VIDEO SOUND PROCESSING SYSTEM, VIDEO PROCESSING DEVICE, VOICE PROCESSING DEVICE, OUTPUT DEVICE OF VIDEO SOUND, AND SYNCHRONOUS PROCESSING METHOD FOR VIDEO AND SOUND

摘要

PROBLEM TO BE SOLVED: To surely prevent a deviation between reproduced sound and reproduced video (deviation of lip-sync) in response to a dynamic change of a processing time of a video signal in a device for processing video signal.;SOLUTION: In a video display device 3, a control section 33 specifies the time required until a signal processing is performed and the video is displayed after the video signal is supplied, notifies the delay control information corresponding to the specified time to an upstream equipment through an I/F31 and a control signal line, and performs delay processing of sound signal based on the delay control information in the upstream equipment, every time the control section 33 switches the content of processing of video/sound processing section 32, based on a format of video signal and a set signal processing mode.;COPYRIGHT: (C)2008,JPO&INPIT
