Patent ID: 8204104

Claim:
A frame rate conversion system comprising: a transmitter and a receiver, the transmitter including a decoding unit configured to decode a compressed video signal encoded by an encoding method using a motion vector, and an encoding unit configured to superimpose reference control information being output from the decoding unit and containing at least a motion vector on a blanking period of the video signal decoded by the decoding unit, and outputting the video signal with the reference control information superimposed by the encoding unit; and the receiver including a decoding unit configured to separate the reference control information from the blanking period of the video signal input from the transmitter, and a frame rate converting unit configured to generate an interpolated frame between frames of the input video signal using the reference control information separated by the decoding unit and to convert the input video signal into the signal of a higher frame rate; wherein the transmitter is an apparatus that outputs a digital video signal conforming to the HDMI (High Definition Multimedia Interface) standard, the encoding unit is provided within the transmitter conforming to the HDMI standard and superimposes the reference control information on a data island period contained in a video frame, the receiver is an apparatus that inputs the digital video signal conforming to the HDMI standard, and the decoding unit in the receiver is provided within the receiver conforming to the HDMI standard and separates the reference control information from the data island period contained in the video frame.
