摘要:
An information playback apparatus has a first acquisition unit (100) configured to acquire contents from an information storage medium, a second acquisition unit (200,211) configured to acquire expansion information from at least one of the information storage medium and an external apparatus via a communication line, a control unit (213) configured to control an acquisition timing of expanded contents information contained in the expansion information on the basis of control information contained in the expansion information, a storage unit (209) configured to store the expanded contents information acquired by the second acquisition unit under the control of the control unit, and a playback unit (101,203,2081,2082) configured to play back the contents, and to play back the expanded contents information, which is acquired at a predetermined timing under the control of the control unit, in synchronism with playback of the contents.
摘要:
A data arranging method for linear PCM data, which allows both low-class and high-class machines to easily perform a reproduction process and can cope with multiple channels. Data having a structure in which each sample data of 20 bits or 24 bits of individual channels is separated to a main word consisting of 16 bits and an extra word consisting of 4 or 8 bits, a collection of 2n-th main words of the individual channels is arranged, a collection of (2n+1)-th main words of the individual channels is then arranged, a collection of 2n-th extra words of the individual channels is then arranged, and a collection of (2n+1)-th extra words of the individual channels is then arranged, is recorded on a recording medium or transferred.

摘要:
Recorded at high density on an optical disk (10) are at least one title set (84, 86) and a volume information file (82). The title set consists (84, 86) of a plurality of files (88) aligned on a boundary between logical sectors. The files (88) store title set management information and data objects to be reproduced. The retrieve data from the optical disk (10), volume file information is read out, thereby acquiring information about the desired title set (84, 86). Then, the information for indicating steps or reproducing the data object and managing the desired title set (84, 86) is acquired. Using the title set management information, data is reproduced from the optical disk (10).
摘要:
This invention forms a menu of video data (88) as the background image of the menu and sub-picture data (90) made of an selection item of the menu, alters highlight information for the selection item of the sub-picture data (90), thereby easily forming various menu. Specifically, a button area for surrounding the selection item and the action item represented by the sub-picture data (90) is provided, and the color and contract of the pattern pixel, background pixel and highlighted pixel as pixel data in the button area are variously altered.
摘要:
An information playback method includes playing back a playback sequence from an information recording medium (1) having a data area (12) including a management area (30) storing management information and an object area (40) storing an object managed by the management information, and a file information area (11) which stores file information corresponding to a recording content of the data area, the object area (40) storing a first object whose playback is managed in logical units as a program chain and a second object whose playback is managed separately from the first object, and the management area (30) storing a playback sequence defining a playback condition of the second object, and playing back at least one of the first and second objects in accordance with the playback sequence.
