The plan is to write some SD cards with different SR and FECs for quick tests on the bench.
Since running WinTV6 with the fix I've not had to edit anything for a long time!
at 500Ks and 7/8 fec the data rate including Transport Stream encapsulation must be 806kbps... not sure it can be done but i admit i have not tried yet!
Picture quality will be horrible with mpeg2, you could use the raspberry pi to stream the camera on udp into digilite to get low bitrate mpeg4.
I will see what 1.133Ms/S looks like when I remember how to set WinTV6 or GBPVR to the correct settings, I know the video bit rate needs to be 1110 for FEC 3/4, also have set the audio as low as it will go. Will also try it with no Audio to see what that looks like.
For SR<1000 H264 is the best option, RP into Digilite modulator works well,( no audio though ) so will be testing that with the set of nyquist filters I have just built.
So many bands to build gear for!
I'll post a separate note for SD card operation at low SR settings.
