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: Information about the address of file information in a storage device and file information containing an updated version of the file information is recorded in different areas in the storage device before the file is updated, determination is made as to whether or not the information can be read successfully from the storage device (steps 202 and 204), and based on the determination, determination is made as to whether or not data recovery should be performed and, if data recovery should be performed (steps 201 and 203), data successfully read from the storage device is used to record the data in a sector indicated by the address information (step 205).

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: 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.
