Open SVC decoder: a flexible SVC library

International audienceThis paper describes the Open SVC Decoder project, an open source library which implements the Scalable Video Coding (SVC) standard, the latest standardized by the Joint Video Team (JVT). This library has been integrated into open source players The Core Pocket Media Player (TCPMP) and mplayer, in order to be deployed over different platforms with different operating systems

A DSP based H.264/SVC decoder for a multimedia terminal

International audienceIn this paper, the implementation of a DSP-based video decoder compliant with the H.264/SVC standard (14496-10 Annex G) is presented. A PC-based decoder implementation has been ported to a commercial DSP. Performance optimizations have been carried out improving the initial version performance about 40% and reaching real time for CIF sequences. Moreover, the performance has been characterized using H.264/SVC sequences with different kinds of scalabilities and different bitrates. This decoder will be the core of a multimedia terminal that will trade off energy against quality of experience

An Overview of the SVC4QoE project

The aim of this paper is to give an overview of the SVC4QoE project which purpose is to use Scalable Video Coding (SVC) to optimize video transmission in terms of Quality of Experience over DVB-T2 channels. The originality of this project is to consider the influence of the whole chain of treatments performed on the video data in terms of user-perceived quality. The encoding process, as well as transmission, decoding and display are included in the optimization process. Particularly, the multi-layer structure of SVC is to be exploited to circumvent alterations of the video related to transmission on error-prone networks. Combining SVC with QoE thus provides a way to reduce network operating costs, while increasing the quality from the user's point of view. Several innovations are also to be mentioned, such as the use of a real-time open-source SVC decoder, evaluation of visual quality through subjective quality assessment tests, transmission and synchronization of SVC layers on the receiver's side, and development of a DVB-T2 Gateway which implements the multi-PLP functional-ity in an SVC context
