摘要:
A plurality of devices and a device system are disclosed, in which a plurality of input devices (100; 1701, 1704, 1706; 2210; 4700; 5704, 5706) generate an input AV signal, a related device (110; 1702, 1703, 1705; 2220, 2230; 4810; 5702, 5703, 5705) records and reproduces the AV signal, and a display device (120; 1707; 2240, 2250; 4820; 5707) displays the AV signal. The input devices, the related device and the display device are interconnected to configure an AV system having a bus for transmitting or receiving the AV signal and management information. The related device of the AV system includes a recording medium for recording the AV signal, and the input devices transmit to the related device a request to secure a recording area on the recording medium.
摘要:
A computer readable storage medium being capable of recording a large amount of still picture (1) data thereon, allowing users to make a search based on recording times, and reducing the data size of recording time information, a recording apparatus, and a playback apparatus. When recording still pictures on a large-capacity storage medium, management information on recording times becomes so large that it becomes hard for the recording apparatus and the playback apparatus to process. To minimize the amount of data for managing still picture recording times, N (N is an integer equal to or larger than 1.) still pictures are grouped and, for each group, a first still picture recording time (F_RECTM)(7) and a last still picture recording (8) time are recorded as management information.

摘要:
A CD-ROM (4 in Fig. 1) is provided with an area for forming a character/graphic pattern (14). The character/graphic pattern (14) is formed in such a way that data, which generate on the CD-ROM (4) two sorts of pit patterns having average reflectances different from each other to a perceptible extent, are respectively recorded inside and outside the character/graphic pattern (14). Unless an illegal copy disc is produced by duplicating the legal original disc of the CD-ROM (4) at a very high precision, the character/graphic pattern of the copy disc is invisibly deformed by the discrepancy between the arrangements of the pit patterns of the copy disc and the original disc (4).

摘要:
An information recording and control method and apparatus for a recording medium disc having information previously recorded thereon. New information (105) is overwritten or at least a portion of the previously recorded information (103,104) in a recording area of the recording medium disc. Information on the new information is cataloged as control information (101) on the recording medium disc. Residual information which is part of the previously recorded information which is not overwritten by the new information is treated as new information and information on the residual information which is treated as new information is cataloged as control information on the recording medium disc.
