摘要
桌面共享作为目前视频交流的一个重要策略广泛应用在视频电话会议通讯方案中。然而高消耗的CPU问题、带宽费用等依然是桌面共享存在的关键问题。基于提高CPU利用率,降低对网络带宽的要求,提升视频通信的质量,本文提出了分布式和集中式结合的混合模式选择策略,并进行了小规模的测试,测试结果显示有效地提高了CPU的利用率,尤其是对网络带宽的要求有效降低,在1 Mb带宽的网络环境下已经可以满足视频会议中桌面共享、应用程序共享的要求并且收到了良好的通信效果。
Desktop sharing is an important strategy in video communication is widely used in video conferencing communication scheme. However, CPU, high bandwidth costs is still the key problem existing desktop sharing. Based on the improved CPU utilization rate, reduce the demand for network bandwidth, improve the quality of video communication, this paper presents a hybrid mode selection strategy combined with the distributed and centralized, and the small scale test, test results show that can effectively improve the utilization rate of CPU, especially the demand for network bandwidth is reduced effectively, in 1Mb the bandwidth of the network environment can satisfy the desktop video conferencing in sharing, application sharing and received better communication effect.
