ABSTRACT:
An audio/video synchronizing system and a monitor apparatus can provide a set of contents where the images and the sounds of the contents show lip synchronization to the user so that the user may not have any strange and uneasy feeling if only the images are transmitted wirelessly. A contents server outputs sounds of a set of contents at a timing delayed by an initial delay time (1 second) that is greater than the transmission delay time according to the PTS and the DTS defined by the contents server by taking the largest transmission delay into consideration. The monitor corrects the time base of the STC added to the video packets according to the transmission delay time and subsequently outputs the images according to the SCR, the time base of which is corrected, and the PTS and the DTS, for which the initial delay time is defined. With this arrangement, it is possible to compensate the delay of the transmission delay time and display the images at a timing synchronized with the timing of outputting the sounds. Thus, it is possible to realize lip synchronization between the sounds and the images if only the images are transmitted wirelessly.
