摘　　要：针对多通道视频编解码技术实现较困难的问题,提出了把Linux多线程思想引入硬件视频编解码模块,以解决多通道视频编解码问题。结合现代软件工程思想,将编解码软件模块分为Linux内核层、中间件和应用层三个层次,降低了多通道视频编解码的设计难度,具有很强的实用性和扩展性。将该方法应用于可视IP电话终端实践,验证了该方法的可行性。For the difficuhies of multi-channel video encoding and decoding implementation, a solution of applicating muhi-thread of Linux to hardware video encoding and decoding module has been proposed. With reference to Software Engineering, the encoding and decoding software modules have heen divided into Linux kernel layer, middle ware and application-layer to simplify the design with practicality and expandahility. The method has been applied to visual IP telephone terminal, and it＇s availability and feasibility have been verified.
