AbstractA television receiver system having secondary picture display capability (such as PIP or POP) includes two tuners and signal processing arrangements, and circuitry for receiving a transmitted channel guide. In response to a "BROWSE" command, the receiver maintains the currently-tuned first channel as the source for the main picture, displays text related to a television show on a second channel, activates the secondary picture display circuitry, and tunes the second tuner to the second channel. In this way, the viewer can simultaneously get the benefit of both a text description of the television show on the second channel and view a secondary image of the television show on the second channel, without tuning away from the first channel supplying the main picture.
