Abstract
A video decoder decodes a video signal based on a down conversion function. The video decoder includes a variable length decoder which analyzes a received compressed video stream and extracts motion signals. The analyzed bitstream is converted into a macro block through an inverse quantizer and inverse discrete cosine transform unit in succession, and a motion compensator compensates up-sampled data using the extracted motion signals. Data from the IDCT and data from the motion compensator are added, down-sampled by an adaptive down sampler, and stored in an external memory. For motion compensation, the adaptive up-sampler up samples the data down-sampled at the adaptive down sampler, and the result is provided to the motion compensator.
