is an all-digital audio/video interface capable of transmitting uncompressed streams. HDMI is compatible with Highbandwidth Digital Content Protection (HDCP) Digital Rights Management technology. HDMI provides an interface between any compatible digital audio/ video source, such as a set-top box, a DVD player, a PC, a video game system, or an AV receiver and a compatible digital audio and/or video monitor, such as a digital television (DTV). is a video interface standard designed to maximize the visual quality of digital display devices such as flat panel LCD computer displays and digital projectors. It was developed by an industry consortium, the Digital Display Working Group (DDWG). It is designed primarily for carrying uncompressed digital video data to a display. It is partially compatible with the HDMI standard in digital mode (DVI-D). is a video signal that has been split into two or more components. In popular use, it refers to a type of analogue video information that is transmitted or stored as three separate signals. Component video can be contrasted with composite video (such as NTSC or PAL) in which all the video information is combined into a single line level signal. YPbPr is converted from the RGB video signal, which is split into three components, Y, Pr and Pb. Y carries luma (gamma corrected RGB) information. Pb carries the difference between blue and luma (B - Y). Pr carries the difference between red and luma (R - Y). Video Graphics array inputs are typically used to connect PCs to monitors, projectors or other screens. The type of cable used is a 15 pin VGA cable, which is the same type used to connect regular computer monitors to processors. 4

, abbreviated S-Video and also known as Y/C (or erroneously, S-VHS and "super video") is an analogue video signal that carries the video data as two separate signals (brightness and colour), unlike composite video which carries the entire set of signals in one signal line. S-Video, as most commonly implemented, carries high-bandwidth 480i or 576i resolution video, i.e. standard definition video. It does not carry audio on the same cable. Pin 1 GND Ground (Y) Pin 2 GND Ground (C) Pin 3 Y Intensity (Luminance) Pin 4 C Colour (Chrominance) is a 21-pin connector for connecting audio-visual equipment together. The SCART connector first appeared on television sets in 1977. SCART makes it easy to connect AV equipment (including TVs, VCRs, DVD players and game consoles). In essence, it gathers together various common analogue signal types into a single connector. Previously, each of these would have had their own socket, requiring a "spaghetti" type mass of leads. The signals carried by SCART include both composite and RGB (with composite synchronisation) video, and stereo audio input/output. The standard was extended at the end of the 1980s to support the new S-Video signals. In addition, a TV can be awakened from standby mode or switched to video mode through a SCART connector. is the format of an analogue television (picture only) signal before it is combined with a sound signal and modulated onto an RF carrier. It is usually in a standard format such as NTSC, PAL, or SECAM. It is a composite of three source signals called Y, U and V (together referred to as YUV) with sync pulses. Y represents the brightness or luminance of the picture and includes synchronizing pulses, so that by itself it could be displayed as a monochrome picture. 5

IR ( infrared) is a line of sight means of control. IR requires a receiver and transmitter. Two way IR control available with WS Products e.g.. Control of source and TV. IR is susceptible to Sunlight, Strong halogen lighting and Plasma TV screens as they can radiate Infrared. Electrical noise can also cause flaky or slow operation. in A/V terms is a 9 pin connection that permits 2 way communication between devices. For example; a Wyrestorm MX0606PP Matrix. This system is still widely in use today as its is so versatile and is utilised for 3rd party integration and control. RS stands for Recommended Standard. Typically, unless alternative methods of controlling the matrix are chosen or problems with device communication through the matrix encountered, basic operation is all that is required to operate your MX0606/0808-PP. However, the following information on advanced operation will detail how the matrix system can be configured and for advanced control and settings can be altered or data manually input should such problems arise, as well as configuring the system for third party control. Control of the matrix is possible through RS232 using third party control systems or the dedicated Wyrestorm COM CTL software included with your purchase (also downloadable from www.wyrestorm.com). Should third party control be required, please see below for control system configuration and hex code input. The RS232 connection on the matrix is female QB9 Users can use a USB to RS232 cable or a direct male to female serial cable. 6

