ATSC off air receivers
There is no way to control the PID mapping used in broadcast
programming and we recommend that this equipment NOT be used in
P:I systems unless the broadcast PIDs can be remapped in accordance
with the P:I system requirements.
If an installer does choose to use ATSC off air receivers, broadcast off
air (OA) channels MUST NOT be placed adjacent to P:I protected
channels in the channel map. It does not matter where the physical
channels are located, only whether they are mapped to adjacent
channels in the TV lineup.
A non-P:I, non-off air channel MUST be placed in the channel map
between any broadcast channel and a Pro:Idiom protected channel.
The COM1000 EPG channel makes a good buffer. Analog SMATV
channels can also be used as buffers.
