Abstract
A data reception and playback apparatus that enables reception of data to be played back next to be performed to the fullest extent possible without degrading the playback quality of data being played back, allowing a plurality of data to be played back seamlessly. In this apparatus, a schedule control section decides the pre-read schedule (pre-read amount and pre-read time interval) of media data to be played back next based on a receive buffer decrease speed input from a receive buffer observation processing section, and outputs a data acquisition request command to a data request processing section in accordance with this pre-read schedule. Data request processing section converts the data acquisition request command for AV2 data input from a schedule control section to a data request signal, outputs this signal to a communication processing section, and executes AV2 data small-amount pre-read processing for a server.