- RJ45 connectors are a proven method for termination of data cables and it is the method of connection on Wyrestorm products that transmit long distance video and audio over cat5e /6 cables. Two configurations are used: 568B for UK Europe etc. 568A is more prevalent in the US. Correct and proper termination is essential for a stable data. stream is a large, diverse family of frame-based computer networking technologies that operates at many speeds for local area networks (LANs). The name comes from the physical concept of the ether. Ethernet has been standardized as IEEE 802.3. The combination of the twisted pair versions of Ethernet for connecting end systems to the network. An RCA jack, also referred to as a phono connector, is a type of electrical connector that is commonly used in the audio/video market. It usually terminates a coaxial cable. (2 core) with a left and right connection for a stereo pair A Jack Plug is a common audio connector it is still widely used, both in its original 1/4 inch 6.3mm size and in miniaturized versions. The 3 most common sizes are 2.5mm, 3.5mm and 6.3mm and usually come in 2 contact ( mono) or 3 (stereo) versions. is a standardized optical fibre connection system. Its most common use is in consumer audio equipment (via a "digital optical" socket), where it carries a digital audio stream between components such as Bluray, DVD and CD players. TOSLINK may use inexpensive 1 mm plastic optical fibre or it can use higher quality multi-strand plastic optical fibres or even quartz glass optical fibres depending on the desired bandwidth and application. 31 7

The design and layout are probably the most important factors when specifying an HD Video system. From a simple point to point extender set over cat5e/6 or a splitter system to a multi-room, multi-source installation a number of factors must be taken into account. How many rooms require HD video? How many video sources and type? What control do they require i.e. IR or RS232 Are 3rd party control systems required Where is the equipment located? How long is the run and how many cables are required? What is the cable route from source to TV? Upgrade/future proofing Failure at the first stage of design and specification may lead to costly and time consuming mistakes along with an unstable system. Always endeavour to ensure the customer is fully understanding of the system and its capabilities and wherever possible build in future proofing. Ensure High quality cables are specified and installed throughout. Be mindful of the distances involved and the route to be taken for cabling, Hi powered mains cabling, kinks, poor termination and over long cable lengths will impact on the systems operational stability. 8

Ensure the equipment is installed in an accessible ideally centralized location. The cable route is as short as possible. Ensure bends are kept to a minimum and with a large radius. Keep HDMI and UTP Cables away from mains wiring 300mm and above is the recommended distance with 150mm as the minimum distance. Do not kink, or tie in knots or cable tie too tightly. Ensure the cable/s utilised are reputable high specification brand with sufficient headroom (bandwidth) for existing and future formats ( 4k for example). Do additional ( duplicate cables) require to be specified for additional features or control additions in the future? 3 or more connections in the cable run can reduce the maximum transmission run by 10% ( i.e wall plates, couplers, switches patch panels) Patch panels can differ markedly on data rates ensure it has sufficient bandwidth for the high data steams required with HD Video content. 9

With any video distribution system the whole infrastructure is reliant on the cables quality and specification,length and termination. As the demand for higher resolutions in video, 3D capability along with High Definition audio, the data streams are increasing ; placing much more demand on the cables ability to carry the data at high speeds over long distances. HDMI Cables. The majority of todays HDMI cables are High Speed that are 3D compliant along with ARC ( Audio Return) and Ethernet capabilities, however do not assume that a high speed 1 metre cable that has a data rate of 19 Gbps will also apply to a 15 metre cable it is quite feasible that the 15 metre HDMI will only pass 2.25Gbps. So what does all this mean..? As the length of the HDMI cable increases its performance decreases with regard to bandwidth ( data stream) e.g. The longer 15 metre cable is unlikely to operate effectively with a Bluray 3D video as this may require in excess of 4.46Gbps bandwidth. This may lead to either no picture at all, inability to display 3D images, handshake issues, drop-out or speckles. Always ensure that the cables are kept to a minimum length and are ever kinked twisted or excessive stain is applied to either the HDMI plug on the cable ends or the socket on the source or TV/projector. Never Hot swap an HDMI cable (removing or inserting) whilst the source or TV/ Projector are switched on this may damage the delicate electronics and chipsets leading to premature failure or in some cases an immediate fault due to shorting of the pins. 10

