Embodiment 1

[0069] In this embodiment, the administrator limits the user's viewing authority by setting constraints on user access and viewing, so as to realize the viewing time control of multi-dimensional digital media files.

[0070] First of all, the method of the present invention means that the teacher can control the students to check the matching answers of the exercise book after two hours through customization.

[0071] The customization process is described as follows:

[0072] First, determine the resource type of the resource (exercise book and the matching answer to the exercise book). According to the requirements, the resource belongs to the resource type of a compound object (resource description type: complex); the description in XrML language is as follows:

[0073]

[0074] Second, for the resource type, set the resource's executable operation permission and the attribute corresponding to the operation permission. It can be seen that the operation permission is asso...

Embodiment 2

[0096]This embodiment represents the control of the display dimension of digital media. The two-dimensional plan view is oriented to users with low authority (such as trial and preview before purchase), and the three-dimensional image can be provided to users with high authority (such as users who have paid);

[0097] The description process of this embodiment is as follows:

[0098] First, determine the resource type of the resource (2D plan and 3D stereogram). According to the requirements, the resource belongs to the type of 3D graphics; the description is as follows:

[0099]

[0100]

[0101] Second, according to the type of the resource, set the executable operation permission of the resource and the corresponding attributes of the operation permission for the resource;

Abstract

The invention relates to a resource use control method and a resource use control device of multi-dimensional digital media. The resource use control method of the multi-dimensional digital media includes judging resource types of resources of the multi-dimensional digital media, conducting permission setting on the resource of the multi-dimensional digital media according to the resource types and conducting use control on the resource of the multi-dimensional digital media according to the permission setting. The permission setting comprises operation permission of the multi-dimensional digital media and attributes that the operation permission corresponds to. The method and the device can describe operation of information in the multi-dimensional digital media and with different particle sizes and safety attributes and constraint conditions, prerequisite conditions, personalized customization and the like of the operation, resolve permission dynamic stretching caused by object extraction, recombination or interaction and permission dynamic adjusting problems caused by personalized customization, greatly improve data processing efficiency and improve use experience of a user.

Description

technical field [0001] The invention relates to the field of multimedia, in particular to a resource usage control method and device for multi-dimensional digital media. Background technique [0002] Authorization and use control descriptions for digital works are usually implemented through a rights description language. Currently there are two types of rights description languages, one based on logic, such as License Script language; the other based on XML (Extensible Markup Language, Extensible Markup Language), such as XrML (Extensible Right Markup Language, Extensible Rights Markup Language) Open Digital Rights Language, Open Digital Rights Language). Among them, the License Script language is based on the multi-set (polymorphic) rewriting and logic programming mechanism, and is divided into two parts: dynamic and static. The terminology and usage conditions for content description are defined as the static part, and the changing context is defined as the dynamic part....
