Key Loss Avoidance Manual
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.
