Abstract
A repeater is to be provided between a source device and a sink device and be used in a Lip-sync correction system that transmits a video signal and an audio signal from the source device to the sink device through a HDMI (High Definition Multimedia Interface) transmission path and reproduces the video signal and the audio signal in synchronous with them on the sink device. A communication from the source device to the sink device is defined as a downstream communication, and a communication from the sink device to the source device is defined as a upstream communication. The repeater includes a processor that receives the video signal and the audio signal through the upstream communication and the downstream communication and processes the received video signal and the received audio signal. The processor corrects deviation between the video signal and the audio signal.