All WS Products are designed to operate on cat5e/6 as well as cat7 WS recommends that UTP ( unshielded) type is installed such as solid core cat5e/cat6 UTP. Screened types ( STP/FTP) can be utilised however these cable types be problematic if the shielding is incorrectly or unterminated at the receiver end ( TV) this is more prone to EMF /interference leading to potential IR control issues and or image stability. TP = Twisted pair U = Unshielded F = Foil shielding S = braided shielding Stranded cat 5 is not recommended as it has poor bandwidth and can cause speckles and handshake issues. Solid cat5e is superior and a more stable transmission cable Cat6 has larger conductors which improves again on bandwidth plus has additional mechanical support provided by the inner core. Example home broadband may be 20mbs - 4K By 2K resolutions require 10.2Gbps; cat6 would be the cable choice in this instance. 11

The Wyrestorm range of Point to point Extender sets consist of a transmitter (TX) installed at the source end such as a Blu ray player and a receiver ( RX) at the playback end i.e. a TV or Projector over single or dual UTP cat5e/6 cable Coaxial or Fibre optical cable with transmission distances of up to 40 metres to 5KM depending on the transmission method and technology utilised. The Transmitter has an HDMI input from source and the Receiver has the HDMI out to the TV or Projector. Features such as IR control,serial Pass through and Ethernet capabilities are also incorporated (model dependent) with the required connections. The QI Point to point Extender set consists of a transmitter installed at the source end (TX) and a receiver ( RX) at the playback end i.e. a TV or Projector over a single UTP cat5e/6 cable up to a maximum transmission distance of 40 metres that also features 1 way IR control from the receiver to the transmitter or matrix as applicable. The receiver ( RX) is utilised with the QI Matrix as part of a 4 by 4 matrix system. The Pro series differs from the QI requires 2 UTP to facilitate Video and audio; UTP connection 1 carries the IR and HDCP UTP 2 carries the video and audio content. The single UTP version available does not offer IR control and only has a single UTP connection. Note a 2UTP Receiver can be used with 1 UTP cable in connection 2 but only with a UTP splitter or Pro matrix that offers single mode settings. 12

The EX-1UTP-IR-70PP HDBaseT Lite Point to point Extender set consists of a transmitter installed at the source end (TX) and a receiver ( RX) at the playback end i.e. a TV or Projector over a single UTP cat5e/6 cable up to a maximum transmission distance of 70 metres that also features 2 way IR control from the receiver to the transmitter or matrix as applicable. In addition these also provide serial pass through The receiver ( RX) is utilised with the PP Matrix as part of a 4 by 4, 6 by 6 or 8 by 8 matrix system. only The HDBaseT extender sets differ from the lite models offering 4 k resolution plus 110 baset Ethernet capabilities. The EX-1UTP-IR-100 HDBaseT Point to point Extender set consists of a transmitter installed at the source end (TX) and a receiver ( RX) at the playback end i.e. a TV or Projector over a single UTP cat5e/6 cable up to a maximum transmission distance of 100 metres that also features 2 way IR control from the receiver to the transmitter or matrix as applicable. In addition these also provide serial pass through either as an extender set or via the respective HDBaseT Matrices. The receiver ( RX) is utilised with the HDBaseT Matrix as part of an 8 by 8, 8 by 16 or 16 by 16 matrix system. The EDID versions adds edid management & the POE model Offers full 5 Play negating the requirement for power for the receiver. 13

The Wyrestorm EX-1COAX-IR-75 is a single cable point to point extender set that uses copper-core 75 Ohm Coax cable as a means of transmitting 1080p HD video@60hz 24 Bit Colour Depth and multi-channel audio on cable runs up to 60m with wide-band, two way IR control from either source or display location and includes switches for EDID management. The 3D variant due in 2013 will have a maximum transmission capability of 50 metres at 1080P. The use of Coax to distribute and control HD signals between sources and displays is effective due to the low loss at high frequencies, vital for the cable television, satellite television and cable modem installations it is typically utilised. BNC connection is provided for the coaxial cable along with HDMI In/Out and 3.5mm connectivity for IR TX/RX on both transmitter and receiver devices. In addition EDID dipswitches are provided for management of differing TV / Projector capabilities. 14

