Abstract
A method and device for receiving and storing an electronic television (TV) program guide. In a satellite, cable or broadcast TV system, electronic TV program guides may be coded into the video signals received by the TV receiver. Many currently available TV receivers also allow users to program a list of 'select-channels.' When the receiver is in its select-channel mode, the receiver only tunes to the channels the user stored in the list of select channels. The present invention limits the memory and processing power required to store an electronic TV program guide by only storing program guide information associated with the channels stored by the user in connection with the select-channels function of the receiver. In receivers having a second tuner, the second tuner may be used to automatically update the stored program guide.
