摘要

我们提出使用紧框架展开广义多重描述编码。这种方法在概念上与使用块信道代码非常相似，除了它是在量化之前对连续值数据进行的。给出了畸变分析的示意图。

Multiple description transform coding: robustness to erasures using tight frame expansions

We propose the use of a tight frame expansion for generalized multiple description coding. This method is conceptually very similar to using a block channel code, except it is done on continuous-valued data prior to quantization. A sketch of the distortion analysis is given.
