example, the FOX 4G Matrix 14400 delivers 144x144 switching in just an 8U enclosure.
If your fiber optic matrix switching needs extend beyond 320x320, our new Extron Matrix 1K Program offers custom matrix switching solutions up to 1000x1000 and beyond. For more information, see the sidebar on the following page.
All FOX Matrix Switchers are fully compatible with FOX Series fiber optic transmitters and receivers for sending various analog and digital video formats. They also can be used with FOX Series switchers and distribution amplifiers to support localized switching and distribution off of the matrix switcher.
We’ve designed all FOX Matrix Switchers to deliver the switching capability to route video signals of the highest source resolutions, together with audio and bidirectional RS-232 control signals. And since these products are commonly used in mission-critical applications with continuous operational requirements, we’ve built in several features to ensure full system reliability with the ability to run 24 hours a day, seven days a week without a complete system shutdown.
In addition to high performance and reliability, we’ve also designed our FOX Matrix Switchers to be energy efficient with low power consumption.
Wide Bandwidth, Pixel-for-Pixel PerformanceExtron FOX Matrix Switchers are compatible with all FOX Series products including transmitters and receivers for
extending various video signals including RGB computer-video, HDTV, DVI, multi-rate SDI, and standard definition video. FOX Matrix Switchers represent the flagship of our FOX Series of fiber optic A/V products, and share our overall design philosophy of engineering for reliability and exceptional high resolution image performance.
Our FOX Matrix Switchers offer up to 4.25 Gbps digital switching capability for routing audio, control, and video signals with uncompressed, pixel-for-pixel throughput. With this level of performance, we can assure compatibility up to the highest source resolutions.
Modular Design for Future ExpandabilityAll Extron FOX Matrix Switchers feature a modular design with multiple board slots. Each slot accepts a FOX Series input/output board having ports populated with LC-type fiber optic connectors. Two versions of the board are available.

buildings or facilities with moderate-range transmission distances of several hundred meters or feet. The singlemode version supports singlemode as well as multimode fiber at 1310 nm. Singlemode fiber offers long-range transmission capability over extreme distances of several kilometers or miles. It is used in very large facilities such as hospitals and stadiums, and for connecting over very long distances between facilities such as university campuses.
Extron FOX Matrix Switchers can be configured with all or some of the board slots occupied. The I/O boards are hot-swappable and may be added at any time in the field for easy and quick upgradeability or expansion in 8 or 16-port increments depending on the model. A FOX Matrix Switcher also accommodates any combination of singlemode or multimode I/O boards. For the FOX 4G Matrix Series, the combination of singlemode and multimode I/O boards allows a multimode fiber link input to be routed to a singlemode output, and vice versa.
A FOX Series transmitter and receiver combination can send A/V and control signals up to 300 meters (985 feet) for multimode fiber, and up to 30 kilometers (18.75 miles) over singlemode fiber. With an Extron FOX Matrix Switcher in between a FOX Series transmitter and receiver, transmission distance capability can be significantly enhanced.
For example, a multimode transmitter sends signals up to 300 meters to the matrix switcher. The matrix switcher can then retransmit these signals up to an additional 300 meters to the receiver. However, the matrix switcher can also retransmit over one of its singlemode outputs to a receiver, located as far as 30 kilometers away.
Multi-Rate SDI Signal Switching and DistributionThe FOX 4G Matrix 3200 and 7200 models also offer an optional multi-rate SDI I/O board for connection to local multi-rate SDI-equipped devices in broadcast, medical, and other applications where SDI is common. This board offers an 8x8 configuration for switching and distribution of multi-rate SDI signals up to 2.97 Gbps, including SDI, HD-SDI, and 3G-SDI. With this board, the FOX 4G Matrix 3200 and 7200 can be configured as a dedicated multi-rate SDI matrix switcher, or for a combination of multi-rate SDI and fiber optic matrix switching. The multi-rate SDI I/O board is compliant with SMPTE 259M, 292M, 424M, and ITU digital video standards. The board is hot-swappable, and each input and output is individually buffered to maximize performance with virtually no crosstalk. To optimize SDI signal transmission to and from the board, input signals are automatically equalized, and output signals are reclocked. The FOX 4G Matrix 3200 and 7200 provide separate bi-level and tri-level references for correct vertical interval switch timing.
