H.264 was joint development of MPEG and VCEG which aimed at better compression than H.263 and MPEG-4 Part 2. H.264 is also known as ‘Advanced Video Coding (AVC)', ‘MPEG-4 Part 10' and ‘ITU-T Recommendation H.264'. H.264 provides approximately 50-70% more compression than earlier standards.
H.264 introduced following new techniques for better compression.
- Reference pictures can be used in Inter prediction.
- Prediction is formed from a macro block or 4x4 luma blocks.
- Integer IDCT
- Quarter pixel motion compensation
- CAVLC, CABAC
- Bi directional Prediction
- Field Coding
- Weighted Prediction
- Deblocking filter
