Abstract: A receiver, such as an HDTV receiver or a Personal Video Recorder (PVR), includes a plurality of tuners. Each tuner is adapted to receive television signals (RF1,RF2) comprising a plurality of channels and communicate the received television signals to a processor. A channel search or autoprogramming routine is disclosed for the detection of channels in the television signal wherein each tuner simultaneously tunes and interrogates a different channel in order to expedite the search. If a signal is not detected on a channel, that channel may be tuned and interrogated by a second tuner. A list is compiled of all the channels that contain a television signal to aid the viewer's selection.

Abstract: A method for processing auxiliary information, such as closed caption or teletext data, in a video system enables an increased number of characters to be displayed per line. According to an exemplary embodiment, a video system (100) includes a tuner (10) operative to receive a video signal including auxiliary information representative of a first number of characters to be displayed per line. A memory (13) is operative to store display list data representative of the received auxiliary information. A controller (11) is operative to retrieve the stored display list data in accordance with a format representative of a second number of characters per line, the second number being less than the first number.
