APPARATUS AND METHOD FOR DIGITAL RECORDING AND REPRODUCING USING MPEG COMPRESSION CODEC

摘要

PURPOSE: A digital recorder/player and its method are provided to be compatible with various multimedia products, to edit as a screen unit and to perform a fast searching function by coding and decoding through compression coding and decoding schemes of MPEG-2(Moving Picture Experts Group). CONSTITUTION: The first decoder(301) supplies coded video data by compressively coding inputted video data as a screen unit. The second decoder(311) supplies coded audio data by coding inputted audio data. The first PES(Packetized Elementary System) packetizer(310) supplies video PES by packetizing the coded video data. The second PES packetizer(312) supplies audio PES by packetizing the coded audio data. A third PES packetizer(313) supplies user PES by packetizing user data. A transmission stream packetizer(314) multiplexes the video PES, the audio PES and the user PES as a transmission stream.
