Title:
同期信号調整装置、同期信号調整方法、映像表示装置、および同期信号発生装置
Document Type and Number:
Japanese Patent JP5616922
Kind Code:
B2
Abstract:
A receiver receives a stream of program data that includes: an image signal including a plurality of frames; a sound signal; and a playback timing signal used for synchronized playback of the image signal and the sound signal. A clock signal generation unit generates a clock signal that is independent of the playback timing signal. A reception timing signal acquisition unit acquires a reception timing signal indicating a receiving time of the program data. An analysis unit analyzes a trend of time-dependent variation in a detected difference between the reception timing signal and the playback timing signal. An adjustment amount generation unit generates an adjustment amount of the clock signal, which causes the difference between the reception timing signal and the playback timing to be constant, by referring to a trend of time-dependent variation analyzed by the analysis unit.
