Abstract:
1. A recording and playback apparatus for encoding inputted AV signals to produce coded data and recording the coded data into a randomly accessible recording medium and for playing back and decoding the coded data recorded on the recording medium, comprising: production means for encoding the inputted AV signals using a first coding system to produce first coded data; first recording means for recording the first coded data produced by said production means onto the recording medium; supervision means for supervising a start of a recording process by said first recording means; readout means for reading out the first coded data recorded on the recording medium by said first recording means from the recording medium; conversion means for converting the first coded data read out from the recording medium by said readout means into second coded data corresponding to a second coding system; and second recording means for recording the second coded data converted by said conversion means onto the recording medium; said readout means, conversion means and second recording means being operable to execute the respective processes simultaneously with the recording process by said first recording means, when the start of the recording process by said first recording means is supervised, based on a result of the supervision by said supervision means.
