Abstract: In a system for recording/playing back video data together with control information, a thumbnail, or thumbnail control information, extracted from a moving picture of a video is used as the control information. The thumbnail control information includes information for generating a thumbnail image which is generated based on the contents of the video data, and information for using the generated thumbnail picture in a menu corresponding to the contents of the video data. The user can create a menu corresponding to the video recorded contents.

Abstract: A digital data output circuit generates video and audio data. An HDMI LSI generates transmission video and audio data by alternately arranging the video data and audio data generated from the digital data output circuit. An LSI control portion outputs a data switching signal which is used to switch the transmission video and audio data. Further, the HDMI LSI selects and transmits one or both of the generated video and audio data in accordance with the data switching signal from the LSI control portion.

Abstract: A recording medium has a management area and a data area. Information pertaining to recording reservation is recorded in the management area so as to be displayable in the form of an image. A recording/playback apparatus for recording and reproducing information with respect to the recording medium reads out information pertaining to recording reservation from the recording medium and executes reservation recording on the basis of the information that is read out.

Abstract: A digital recording/reproducing apparatus uses an information medium for storing audio-visual information corresponding to a plurality of types of audio languages and sound mode information associated with these audio languages. The apparatus is configured to record the audio-visual information on the information medium or to reproduce the audio-visual information from the information medium based on at least one of a plurality of different formats.

Abstract: A DVD recording/reproducing apparatus according to the present invention includes a copy range designator for designating a copy range of data to be copied from a source disc to a dubbing disc, a VOBU fetcher for fetching VOBU according to information designated by the copy range designator, a copy protection information fetcher for fetching copy protection information from control packs in the VOBU fetched by the VOBU fetcher, a copy protection information determiner for determining a type of copy protection type, such as copy-fully-permitted, only-once copy-permitted, or copy-prohibited according to the information from the VOBU fetcher, a copy protection information updater for updating the copy protection information when determined copying of data being permitted, and a disc drive for recording data thus processed into the dubbing disc.

Abstract: A recording device which handles recording reservations includes input device configured to input a video signal, recording device configured to record the video signal, reservation receiving device configured to receive input of recording reservation information, first recording control device configured to make a target video signal be recorded on the basis of the recording reservation and second recording control device configured to stop recording by the first recording control device when a target video signal, which the recording reservation information requests, cannot be obtained.

Abstract: An auto focus apparatus for a camera comprising a group of lenses which include a focus lens and a zoom lens. The auto focus apparatus also comprises a focus detector, a motor and a controller. The focus detector detects whether the camera is in focus or not. The motor drives the focus lens and zoom lens. The controller controls the motor for driving the zoom lens and the focus lens. When the focus detector does not detect a focused image through the focus lens, the zoom lens is then driven to focus the camera. A method of auto focusing comprises the step of driving a focus lens so as to obtain a focusing point. The method of auto focusing also comprises the steps of detecting whether the camera is in focus or not, and driving the zoom lens when a focusing point is not achieved by the focus lens.
