS) DSS continued its work in the areas of cable modems (DOCSIS ) and real-time services over cable (IPCablecom) produced a significant milestone the first approval of DOCSIS standards as ANSI standards. SCTE also acquired the maintenance responsibilities for them. These include: SCTE 23 1, DOCSIS 1.0 Part 1: Radio Frequency Interface; SCTE 23 2, DOCSIS 1.0 Part 2: Baseline Privacy Interface Specification; and SCTE 23 3, DOCSIS 1.0 Part 3: Operations Support System Interface. At the same time, DSS moved forward with other DOCSIS standards, approving SCTE 23 1, DOCSIS 1.1 Part 1: Radio Frequency Interface, SCTE 23 2, DOCSIS 1.1 Part 2: Baseline Privacy Interface Plus and ANSI/SCTE 79 2, DOCS 2.0 Operations Support System Interface. The remainder of the 1.1 and 2.0 DOCSIS specifications should see standardization during scte standards report Jan. Dec

6 2002 standards achievements During 2002 DSS revised SCTE 24 10, IPCablecom Security Specification, and added four new parts SCTE 24 14, IPCablecom Primary Line Support;24 15, IPCablecom Interdomain Quality of Service;24 16, IPCablecom Management Event Mechanism; and 24 17, IPCablecom Audio Server. All of these are also international standards, passed by Study Group Nine of the International Telecommunication Union (ITU), as well as ANSI standards. DSS sent a number of additional IPCablecom drafts to ITU during 2002 where they will receive international consensus before returning to the U.S. for approval as SCTE and ANSI standards. Emergency Alert Systems Subcommittee (EAS) EAS continued to provide analysis and support for the Emergency Alert System, concentrating on the October deadline for small systems to implement Emergency Alert Systems. The group was originally expected to dissolve this year, but homeland security is likely to result in additional requirements for cable networks, so the subcommittee decided to remain active. Hybrid Management Sub-layer Subcommittee (HMS) HMS finished up its base standards by adding SCTE 25 4, Hybrid Fiber/Coax Outside Plant Status Monitoring Part 4: Power Supply to Transponder Interface Acceptance Test. But their primary work was the creation of the Management Information Bases (MIBs) that provide the specification of information in a manner that allows standard access through a network management protocol. The standards cover the SCTE root (SCTE 36); the HMS root within SCTE (SCTE 37); and the MIBs for the following: The properties that may be associated with each parameter (SCTE 38 1); The list of alarms detected by the transponder, as well as the SNMP trap generated for these alarms (SCTE 38 2); Common information about network entities such as name, model number, serial number, status, power level, etc. (SCTE 38 3); Information commonly available from HFC power supplies (SCTE 38 4); Information about HFC optical fiber nodes (SCTE 38 5); Information about the communication state of devices connected to the transponder (SCTE 38 7); Definitions used to maintain loadable firmware images on an HMS transponder (SCTE 38 8). HMS also broke new ground by formally submitting its three base standards SCTE 25 1, Hybrid Fiber/Coax Outside Plant Status Monitoring Part 1: PHY Layer; SCTE 25 2, Hybrid Fiber/Coax Outside Plant Status Monitoring Part 2: MAC Layer; and SCTE 25 3, Hybrid Fiber/Coax Outside Plant Status Monitoring Part 3: Power Supply to Transponder Interface to the International Electrotechnical Commission (IEC) for approval as formal international standards. The submission was initially approved by IEC Technical Committee 100 (Audio,Video and Multimedia Systems and Equipment) Technical Area 5 (Cable Networks for Television Signals, Sound Signals and Interactive Services) at its plenary in San Francisco in October, and is now out for national balloting. Approval is expected in March Interface Practices and In-Home Cabling Subcommittee (IPS) IPS concentrated on test procedures during the year, getting 14 test procedure standards approved in Areas of accomplishment included the following: Cable parameters bending radius (SCTE 39), velocity of propagation (SCTE 49), measuring regularity of impedance (SCTE 50), determining braid coverage (SCTE 51), center conductor bond to dielectric (SCTE 59), jacket web separation (SCTE 61), corrosion resistance (SCTE 69), and insulation resistance (SCTE 70). Device characteristics group delay (SCTE 45), AC to DC power supplies (SCTE 46), noise figure (SCTE 62), and test point accuracy (SCTE 75). Cable-connector interface axial load temperature cycling (SCTE 72) and insertion force (SCTE 73). IPS continues to be very active in these areas as well as ongoing work on product standards for cable, connectors, active devices, and passive devices. 4 scte standards report Jan. Dec. 2002
