摘要

在包损网络中实时视频传输的应用层错误控制问题通常由联合源信道编码(JSCC)来解决。传统的JSCC方法以顺序的方式解决这个问题，其中源编码和信道编码没有完全集成。在本文中，我们提出了一个集成的联合源信道编码(IJSCC)框架，该框架以一种集成的方式共同考虑了错误弹性源编码、信道编码和错误隐藏。通过分析和模拟，我们展示了与顺序JSCC方法相比，所提出的IJSCC方法的优点。

An integrated joint source-channel coding framework for video transmission over packet lossy networks

The problem of application-layer error control for real-time video transmission over packet lossy networks is commonly addressed by joint source-channel coding (JSCC). The traditional JSCC approaches solve this problem in a sequential manner, where source coding and channel coding are not fully integrated. In this paper, we present an integrated joint source-channel coding (IJSCC) framework, where error resilient source coding, channel coding and error concealment are jointly considered in an integrated manner. We show through both analysis and simulations the advantages of the proposed IJSCC approach, in comparison to a sequential JSCC approach.
