<p>A system for providing an electronic program guide for both over the air channels and direct broadcast satellite channels includes a VCR (80) with an RF tuner. The RF signal carrying the over the air channels is connected to the RF input (64) of the DBS receiver (50), combined with an RF modulation on channel 3 (or 4) of the DBS channel tuned by the DBS receiver. The combined RF signal is sent to the RF tuner in the VCR, which tunes either channel 3 (or 4) for the DBS channel or the appropriate RF channel for a local over the air channel. The output of the RF tuner is output on the VCR's baseband video output (84) which is connected to a baseband video input (66) on the DBS receiver. This system provides a baseband video signal for both over the air and DBS channels.</p> |