The multi-rate SDI I/O board enhances system integration possibilities with SDI-equipped devices in many ways. It enables a local BNC connection to the FOX HD-SDI Fiber Optic Extender for Multi-Rate SDI. Incoming multi-rate SDI signals from the FOX HD-SDI can then be routed to the board's BNC outputs, or through the fiber optic outputs to remote FOX HD-SDI units. Similarly, incoming fiber optic signals from the FOX HD-SDI can be output on fiber or BNC.
In broadcast and production applications, a multi-rate SDI-equipped FOX 4G Matrix 3200 or 7200, together with several FOX HD-SDI units, can be

used to route signals to and from local editing equipment. At the same time, it provides the capability to receive or transmit multi-rate SDI signals very long distances over fiber to devices in remote locations, such as cameras and production monitors.
Self-Monitoring and Hot-SwappableExtron FOX Matrix Switchers are designed for optimum performance and reliability in applications requiring continuous operations 24 hours a day, 7 days a week, such as in government, military, and medical installations. A real-time monitoring system continuously provides self-diagnostics of the I/O boards, fiber links, power supplies, internal fans, and general functions of the switcher. LED indicators on each I/O board provide a quick verification of input signal presence as well as the status of fiber links with the transmitters and receivers. Extron FOX Matrix Switchers can be configured to trigger an external control system or generate e-mail alerts when an inbound fiber link has been lost.
Each I/O board is hot-swappable so that the matrix switcher can be serviced or reconfigured without interrupting all signal routing by powering down the unit. The Extron FOX 4G Matrix Series also includes, as a standard feature, hot-swappable power supplies to ensure continuous, uninterrupted power. Also standard are hot-swappable fans to maintain continuous cooling. SMX System MultiMatrix models are available with a redundant power supply.
Energy Efficient Matrix SwitchersFiber optic matrix switchers generally have to be powered continuously, and an inefficient matrix switcher design, running 24/7 can easily incur significant energy costs. FOX Matrix Switchers feature an advanced, energy-efficient design with low power consumption. Even when
fully-loaded, they draw less power than comparable fiber optic matrix switchers.
We were able to achieve this through an efficient enclosure design and the careful selection of high quality, long-life electronic components, along with highly efficient, cool-running power supplies. This energy efficiency results in a dramatic reduction in heat generation and power consumption as it relates to the product itself and the air conditioning needed within the equipment room. Low heat generation and power consumption translate to a lower cost of ownership and also an increased product lifespan. Furthermore, FOX Matrix Switchers save valuable rack space with compact enclosure designs, and side-to-side air circulation so that no extra ventilation space is necessary above or below the matrix switcher.
Building High Capacity A/V Systems for Today and the FutureFiber optics has become increasingly popular as the medium for large capacity A/V systems with high bandwidth video requirements. A fiber optic-based infrastructure for A/V will today support all common video formats as well as the highest resolution requirements, and will continue to support evolving resolutions and formats into the future. Extron FOX Matrix Switchers are designed to serve at the heart of such systems, delivering the performance and reliability demanded for these installations, together with the adaptability to future system expansion needs and technologies.
When equipped with optional multi-rate SDI I/O boards, the FOX 4G Matrix 3200 and 7200 can be used to route signals to and from local SDI equipment over coax cables, while also providing the capability to receive or transmit multi-rate SDI signals very long distances over fiber optic cables using the FOX HD-SDI.

Transit System Successfully Implements A/V Communication System Using Extron MAV Plus Matrix Switchers
As digital technology continues to find its way into more and more A/V systems, it’s interesting to discover
applications where analog composite video is still the best choice for the job. One recent example of this involves
a particularly challenging installation of audio and video surveillance systems on thirty-four light rail vehicles belonging to
the GCRTA – Greater Cleveland Rapid Transit Authority. While there may be no such thing as a routine rail car install, the
unique requirements and complex logistics for this particular project quickly narrowed the field of interested integrators.
Among other requirements, the project called for each of 34 LRVs – Light Rail Vehicles to be equipped with wireless
color video transmission and recording, wireless intercoms, and an automated switching and control infrastructure. The
integrator, Doan Pyramid LLC, chose Extron to provide all of the matrix switching and audio amplification for this project.
