Sencore and Visionary Solutions Supply NASA
May 16, 2012
SANTA BARBARA, CALIF.: Visionary Solutions announced that NASA has
chosen the company’s AVN443 encoder to transmit HD video signals from the International
Space Station to Earth, providing NASA with a real-time video signal that will be
used to produce coverage of missions and events, documentaries, archival video,
and other unique programming for NASA TV.
NASA is upgrading
its internal cameras onboard the International Space Station to commercial standard
720p/1080i formats, thus requiring new encoders capable of transmitting a high-definition
signal. Through a combination of Visionary Solutions H.264 hardware compression
and transmission technology, the AVN443 encoders provide an HD, full-frame rate,
IP video stream from within the ISS, as well as an external view of the ISS and
a view of Earth.
Prior to being installed
aboard the ISS, the AVN443s survived a rigorous evaluation, including radiation
tolerance testing. The AVN443s installed onboard the ISS are currently the only
encoders certified for spaceflight.
Paired with Sencore’s
MRD 3187B modular receiver decoders, the AVN443 encoders compress the video signals
from multiple high-definition video cameras onboard the ISS. The Sencore MRDs receive
the IP video streams back on Earth and decode them into HD video feeds for NASA’s
monitoring and rebroadcast use. The modular architecture and multichannel capability
of both products provide a space-saving and bandwidth-efficient solution to the
challenges of delivering multiple high-quality HD video services from an orbiting
