NEWS MOVE & DELIVER To boldly go where no man has gone before… to a world where broadcast technology is truly interoperable. Seriously. It might sound like science fiction but the final frontier of television technology might finally have been reached: by NASA (hence all the corny space references in this terrible intro). At an event held in October at the Marshal Space Flight Centre, NASA personnel successfully tested interoperability between five vendor implementations of the Video Services Forums (VSFs) Technical Recommendation 01 (TR-01). TR-01 uses existing standards to define interoperable profiles for real time streaming of a broadcast profile JPEG 2000 codestream wrapped in MPEG2 TS, with audio and ancillary data and encapsulated in IP with FEC. That is the science bit. The verification was necessary in order to include TR-01 as an acceptable technology for use with multi- agency spaceflight operations. But it is relevant for television because the five vendors participating in the event were: Ericsson, Evertz, Imagine Communications, Media Links and Nevion. Names you will know well. The source material provided by NASA was encoded at 720p/59.94 Hz. Tests were conducted at a wide range of bit rates, and multiple vendors were able to decode images at bit rates as low as 20 MBits/sec. “The verification of interoperability at this event is significant for several reasons,” says Brad Gilmer, executive director of the VSF. “Perhaps most important is the speed with which this event came together. It was a little over a month from the first request from NASA to having five vendors together in a room demonstrating interoperability. That is amazing, and is an indication of the level of interoperability that has been achieved, but also shows the commitment of these vendors to supporting truly interoperable technology.” For the television industry this could provide a new hope (yup, that’s another space reference right there). A hope that one-day all technology will work together in harmony. To quote Mr Spock: “The needs of the many outweigh the needs of the few.” Never has that been more accurate. JPEG 2000 Wireless transmitters Two-way wireless HD-SDI transmitters from IDX are at the heart of a remotely controlled video capture system recently completed for Cricket Ireland. Each CW- F25 transmitter is configured to carry data from a compact control unit to a remote television camera with an integrated motorised pan/tilt/zoom head. Full 1080i HD video is simultaneously carried back wirelessly from the cameras to a Panasonic AW-HS50 production mixer. Cricket Ireland assistant coach and performance analyst Peter Johnston said: “We needed a system which would allow us to stream live television coverage of matches over the Internet while also benefiting our performance analysis for the players. A vital requirement was the freedom to place cameras at any location without worrying about power supply cables or signal feeds.” D+P Multimedia Products designed the set-up which is based around Panasonic AWHE40S compact pan/tilt/zoom cameras. idx.tv 28 | KITPLUS - THE TV-BAY MAGAZINE: ISSUE 108 DECEMBER 2015 NASA has successfully tested interoperability between five vendor implementations of the Video Services Forums (VSFs) Technical Recommendation 01 (TR-01).
