Abstract:

The H.264/AVC (Advanced Video Coder) or MPEG-4 part 10, is the current state-of-the-art in video coding, providing the highest compression ratios achievable by an internationally standardized video coder (ISO/IEC and ITU-T). These compression capabilities are achieved by a well refined set of coding tools. However further improvements were required and H.264 has already been revised twice to provide new profiles for fidelity extension and professional applications in 2005 and scalability support (H.264/SVC – Scalable Video Coder) in 2007. A third revision under development by JVT (Joint Video Team) aim to support video sources with multiple views (H.264/MVC – Multi-view Video Coder). This lecture presents an overview of the coding tools used by the H.264/AVC and some algorithmic optimizations developed by the UFRGS (Brazil) team toward hardware architecture development for real-time high-definition encoders and decoders.
