摘要：
A recording device is switched for high-speed reproduction in response to a high-speed reproduction control signal input from an external unit, and a signal read from the recording device is input to a VLD and a formatter. The high-speed reproduction control signal is input to the recording device, to the switch and to the counter. The recording device reproduces a predetermined data and outputs it according to the high-speed reproduction control signal. The VLD no longer effects the variable length encoding of MPEG, and executes the syntax analysis. The counter counts the number of frames being transmitted. Temporal_reference is output depending upon the speed of reproduction indicated by the high-speed reproduction control signal. The header converter rewrites temporal_reference in the picture header in response to temporal_reference output from the counter. It is thus made possible to reproduce the dynamic image at high speeds.
摘要（中）：
响应于从外部单元输入的高速再现控制信号，切换记录装置进行高速再现，并且从记录装置读取的信号被输入到VLD和格式器。 高速再现控制信号被输入到记录装置，交换机和计数器。 记录装置再现预定数据并根据高速再现控制信号将其输出。 VLD不再影响MPEG的可变长度编码，并执行语法分析。 计数器对发送的帧数进行计数。 根据由高速再现控制信号指示的再现速度来输出时间参考。 报头转换器响应于来自计数器的temporal_reference输出重写图片头部中的temporal_reference。 因此，可以高速再现动态图像。
