EE 5359 MULTIMEDIA PROCESSING PROJECT PROPOSAL PERFORMANCE ANALYSIS OF AVS M AND ITS APPLICATION IN MOBILE ENVIRONMENT Under the guidance of DR K R RAO DETARTMENT OF ELECTRICAL ENGINEERING UNIVERSITY OF TEXAS AT ARLINGTON VIDUR K VAJANI 1000679332 Email id vidur vajani mavs uta edu Introduction Over the past 20 years analog based communication around the world has been sidetracked by digital communication The modes of digital representation of information such as audio and video signals have undergone much transformation in leaps and bounds Figure shown below explains the evaluation of coding standards Figure 1 History Of Audio Video coding standards 17 AVS China 1 was developed by the AVS workgroup and is currently owned by China This audio video standard was initiated by the Chinese government in order to counter the monopoly of the MPEG standards which were costing it dearly Audio video standard for Mobile AVS M is the seventh part of the most recent video coding standard which is developed by AVS workgroup of China which aims for mobile systems and devices with limited processing and power consumption Figure 2 shows the evaluation of AVS video coding standards Audio video standard for Mobile AVS M is the seventh part of the most recent video coding standard which is developed by AVS workgroup of China which aims for mobile systems and devices with limited processing and power consumption Table 1 AVS profiles and their applications 3 Basic Structure Figure 3 Layered Structure 2 Encoder AVS M encoder is shown in figure 4 Figure 4 AVS M encoder 8 Decoder AVS M decoder is shown in figure 5 Figure 5 AVS M decoder 8 The three main characteristics of AVS china are that 3 It is technically an advanced second generation source coding standard and is totally controlled and formulated by China advanced The standard work group law document is formulated independently independent It has an international opening on its formulation Process opening Project Objective The real time mobile video communication requires the balance between performance and complexity This project provides an insight into the AVS M video standard architecture of AVS M codec features it offers and various data formats it supports A study is done on the key techniques such as transform and quantization intra prediction quarter pixel interpolation motion compensation modes entropy coding and in loop de blocking filter Because the system resource is limited in mobile platform compared with AVS P2 AVS M has lower complexity and is suitable for mobile multimedia applications Major applications of AVS M are given below Jiben Profile Record and local playback on mobile devices Multimedia Message Service MMS Streaming and broadcasting Real time video