The Communication ChallengeEach morning, rail yard workers assemble trains by linking up to three LRVs based on the anticipated passenger volume for a particular route. Unlike most rail cars, LRVs are designed to work as stand-alone trains or to work as part of a modular train comprised of up to three units. Because of this modular design, the LRVs are not equipped with front and rear inter-compartment doors, so there is no way to walk between them. There is also no built-in provision for inter-compartment communication. A passenger isolated in LRV #2 or #3 had no way of communicating with the operator in LRV #1.
The Security ChallengeThe GCRTA also requested that the new A/V system integrate a security system in which video feeds from all eight cameras in each LRV are recorded onto dedicated
DVRs. Between the safety and security requests, the GCRTA posed several A/V challenges that Doan Pyramid LLC was eager to solve.
The SolutionsDue to the trains’ modular design, there was no way to route cable between the LRVs. Electrical connections resided within the train couplings, but there was no room to integrate A/V communications into this system. At this point, with no cabling options, digital video transmission was ruled out. Douglas Fortney, Doan Pyramid's Lead Designer on this project, was forced to think about what could be done with analog composite video and wireless A/V transmission. “We [Doan Pyramid] love challenging wireless video projects like this, but there was more to this than assembling a secure, wireless video system," Fortney says. "We had to ensure uninterrupted communication
between vehicles traveling through all types of transmission conditions and capture all audio and video from up to 24 cameras per train to an on-board security system.” One of the first hurdles was planning for high-bandwidth video transmission. “We chose MPEG2 compression because, even though it requires more bandwidth than some other CODECs, it has no latency,” Fortney says. Zero latency was essential because this project required real-time communication via the cameras and intercom stations. The only way to make this wireless network successful was to manage bandwidth and control the number of signals sent at once. "We had to do a lot of work to get the packet size correct so that the packets didn't collapse the wireless network," Fortney says. "We finally dialed it all in and, boy, was that a moment to celebrate."
LRVs - Light Rail Vehicles are assembled each morning into trains consisting of up to three LRVs depending on projected passenger volume.
The Operator's cabin features a touchscreen quad-view display from which the Operator can initiate two-way communication with passengers.
Passengers rely on wireless voice and video to communicate to the train Operator.

MAV Plus 1616 V
Enter the MAV Plus“We used the MAV Plus to help control bandwidth requirements for A/V over the wireless network,” says Fortney. “That way, we were able to transmit only the video and audio signal we needed, and nothing more.” When a passenger presses the intercom button, the train’s control system identifies the camera tied to that call box, and the MAV Plus routes the selected video and audio directly to the operator if the passenger is in the same train car as the operator. If the passenger is in a different LRV, video and audio are routed to the local MPEG2 encoder, and transmitted wirelessly to the operator in Car #1.
The Quad DisplayBecause each LRV is equipped with eight separate cameras and space is limited, Fortney designed the operator’s touchpanel with a quad picture display. When the train is stopped and the doors open, the operator sees only the exterior door cameras; once the train is in motion, the operator’s view switches to the interior cameras. Fortney and his team designed the system so that the video signals are first routed from the MAV Plus through the PIP processor, and then the output of the processor is then routed back into the MAV Plus as a separate, combined input signal. “This allowed the PIP to ‘live’ within the MAV Plus,” Fortney says. “We send the output of the PIP processor back into the matrix so that the PIP view could be sent where it’s needed.”
Fortney elaborates on the quad-display signal distribution: “In a typical three-LRV train configuration, we have all three 16x16 MAV Plus units, one per LRV, managing the four pictures in the quad PIP processor which are routed to the operator’s touchpanel controller. The operator can touch any one of those four pictures and the view he touches will appear full-screen. When this happens, the MAV Plus switches from sending the PIP signal to just sending the full screen video of the chosen view.” This all happens without interrupting the DVR, which is recording directly from the MAV Plus on eight dedicated outputs, one for each of the LRV’s cameras. “This is a good example of why the MAV Plus is a crucial component within the system. We’re able to manage our wireless network bandwidth effectively, without compromising the security of the passengers or the quality of the recorded video signal.”
Intercom AmplificationWhen it came to voice communication, Fortney's team knew that standard intercoms wouldn't suffice in this environment, so they designed enhanced call boxes. These call boxes house special microphones and dynamic, high-powered speakers designed to overcome the ambient noise aboard the trains. Extron MPA 181T power amplifiers provide intercom application. "We chose Extron amplifiers because we needed close to 95 dB SPL in order for the voices to be heard over the custom call box speakers.
