Abstract

The coding processing is suspended when at least one of the first to third buffers store(s) therein data of amount exceeding its/their respective maximum amount(s). The coding processing is restarted when at least one of the first to third buffers store(s) therein data of amount below its/their respective reference amount(s) which is/are set to smaller values than the maximum amounts, respectively. This enables prevention of overflow of the first and second buffers. This can also prevent unread data from being overwritten in the first and second buffers, so that generation of not normal multiplexed data can be prevented. Accordingly, the output of erroneous multiplexed data can be prevented.
