Benefits of technology

[0008]The object of the present invention is to provide a recording apparatus that realizes such extended control that can satisfy preference and convenience for the user side, is while alleviating burdens on the maker side.
[0013]Also, by uniformly specifying a section for a plurality of playback paths, executed control to skip a sexual scene or a violent scene, extended control to skip a CM section, and the like can be uniformly executed at the time of playback for a plurality of users. By doing so, the recording apparatus is not required to store a section individually for each user where extended control is to be executed, and therefore, its processing can be simplified. By appropriately using extended control to be executed individually for one user and extended control to be executed uniformly for a plurality of users, a maker of the recording apparatus can manufacture and commercialize recording apparatuses with higher user needs.

Problems solved by technology

However, such a conventional method of specifying the “point” has a limit on determining the contents of the extended control in detail.
However, such a conventional method of specifying a section fails to indicate whether the extended control is to be provided uniformly for a plurality of users or the extended control is to be provided individually for one user, thereby failing to respond to diversification of extended control along with the multi-user compatibility.

first embodiment

[0075]The following describes a first embodiment to which a recording medium of the present invention relates. The recording medium relating to the present embodiment is a rewritable DVD (hereafter simply, a “DVD”) on which moving picture data can be recorded in compliance with the DVD-Video recording standard. FIG. 1 shows a DVD 1 relating to the present embodiment, and a recording apparatus 100. The recording apparatus 100 encodes broadcast contents of a broadcast signal received via a terrestrial antenna 101 and a parabolic antenna 102, and writes the encoded broadcast contents to the DVD 1. The DVD 1 is a multi-user compatible DVD that is shared by two users (user A and user B) shown in the figure.

[0076]The DVD 1 has a layer hierarchy including a physical layer, a file system layer, an application layer, etc., and data in the form of a digital stream is recorded thereon by the recording apparatus 100.

[0077]FIG. 2 shows a structure (file structure) of the DVD 1 on the file system...

second embodiment

[0113]The present embodiment relates to the recording apparatus 100 for recording a TS-VOB relating to the first embodiment. The recording apparatus 100 mainly executes a recording process of a TS-VOB, but can also execute a playback process of a TS-VOB. As such, the recording apparatus 100 is of a hybrid type having functions of both a recording apparatus and a playback apparatus. FIG. 13 shows an internal structure of the recording apparatus 100. The components shown in the figure are categorized by their functions, into (i) components used both for the recording process and the playback process, (ii) components used only for the recording process, and (iii) components used only for the playback process.

[0114]First, the following describes the components used both for the recording process and the playback process. Such components include a user interface unit 2, a drive device 3, a resident memory 4, and a track buffer 5.

[0115]The user interface unit 2 receives, via a remote cont...

third embodiment

[0143]The present embodiment describes how the location of an extended attribute section can be specified on a DVD, when the extended attribute section having the attribute “unviewed” is specified by a section marker set in PGC information. An access map included in VOB information associates the playback time period and the size of each VOBU. Therefore, by summing up the addresses and playback time periods written in the access map, a VOBU that includes the start point of the extended attribute section and a VOBU that includes the end point of the extended attribute section can be identified. When the start point and the end point of the extended attribute section are included in the same cell, the VOBU including the start point and the VOBU including the end point and VOBUs that exist between these two VOBUs are simply to be read. Here, the processing becomes complicated when the start point and the end point are included in different cells. FIG. 16A shows an example where the sta...

Abstract

A recording apparatus is for a DVD on which a TS-VOB, and pieces of playback path information each showing a playback path of the TS-VOB are recorded. When extended control with various contents can be executed by an apparatus at the time of playback, an extended attribute section in which extended control is valid is specified in accordance with the contents of the extended control. When an extended attribute section is to be uniformly specified for playback paths of the TS-VOB, a section marker for specifying a location of the extended attribute section of the TS-VOB is generated in VOB information. When an extended attribute section is to be individually specified for one playback path, a section marker specifying a location of the extended attribute section of the playback path is generated in PGC information. The generated VOB information and PGC information are written to the DVD.

Description

[0001]This application is a divisional of application Ser. No. 10 / 432,227, which is the National Stage of International Application No. PCT / JP02 / 005412, filed Jun. 3, 2002.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a recording apparatus that records a digital stream onto a recording medium such as a DVD, a CD, an HD, and a semiconductor memory card, and relates to a playback apparatus and a recording medium.[0004]2. Description of the Related Art[0005]In the commercialization of the above recording apparatus, maintaining compatibility with digital streams recorded on recording mediums is the important responsibility for makers of such recording apparatuses. To ensure the compatibility, each maker has been actively engaged in standardization of recording formats employed for the recording mediums. As their achievements, various unified standards including the DVD-Video recording standard have been established.[0006]While the maker...
