This paper presents MPEG(2) decoder post-processing for high definition (HD) flat panel displays. The focus is to design efficient post-processing to reduce blocking and ringing artifacts. Standard deblocking modules are improved to obtain a significant load reduction through a new DCT based control scheme. Standard deringing modules are enhanced through adaptive thresholding to improve the image quality. The schemes are implemented in a MPEG2 decoder for evaluation. The enhanced deblocking filter results in load reduction with an overall reduction in execution time of 41~46% over the basic implementation. The enhanced deringing combined with the deblocking achieves PSNR improvements on average of 0.5 dB over the basic deblocking and deringing on SDTV and HDTV test sequences. The deblocking and deringing models described in the paper are generic and applicable to a wide variety of common (8times8) DCT-block based real-time video schemes.
