NASA TV's UHD channel will see the launch of an HDR version. According to Harmonic's Thiery Fautier it is the first lineair UHD channel over-the-top. Other lineair 4K HDR channels are available on satellite or cable platforms, not over-the-top like the NASA channel, that will be available through the Roku platform.
"The new UHD HDR channel is delivered over the top as an app utilizing a cloud-based end-to-end video streaming solution from Harmonic, Accedo, and CenturyLink. As the world's first 24/7 UHD HDR video streaming service, the channel will provide viewers with access to VOD and linear content", Harmonic in a statement distributed at its press conference.
The NASA 4K SDR channel has been in operation over satellite in North America, produced and managed by media technology vendor Harmonic, since 2015.
The new HDR version for global distribution will only be available online world wide on the Roku over-the-top streaming platform, to those have a Roku enabled device.
Bryan Walls, NASA Imagery Experts Program deputy programme manager, is "Happy to bring these wonderful images to the world, to every one without the need for a satellite dish".
He added that "we (NASA) have been producing pictures for decades, initially on film, we have been rescanning those, and some are in 4K quality. As video camera's advanced we have been switching to those. We have 4K, 6K camera's, we even have an 8K camera on the International Space Station, but it can be very hard to get these images out".
Hence the use of the Harmonic VOS 360 SaaS cloud based compression and play-out service. Using the Harmonic IQ software compression one is able to use lower bitrate than the 20-25 Mbit/s used for the satellite SDR version of the NASA 4K channel.
"We offer better quality at a lower bitrate", claims Harmonic's Vice President of Video Strategy, Thierry Fautier. Adding that the adaptive bit rate on the HDR version runs at ten to fifteen megabit per second.
Centurylink's CDN is used to distribute the stream. The Accedo One tools were used to build the app and user experience.
