Abstract:
A video image transmitting device, a video image receiving device, a video image recording device, a video image reproducing device, and a video image displaying device 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 image transmitting device (1) includes an editing device (2) for superimposing first and second video signals on each other according to video combining information, a video image encoding processing portion (3) and a video image composite information encoding processing portion (4) for encoding the output video signal from the editing device (2) and video combining information respectively, a multiplexing processing portion (5) for multiplexing the encoded data, and a transmitting portion (6) for transmitting the multiplexed data. The video image receiving device (11) includes a receiving portion (12) for receiving the multiplexed data, a multiplexed data separating processing portion (13) for separating the multiplexed data into the video data and the video image decoding processing portion (14) and a video image composite information decoding processing portion (15) for decoding the video data and the video combining information respectively, and a video image signal processing portion (16) for subjecting the decoded video signal to a predetermined video signal processing. The video image signal processing portion (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.
