Multimedia Processing (EE 5359)Project Proposal

Introduction

• A software or a device that enables video compression and decompression is known as a video codec

• The need for video coding standards arose with the increased commercial interest in video communications

• 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

H.264/AVC

• 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

• It is one of 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.

Figure 1: H.264 encoder block diagram [7]

Figure 2: H.264 decoder block diagram [7]

Dirac

• 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.

• The Dirac encoder architecture is as shown in Figure 4. The decoder shown in Figure 5 performs the inverse operations.

AVS China Part 7

• 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 the various profiles of AVS China [5]

• Figures 6 and 7 depict the encoding and decoding architectures of the AVS China codec.

Project Objective

• This project will give an overview of the working, performance and hardware requirements of the three codecs.

• The objective of this project is to analyze the performance of the baseline profiles of the H.264/AVC, Dirac and AVS China Video codecs based on based on various factors like complexity, video quality, bit rates, compression ratio etc.

• Also using sample videos, factors such as PSNR, MSE and SSIM[20] will be derived for two standard formats.
