In this work, we develop an architecture to implement a deblocking filter to improve the quality of video decoded from MPEG. The filter is controlled by the quantization scale parameter, which is derived from the decoded stream based on a novel algorithm. The hardware implementation is targeting an FPGA device similar to those currently used in post-processing units of high end flat panel TV sets...
MPEG coded video may be processed for quality assessment or postprocessed to reduce coding artifacts or transcoded. Utilizing information about the MPEG stream may be useful for these tasks. This paper deals with estimating MPEG parameter information from the decoded video stream without access to the MPEG stream. This may be used in systems and applications where the coded stream is not accessible...
