Patent ID: 8104067

Claim:
An apparatus comprising: a receiving section for receiving recorded moving picture data transmitted from a transmitting server over a communication line, said moving picture data having a predetermined playback rate; a demodulating section that demodulates the moving picture data and provides demodulated moving picture data; a second buffer memory for temporarily storing the demodulated moving picture data received by the receiving section, wherein said demodulated moving picture data is read from said second buffer memory at a desired speed; a de-multiplexer that receives the demodulated moving picture data at a constant speed and extracts the demodulated moving picture data required for playback processing from the second buffer memory and provides extracted moving picture data; a first buffer memory for storing the extracted moving picture data, wherein said extracted moving picture data is read from said first buffer memory for playback; a decoder configured for receiving the extracted moving picture data from the first buffer memory and for restoring said extracted moving picture data to a state before compression; an encoder configured for converting the restored extracted moving picture data to an output signal; a base clock used to define a local time limits unit; wherein said local time unit is adjusted to prevent underflows and overflows in both buffers; and wherein said local time unit can be adjusted to differ from a time unit used by the transmitting server; and a micro-processing unit for specifying a speed of playing back the moving picture data based on used space of the second buffer memory, for changing a playback speed of the moving picture data.