The compact size of the MPA amps, their low power consumption, and minimal heat output made them perfect for this application." There was also an issue of echoes generated between the speakers and the microphone. The outboard DSP handles this challenge. "The microphone signals from the call boxes are sent to the acoustic echo and noise cancellation unit, then on to the Extron MPA amplifier, and that’s what’s driving the speakers at the volumes we need," Fortney says.
The camera mounted above the call box provides real-time video to the train operator who can quickly assess the situation based on both audio and visual information within the LRV. Once a passenger initiates a call, the operator's quad view display converts to a single video display showing the feed from the call box camera. During the communication, a red light on the call box lets the passenger know that video is being sent to the operator. "This helps reassure passengers that the operator is fully aware of any situation within the LRV," Fortney says.
The Bottom LineWhen asked how the system works, and if the GCRTA is happy with the results, Fortney gives an unequivocal "Yes." He adds, "We are just finishing the last train now, and the first one we finished has been in service for about one year. It's been performing very, very well, and the GCRTA is quite pleased."
The compact size and low heat output of the Extron MPA 181T mono power amplifiers made them a perfect choice for the small equipment enclosures on each LRV.
The MPA 181T has now been replaced by the MPA 401, a 40 watt ENERGY STAR® Qualified amplifier.

DRM for the A/V Professional
DRM - Digital Rights Management is used by owners and holders of intellectual property to enforce restrictions on
the use of their copyrighted content. In the A/V industry, DRM is used to secure digital music and video content
to prevent unauthorized playback or copying. For digital video content protection, the most prevalent DRM systems
are HDCP - High-bandwidth Digital Content Protection, and AACS - Advanced Access Content System. HDCP is an
encryption protocol applied to digital interfaces including HDMI, DVI, and DisplayPort. AACS is a standard for encrypting
high definition optical discs that also works in conjunction with HDCP.
DRM exists to protect the rights of content creators and owners to receive compensation for their initial ideas and subsequently bringing them to market. Movies and music are the most recognized source content within the A/V industry that is impacted by DRM enforcement. An individual who purchased a copy-protected Blu-ray Disc, for example, is entitled to utilize that disc only within a personal-use environment, which extends to the home or other private viewing locale. For that movie to be played in a public space, additional licensing requirements must first be met. If that licensing has not been obtained, significant fines can be levied against the offender. These fines may very well extend to the owner of the installed system.
A/V systems in public spaces are the center of our industry, with installations taking place on a daily basis. It is for this reason that DRM considerations must be made and addressed at the earliest point of system design. The time when needs are being assessed for an A/V integration project is also the time to determine the functional requirements of a given system. This is when the sales engineer should ask the right questions and inform the prospective customer on the legalities involved with personal-use devices and/or material being used in public and commercial spaces. The old, familiar adage of “Just because one can, doesn’t mean one should” is fully appropriate in this case. HDCP-compliant systems are increasingly being requested by customers and integrators alike. This type of system could be used to show protected content
in public spaces. Therefore, users should be made aware of the potential issues that may arise from inadvertent public display of private-use, content-protected materials. During system commissioning and training, the integrator should consider educating system operators, and even include discussion of DRM and content protection within system documentation. Of course, this is not as much of an issue for residential installations, where the entire system is generally intended for personal use.
HDCP and AACS – Separate DRM Protocols That Work TogetherHDCP is designed to prevent unauthorized access of protected video content and to enforce restrictions on authorized playback. HDCP-enabled video sources, such as Blu-ray Disc players, PCs, and other digital media devices, always undergo a three-step process to protect the video from unauthorized access:
1. Authentication: The video source determines that all devices connected to its outputs are authorized and able to receive encrypted video. This is accomplished by means of an initial authorization handshake protocol, where cryptographic public keys, KSV - Key Selection Vector, and encrypted messages are exchanged between the source and the downstream devices connected to its outputs. The HDCP 1.3 specification calls for a maximum of 127 simultaneous devices connected downstream from the source, and up to seven allowable levels of repeater devices between the source and the display - also
known as the sink. The source uses the initial handshake protocol to determine that these system size restrictions are not violated. HDCP version 1.3 is the currently implemented specification. As will soon be discussed, the latest version, HDCP 2.0, further restricts the allowable maximum number of simultaneous devices and repeater levels.
