Visionary IPTV encoders clock up 10 years on space station

Visionary’s AVN443 H.264 (PacketTV IPTV) encoders have completed a decade of service onboard the International Space Station (ISS).

They have played a pivotal role in the High Definition Earth Viewing (HDEV) project, which has brought breath-taking live video of Earth to more than 318 million viewers worldwide.  

The aim of the HDEV project, which was initiated by Nasa, was to test how commercial-off-the-shelf cameras perform in the challenging conditions of space, aiding in the selection of video systems for future spaceflights.

Visionary’s encoders – which have highlighted the role of innovative AV technology in making space more accessible to the public – seamlessly encoded video feeds from multiple cameras mounted on the ISS, transforming raw data into a format suitable for live streaming.

They were specified for their robustness and compression efficiency, ensuring that high-definition video can be streamed live without overwhelming the ISS’s bandwidth capabilities.

Designed for a mission life of a few years, the PackeTV IPTV encoders’ engineering has provided a high level of durability the extreme temperatures, microgravity and radiation encountered in space.

The encoders’ longevity has provided continuous data and insights into the effects of space on electronic equipment. This invaluable information contributes to the development of future space technology, ensuring that equipment can withstand long-duration space missions.

The clarity and detail of the images captured through the encoders have contributed to environmental monitoring and disaster response, enhancing our understanding of Earth’s dynamic systems.

The HDEV project has also transcended its original mission to become a powerful educational tool. Live streams of Earth have provided an unprecedented resource for educators worldwide, making space more accessible and inspiring to students.
