MPEG -4 AVC/ <strong>H.264</strong><br />
• Moving Picture Experts Group (MPEG)<br />
formed in 1988<br />
• Focused on creating a simple <strong>and</strong> clean<br />
solution, limiting options <strong>and</strong> features to a<br />
minimum for video <strong>and</strong> audio data<br />
• Has seven pr<strong>of</strong>iles each targeted to specific<br />
class <strong>of</strong> application<br />

Pr<strong>of</strong>iles <strong>of</strong> <strong>H.264</strong><br />
• Baseline pr<strong>of</strong>ile<br />
• Extended pr<strong>of</strong>ile<br />
• Main pr<strong>of</strong>ile<br />
• High pr<strong>of</strong>ile<br />
• High 10<br />
• High 4:2:2<br />

• High 4:2:2 predictive
Advantages <strong>of</strong> <strong>H.264</strong><br />
• Up to 50% in bit rate savings[2]<br />
• High quality video<br />
• Error resilience<br />
• Network friendliness<br />
• Wide area <strong>of</strong> applications<br />

<strong>AVS</strong> <strong>of</strong> <strong>China</strong><br />
• Developed by a working group <strong>of</strong> <strong>China</strong> named as<br />
“<strong>Audio</strong> video <strong>coding</strong> St<strong>and</strong>ard”[3]<br />
• Originally was developed to replace MPEG 2 format<br />
• Comprises <strong>of</strong> two different parts—<br />
• <strong>AVS</strong> Part 2<br />
High-definition digital video broadcasting <strong>and</strong> high-density<br />
storage media<br />
• <strong>AVS</strong> Part 7<br />
– for low complexity, low resolution mobility applications<br />

<strong>Video</strong> evaluation parameters<br />
• Peak Signal to Noise Ratio (PSNR)<br />
• Mean Square Error (MSE)<br />
• Structural Similarity (SSIM)<br />
10
Performance comparison<br />
parameters<br />
• Simulation with different test sequences<br />
• Bit rate<br />
• Quality<br />
• PSNR<br />
• MSE<br />
• SSIM<br />
• Compression ratio<br />
• Latency<br />
11
Expected outcomes<br />
• Familiarity with st<strong>and</strong>ards<br />
• Simulation <strong>of</strong> the codecs<br />
– Modes <strong>of</strong> Configuration<br />
– Modification <strong>of</strong> Parameters<br />
– Input sequence specifications<br />
– Analyze the codec output<br />
• Identify areas <strong>of</strong> research <strong>and</strong> unexplored problems<br />
• Comparing the outcomes for both systems<br />
12<br />
• Efficient use <strong>of</strong> time <strong>and</strong> re-use <strong>of</strong> knowledge
