Title
Practical analysis and refinement of a SVC standard scalable vídeo coder
Abstract
Several multimedia applications should run over heterogeneous networks, which are simultaneously composed by devices with different requirements of computational capability and/or communication bandwidth. In order to provide more flexibility modern encoders propose different solutions of scalable video encoding. A scalable video stream is composed by a base layer (responsible by the minimum video requirements) and several enhancement layers (each one enhances the video characteristics). During the last years several specifications of scalable video encoders were introduced. Recently MPEG and ITU-T published SVC standard as the ultimated solution to include scalable funcionality on H.264. However the whole implementation of a SVC encoder demands large computational resources and memory size. The current work presents a detailed analysis of SVC technology and its internal modules. Additionally we propose a refined architecture aiming a tradeoff among low latency time and good encoding efficiency. Comparison results indicate it as a fast and low complexity solution with small video quality loss.
