Abstract

he scalable video coding extension of H.265/High Efficiency Video Coding (HEVC) is capable of supporting diverse video resolutions. Due to the fact that the Enhancement Layer (EL) is encoded and decoded with the aid of the Base Layer (BL), the decodability of ELs is conditioned on that of the BL. Hence the EL frames occasionally have to be discarded as a result of corrupted BL frames. Therefore, potent Unequal Error Protection (UEP) schemes have been conceived for providing a stronger protection to the BL by invoking a lower coding rate based Forward Error Correction (FEC) or a higher transmit power for a specific Multiple-Input Multiple-Output (MIMO) sub-channel. This stronger protection is essential for the BL for the sake of both avoiding the waste of resources caused by the dropped undecodable EL bits and for improving the reconstructed video quality. In this treatise, we propose an adaptive system for transmitting the layered video bit stream over the wireless channel. The proposed system is capable of selecting an appropriate interlayer (IL) operation-aided FEC (IL-FEC) scheme in order to maintain the robustness of the system by comparing the near-instantaneous Signal-to-Noise Ratio (SNR) to pre-recorded reconfiguration thresholds. Our simulation results show that the proposed adaptive system is capable of providing better video quality over a large proportion of the channel Signal-to-Noise Ratio (SNR) range than its corresponding fixed-mode counterparts.
