NASA UHD is back on air again just checked and boom it works - hurray ! Hope it will stay longer this time
Last two updates from reddit topic this month:
UPDATE: 20 Mar 2022, we've installed a Harmonic ProView 7100 at our satellite dish location in Eugene, OR. This receiver is performing far better than the previous "GT Media" IRD that we had began this project with, and of course resolves the 'blips' we had every ~26 minutes using the GT Media TSoHTTP websocket... We thank Harmonic folk for sending us this unit, gratis, and appreciate their support of our project!
For stats nerds, what the ProView thinks about the NASA Galaxy 13 downlink parameters:
RF Status: Locked
C/N (dBc): 17.2
Eb/No (dB): 15.79
Link Margin (dB): 10.29
BER: 0E-10
Modulation Standard: DVB-S
Carrier Frequency (GHz): 3.920124
L-Band Frequency (GHz): 1.230124
Frequency Offset (kHz): 124
Spectral Inversion: Inverted
Modulation & FEC: QPSK 3/4
Symbol Rate (Msym/s): 28.070316
UPDATE: 3 Mar 2022, NASA has reverted to standard 8-bit luma+chroma on the UHD satellite feed, after reports of some compatibility issues with 10-bit formats. We are still converting to a 10-bit format for the 30 fps stream to allow for best-case decoder performance and visual quality. Since most folks are using software players on the web, we enjoy broad main10 profile support, in contrast to 'hardware' decoders which often do not. NASA TV folks advised us to keep an eye out for updated and new segments being aired soon. Hopefully more folks who enjoy this stream can send emails to NASA TV folks and thank them for their work on creating and managing good content for the UHD channel. We've also added a handy, 1080/HD scaled flavor of the 30 fps stream, with a handy HTML5 player & Chromecast support. Scroll down for that URL.
