VIDEO SOUND SIGNAL SYNCHRONIZATION METHOD AND ITS DEVICE |
摘要 |
PROBLEM TO BE SOLVED: To synchronize a sound output with a reproduced video image by configuring the device such that the sound output is synchronously with a reproduction output of a moving image packet. SOLUTION: A video transmitter 10 adds a time code to sound data and moving image data respectively and outputs the result to a network 18. A moving image data receiver 22 of a video reproduction terminal equipment 20 receives moving image data and a time code from the network 18 and a sound data receiver 24 receives the sound data and the time code. The received moving image data are fed to a monitor display device 30 via a frame buffer 28 and a video image is displayed on a screen. The receiver 24 stores temporarily the received sound data to sound output buffer 32. A sound output timing adjustment device 26 inserts or deletes a silence period in the sound output buffer 32 so that a corresponding sound signal is outputted from a speaker 34 to a frame for video display according to a time code from receivers 22, 24 and buffer consumed amount information of the sound output buffer 32.
