I propose FAQ 1 - What is the uplink report?
It is a report of changes in the channel map to satellite transponder. These data are part of the data stream from every transponder, so that receivers can get the latest mapping no matter what channel they're tuned to. Data include channel number, channel name, mpeg-2/4 SD/HD, status such as added, removed, or moved, satellite name and location, transponder number and beam type, and availability.
