Best relays selection method for error-resilient 3-D video transmission

In color-plus-depth map three-dimensional (3-D) video representation, color and depth map sequences exhibit different error sensitivities to the overall quality. Recognizing that, in this paper, we propose to exploit the relay cooperation benefits to achieve unequal error protection (UEP) for better quality 3-D video transmission. Specifically, we propose to apply the first best amplify-and-forward (AF) relay for transmitting color information with high priority (HP) while the second best AF relay is employed for the depth information with low priority (LP). In particular, we drive closed-form expressions for the bit error probability (BEP). Simulation results of the BEP are presented to demonstrate the proposed UEP scheme in terms of the received 3-D video quality.
