A data processing device, includes a bus, a demultiplexer which is coupled to the bus, and which receives a content including video data and audio data. A memory interface which is coupled to the bus, and which is connectable to a memory for temporarily accumulating the video data and the audio data output from the demultiplexer in accordance with a delay amount.

At the time of device starting or channel switching in a content output device, even when buffering of a sufficiently large size is performed in order to address multimedia processing at the time of start of a device and content switching, slow reproduction in which video and audio are synchronized with each other can be performed without keeping a user waiting for a long time, and at an arbitrary reproduction rate with the extent of not giving the user feeling of unnaturalness. The broadcasting reception unit initializes the delay amount to a predetermined start value, then gradually increases it with lapse of time, and stops the increase when the delay amount reaches a predetermined end value. Video and audio are synchronously and slowly reproduced at a reproduction rate decided by an increment per unit time of the delay amount.
