摘要

A video transmitter, a video receiver, a video recorder, a video reproducer, and a video display all having video signal processings such as a frame rate conversion (FRC) enable prevention of degradation of the video image reproduced by a video signal generated by superimposing first and second video signals on each other. The video transmitter (1) includes an editing unit (2) for superimposing first and second video signals on each other according to video combining information, a video encoding section (3) and a video combining information encoding section (4) for encoding the output video signal from the editing unit (2) and video combining information respectively, a multiplexing section (5) for multiplexing the encoded data, and a transmitting section (6) for transmitting the multiplexed data. The video receiver (11) includes a receiving section (12) for receiving the multiplexed data, a multiplexed data demultiplexing section (13) for demultiplexing the multiplexed data into the video data and the video combining information, a video decoding section (14) and a video combining information decoding section (15) for decoding the video data and the video combining information respectively, and a video signal processing section (16) for subjecting the decoded video signal to a predetermined video signal processing. The video signal processing section (16) adequately controls the video signal processing of the portion of the second video signal superimposed on the first video signal by using the video combining information, thereby prevents image degradation of and around the portion of the second video signal caused by the video signal processing, and generates a video with higher quality.
