Abstract: PURPOSE: A low complexity variable order short-term predictor for forming an MPEG-4 ALS VLSI is provided to reduce complexity when MPEG-4 ALS hardware is formed. CONSTITUTION: A pre-determining block(110) generates a modified prediction order in response to an inputted prediction order value. A loop controller(120) determines the numbers of repetition and flag signals in response to the modified prediction order value. An FIR(Finite Impulse Response) filter(160) receives a sampled signal. A pipeline stall is applied to the FIR filter according to radix-2 algorithm. The FIR filter filters the sampled signal. An output block(180) adds a determined result of the loop controller to a filtered output result of the FIR filter.

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.
