Abstract: The present invention relates to a multimedia-data-processing method which enables a media graph to always be constructed in a “connection without negotiation” manner, on the basis of an already known media graph construction, and thus provides a media framework in which procedures for connecting components are minimized, thereby improving the performance of a system and satisfying the requests of an OS platform builder and a media application developer. The multimedia-data-processing method of the present invention is performed by a multimedia framework, and comprises: (a) a step of receiving component information required for the construction of the media graph and component connection information from a media application; and (b) a step of ensuring that the media graph is constructed by the content received in step (a), and that the media graph waits for a rendering command, thereby eliminating the necessity of permitting the media application to check the construction of the media graph.

Abstract: Disclosed is a multimedia data processing method by a framework, in which the framework is capable of directly controlling data input and output of components in a state of the framework being interposed between the components and an application program, thereby reducing the time and effort involved in developing the components or the application program.
