LIPS: A Lightweight Inter-layer Protection Scheme for Scalable Video Coding

Abstract

Scalable Video Coding (SVC) enables the partition of video data into layers of different priorities for adapting to both the diversities of terminal capabilities and the variation of network transmission mediums. It is more desirable that more important video data can be recovered with higher probabilities. In this paper, we propose a lightweight inter-layer protection scheme for SVC transmission, which enables the data in a higher layer (e.g., an enhancement layer) to enhance the data reconstruction in a lower layer (e.g., a base layer) in the receiver side. In contrast to non-inter-layer protection schemes, the simulation result in a DVB-H broadcast channel shows that the scheme exhibits 1% to 45% enhancement on the reconstruction of the SVC video data in the base layer.
