Comparison and Performance Analysis of H 264 AVS China VC 1 and Dirac by Jennie G Abraham EE5359 Multimedia Processing Fall 2009 EE Dept University of Texas at Arlington Disclaimer This is a proposal to be used as a roadmap toward fulfilling the objectives of the project as part of course requirement for EE5359 Multimedia Processing Fall 2009 This powerpoint is not a comprehensive documentation on the subjects and topics mentioned Jennie G Abraham Outline Introduction Multimedia Network Home Media Ecosystem Motivation Project Detail Example project elements Architecture Comparison Design Level Analysis Feature Comparison Algorithmic Comparison Performance Comparison Expected Outcomes Project Timeline References Introduction What Video compression standards aiming at high quality Some standards leave the implementation open and only standardize the syntax and the decoder Optimization beyond the obvious Complexity reduction for implementation Who H 264 ITU T VCEG together with the ISO IEC MPEG AVS China Audio Video Coding Workgroup of China VC 1 developed by Microsoft released by SMPTE Dirac BBC Why Different companies different countries different application royalty fees better algorithms Multimedia Network Home Media Ecosystem A case for seamless integration of video coding standards Motivation Possibly identify new areas of research Exploit redundancies develop cross platform applications etc Familiarize with the codecs H 264 AVS China VC 1 Dirac Availability of the codecs in MPL UTA Lack of comprehensive documentation for these codecs Project Detail The project is detailed as follows Overview of each standard Implementation of each codec Compile and tabulate the developers timeline of release royalty patents Architecture Analysis and Comparison Encoder Decoder Block Diagram Design Level Analysis and Comparison Profiles levels intended applications for each of the profile standard Feauture Analysis and Comparison Integer sizes MB sizes Partition sizes Modes Format Algorithmic Element comparison Prediction Motion Vector Precision Transform In Loop filters Entropy coding And so on Performance Comparison Bit rate PSNR MSE Compression

AVS China Codec Design Level Analysis Example of specific coding parts for H 264 profiles Feature Comparison For example 8x8 4x8 8x4 4x4 adaptive block transform 8x8 and 4x4 adaptive block transform Frequency dependent de quantization matrix Block motion Frequency independent dequantization scaling Long filters for MC 16 bit integer transforms 4 tap bi cubic filters for MC Complex loop filter Bit exact spec Overlap intra filtering Spatial intra prediction Multi picture arbitrary order referencing Fading prediction Loop filter Relatively simple loop filter Range reduction expansion Resolution reduction expansion Intra PCM H 264 VC 1 Overlap in feature sets is a major reason why many companies are currently integrating both codecs into the same chip Algorithmic Comparison Example Algorithmic Element H 264 MPEG 4 AVC SMPTE VC 1 WMV 9 AVS China Part 2 Dirac Entropy coding CAVLC CABAC Adaptive VLC 2D variable length coding Arithmetic coding Transform integer DCT Hadamard integer DCT DCT Wavelet transform and more of similar comparison Performance Comparison Simulation with different test sequences Bit Rate Quality PSNR MSE SSIM Compression Ratio Complexity Encoding Time Decoding Expected Outcome The different facet of the project is aimed at bringing out these outcomes Familiarity with these standards Simulation of the codecs Modes of Configuration Modification of Parameters Input sequence specifications Analyze the codec output Identify areas of research and unexplored problems Document a resourceful detailed how to manual on each reference codec Create a how to format to draw on for other softwares available in MPL and future Efficient use of time and re use of knowledge Timeline IMPLEMENTATION Project proposal Oct 1 AVS China Implementation by Oct 7
