US 6,285,408 B1 · Digital audio/video system and method integrates the operations of several digital devices into one simplified system

Abstract

A digital audio/video system and method is disclosed. The digital audio/video system of the present invention integrates the operations of several digital devices into one simplified system by eliminating duplicative elements required in each digital device. The combination of operations allowed by the digital audio/video system and device generally includes simultaneously viewing two TV programs, viewing one TV program while recording the other TV program, simultaneously viewing two TV programs while recording one program, viewing one TV program and another program received from a storage device such as a video tape or a DVD disc, or viewing two programs received from a storage device.

Dependent claims

A digital audio/video system comprising:

a signal reception unit receiving and processing TV signals and signals from a storage unit, said signal reception unit outputting data streams;
a transport demux unit selecting data streams from the signal reception unit and outputting video streams and audio streams, based upon a function selected by a user;
a display unit decoding the video streams from the transport demux unit into one of either a HD class image or a SD class image, and displaying either the HD class image or both the HD class image and the SD class image on a display;
and
an audio unit decoding the audio streams from the transport demux unit and playing the decoded audio streams through an output terminal.
