基于Linux系统的H.264标准的实时视频压缩及传输系统设计

摘要

With the rapid development of computer network media,the research of real-time video compression and trans-mission technology has very important significance. The H.264 real-time video compression and transmission system based on Ubuntu Linux operating system was established. The software and hardware implementation methods of the system,and the de-sign concept of the system structure are introduced in detail. The acquisition and coding module of real-time video is used to de-sign the system,in which the execution codes are adopted to achieve various modules. The results show that the transmission of the system can obtain better image quality and lower transmission delay,which can meet the demands of real-time application.%随着计算机网络媒体的迅猛发展,研究时视频压缩及传输技术具有十分重要的意义.首先建立基于Ubuntu Linux操作系统的H.264实时视频压缩及传输系统,并详细介绍该系统相关软、硬件实现方法和系统结构的设计思想.然后通过实时视频的采集和编码模块设计系统,并采用系统的实现代码具体实现系统的各个模块.结果表明,使用该设计系统进行传输,可以获得较好的图像质量以及较低传输的延时,能满足实时性应用的需求.
