ABSTRACT:
A data processor in which input image data is coded by a coder, with the coded image data being stored in a memory. A controller controls a data amount of the coded image data which is output from the coder by comparing a predetermined set value and a data occupation ratio of the memory. The set value is changed in accordance with a transmission rate used when transmitting the coded image data. Audio data may be multiplexed with the output coded image data, with the timing of providing the audio data to the multiplexer being adjusted in accordance with the transmission rate.