The Wyrestorm EX-1FIB-5000 is a point to point extender set capable of delivering high spec HD video and audio distribution over distances up to 5km (3.1miles) using single mode optical fibre as a transmission medium the extender sets also allow cascading for extreme transmission runs up to 35km. Designed for projects that require stable HD video @60Hz and HD audio distributed over great distances, the EX-1FIB-5000 is an excellent choice for large scale installations such as airports, shopping centres, factories, universities, or indeed anywhere that necessitates the reliable transmission of clear, uncompressed video/audio to single or multiple displays over distance that makes conventional UTP distribution unfeasable. only 15

The Wyrestorm EX-1COAX- IR-75 is a single cable point to point extender set that uses copper-core 75Ohm Coax cable as a means of transmitting 1080p HD video@60hz 24 Bit Colour Depth and multichannel audio on cable runs up to 60m with wideband, two way IR control from either source or display location. The use of Coax to distribute and control HD signals between sources and displays is effective due to the low loss at high frequencies, vital for the cable television, satellite television and cable modem installations it is typically utilised. BNC connection is provided for the coaxial cable along with HDMI In/Out and 3.5mm connectivity for IR TX/RX on both transmitter and receiver devices. In addition EDID dipswitches are provided for management of differing TV / Projector capabilities. 16

The Wyrestorm EX-1FIB- 5000 is a point to point extender set capable of delivering high spec HD video and audio distribution over distances up to 5km (3.1miles) using single mode optical fibre as a transmission medium the extender sets also allow cascading for extreme transmission runs up to 35km. only Designed for projects that require stable HD video @60Hz and HD audio distributed over great distances, the EX-1FIB-5000 is an excellent choice for large scale installations such as airports, shopping centres, factories, universities, or indeed anywhere that necessitates the reliable transmission of clear, uncompressed video/audio to single or multiple displays over distance that makes conventional UTP distribution unfeasable. 17

The Wyrestorm SP Range of Splitters enable the installer Split an HDMI source such as a cable box or DVD player and send that signal out through an HDMI Socket to a TV, projector or AVR. The maximum transmission length capabilities are dependent on the HDMI cable and as a guide 10 15 metres would be the suggested maximum length to provide stable operation. Longer length HDMI cables are available but, dependent on the quality of the cable may suffer from handshake issues especially with High definition Blu-Ray content as the source. Should longer transmission rates be required a Wyrestorm extender set ( point to point) can be utilised that also offer IR control over the source equipment. 18

WyreStorm's 4 and 8 Way Cat5e i /6/7 Splitters are cost effective replication and distribution of HD transmissions - ideal for small commercial and multi-dwelling installations. The SP-UTP-0104 and SP- UTP-0108 both offer single HD source distribution, providing uncompressed true HD distribution over long distances only using Cat5e/6/7 cabling, with the ability to control the source from display locations. Dip switches provide EDID management and single cable transmission if the IR feature is not required. The receivers utilised at the TV/projector are the Pro series RX 50 metre dual or single UTP models. 19

Switchers and scalers differ from both splitters and matrices offering different methods of source connection i.e. VGA in and output on HDMI. This allows the installer to offer a flexible solution for differing formats of source device either analogue or digital and be able to switch to different source inputs and output via HDMI. If long transmission lengths are required then a Wyrestorm extender set can be utilised on the output/s to provide additional flexibility in both the placement of the unit and accommodate display devices remote from the switch. Mid Range models offer manual and IR control for source selection, higher end models add RS232 control and up scaling capabilities for improved picture quality along with additional outputs. The 8:1 Multi Format Switch offers 8 inputs to one single HDMI output with manual source selection plus IR control. 20 The 11:2 is a switcher scaler offering comprehensive source switching outputting via HDMI. This model also provides up scaling of sources to 720 p or 1080p and also benefits from Ir and Serial control via the RS232 Serial port. The unit also automatically amplifies and equalizes signals to ensure the optimum HD transmission over the length of the HDMI cable without any loss in quality of picture or audio

