2006 FIFA World Cup HD Video Contribution Network whitepaper
In 2006, for the first time, live, uncompressed HD video was available from every venue of the FIFA (tm) World Cup in Germany. This breakthrough in high- performance, wide-area networking has been made possible through the use of advanced fibre optic network interfaces that utilize standard terrestrial telecommunications systems and equipment.
This paper begins with a description of the basic architecture of the system. Some of the key new technologies that are used in this system are then described. The paper concludes with a discussion of the details of the system implementation.
MD8000: High capacity video/audio/data switching and transport system for all types of media signals
The MD8000 Media Transport System provides an unprecedented level of flexibility in content networking systems. No longer will users be faced with choosing between today’s widely available, high-reliability SONET/SDH network and tomorrow’s low cost, high-performance IP Core based systems. The MD8000 is designed to work transparently in both environments, even supporting simultaneous interconnections between both networking technologies to maximize media connectivity. In addition, the MD8000 is the only high-capacity media networking system that does not require proprietary switching elements at each network node – individual signals can be switched between paths by standard IP routers, giving system designers amazing flexibility to combine low cost, flexible MD8000 shelves in the same network as high-performance IP core routers and switches.
For point-to-point fiber optic connections, there is no better choice than the MD-003 series from Media Links. These units are easy to install, provide a range of signal interfaces, and provide error correction and status monitoring for every signal. The MD-003 Universal Video interface is a key part of this system, providing a single optical TX/RX card set for all types of video signals.
MD-003GETR: 4 Port Gigabit Ethernet Switch with Optical Uplink
The MD-003 GETR 4-Port Gigabit Ethernet Transceiver provides a cost effective, robust single card solution for converged broadcast network needs. This video-aware, layer 2 Ethernet switch manages bandwidth for multiple input ports, allowing a single high speed optical Gigabit Ethernet link to be intelligently managed. Video signals are given priority whenever they are active, while data can be transported on the remaining bandwidth. When the video signals are removed, data bandwidth is automatically increased.
Modern video installations depend on high-quality, high-speed data communications almost as much as they depend on video circuits. With the MD-003 E-TXRX and E-RXTX card set installed in an MD-003 chassis, many different types of Ethernet and IP traffic can easily be supported.
MD-2U-4002: HD Down Converter with Digital to Analog Conversion
The MD-2U-4002 provides high quality down conversion of HD-SDI (SMPTE 292M) signals and supplies two simultaneous output signals: an NTSC composite (EIA-RS170A) and an SD-SDI (SMPTE259M). Through the use of robust 32 tap FIR vertical and horizontal fi lters and 10-bit video resolution, Media Links can ensure the utmost level of video performance.
MD-2U-4001: HD Up Converter with Analog to Digital Conversion
The MD-2U-4001 Upconverter provides high quality conversion of NTSC composite (EIA-RS170A) signals or SD-SDI (SMPTE259M) signals to the common HD-SDI (SMPTE292M) video format. Two AES/EBU digital audio, two channels of analog audio and the embedded SD audio can be selected and embedded into the HD-SDI output.
Combining standard telecomm signals with uncompressed video transport has never been easier than with the MD-003 series from Media Links. With the MD-003 STM-1 TX and STM-1 RX, both SONET and SDH signals can easily be transported alongside a variety of video formats. Through the use of optical Coarse Wavelength Division Multiplexing (CWDM), multiple signals can be combined onto a single fiber with no interdependency, and each will arrive intact at the far end of the link because of forward error correction on every circuit.
Media Global Links Co., Ltd. (MGL), is a leading developer and manufacturer of broadcast network infrastructure technologies. Since its establishment in 1993, the Company has accumulated expertise in broadcast and telecommunications technologies by providing design and original equipment manufacturing (OEM) services for major players in the industry. This experience has spawned a high-performance, technically advanced product lineup with unmatched reliability that serves a wide variety of customer needs in the normally disparate fields of broadcasting and telecommunications.
HD-GigE: HD compression codec and IP Video gateway
The HD-GigE™ IP Gateway transports HD-SDI/SD-SDI/DVB-ASI signals over IP networks and offers a cost effective alternative to traditional video transport services. The flexible, HD intraframe compression codec produces a high quality video signal that can be transported over Gigabit Ethernet networks. Standard Definition and ASI signals are automatically detected and passed through transparently.
HD270 Coax: HD Compression Codec for 270Mbps Transport Circuits
The HD270 Coax™ compression and transport of HD-SDI signals over 270Mbps circuits with outstanding video quality at incredibly low latency. By utilizing field by field encoding, the entire codec process adds less than 10 milliseconds of end-to-end delay.
The MD6000™ provides high performance video transport system over SDH/SONET Networks. Advanced technologies, including error correction, hitless protection switching, and differential delay adaptation allow flawless transport of the most demanding types of video signals.
The MD-003 1RU™ hybrid frame supports both Media Links MD2000™ series signal processing modules and MD-003 optical video transport modules, making it the most versatile frame available. Two slots are available for signal processing which include the HD-270 Coax Compression Code for 270Mbps transport circuits, the HD-GigE Video IP Gateway, and Media Links full suite of HD and SD analog/digital up and down converters, frame synchronizers and audio embedders and de-embedders.
The MD-003 3RU™ frame provides a complete multi-channel, multi-service transport solution. This compact unit integrates video/data to fiber transmitters and receivers, in-band network management, CWDM or DWDM multiplexing and fiber protection switching into a single frame system. The use of internal, modular plug-in fiber connectors eliminates multiple frames, external fiber patch cords and patch panels and provides an extremely robust solution.
