摘要：

This paper introduces the virtual collaboration environment and discusses the problems encountered in wireless video transmissions of the participating users. Different schemes are proposed and evaluated to address various problems encountered in the wireless access links of the virtual collaboration system for enhancing the perceived visual quality. The schemes include radio network resource optimization, optimal joint source and channel rate allocation and error resilience enhancement using SVC-MDC. These schemes have been shown to offer a strong potential to be incorporated in a virtual collaboration system for quality enhancement.