An HDMI matrix switch will take video from 4, 6, 8 or 16 sources and distribute these sources using from 2 to 16 outputs dependent on model. Any source can be routed to any output so that each display can watch a different source simultaneously. Sources to the HDMI matrix switcher are via the HDMI input connections. To send video to a room that has a run of 10-15 metres an HDMI cable can be utilised from the HDMI matrix outputs to the display location; longer runs would require a different transmission cable such as cat5e or cat6 outputting from the UTP RJ45 connection (where applicable) or an extender set (if only HDMI outputs are featured on the matrix) with the matching receiver that converts the signal back to an HDMI output. only Standard/Compact matrices offer HDMI inputs and HDMI outputs with IR control of the matrix and Global IR source control. The Pro series of matrices utilise two UTP cables Port 2 carries the AV signal and port 1 carries the IR control and HDCP data. The Qi matrix offers UTP outputs with one way IR control of the matrix and routed Ir control of the sources via a single cat5e/cat6 cable up to 40 metres maximum transmission distance. HDBT and lite variants (PP) provide longer transmission distances over a single cat5e/cat6 cable with two way IR for Matrix, routed source control and display IR control up to 70 metres on the lite PP variants plus simultaneous HDMI outputs; the 6 by 6 and 8 by 8 PP models also support the TX format daughter cards and HDBT digital amplifiers. The HDBT matrices offer 100 metres transmission and 4K resolution capabilities in addition to serial and 100 mb of Ethernet but do not feature HDMI outputs both models have serial LAN and IP featured as control methods for 3 rd party control and integration. 21

Handshakes - problematic or slow handshakes may well be issues with EDID or HDCP however, it should be noted that a poor installation can also be symptomatic with handshakes. EDID or Extended Display Identification Data. A 127-bit data signal passed from the display to the source, communicating screen capability. This ensures that the correct resolution is transmitted to the TV i.e. 1080P WS Products have the ability to learn EDID data, Pass-Thru EDID or confirm Pre -Set EDID data back to the display this is an important feature when different resolution TV s and sources are combined especially through a matrix system. In simple terms the source equipment will communicate with the playback device such as an TV or Projector; based on the information received the source equipment will alter its output resolution and colour depth to match the capabilities of the TV or Projector. As an example installation with a Wyrestorm MX0606PP matrix, a Blu-ray player, Sky HD box, DVD player and satellite receiver. Four TV's at 1080P and one TV at 720P The matrix will automatically manage the EDID however, if all TV's were viewing a DVD the resolution would be 720p not 1080P as expected why? When a mixture of differing resolution TV s are viewing the same source it will manage the EDID to the lowest resolution in this case 720P. However Wyrestorm products offer extensive EDID management options to facilitate this please see the following excerpts from the MX0606PP operating manual. 24

ATTENTION: Changes to the DIP switch settings should be made with the matrix OFF, ideally with all power cables and HDMI leads and UTP cables removed to guard against electrostatic build up that may damage your system. DO NOT HOTSWAP your cables when changing DIP SETTINGS. ALL changes to the DIP settings become effective upon powering ON the matrix. Note: the shaded dip switch denotes an inactive switch so can be set up or down. only To copy the EDID from an HDMI OUTPUT display to a specific INPUT port, first set the DIP switch to this position. Then select the INPUT by pressing and holding the chosen OUTPUT SELECT button for 3 seconds for the EDID to be copied from the DISPLAY to the INPUT port. For example: If OUTPUT 3 is selected for INPUT 1, the EDID for OUTPUT 3 will be copied to INPUT 1 this is achieved by the system setting HDMI OUTPUT as a higher priority than UTP OUTPUT. If EDID copy is not successfully completed, the INPUT Port EDID will remain the unchanged. To reset EDID for all ports, simply set the DIP switch to the above position when the matrix is powered OFF. On powering ON, all ports will revert to the above factory default and DIP switches can be adjusted as necessary. For users who wish to copy EDID from an AV Receiver with 7.1 channel audio to a specific input port containing a Blu-ray player, follow a variation on the instructions above: 1 Set the DIP switch to the above position with the matrix in the OFF position. 2 Connect the AVR to your desired OUTPUT port on the matrix (for example, OUTPUT 2) 3 Power ON the matrix and select your INPUT your chosen SOURCE is connected to (for example, INPUT 3 Blu-ray) 4 Press and hold the OUTPUT SELECT button for 3 seconds for the EDID data to be copied from OUTPUT 2 (AVR) to INPUT 3 (Blu-ray). 25

