碩士 === 國立成功大學 === 資訊工程學系碩博士班 === 94 === The technology behind the MPEG-2 and the MPEG-4/XviD shows us some similar skills, including IDCT, de-quantization, variable length coding, motion vector, as well as macro block involving two modes, intra and inter (non-intra). Setting up the correct parameter for each decoding process, the decoder will run the control path and finish decoding process depends on the input bit-stream data after we merge these two decoding functional unit for the largest efficient. In order to prevent decoding process crashing, it must employ some constrained rules and skills, the range of the values after de-quantization, the error detection of the variable length coding and the validation of motion vectors. We implement the error handler reach the goal for decoding overall input bit-stream data and see what it decoded.
