Abstract:
1. A video and audio synchronizing apparatus for re-synchronizing a reproducing timing of a plurality of content data including at least one of video data and audio data which are packetized and transmitted, comprising: means for judging a re-synchronization timing with respect to re-synchronization of one of the plurality of content data with another of the plurality of content data, based on one of: (a) an audio level of the audio data, (b) a result of comparing an I-frame of the video data to a previous frame, (c) a data transmission status, and (d) an operation by a user; means for determining a delay amount for synchronization at the re-synchronization timing; means for delaying at least the one of the plurality of content data on the basis of the delay amount; and means for analyzing the plurality of content data, wherein, on the basis of an analysis result brought about by the means for analyzing the plurality of content data, the means for judging the resynchronization timing judges, as the re-synchronization timing, a case where a differential between the I-frame of the video data and the previous frame is less than a prescribed value.
