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.

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.

An information reproducing apparatus has a read device, is capable of reproducing sub picture information and is also capable of performing a highlight display of the sub picture information. In an information record medium to be reproduced by this reproducing apparatus, at least the sub picture information and reproduction control information to control a reproduction of the sub picture information are recorded on the record track such that the sub picture information and the reproduction control information are divided into a plurality of groups. Each of the groups is a predetermined unit able to be accessed by the information reproducing apparatus, and has a sub picture pack in which the sub picture information is contained and a control pack in which the reproduction control information is contained. The reproduction control information includes (i) highlight display control information prescribing at least one of the highlight display of the sub picture information and an operation control corresponding to the sub picture information and (ii) time management information indicating times to manage a start time and an end time respectively of at least one of an effective time period during which the highlight display is effective and an effective time period during which the operation control is effective.
摘要:
An information recording apparatus (SS1) is provided with a signal process device (72) for applying a predetermined process to record information (R) including video information and other information to be recorded onto an information record medium (1: DVD), to thereby output processed record information (Sr) composed of a plurality of predetermined information units (30: VOBU). The signal process device also generates first recording position information for respective one of the information units. The first recording position information indicates recording positions on the information record medium of the information units corresponding to reproduction times of the record information within a predetermined range before and after the respective one of the information units. The signal process unit further generates second recording position information for respective one of the information units. The second recording position information indicates recording positions of the video information to be reproduced within the predetermined range. The information recording apparatus is also provided with: a multiplex device (75, 76) for multiplexing the processed record information, and the first and second recording position informations by each of the information units.
