Arm avc new rules
You're referring to the new rules for the Advanced Video Coding (AVC) standard, also known as H.264!
In 2020, the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) published a new version of the H.264 standard, known as H.264/AVC (Advanced Video Coding) Amendment 3. This amendment introduced several new features and improvements to the original H.264 standard.
Here are some of the key new rules and features in H.264/AVC Amendment 3:
- Improved compression efficiency: The new standard includes several new tools to improve compression efficiency, such as:
- Improved intra-prediction modes
- New deblocking filters
- Enhanced entropy coding
- New chroma subsampling modes: The standard now supports two new chroma subsampling modes:
- 4:2:2 (also known as "422") and
- 4:4:4 (also known as "444")
- Support for higher resolutions and frame rates: The new standard supports higher resolutions (up to 8192x4320) and frame rates (up to 120 Hz).
- Improved support for 3D video: The standard now includes new tools to improve the compression of 3D video content, such as:
- Improved depth map coding
- New 3D video syntax
- New error resilience tools: The standard includes new tools to improve error resilience, such as:
- Improved error detection and correction
- New error concealment techniques
- Improved support for multi-threading: The standard now includes new tools to improve multi-threading, such as:
- Improved parallel processing
- New multi-threading syntax
These new rules and features aim to improve the compression efficiency, quality, and flexibility of H.264/AVC, making it an even more widely used and effective video compression standard.