2. Content Encryption: After the source authenticates that all downstream devices are HDCP compliant and in good standing, and that no system size restrictions are violated, the source sends encrypted video downstream. The source periodically revises the encryption key for the video as an additional security measure.
3. Renewability: Since HDCP relies on digital encryption using secret keys, the system can be circumvented if the secret keys residing in HDCP-licensed products fall into the wrong hands. Therefore, a means has to be established to revoke any compromised keys. The HDCP administration authority, Digital Content Protection, LLP can add a list of public keys of compromised products to video content such as Blu-ray Disc. Video sources will read this data, store it in non-volatile memory, and compare the public keys of any downstream devices against this revocation list. If any key matches, no video will be transmitted.
Figures 1 and 2 on page 14 provide a step-by-step illustration of the communications that occur between source and sink devices within an HDCP-based system.

Table 1. Major changes in HDCP 2.0
The multi-step process of HDCP authentication can take several seconds to complete. This is a primary reason for the perceived sluggishness of some digital video systems, especially during startup and when video signals are switched or re-routed, requiring HDCP re-authentication. The best switching performance can be realized in HDCP-compatible video equipment built to minimize re-authentication through careful internal design and proper deployment of HDCP processing components.
The HDCP standard was greatly revised in October 2008 with the release of HDCP 2.0. Subsequently, in May 2009, HDMI 1.4 was released, but did not call for compatibility with HDCP 2.0. At this point, the timing for products to adopt the HDCP 2.0 standard is uncertain.
Until the introduction of HDCP 2.0, the basic protocol of HDCP had not changed substantially. The only major differences between HDCP versions 1.0 through 1.3
is in the types of physical A/V connections. HDCP version 1.0 applied to the DVI interface. Version 1.1 incorporated HDMI, and support for DisplayPort was added for version 1.3. With the release of version 2.0, HDCP became interface-independent, and can be applied to any two-way digital transmission between sources and displays, wired or wireless, compressed or uncompressed. See Table 1.
HDCP 2.0 calls for many other important changes. For wireless connections, HDCP 2.0 adds a locality check to the authentication protocol, to ensure that only devices nearby will be able to receive protected content. Furthermore, HDCP 2.0 replaces the specialized 56-bit HDCP 1.x encryption scheme with two standard algorithms from the data security industry: for authentication, an RSA system with 1024 and 3072-bit keys; and for content encryption, a 128-bit AES - Advanced Encryption System. In addition, the maximum number of connected devices is reduced to 32, and the maximum level of
repeaters is reduced to four. As a result of all these changes, HDCP 2.0 is not directly backward compatible with HDCP 1.x. The new specification provides for converters between HDCP 1.x and HDCP 2.0 devices to support mixed A/V systems with devices that comply with both versions. An existing A/V system incorporating HDCP 1.3 will require converters if newly acquired HDCP 2.0 devices are to be incorporated into the system.
AACS is the DRM standard adopted for Blu-ray Disc. AACS is designed to protect Blu-ray Disc content similar to the way that the CSS - Content Scramble System protects commercial DVDs, but with additional features. Both AACS and CSS encrypt the video data on-disc, so that only authorized players can read the content. See Table 2. Both AACS and CSS prevent unauthorized copying of commercial Blu-ray Disc and DVD, and both systems have mechanisms for revoking compromised players. AACS offers greater protection than CSS in the following areas:

• AACS employs AES 128-bit encryption, while CSS implements 40-bit encryption
• AACS allows for the revocation of individual Blu-ray Disc players, whereas CSS can only revoke entire models of DVD players
• AACS encrypts the digital outputs of Blu-ray Disc players with HDCP
• AACS provides for the eventual elimination of analog video outputs on Blu-ray Disc players
The final AACS specification will include a provision for making authorized copies of Blu-ray Discs, whereby a recording device can connect to Internet servers at the AACS LA - AACS Licensing Administrator to obtain electronic permission to make a legitimate copy of protected content.
Analog OutputsThe HDCP licensing agreement does not allow for analog video outputs on repeater or display devices, but does not restrict analog outputs for sources. Nonetheless, this does not preclude separate agreements that would prevent analog outputs on source devices. Such agreements could be negotiated on an ad hoc basis between content providers and hardware makers.
