Stream Data Reception/Reproduction Device and Stream Data Reception/Reproduction Method
First Claim
1. A stream data reception/playback apparatus, comprising:
- a receiving section that receives a packetized stream data;
a receiving buffer that stores frames of the received stream data;
a frame detection section that detects a frame to be played back from a frame group of the stored stream data; and
a playback speed control section that adjusts a playback speed of the stream data when the frame to be played back is not detected in the frame detection section.

Abstract
There is disclosed a stream data reception/reproduction device capable of suppressing deterioration of quality of stream data reproduced even when the stream data is received via an IP network or the like in which the packet arrival timing and the order are not guaranteed. In this device, a reproduction speed control unit (107) sets various conditions in accordance with the value of the synchronization difference reported from a synchronization difference calculation unit (102). Only when the set conditions are satisfied, the speed of reproduction of a frame decompressed and inputted from a decoding unit (105) is adjusted. The reproduction speed control unit (107) interpolates a predetermined amount of sample data into the frame or decimates it from the frame when adjusting the reproduction speed.
