ABSTRACT:
A television signal receiving apparatus with a channel tuner, such as a television, VCR, or cable box has circuitry for extracting nonprogram type information such as may be carried in the vertical blanking interval of a broadcast signal. In order to ensure a reliable signal source for the nonprogram type information the apparatus has a controller for setting the channel tuner to the proper channel and selecting the proper signal source to receive the nonprogram type information when the apparatus is not used for receiving regular programming signals selected by the viewer.
