Abstract: Provided is a video/audio playback apparatus and a video/audio playback method in which on receiving an instruction for switching video operation from the video operation switching circuit, a data reading circuit reads a video/audio stream for playing an audio and a video/audio stream for playing a video from a recording medium, and an audio playback circuit reproduces an audio stream separated from the video/audio stream for playing the audio on the basis of time management information embedded in the audio stream and a predetermined reference time, and a video playback circuit reproduces a video stream separated from the video/audio stream for playing the video on the basis of a reference time different from the reference time, and thereby the video can freely played with the audio being normally played.

Abstract: There is provided an information display method and an information display apparatus which detect a motion of a video signal on a display screen on which OSD is displayed, or on a display position of OSD, and changes the state of the OSD or the display screen when there is a motion, whereby the user can view an image with a motion without missing it. A state change amount detector (103) obtains the state change amount in the image displayed on the display screen, and an OSD display state changing unit (107) controls the OSD or the display screen when a state change amount judgement unit (104 ) judges that the state change amount is larger than a predetermined value, whereby overlapping between the image with a motion and the OSD can be prevented.

Abstract: A carrier wave NTSC component or a VSB pilot signal in an IF signal is extracted and judged. Then, on the basis of the judgment result, either of demodulation circuit 13 and 14, which is appropriate for the received broadcast wave is switched. Information of co-broadcasting programs for analog and digital broadcasts are acquired from EPG and memorized. In case of high-speed channel search, analog broadcast is preferentially switched to. In case of co-broadcasting, the analog broadcast program is displayed on the screen at the beginning, and then, the digital broadcast program is switched when the data decoding is completed.

Abstract: An audio-visual recording/playback apparatus having an image pickup unit for capturing video and audio, comprises a compression unit for generating streams from data captured by the image pickup unit, a stream multiplexing unit for multiplexing the streams, and a recording medium on which the streams are recorded. A plurality of streams are generated from a signal captured by the image pickup unit, the plural streams are multiplexed, and the multiplexed stream is recorded. Therefore, when playing the recorded streams using a common player, a viewer can select and play his/her favorite video while continuing playback of audio as it is.

Abstract: As shown in FIG. 1, in an information supply system according to the present invention, a user available area in a built-in recording medium (20) of a recording/reproduction device (10) is used as a contents storage area, so that contents (23a) which can be used by a user are previously recorded in the built-in recording medium (20) when the recording/reproduction device (10) is shipped.
