Abstract: According to one embodiment, an audio/video signal transmitting device includes a hot plug detection unit that acquires from a first audio and video reproduction device and a second audio and video reproduction device, formats of audio/video data that can be reproduced by each of the reproduction devices, a setting processing unit that extract a common format of the acquired formats of the audio/video data that can be reproduced by each of the reproduction devices, and an output signal processing unit that supplies the audio/video data to be reproduced to the first and second audio and video reproduction devices in accordance with the extracted common format.

Abstract: The copy-related information of an input video signal is detected and the copy control information of RDI located at the head of each video object unit and the scrambling control information described in the packet header of the video packets in the video object unit to which the RDI belongs are rewritten so as to coordinate the contents of the copy-related information, those of the copy control information and those of the scrambling control information.

Abstract: An erase prohibition setting unit sets erase prohibition in accordance with an instruction. When the range is not set in units of cells of the current cell, the current cell is divided by a cell separator to set a sequence of advanced cells. A reconstruction part reconstructs management information for playing back the advanced cells and current cell, and appends erase prohibition information to the management information for playing back the advanced cells that belong to the range.

Abstract: The aspect ratio information of an input video signal is detected and rewritten in such a way that the contents of the aspect ratio information of RDI located at the head of each video object unit and the contents of the aspect ratio information in the sequence header of the compressed video data in the VOBU to which the RDI belongs are coordinated.

Abstract: When character information is added to a video signal as graphic characters, a graphic controller controls a display time or the information amount of the character information depending on a multiple-times reproduction speed of a recording medium. Further, when closed caption data is superimposed on a predetermined line of the video signal, a video decoder controls the information amount of the closed caption data depending on the multiple-times reproduction speed of the recording medium.
