Problems solved by technology

However, providing individual extended control for each of multiple users sharing a recording medium will inevitably complicate the data format of the recording medium and processing at the device side
The larger the number of users, the more complex they will become, adding a huge burden to the maker

[0074] Next, a first embodiment of the recording medium related to the present invention will be described. The recording medium related to this embodiment is a rewritable DVD (hereinafter referred to as "DVD") on which moving image data can be recorded in accordance with the DVD-Video recording standard. figure 1 A DVD 1 and a recording device 100 related to this embodiment are shown. The recording device 100 encodes the broadcast content of the broadcast signal received through the terrestrial antenna 101 and the parabolic antenna 102, and writes the encoded broadcast content to the DVD1. DVD1 is a multi-user compatible DVD shared by two users (User A and User B) shown in the figure.

[0075] The DVD 1 has a layer structure 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 device 100 .

[0113] The present embodiment relates to the recording apparatus 100 for recording the TS-VOB related to the first embodiment. The recording apparatus 100 mainly executes the recording process of TS-VOB, but may also execute the playback process of TS-VOB. In this way, the recording device 100 is a hybrid type having both the functions of a recording device and the functions of a playback device. FIG. 13 shows the internal structure of the recording device 100 . The components shown in the figure can be classified according to their functions into (i) components used in both the recording process and the playback process; (ii) components used only in the recording process; and (iii) components used only in the playback process parts.

[0114] First, components used in both the recording process and the playback process will be described below. Such components include a user interface unit 2 , a drive device 3 , a resident memory 4 and a track buffer 5 .

[0144] This embodiment describes how to designate the position of the extended attribute area on the DVD when the extended attribute area having the attribute "unviewed" is designated by an area identifier set in the PGC information. The access map included in the VOB information associates the playback time period with the size of each VOBU. Therefore, by calculating the sum of the address written in the access map and the playback time period, a VOBU including the start point of the extended attribute area and a VOBU including the end point of the extended attribute area can be identified. When the start point and the end point of the extended attribute area are included in the same unit, the VOBU including the start point and the VOBU including the end point and the VOBU existing between these two VOBUs can be simply read. Here, when the start point and the end point are included in different units, processing becomes complicated. Figure 16A An example is shown in which t...

Abstract

Recording apparatus, recording medium, reproduction appapratus, program and method are disclosed. The recording apparatus 100 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 application of the Chinese patent application entitled "Recording Device, Recording Medium, Playback Device, Program and Method" and application number 028093038 filed on October 30, 2003. technical field [0002] The present invention relates to a recording device for recording a digital stream on a recording medium such as DVD, CD, HD, and semiconductor memory card, and a playback device and recording medium. Background technique [0003] In the course of commercialization of the recording devices described above, maintaining compatibility with digital streams recorded on recording media is an important duty for manufacturers of these recording devices. In order to ensure this compatibility, each manufacturer is actively working on the standardization of the recording format adopted by the recording medium. As a result thereof, various unified standards including the DVD-Video recording standard have been established. [0004] While...
