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
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 Complexity ssim
Test Sequences Different test sequences Different formats - QCIF/CIF/SD/HDTV

For example:For example:
Overlap in feature sets is a major reason why many companies
are currently integrating both codecs into the same chip.

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
