Abstract
An entertainment system, having a capability to playback a stored digital video record that includes frames of video data received from a television broadcast system, approximates ranges of frames in a digital video record that are either commercials or non-commercials. The system also approximates frames that are either a beginning or an ending of a commercial or a non-commercial. The system then associates as a commercial two of the approximated frames that are a beginning or an ending of a commercial or a non-commercial and one or more of the approximated ranges there between until a predetermined percentage of the playback time of the digital video record is taken up by the associated commercials.
