Problems solved by technology

[0004] However, in this patent document, the DVD video title and the HTML content are only displayed in parallel
Therefore, there is a problem that the expressive ability of video images and the like is insufficient
There is also the problem that the security of the distributed information is insufficient and, if the address is already known, the address is easily obtained by an indeterminate number of people
Thus, there is a problem that the security of the distributed information is insufficient, thus making it difficult to provide high value-added information

Embodiment Construction

[0026] An optical disc device and an optical disc handled by the device according to a preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

[0027]

[0028] First, an example of an optical disc handled by the optical disc device according to the present invention will be described below with reference to the accompanying drawings. This disc considers compatibility with existing DVD-Video specifications, and has the following data structure. FIG. 2 shows an example of the data structure of a DVD-Video reproduced in a DVD-Video player, which is the optical disc device shown in FIG. 1, which will be described later. Fig. 2 shows enhanced DVD video disc, wherein, the DVD video content (with MPEG2 program flow) identical data structure with existing DVD video standard is stored in DVD video area, thereby can record enhanced navigation (hereinafter referred to as in another record area) is ENAV), entities in the other...

Abstract

An optical disk apparatus has a control portion for, based on address information and authentication information read out from an optical disk, providing access to a specific server via a communication line, thereby acquiring extensible information, and a reproducing portion for reproducing and outputting the acquired extensible information. In this optical disk apparatus, if an optical disk is not provided, authentication processing cannot be carried out, and extensible information cannot be acquired. Thus, extensible information can be reproduced with security.

Description

technical field [0001] The present invention relates to optical disc devices. More particularly, the present invention relates to an optical disc device and an optical disc device communication method connected to a network content distribution server. Background technique [0002] Recently, "DVD Specifications for Read-Only Disc Part 3: VIDEOSPECIFICATIONS" was issued in August 1996 for the DVD Forum's specifications for reproducing video images and / or sound information recorded on an information recording medium. The specifications include: presentation data in which actual video image and / or sound data are recorded; and navigation data for managing the presentation data. For presentation data, video data, audio data, and sub-picture data are multiplexed according to the specification for a program stream (2048 bytes) defined in MPEG2. In addition, for the navigation data, describe the PGC (ProGram Chain) and the PGC (ProGram Chain) and unit for setting the time configur...
