EE 5359 SPRING 2011 PROJECT PROPOSAL IMPLEMENTATION OF H 264 AVC AVS China Part 7 and Dirac VIDEO CODING STANDARDS Sharan K Chandrashekar 1000676767 sharan chandrashekar mavs uta edu Introduction Effective digital representation of image and video has been a subject of overwhelming research over the past 20 years The need for an international image and video coding standards arose with the increased commercial interest in video communications New applications in the field of communication multimedia and broadcasting became possible based on digital video coding technology Video coding standards H 264 AVC Dirac and AVS China are the latest standards adopted by ITU 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 the ISO IEC Moving Picture Experts Group and the ITU T Video Coding Experts Group is the most efficient video compression technique available today The generalized block diagrams of the hybrid encoder and decoder for the H 264 AVC codec are shown in Figures 1 and 2 respectively Figure 1 H 264 encoder block diagram 7 EE 5359 SPRING 2011 Figure 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 2011 The Dirac encoder block diagram is shown in Figure 4 The decoder shown in Figure 5 performs the inverse operations Figure 4 Dirac encoder block diagram 10 Figure 5 Dirac decoder block diagram 2 EE 5359 SPRING 2011 AVS China 6 AVS video codec is developed by the Audio Video Coding Standard Working Group of China AVS China comprises of four different profiles namely Jizhun Jiben Shenzan and Jiaqiang of which the Jiben profile basic profile is defined in AVS Part 7 for mobile applications Key applications Jizhun profile Television broadcasting HDTV etc Jiben profile Mobility applications etc Shenzhan profile Video surveillance etc Jiaqiang profile Multimedia 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 2011 Figure 7 AVS China decoder block diagram 17 Project Objective The objective of this project is to compare the baseline profiles of the H 264 AVC Dirac and AVS China 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 be conducted to derive the PSNR MSE and SSIM 20 values for two standard formats Abbreviations and Acronyms AVC Advanced Video Coding AVS Audio Video Standard CIF Common Intermediate Format HDTV High
