摘　　要：如今,对高分辨率视频会议系统的需求日益高涨。虽然局域网带宽充足,但便携计算机紧张的计算资源却直接影响了视频会议的效果。针对该问题提出自适应模板编码算法TBCA(Template-Based Coding Algorithm),不仅能比传统自适应算法提高10%的计算资源利用率,并将参数调整频率减少到近一半。TBCA已被实现在校园网会议系统中,大幅提高了用户体验。There is a great demand for high resolution local video conference systems. However, although PC is convenient and local access network bandwidth is sufficient, the computational capacity is a big bottleneck in high resolution laptop video conference system. Template- Based Coding Algorithm （TBCA） is proposed,which can improve the utilization of computing resources by 10% and reduce the frequency of adjustment to a half. A high resolution laptop video conference system based on the TBCA is implemented with satisfactory user experiences.
