Abstract: The apparatus comprises a first medium, a first recording/reproducing section which can record information on or can reproduce information from the first medium, a second recording/reproducing section which can record information on or can reproduce information from a second medium, and a display signal output section. The apparatus is configured to compose input information, being subjected to recording of the first recording/reproducing processing section, with a reproduction signal, being reproduced by the first recording/reproducing processing section. A result of composition is then output to the display signal output section.

Abstract: When moving pictures are recorded onto an optical disc, not only is text data recorded, but also video-recording start date and time, video-recording end date and time, and source name or channel number serving as primary text data are recorded in alphanumeric characters program by program or cell by cell, a program or a cell being used as a unit of video-recording. Other text data is recorded together with language code. Since the primary text data used to select video data is expressed in alphanumeric characters, a program or cell to be reproduced can be selected, regardless of language, and the text information in the same language as that of the apparatus can be searched for.

Abstract: The erasion level appending range of a file is instructed. According to this instruction, the erasion level is set. When this setting range does not agree with the cell unit of the current cell, the current cell is divided to set a sequence of divided cells. Playback management information of each of the divided cells and current cell is re-created, and erasion level information is appended to playback management information of the divided cell that belongs to the appending range.

Abstract: Upon playback of stream data which is recorded while being appended with time stamp information in units of packets, time management is made using the time stamp information. A video playback time viewed from the user, which may be indicated by I-, B-, and P-picture display times, is different from the time of the time stamp information. For this reason, when time management for the stream data recorded on an information storage medium is made using only the time stamp information, display time control (video playback time control) for the user cannot be accurately done. In this invention, a time relationship table indicating the relationship between the time stamp information recorded in stream data at each I-picture start time position and display time information (PTS or field information) for the user is provided to a portion of management information.

Abstract: An information recording method for recording information on a recording medium, including providing a recording medium having first and second areas, the first area for recording ands reproducing video information, the second area for recording manager information, the manager information being referred to when the video information in the first area is reproduced, the video information including an object file for storing movie and/or still video objects, the manager information including video manager information containing information related to the movie and/or still video objects stored in the object file, the object file including manufacturer's information, the manufacturer's information including manufacturer ID and manufacturer's data, recording the movie and/or still video objects in the object file, recording the video manager information in a third area in the second area, and recording the manufacturer ID and manufacturer's data of a specific manufacturer in a fourth area in the object file.

Abstract: A digital stream signal complying with MPEG-TS is handled as stream object ESOB. The ESOB is recorded in unit of stream object unit ESOBU which includes one or more pack/packet groups. Each pack/packet group has a pack/packet group header at its head position, and stores one or more TS packets after the pack/packet group header.

Abstract: A recordable/reproducible disc has a management area and data area. This data area separately records data of a digital stream signal as one or more objects. The management area is configured to record prescribed management information, which includes object management information and playback order management information. In this configuration, the management area is configured to have marker information independently of the playback order management information.

Each pack/packet group has a pack/packet group header at its head position, and stores one or more TS packets after the pack/packet group header.

Abstract: This invention provides a scheme that can indicate whether or not a plurality of objects have logical continuity when there are plurality of objects recorded by stream recording. Management information of a storage medium includes information indicating continuity between a plurality of objects. When the plurality of objects include leading and trailing objects, and the information indicating continuity includes a continuous recording flag indicating that the trailing and leading objects are continuously recorded.

Abstract: This invention has as its object to be able to support stream recording/playback even when information associated with a reception time of a digital stream signal is not available. Management information of a storage medium is configured to include a flag bit (PATS_SS) indicating validity/invalidity of information (PATS) associated with a reception time of a digital stream signal.

Abstract: A type of a broadcasting system of a digital stream signal to be recorded is checked. When a recorded digital stream signal is present, the broadcasting system of the recorded signal is determined from APP_NAME, and the broadcasting system of the recorded signal is compared with the broadcasting system of a signal to be newly recorded. When these broadcasting systems are matched, an object is added after the recorded ESOB file, and when they are not matched, an ESOB file of the corresponding format is newly created, and the object is recorded in this file. Accordingly, conforming to various broadcasting systems, the invention can provide a mechanism allowing coexistence of recorded contents by various broadcasting systems in one optical disk.
