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. |

1. A method of a processor processing multimedia data by a multimedia framework, which allows a media application to omit checking of a construction of a media graph, the method comprising the steps of:
(a) receiving, by the processor, information on a component and connection information on the component required for the construction of the media graph from the media application; and (b) ensuring, by the processor, that the media graph is constructed according to contents received in the step of (a) and that the multimedia framework is ready to execute a rendering command without checking the construction of the media graph, wherein the component includes a connection denial incapability component which is incapable of denying a connection, and wherein the connection denial incapability component pre-stores alignment unit information on data processible by the connection denial incapability component, and compares, by the processor, the pre-stored alignment unit information with alignment unit information included in a header of the input data, and receives, by the processor, the data when the pre-stored alignment unit information corresponds to the alignment unit information included in the header of the input data, but denies the reception of the data and makes the data flow, by the processor, when the pre-stored alignment unit information does not correspond to the alignment unit information included in the header of the input data. |
