This invention provides the unique and high-throughput architecture for multiple video standards. Particularly, we propose a novel scheme to integrate the standard in-loop filter and the informative post-loop filter. Due to the non-standardization of post filter, it provides high freedom to develop a certain suitable algorithm for the integration with loop-filter. We modify the post filter algorithm to make a compromise between hardware integration complexity and performance loss. Further, we propose a hybrid scheduling to reduce the processing cycles and improve the system throughput. The main idea is that we use four pixel buffers to keep the intermediate pixel value and perform the horizontal and vertical filtering process in one hybrid scheduling flow. In our approach, we reduce processing cycles, and the synthesized gate counts are very small. Meanwhile, the synthesized results also indicate lower cost for hardware.
