Huntsville, Alabama, November 2, 2015
Marshall Space Flight Center.
At an event held on October 20, 2015, at Marshall Space Flight Center, NASA personnel conducted successful testing to verify interoperability between five vendor implementations of the Video Services Forum's (VSF's) 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 MPEG2TS, with audio and ancillary data and encapsulated in IP with FEC. The verification was necessary in order to include TR-01 as an acceptable technology for use with multi-agency spaceflight operations. We need to show more than one vendor implementation interoperating with each other , said Walt Lindblom, Video Engineer - NASA Imagery Experts Group. This was successfully demonstrated during our test this week .
The five vendors participating in the event were Ericsson, Evertz, Imagine Communications, Media Links and Nevion. 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 , said Brad Gilmer, Executive Director of the VSF. Of course, it was important that we proved to NASA that interoperability has been achieved. But perhaps more important is the speed with which this event came together - 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.
NASA is an active partner in the Consultative Committee for Space Data Systems (CCSDS). CCSDS includes all the major space agencies in the world. The Motion Imagery Applications (MIA) working group within CCSDS has developed a standard for video applications and operations for joint spaceflight missions, and there was an opportunity to add TR-01 to the standard as an accepted technology, but first, multi-vendor interoperability had to be demonstrated. Now that hurdle has been crossed, and it is anticipated that soon, CCSDS will open a path for TR-01 JPEG2000 systems to be used for space-based and ground operations worldwide.
