ABSTRACT:
A variable length code recording/playback apparatus, which by encoding intra-frame data and inter-frame data in variable length code, records them as recorded codes on tracks of a prescribed recording medium and playbacks them, includes a data rearranger for recording the data in areas to be played back at least two specific speed mode playbacks on the tracks by rearranging prescribed data out of the data encoded in variable length code, a variable length decoder for playing back the data recorded on the recording medium and decoding them in variable length code, a data rearrangement canceller for controlling and restoring the time series of the output of the variable length decoder to the original data train before the rearrangement, and a decoder for constructing a playback picture from the decoded outputs for several frames in the specific speed mode playback by decoding the output of this data rearrangment canceller.
