Patent ID: 7433411

Claim:
A decoding apparatus comprising: an input terminal that receives a compressed input signal including a first compressed video signal, a first compressed audio signal and a data signal; a demultiplexer that separates the data signal from the input signal; a decoder buffer that stores the first compressed video signal and the first compressed audio signal; a video decoder that decodes the first compressed video signal stored in the decoder buffer; an audio decoder that decodes the first compressed audio signal stored in the decoder buffer; a memory that stores the data signal separated by the demultiplexer; a CPU that analyzes the data signal stored in the memory; and a data decoder that decodes the data signal stored in the memory; wherein the CPU allows the data signal analyzed by the CPU to be stored in the decoder buffer for decoding by the video decoder or the audio decoder, when the analyzed data signal includes a second compressed video signal or a second compressed audio signal, and the video decoder or the audio decoder supports the compression method used for the second compressed video signal or the second compressed audio signal included in the data signal.
