    • 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 prescribed locations of tracks of a recording medium and plays them back, which 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 it in variable length code, a data restorer 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 restorer.
    • 一种可变长度码记录/重放装置,其通过编码可变长度码中的帧内数据和帧间数据,将它们记录在记录介质的轨道的规定位置上,并将其重播,其中包括数据重排器 通过从编码为可变长度码的数据中重新排列规定的数据,在轨道上记录要播放的至少两个特定速度模式播放的区域中的数据;可变长度解码器,用于重放记录在记录介质上的数据和解码 以可变长度码为单位的数据恢复器,用于在重排之前控制和恢复可变长度解码器的输出到原始数据序列的时间序列的数据恢复器,以及用于从解码输出中构建重放图像的解码器, 通过对该数据恢复器的输出进行解码的特定速度模式播放。
