Abstract:
1. A receiving device comprising: a decoding unit that decodes encoded data of video transmitted through a transmission line; a synchronization output unit that synchronizes video data decoded by the decoding unit with a reference synchronization signal, and outputs the video data; a transmission delay information acquisition unit that acquires information related to a delay of the transmission line from the input encoded data and time information; and a synchronization signal transmission unit that determines as a time necessary for transmission a sum of the information related to a delay obtained by the transmission delay information acquisition unit and a delay related to codec processing including decoding processing with the decoding unit, sets the time as a phase difference from the reference synchronization signal, and transmits phase information or time information for generating a synchronization signal that is shifted by the time of the phase difference, through the transmission line.
