Abstract: On an optical disk, video object sets (VTST_VOBS) to be reproduced and video title set information (VTSI) serving as management information on the video object sets have been stored. In each video object set (VTST_VOBS), many data cells, each containing video, audio, and sub-picture data, are arranged. Management information on programs chains, which are combinations of programs to be reproduced one after another, has been written in a video title set PGC table (VTS_PGCIT). By referring to the program chain table (VTS_PGCIT) according to the user's input, the playback order of program chains can be changed, enabling the program chains to be reproduced one after another in various modes.

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: A new navigation function is added to a legacy DVD-Video. A player unit plays back recorded contents, that include video contents or AV contents and ENAV contents associated with contents (menu, chapter) of the video contents, from a DVD-Video disc. The video contents of the DVD disc are played back by a video playback engine. The ENAV contents of the DVD disc are played back by an ENAV engine. The ENAV engine controls playback of the ENAV contents and that of the video contents in combination, connection, and/or synchronism with each other according to the played-back contents of the ENAV contents.

Abstract: A sheet finishing apparatus includes first and second conveyance devices for conveying a sheet on a sheet conveyance path, a folding roller device for folding the sheet disposed between the first and second conveyance devices, a folded sheet conveyance path for conveying a folded sheet from the folding roller device, and first and second stopper devices. The first and second stopper devices are respectively disposed downstream and upstream of the sheet conveyance path relative to the folding roller device. The first stopper device positions and aligns a leading edge of the sheet, and guides the sheet conveyed by the first conveyance device to the folding roller device, and the second stopper device positions and aligns a trailing edge of the sheet, and transfers the sheet reversely by the second conveyance device to the folding roller device.

Abstract: Data is recorded in a data area of a disk in a hierarchical structure of program chains, programs, cells and packs, each pack is constructed by a pack header for identifying the pack and a packet having a data stream recorded therein, the packet has a packet header having a stream ID indicating at least a private stream and a sub-stream ID indicating the classification of the private stream described therein, and the classification indicates packet data of Dolby AC3 audio data, packet data of linear audio data, packet data of sub-picture data, or packet data of computer data.

Abstract: There is disclosed a sheet post-processing device which can staple a corner of a sheet bunch conveyed from an image forming device and makes a transverse width of a housing smaller or compact. By disposing a stapler in one end on a sheet processing tray inside a sheet conveying port, the transverse width of the housing is made smaller. For this purpose, the sheet post-processing stores sheets conveyed from the image forming device, matches the sheet bunch stored staples the matched sheet bunch and transfers the matched sheet bunch toward the other end of the sheet bunch and subsequently transfers the stapled sheet bunch toward one end of the sheet bunch.

Abstract: An apparatus includes a playback engine which acquires video/audio contents from a disc, an ENAV engine+Internet connection unit which acquire ENAV contents from the disc or acquire another ENAV contents from a server via a communication line, and a buffer manager. This buffer manager generates timing information upon completion of acquisition of the ENAV contents.

Abstract: An information reproduction method comprises setting an imaginary access unit in a video object in which a still picture is recorded; and managing reproduction by use of the imaginary access unit.

Abstract: An information storage medium records contents and sets for each of the contents a resume permission flag indicating whether or not reproduction resume is permitted by a reproduction resume command or a command of a reproduction device executed based on a user operation.

Abstract: A sheet finishing apparatus includes a first conveyance path connected to a sheet conveyance inlet, a second conveyance path branching from the first conveyance path, a folding roller device disposed in the second Conveyance path for folding the sheet, and a sheet discharge path arranged vertically parallel to the second conveyance path and guiding the folded sheet from the second conveyance path to a sheet conveyance outlet. The second conveyance path includes a first guide path located at a downstream side relative to the folding roller device and guiding a rear side of the sheet, and a second guide path located at an upstream side relative to the folding roller device and guiding a front side of the folded sheet conveyed from the folding roller device. A gate is formed for selectively guiding the folded sheet from the second guide path to the storage device or the sheet discharge path.