Setting the DIP switch to this position will instruct the matrix to use embedded 1080p 3D compatible video and Stereo audio EDID to encourage communication between the matrix and 3D sources/3d displays if handshake problems are encountered. After setting the DIP switch, reconnect and turn on for the changes to take effect. The matrix will use embedded 1080p video and stereo audio EDID in this DIP setting. After setting the DIP switch, reconnect and turn on for EDID settings to take effect. In instances where a connected display is unable to achieve 1080p resolution (such as using older or cheaper models), this DIP setting will instruct the matrix to use embedded 1080i video and stereo audio EDID to output a signal. After setting the DIP switch, reconnect and turn on for EDID settings to take effect. When set to this DIP position the matrix will use embedded 1080p video with 5.1ch Audio EDID. After setting the DIP switch, reconnect and turn on for EDID settings to take effect. When set to this DIP position the matrix will use embedded 1080p video with 7.1ch Audio EDID. After setting the DIP switch, reconnect and turn on for EDID settings to take effect. Instructs the Matrix to Output a signal regardless of communication between display and source compatibility. This setting may be used to further encourage compatibility between devices if other DIP settings prove unsuccessful in establishing communication. 26

If you connect an HDMI-compliant next-gen DVD, Blu Ray player or Sky box for example to an HDMI-compliant TV or projector. Before sending its highest-res digital video to the TV, the source will insist on doing an HDCP handshake. The purpose of the handshake is for the two devices to authenticate each other, that is, to verify that the other device is an authorized HDCP device, and to compute a secret key, known to both devices, that can be used to encrypt the video as it is passed across the HDMI cable. If for some reason one of the devices does recognize the numbers or the additional rule is not within the TV or source then the handshake will not occur normally resulting in a blue screen on the TV or projector. only This is normally down to a current license/key not being present/valid and may be seen as a breach of copyright and not allow the signal to progress. If a 3 rd device is inserted between the source and TV such as an AV receiver or the increasing number of High Definition Splitters and Matrices then these also have to be capable of interpreting the secret vector and have the required rule. WS has all required licenses to analyse, pass-thru, repeat, replicate & generate HDCP keys WS has no known HDCP compatibility issues with any device. Higher end WS products support constant HDCP where new keys are internally generated to maintain seamless switching with no drop-out. See below an example installation showing HDCP in operation with the keys/ Licenses in the circuit from the SKY HD (source) through the WS 0104 HDMI Splitter to the TV. 27

The first example utilise an PP matrix to the HDBT digital amplifier driving a pair of speakers locally in the zone. The HDBT output then runs to the RX70 IR-PP receiver that sits at the display. This method allows long transmission runs up to a maximum of 7 HDBT devices from the output of the PP matrix either amplifiers, receivers or a mixture of the two. only The second example differs from the 1st in that one of the HDBT digital amplifiers is being utilised as a pre-amplifier stage to an AVR ( audio video receiver). This allows integration with a Home theatre installation for example the HDBT amplifier driving the speakers is for augmenting the TV audio; the 2nd HDBT amplifier Is utilised when watching a movie where surround sound and or higher sound levels may be desired. Volume, Bass Treble and mute functions are available via the remote control device... Including EDID copy and mangement Source selection is also available such as local audio input for the specific amplifier or audio and video content routed via the HDBT RJ45b input when viewing a Blu ray disc for example. 29
