PROBLEM TO BE SOLVED: To display a video obtained from an identical content in identical timing in a plurality of devices.SOLUTION: In a playback device 100.1, a control unit 120 calculates a self device image output processing time after a decoder 140 starts decode processing before a corresponding monitor 200 displays a first frame. The control unit 120 of the playback device 100.1 acquires from a playback device 100.2 a time for processing other device image output after the playback device 100.2 starts decode processing before the corresponding monitor 200 displays the first frame. The control unit 120 calculates a time for adjustment after subtracting, from a maximal processing time, the time for processing the self device image output with the longest time of the other device image output processing time and the self device image output processing time as the maximal time for processing. The control unit 120 of the playback device 100.1 allows the decoder 140 to start decode processing in timing delayed just by the time for adjustment from prescribed timing. |
