Abstract :
In this paper, we propose an unequal error protection (UEP) scheme for 3 dimensional (3D) video transmission based on dual AF-DF relay selection protocol. In the proposed scheme, we consider an Amplify-and-Forward (AF) and Decode-and-Forward (DF) cooperative diversity together with the unique properties of video plus depth format to improve 3D transmission over wireless networks. We assume that the relays have the ability to perfect error-checking and the source encoded each frame of 3D video data and classify it into two sequences. The former one is the color sequence which is relayed in high reliable scheme by using perfect DF relay and the latter is depth sequence which is transmitted through AF relay. Results show that the proposed scheme improved the quality of color and depth data by exploiting the relay selection diversity, where the color data has better performance than depth data due to channel reliability.
