Decode and encode systems and methods

摘要

In a data decoding technique, a system clock is generated on the basis of a time stamp contained in transmission data to be transmitted every packet, and the transmission data are decoded on the basis of the system clock. The transmission data are stored in a buffer memory (41) before a time stamp is extracted, and the packet storage amount of the transmission data stored in the buffer memory (41) is detected by a counter (43) to increase the read-out rate of the transmission data from the buffer memory (41) by a buffer control circuit (55) when the storage amount is larger than a predetermined reference value, and to reduce the read-out rate of the transmission data from the buffer memory (41) when the storage amount is smaller than the predetermined reference value.
