Decoding method and apparatus

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. <IMAGE>
