Implementation of MPEG-4 video decoding and hardware design based on TMS320C6X DSP

摘要

MPEG-4 is applied to varieties of current and future multimedia applications. The standard not only supports existed frame-based coding standards such as MPEG-1, MPEG-2 or H.263, but also provides content-based representation and flexible toolbox, which lead to MPEG-4 more complicated. This paper first briefly presents the implementation method of the video decoding of MPEG-4 Core Visual Profile, which is a subset of MPEG-4 standard. The Core Visual Profile is quite suitable to streaming video, which will possibly become the hot spot for the development of MPEG-4. Then, the paper proposes a design scheme for the basic hardware structure of the decoding system based on TMS320C6X DSP, and simply analyzes the decoding processing of the system.
