An H.264/SVC memory architecture supporting spatial and course-grained quality scalabilities

The standardized Scalable Video Coding (SVC) extension of H.264/AVC achieves significant improvements in coding efficiency relative to the scalable profiles of prior video coding standards, but its computational complexity and memory access requirements make the design of a low power hardware architecture a challenging task. This paper presents an SVC decoder architecture supporting spatial and coarse-grained quality scalability. The architecture optimizes the size of the on-chip memory and reduces the power-consuming and time-intensive external memory accesses.
