Abstract
A transport stream for conveying a program for a particular channel includes an auxiliary channel, which conveys multiple lower resolution programs associated with other channels. When a receiver has difficulty receiving a particular channel due to the geographical location of the receiver, the receiver tunes to a stronger signal associated with another channel and recovers a lower resolution version of the desired program from the auxiliary channel conveyed therein.
