Embodiment 1

[0043] image 3 Shown is a method of generating an adaptive usage context descriptor for a digital item according to a first embodiment of the present invention. image 3 An example describing the preference among usage environment descriptors is shown.

[0044] image 3 It is shown how to adaptively describe various usage environment descriptors so as to provide maximum satisfaction when a user uses multimedia content based on a preference of multiple usage environments. Specifically, image 3 It is shown how to adaptively describe multimedia content (ie, digital items) so as to provide maximum satisfaction when a user uses the multimedia content based on a preference of multiple usage environments.

[0045] Such as image 3 As shown, the "PrecedencePreference" descriptor 301 is described in the adaptation of the digital item. A "PrecedencePreference" descriptor 301 may be used to describe which is considered to be higher (or lower) priority among usage context descripto...

Embodiment 2

[0053] Figure 4 Shown is a method of generating an adaptive usage context descriptor for a digital item according to a second embodiment of the present invention. Figure 4 A description is shown that can be used as an alternative to the next-best strategy in cases where multimedia content and digital items are not suitable for the requirements of the environment descriptor, when using the environment descriptor to describe the adaptation conditions for digital item adaptation.

[0054] Such as Figure 4 As shown, the "AlternativePreference" descriptor 401 is described in the adaptation of the digital item. The "AlternativePreference" descriptor 401 makes it possible to select the next-best policy on the environment descriptor determined by preference. Thus, it provides a basis for optimal use of multimedia content for various users with various requirements in various environments.

[0055] The “AlternativePreference” descriptor 401 is defined by the “TargetPreference” de...

Embodiment 3

[0059] Figure 5 Shown is a method of generating an adaptive usage context descriptor for a digital item according to a third embodiment of the present invention. The method according to the third embodiment of the present invention is characterized in that when the multimedia content is described based on its usage environment descriptor and preference descriptor, "PrecedencePreference" is described in the usage environment descriptor of the digital item and "AlternativePreference" is relatively Expressed by the environment descriptor determined by the aforementioned priority.

[0060] Such as Figure 5 As shown, the "PrecedencePreference" descriptor 501 and the "AlternativePreference" descriptor 502 are described in the adaptation of the digital item. The "PrecedencePreference" descriptor 501 makes it possible to describe the preference using the environment descriptor. Furthermore, the method according to the third embodiment of the present invention may provide alternat...

Abstract

There is provided a method for generating an adaptive usage environment descriptor that considers a usage environment of a digital item. In a description of multimedia contents based on usage environment descriptor and user preference descriptor of the multimedia contents, a 'PrecedencePreference' is defined in respective usage environment descriptor of the digital item, or an 'AlternativePreference' is defined in descriptors of the digital item, or the 'AlternativePreference' and the 'PrecedencePreference' are simultaneously defined in a description of an adaptation condition to adaptively modify and describe the digital item.

Description

technical field [0001] The present invention relates to digital item adaptation, in particular to a method of generating an adaptive usage context descriptor for a digital item. Background technique [0002] In business related to electronic commerce, such as the creation, production, transaction, transmission, management, storage and consumption of multimedia data, there is a demand for flexible, transparent and value-added use of multimedia resources. [0003] More specifically, a declaration model without a processing unit for multimedia data used in electronic commerce is a potential factor that may cause confusion in electronic commerce in consideration of the trend of widespread use of electronic commerce using the Internet. [0004] Considering these problems, the declaration of digital items is stipulated in MPEG-21 of the International Organization for Standardization IOS / IEC SC29 / WG11, fully considering the users of e-commerce business models (users include all sub...
