Understanding DIRECTV SWM Technology
The TV-Hub has a built-in DIRECTV single wire multiswitch (SWM),
allowing you to connect multiple SWM-compatible receivers via a
single coax cable. At startup, the SWM allocates one of eight channels
to each tuner it detects on the cable. Recording devices will consume
more than one channel, as they offer the ability to record on one or
more channels while watching another.
