Combined Inter-layer FEC and Hierarchical QAM for Stereoscopic 3D Video Transmission

摘要

We consider an inter-layer FEC (IL-FEC) technique combined with hierarchical QAM for an efficient and reliable transmission of stereoscopic 3D video. The transmit sources are left and right video streams, and one of them is considered a more important stream for guarantee of conventional 2D service. The source node transmits both left and right videos to a destination node by using the IL-FEC and hierarchical 16QAM schemes, in which video peak signal-to-noise ratio (PSNR) performance varies with the hierarchical value (alpha). In this paper, we present the suitable hierarchical values to achieve the target PSNR performances even in low SNR environment. Numerical simulation results show that the proposed system using IL-FEC and hierarchial 16QAM schemes with the suitable alpha value can gain about 7.3-9.3 dB in the average PSNR performance, compared with the system using IL-FEC and conventional 16QAM schemes.
