Abstract
A technique is used for determining a video format for a video output signal generated by a television receiver. The technique includes acquiring a preferred output format that is one of a plurality of video formats and determining an aspect ratio of a selected television signal having one of a plurality of television signal formats. The video output signal is generated using one of the plurality of video formats having a 4:3 aspect ratio when the selected television signal has a television signal format having a 4:3 aspect ratio and the preferred output format is other than one that has only a 4:3 aspect ratio. A related technique additionally acquires an optional override output format for television signals having an aspect ratio of 4:3 that is used to determine when to use the stated the stated video format to generate the video output signal.
