EE 5359 SPRING 2011PROJECT PROPOSALIMPLEMENTATION OF H.264/AVC, AVS China Part 7 and Dirac VIDEO CODINGSTANDARDSSharan K Chandrashekar (1000676767)[email protected] digital representation of image and video has been a subject of overwhelming researchover the past 20 years. The need for an international image and video coding standards arosewith the increased commercial interest in video communications. New applications in the fieldof communication, multimedia and broadcasting became possible based on digital video codingtechnology.Video coding standards H.264/AVC, Dirac and AVS China are the latest standards adopted byITU-T/ISO-IEC, BBC and China standards organization respectively [2].H.264/AVC [2]:H.264/AVC, an open licensed standard, developed as a result of the collaboration between theISO/IEC Moving Picture Experts Group and the ITU-T Video Coding Experts Group is the mostefficient video compression technique available today.The generalized block diagrams of the hybrid encoder and decoder for the H.264/AVC codec areshown in Figures 1 and 2, respectively.Figure 1: H.264 encoder block diagram [7]EE 5359 SPRING 2011Figure 2: H.264 decoder block diagram [7]Dirac [10]:Dirac is a video compression system developed by the British Broadcasting Corporation (BBC) utilizing motion compensation and wavelet transforms. Dirac video codec applications span from mobile and internet to ultra HDTV and film and video production.Figure 3: Original Image (left), Dirac Compressed image (right) [10]EE 5359 SPRING 2011The Dirac encoder block diagram is shown in Figure 4. The decoder shown in Figure 5 performsthe inverse operations.Figure 4: Dirac encoder block diagram [10]Figure 5: Dirac decoder block diagram [2]EE 5359 SPRING 2011AVS China [6]:AVS video codec is developed by the Audio Video Coding Standard Working Group of China. AVSChina comprises of four different profiles namely Jizhun, Jiben, Shenzan and Jiaqiang of whichthe Jiben profile (basic profile) is defined in AVS Part 7 for mobile applications. Key applicationsJizhun profileTelevision broadcasting, HDTV, etc.Jiben profileMobility applications, etc.Shenzhan profileVideo surveillance, etc.Jiaqiang profileMultimedia entertainment, etc.Table 1: Applications of various profiles of AVS China [5]Figures 6 and 7 depict the encoding and decoding architectures of the AVS China codec.Figure 6: AVS China encoder block diagram [5]EE 5359 SPRING 2011Figure 7: AVS China decoder block diagram [17]Project ObjectiveThe objective of this project is to compare the baseline profiles of the H.264/AVC, Dirac and AVSChina Video codecs based on various factors like complexity, video quality, bit rates,compression ratio etc. Also using sample videos, performance analysis of these codecs will beconducted to derive the PSNR, MSE and SSIM [20] values for two standard formats.Abbreviations and Acronyms:AVC: Advanced Video CodingAVS: Audio Video StandardCIF: Common Intermediate FormatHDTV: High-Definition TelevisionIEC: International Electrotechnical CommissionISO: International Organization for StandardizationITU-T: International Telecommunication Union - Telecommunication Standardization sectorMSE: Mean Square ErrorPSNR: Peak Signal to Noise ratioQCIF: Quarter Common Intermediate FormatSMPTE: Society of Motion Picture and Television EngineersSSIM: Structural Similarity MetricEE 5359 SPRING 2011References[1] T.
