Receiving device and camera system

摘要

A transmitting device in accordance with the present invention includes an encoding unit that converts an input video signal into encoded data and sends out the encoded data to a transmission line, and a synchronization signal generation unit that generates a synchronization signal SYNC for adjusting the phase of an input video signal on the basis of phase information transmitted through the transmission line, wherein the phase information PHS includes information indicating that a timing of a synchronization signal generated by the synchronization signal generation unit is to be advanced by the time necessary for transmission, and the synchronization signal generation unit generates the synchronization signal SYNC so that an input video signal is advanced by the time necessary for transmission.

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.
