Problems solved by technology

[0005] However, the high-density medium specification specifying the connection between the optical recording / reproducing apparatus and peripheral equipment and the connection between the high-density recording medium and the persistent storage storing the data associated with the high-density recording medium has not yet been perfected, which causes the development of optical Difficulties with recording / reproducing devices
[0006] In addition, there is currently no known preferred method for protecting the contents of high-density recording media and the data provided by association with high-density recording media from outside the recording medium
[0007] In addition, the preferred method of protecting the user's optical recording / reproducing device for storing externally downloaded data is still unknown.
[0008] Therefore, there are many limitations in the development of comprehensive optical recording / reproducing devices based on high-density recording media

Embodiment Construction

[0048] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. First, for convenience of explanation, the present invention takes an optical disk, more specifically "HD-DVD" as an example of a recording medium. However, it is obvious that the technical idea of ​​the present invention is equally applicable to other recording media.

[0049] In the present invention, "persistent storage" is a storage device provided or connected to the optical recording / reproducing device shown in FIG. 1 and is a storage device that permanently stores data. Persistent storage can be divided into two categories. The first type is "necessary persistent storage" such as a flash memory provided in an optical recording / reproducing device. The second type is "additional persistent storage" s...

Abstract

A recording medium, apparatus for reproducing data, method thereof, apparatus for storing data and method thereof are disclosed, in which the recording medium is reproduced using data in a persistent storage data. The present invention includes identifying a provider directory for a content provider of a recording medium in a persistent storage by using provider identification information in configuration file of the recording medium; accessing one or more content directories under the provider directory by an application recorded in the recording medium; reading data in the persistent storage; and reproducing the read data according to an execution of the application.

Description

technical field [0001] The present invention relates to playback using a persistent storage recording medium, and more particularly to a recording medium, an apparatus for reproducing data and a method thereof, and an apparatus for storing data and a method thereof. Background technique [0002] In general, optical discs capable of recording large-scale data have been widely used as recording media. Recently, new high-density recording media, such as Blu-ray Disc (abbreviated as BD hereinafter) or HD-DVD (High-Definition Digital Versatile Disc), have been developed to store high-quality video data and high-quality audio data for a long time. [0003] The development of high-density recording media enables network connection with the external environment of the recording medium, and realizes a combined reproduction function between data stored in the recording medium and data stored outside the recording medium. Additionally, this development enables data with user interacti...
