  • Publication number: 20020146239
    Abstract: Entry points are managed so they are easy for users to understand. The data recording apparatus has a receiver unit that receives a stream of encoded digital data; an analyzer that detects change in an attribute of the received stream and that outputs the detection information; a controller that generates management information containing the detection information output by the analyzer and time information indicating detection time of the change as a first entry point; a drive that records the management information and the received stream to a data storage medium; and an input unit that defines a second entry point. This second entry point is set relative to the playback path of the stream and used to access and read from a particular point in the stream. The controller further generates the management information containing the first entry point and the second entry point separately identified.

  • Publication number: 20020141738
    Abstract: A recordable optical disc stores one or more video objects. A video stream, a first audio stream, and a second audio stream which is used for dubbing are multiplexed into each video object. Also, an optical disc recording apparatus generates the second audio stream by an audio stream generating means, and multiplexes the generated second audio stream into each video object together with the video object and the first audio stream by a multiplexing means. The generated video objects are recorded onto the recordable optical disc by a recording means. The optical disc in which such video objects are stored facilitates dubbing.

  • Patent number: 6285825
    Abstract: An optical disc records video objects that are obtained by multiplexing a video stream and an audio stream. The audio stream is an arrangement of a plurality of sets of audio frame data. Each video object unit in a video object is an arrangement of packs that have a different payload. The video stream and audio stream are divided using a predetermined size and the resulting data divisions are arranged into packs. At least one video object unit includes packs where stuffing bytes or a padding packet is arranged with part or all of a set of audio frame data so that the boundary with the next video object unit corresponds to a boundary between a boundary between sets of audio frame data. Since the boundary between video objects is made to match a boundary between sets of audio frame data, partial deletes that are performed with a video object unit as the smallest unit will not result in unnecessary parts of data remaining on the optical disc.
