A system for nonlinear viewing of television show segments is provided by transmitting
a main signal and an ancillary signal. The ancillary signal is a short show segment.
The television receiver system can select either the main signal or the ancillary
signal. The ancillary signal is stored in a small cache memory for later access
in place of the main signal. An icon is generated on the television set to notify
the user of the presence of the ancillary signal.
