我们考虑在AWGN信道上传输的3D视频的联合信源-信道编码问题。目标是在两个约束下最小化总比特数，所述总比特数是源比特数和前向纠错比特数之和：主视图的质量和次视图的质量必须大于或等于接收器处的预定阈值。质量是根据整个解码图片组的预期PSNR来衡量的。使用MVC(多视点编码)编码器作为信源编码器，并且使用速率兼容的穿孔Turbo码来保护在噪声信道上编码的3D视频。对于不同的3D视频序列和噪声水平，比较了等差错保护和不等差错保护。
We consider the joint source-channel coding problem of a 3D video transmitted over an AWGN channel. The goal is to minimize the total number of bits, which is the sum of the number of source bits and the number of forward error correction bits, under two constraints: the quality of the primary view and the quality of the secondary view must be greater than or equal to a predetermined threshold at the receiver. The quality is measured in terms of the expected PSNR of an entire decoded group of pictures. A MVC (multiview coding) encoder is used as the source encoder, and rate compatible punctured turbo codes are utilized for protection of the encoded 3D video over the noisy channel. Equal error protection and unequal error protection are compared for various 3D video sequences and noise levels.
