Abstract

In a multi-media system for transferring and receiving a transport stream (MPEG2-TS) between a receiver and a recording/reproducing device using the IEEE 1394 interface, a program number command of a selected program is transferred from the receiver to the recording/reproducing device during a recording/playback mode, and the recording and playback are controlled by only one input device for the receiver. Therefore, other devices of the multi-media system can be controlled without extra hardware added to the receiver. Further, an on-screen graphic (OSG) is provided by the receiver, resulting in a consistent OSG.
