提出了一种新的多描述（MD）编码方法和相应的可实现的L≥2信道的率失真区域。该方案与最近提出的用于条件码本编码的组合消息共享（CMS）方案类似，从码本结构中随机选择码本。该方案有效地对描述的每个子集执行多层随机分组，从而能够利用描述率“子集”的对称性，无论它存在于何处。新方案专门针对传统多层随机分组作为一种极端特例。
This paper proposes a new multiple description (MD) coding method and an associated achievable rate-distortion region for L ≥ 2 channels. The proposed scheme randomly bins codebooks chosen from the codebook structure, similar to that of the recently proposed combinatorial message sharing (CMS) scheme designed for conditional codebook encoding. The proposed scheme effectively performs multilayer random binning for each subset of the description, which hence enables to utilize the symmetry of a “subset” of the description rates wherever it exists. The new scheme specializes in to the conventional multilayer random binning as an extreme special case.
