Abstract:
1. A stream data reception/playback apparatus, comprising: a receiving section that receives packetized stream data; a receiving buffer that stores a frame group of the received stream data; a frame detection section that is configured to detect whether the frame group of the stored data stream includes a frame to be played back; a synchronization difference calculation section that calculates a synchronization difference between an internal clock of a transmitting side and an internal clock of a receiving side from the received data stream; and a playback speed control section that adjusts a playback speed of the stream data when the frame detection section does not detect a frame to be played back and an absolute value of the synchronization difference is equal to or greater than a first threshold value, wherein the first threshold is a positive value corresponding to an amount of sample data to be interpolated or decimated by the playback speed control section.
