H.265 (High Efficiency Video Coding)

H.265, also known as HEVC (High Efficiency Video Coding), is the next-generation video compression standard that revolutionized digital video delivery. Developed in 2012 as the successor to H.264, H.265 delivers the same video quality at approximately half the bitrate, making it the ideal choice for 4K, 8K, and high-quality video streaming applications.

Key Features of H.265 Technology

H.265 introduces several advanced features that make it superior to previous codecs:

Superior Compression: Delivers the same quality as H.264 at 50% lower bitrate
4K/8K Support: Native support for resolutions up to 8192 × 4320 pixels
Advanced Prediction: Improved motion compensation and prediction algorithms
Parallel Processing: Enhanced support for multi-core processing
Better Quality: Improved visual quality at all bitrates
Future-Proof: Designed for next-generation video applications

Technical Architecture

The H.265 codec architecture includes several key improvements over H.264:

Coding Tree Units: Flexible block partitioning for better compression
Advanced Motion Prediction: More accurate motion estimation
Sample Adaptive Offset: Improved filtering for better quality
Parallel Processing: Enhanced multi-threading support
