Appeal No. 2001-2119 Application No. 08/826,744 The claimed invention relates to an audio and/or video data recording and reproducing apparatus which receives a multiplexed input data stream having plural channels of at least one of audio and video data, the input data stream being subsequently demultiplexed and recorded. In a reproducing mode, the recorded data is reproduced and multiplexed in a predetermined order to generate an output data stream. In a particular embodiment, the recording structure utilizes a mirror configuration in which plural recording devices record the same audio and/or video data. Representative claim 2 is reproduced as follows: 2. An audio and/or video data recording and reproducing apparatus comprising: a receiving means for receiving an input data stream having a plurality of channels of at least one of audio data and video data being multiplexed in a predetermined order; a demultiplexing means for demultiplexing each one of said plurality of channels from the received input data stream; a plurality of recording means for recording the demultiplexed each one so that random access is possible, wherein one of said plurality of recording means is configured to record exactly one of said plurality of channels; 2Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 NextLast modified: November 3, 2007
