摘要： An encoding system includes: a plurality of encoding devices that each include an encoding processing unit configured to, at a timing in accordance with a vertical synchronization signal included in a moving picture signal, encode divided image data, wherein one encoding device acts as a single master and the remaining one or more encoding devices act as slave. A main synchronization processing unit configured to be provided in the master, in accordance with the vertical synchronization signal, to transmit a setting signal to the slave to perform setting on the encoding processing unit, so that a start timing of encoding processing by each of the encoding processing units is synchronized in frame image units, and to monitor a synchronization state of the encoding devices based on a state signal representing a state of the encoding processing unit of the ancillary encoding device received from the slave.

摘要： A video/audio synchronization apparatus includes: a decoder configured to decode a frame contained in encoded video data and determine playback time of the frame based on a first clock signal, and decode encoded audio data and determine playback time of an associated audio signal contained in the decoded audio data and to be played back simultaneously with the frame, based on a second clock signal different from the first clock signal; a silent period detector configured to detect a silent period from within the associated audio signal; and an audio timing adjuster configured to reduce a difference between the playback time of the frame and the playback time of the associated audio signal by skipping or repeating a silent period contained within a period of the associated audio signal.