However, the AACS licensing agreement is very specific about analog outputs and provides for several measures to control them. Blu-ray Disc titles that support AACS have usage rules data embedded in them that allow the content producer to limit the analog output resolution by invoking the ICT - Image Constraint Token, or even to disable the analog outputs entirely by invoking the DOT - Digital Only Token. As of the fourth quarter of 2009, no Blu-ray Disc titles have included these restriction tokens, but this may change with future releases. The AACS license agreement also provides for an “analog sunset” for newly manufactured Blu-ray Disc players, such that models manufactured after 2010 can only include standard definition analog outputs, and after 2013, no Blu-ray Disc players may be manufactured with any analog outputs.
ComputersThere are numerous DRM schemes for computers. The computer industry is a major source of innovation for content creation as well as for unauthorized reproduction of that content. Computer DRM methods have been devised to protect software, digital music, digital video, digital books, games, etc. The present discussion will be limited to video content played on a computer and the associated DRM schemes therein. These DRM schemes are mainly for preventing unauthorized access to protected commercial video such as Blu-ray Disc or downloaded content including movies or TV shows. But non-commercial video files can also be protected with DRM, if the content creator has access to DRM technology. The DVI, HDMI, and DisplayPort outputs of computers should have no DRM restrictions when the content being played is not protected.
As of the fourth quarter of 2009, for Blu-ray Disc playback, only PCs running Windows® operating systems have software authorized to play Blu-ray Discs. The same AACS and HDCP restrictions apply for PC Blu-ray Disc playback as for standalone players. Thus, a PC must be equipped with a video card that is capable of HDCP encryption. An A/V device with digital video inputs must support HDCP, if a user expects to connect such a PC to it and play commercial Blu-ray Discs.
The market for authorized downloads of commercial video content is crowded with companies and products, with frequent turnover of market entries and exits. Current market players include Amazon, Apple iTunes, Blockbuster, Netflix, and Vudu, to name just a few. These companies offer a plethora of options for the end user. Movies or TV shows can be rented or purchased, some in high definition, but most in standard definition. The video may be either streamed or stored locally to a computer, a networked set-top receiver, Blu-ray Disc player, a video game console equipped with
a hard drive, or even a display with Internet access capability. The one constant among all these different options is the existence of DRM for protected content, which is used to restrict the allowable viewing duration of “rented” video content and the ability to transfer the video to different computers. In the case of protected HD video downloads, HDCP support is required on any device that is playing the video. Therefore, a display with digital video inputs must support HDCP, if a user expects to connect a computer to it and play downloaded commercial HD content.
ConclusionAny A/V system that is intended to support playback of protected video content, such as Blu-ray Disc and consumer-purchased HD video downloads, must be compliant with the associated DRM. Since DRM implementations such as HDCP and AACS are meant to restrict what the end user can do with protected content, it makes sense for the A/V professional to inform the end user of these restrictions at the outset. Such restrictions include limiting the number of simultaneous displays for content-protected video playback, disallowing recording or copying, and disabling analog outputs. For example, an A/V system may have the capability to distribute HDMI video to 16 displays and provide analog video recording. These functions will always be available when a PC with HDMI output is connected for PowerPoint presentations and other non-protected material. But once a protected Blu-ray Disc is inserted into the PC for playback, HDCP and AACS restrictions may disable output to several displays and to the recorder.
Since many large-scale A/V systems can display unencrypted video on a large number of displays, freely distribute analog signals, and provide video recording capabilities, end users of such systems must be made aware that some system functions may not be available when playing DRM-protected content.

Using Extron EDID Manager to Identify and Troubleshoot Display Connectivity Problems
EDID - Extended Display Identification Data exchange is a standardized means for a display to communicate its
capabilities, such as its native resolution, to the attached source device, which then generates the necessary video
characteristics to match the needs of the display. When successful, EDID exchange maximizes functional compatibility
between devices, helping to ensure optimal image quality as well as overall system reliability.
However, this data exchange often is not successful. The implementation of EDID for display devices varies widely, and in some cases, displays lack EDID information altogether. Such inconsistencies can cause operational issues ranging from overscan and resolution problems to the display device not displaying any image at all.
If you’re encountering such problems, we’re pleased to offer a convenient software application, Extron EDID Manager, which can be used to help determine whether EDID incompatibility may be the cause of an image display issue. With this software, you can directly view the contents of the EDID file from a display device. EDID Manager is available as a free download from www.extron.com.
