An efficient unequal error protection scheme for 3-D video transmission

In this paper, we propose a new unequal error protection (UEP) scheme, called video packet partitioning for three-dimensional (3-D) video transmission. We also propose a new 3-D video transceiver structure that adopts various UEP schemes based on the packet partitioning. The proposed schemes are applied for the modern 3-D video techniques, i.e., multiview video coding (MVC) and color plus depth (VpD). The schemes for MVC and VpD are tested over cooperative multiinput multi-output-orthogonal division multiplexing (MIMOOFDM) systems. For channel adaptation, we propose switching operations between the proposed schemes to achieve a trade-off between the system complexity and performance. Experimental results show that the proposed schemes significantly achieve high video quality at different signal-to-noise ratios (SNRs) in the wireless channel with the lowest possible bandwidth and system complexity compared to the direct transmission schemes.
