A Codec For Recording MPEG Transport Streams In The D-VHS System

Abstract

The puper presents a codec fo r recording MPEG Transport Streams' in the D-VHS system. It introduces MPEG Transport Stream recording and outlines the codec functionality. Features which are necessary fo r Transport Stream recording are described, and results highlighted. INTRODUCTION The D-VHS system allows various kinds of digital data to be recorded [l], including MPEG Transport Streams (TS) [2]. In a typical broadcast recording setup, an Integrated Receivcr Decoder (IRD) is connected via an IEEEl394 digital interface to a D-VHS recorder (Fig.1). During recording, the IRD delivers a TS to the recorder. During playback, a TS is transmitted back to the IRD to be decoded and presented on the TV set. The D-VHS recorder can also record and playback analog VHS tapes. satellite or cable broadcast + (e.g. DVB) D-VHS INTEGRATED RECEIVER DECODER D-VHS or VHS tape lEEEl394
