C/P
I got some information on the updates nbc is doing this year....
They will be migrating to DVB-S2 with mpeg-4, Dolby-E for all HD and SD feeds
in addition to the c-band sd backup they will be adding a hd backup feed also on cband. at this current time I have no further information on encryption but looks mosty likely they will be using Tandberg Encoders and Decoders which I believe is Trellis 8psk and they will be using Dolby E for audio..
from what I have heard that they will have the top 100 markets switched over before olympics. and the rest of the markets finished before the november elections...
This does not effect any of the DSNG feeds... yet, my guess as more affiliates move to hd news, mpeg4 will be needed to keep up with the capacity
