摘要:
An information recording apparatus (SS1) is provided with a signal process device (72). The signal process device divides record information (R) into a plurality of partial record information pieces, and applies a predetermined signal process to each of them to output processed partial record information pieces (Sr, P, 42, 43, 44). The signal process device also generates and outputs search reproduction control information (Snav, 41: NAVI-PACK) on the basis of control information (Si) to control a reproduction of the record information inputted from the external. The search reproduction control information includes time information (50: PCI), which indicates a reproduction time for each of the partial record information pieces. The search reproduction control information also includes search information (51: DSI) to search a record position on the information record medium. The apparatus is further provided with a multiplex device (75, 76) for time-axis-multiplexing the processed partial record information pieces and the search reproduction control information.
摘要:
An information recording medium is recorded with a plurality of data groups, each including at least one of video information and audio information and a reproduction permission level by which a reproduction of at least one of the video information and the audio information is permitted; and a reproduction management information including the reproduction permission range information for prescribing the range of the reproduction permission level for the data group which reproduction is permitted. When the reproduction permission level and the reproduction management information are selected, the range of the reproduction permission level of the data groups which reproduction are permitted is detected on the basis of the reproduction permission level selected. Then, the data group is reproduced when the reproduction permission level of the selected data group is included in the range of the reproduction permission level detected.
摘要:
The record information (42, 43, 44) and the access information (51: DSI) are recorded on a record track (1a) of an information record medium (1: DVD) such that the record information and the access information are divided into a plurality of first data groups (30: VOBU), each of which is a unit able to be accessed by an information reproducing apparatus (S2) and each of which comprises the record information and the access information, and are divided into a plurality of second data groups (20: CELL), each of which is a unit able to be logically divided in the reproduction and each of which comprises a series of the first data groups arranged along the record track among the first data groups. Management information (PGCI) are collectively recorded at one portion of the record track, and comprises: a plurality of time unit address informations (200) each indicating an address of respective one of the first data groups to which the record information in every predetermined time unit belongs; and discontinuity information (201) indicating whether or not two addresses, which are indicated to be apart from each other by one time unit by the time unit address informations, belong to a same one of the second data groups.

An information recording medium includes: a plurality of recorded information pieces being independent of each other; a plurality of individual attribute information pieces each corresponding to each of the recorded information piece and including information relating to attributes of the recorded information piece and functions in reproduction; and an aggregate attribute information piece, recorded at a position read out prior to any other positions on said recording medium, and including at least a part of the individual attribute information piece for all of the recorded information pieces.
摘要:
An information record medium (1: DVD) has a record track recorded with video information (42, 44) and audio information (43) to be reproduced by a reproducing apparatus (S2). The reproducing apparatus is provided with a read device (80), performs a normal reproduction while relatively moving the read device along the record track and performs a special reproduction, such as a search, a scan and the like, by moving the read device across the record track on the basis of access information to access the video and audio informations. The video and audio informations and control information (41, 51: DSI) comprising the access information are recorded on the record track such that the video, audio and control informations are divided into a plurality of first data group (30: VOBU), each of which is a minimum unit able to be physically accessed, and are divided into a plurality of second data groups (20: CELL), each of which is a unit able to be logically divided in the normal and special reproductions and comprises a series of the first data groups arranged along the record track. Management information (11, PGCI) including a plurality of first reproduction prohibit informations (202), each of which indicates a prohibition of the special reproduction of respective one of the second data groups, is collectively recorded at one portion of the record track.