How to Use Extron EDID ManagerDownload and install EDID Manager on a Windows® PC. If the PC isn't the source device, you’ll need to disconnect the source from the display device, and connect the PC to it. EDID exchange applies to VGA, DVI, HDMI, and DisplayPort, so it may be advisable that the same connection from the source be applied from the PC as well. Once connected, the PC will attempt to capture EDID from the display. Before running EDID Manager on your PC, reboot the computer first, which will help ensure that the EDID captured was saved to the registry.
Reading and Interpreting EDID DataEDID is a data structure organized into several blocks of data, each revealing pertinent information about the display device and its operational characteristics. For computer-video applications, EDID is generally 128 bytes. For digital video interfaces including DVI, HDMI, and DisplayPort, EDID includes the CEA-861 extension data with 128 additional bytes of information relating to HDTV rates, audio formats and channels, and other video attributes.
By default, the software gives you the option to view the data, block by block, in full detail. Select the “Full View” tab, and you’ll see a complete report of what’s in the EDID file. EDID Manager offers the option to save the report to a file.
Confirm that you're accessing the correct EDID, by checking the manufacturer name and model of the display in bytes 90-107. If you don't see the correct name and model, it’s possible that no EDID was communicated to the PC. This could be

T E C H C O R N E R
a situation in which the display failed to generate any EDID information at all, or for some reason the PC could not read the EDID information.
Scroll up to bytes 54-71, and you’ll find what is perhaps the most important information about the display: the video signal rate it prefers to receive from the source. This preferred rate generally includes the native resolution of the display. In applications where a PC is connected to a monitor or projector, the resolution for the graphics card should always be at this preferred rate to ensure optimal image quality. If you had been seeing fuzzy, distorted images from the source PC, chances are that the graphics card had been set to a different output than what is preferred by the display.
If the source is DVI or HDMI-equipped, such as a Blu-ray Disc player, and the display is an HDTV, try to find the CEA-861 extension data in bytes 128 to 255. If no CEA-861 data is found, the display may be a legacy model with limited HDTV compatibility.
Resolving EDID-Related Compatibility ProblemsIf the EDID file reveals a discrepancy between the rates accepted by the display and what’s coming out of the source, there are several ways you can try to resolve the issue. A first step could be to attempt to set the output of the source to match the display’s preferred rate, or one of the other rates it will accept. If the source is a PC, and the rate you want isn’t available as an option, you can first try to update the driver for the graphics card.
These measures will fail to resolve the problem if the PC overrides your settings and forces its own default resolution, such as 640x480. In other cases, the PC or some other source simply won’t output anything at all.
For these situations, the solution would be to connect an EDID emulation device, such as the Extron EDID 101D or EDID 101V, to the output of the source. This device communicates the EDID data the source needs to provide the proper video output. Extron EDID 101 devices feature EDID Minder™ which provides constant and continuous EDID data management with the source. The devices generate emulated EDID based on a user-selected resolution and a refresh rate, or EDID captured and stored from the display device.
Using EDID Manager in A/V SystemsIn addition to displays, other devices within an A/V system may communicate EDID, including switchers and video scalers. EDID Manager can be used to check for possible EDID discrepancies between the display and these mid-stream devices.
The display's EDID can be used as a reference in setting up products that can generate emulated EDID, such as those from Extron featuring EDID Minder. These products can be particularly effective in A/V systems with a twisted pair, fiber optic, or traditional RGBHV infrastructure that do not convey EDID from the display back to the source.
A Common EDID-Related Problem: Audio IncompatibilityAlthough mostly associated with video,
Extron EDID 101D Emulator with EDID Minder™
audio problems may also occur due to EDID issues between HDMI-connected devices. The CEA-861 extension data lists audio formats supported by the device as well as the speaker assignments for the audio channels. Ideally, the source should read the display's EDID and then send its audio output in a format compatible with the display.
Unfortunately, this often is not the case. For example, a Blu-ray Disc player is sending content to a display. The picture is fine, but there is no sound from the speakers. The EDID indicates that the display only accepts two-channel audio. However, the Blu-ray Disc player is overriding or ignoring this information, and instead is sending Dolby® Digital 5.1 multi-channel audio, which the display is unable to decode. To resolve this issue, the Blu-ray Disc player should be reconfigured so that it outputs two-channel audio to the display.
The source resolution matches that of the display, so that the image is displayed correctly.
The source resolution does not match that of the display, resulting in a fuzzy, distorted image.
