摘　　要：随着4G通信大规模应用以及多媒体压缩技术的发展,视频传输转向无线化、高清化。为了解决3G无线视频监控系统在带宽和传输速度局限性,提出了一种基于Davinci技术的4G无线通信技术视频传输的实现方法。系统硬件设计采用TI Davinci技术架构的DM3730 ARM+DSP双核处理器,系统应用软件设计基于开源多媒体框架的Gstreamer技术,主要实现了视频采集、H.264编解码、4G网络传输,Linux和Windows双平台播放等功能。与传统的视频传输系统开发方法相比,该视频传输系统的设计具有开发周期短,系统功耗低,占用宽带小等优点。With the large-scale application of 4G communication technology and the development of multimediacompression technology, the video transmission system turns to be wireless and high-definition （HD）. In order tosolve the limitations of 3G wireless video surveillance system in the aspects of bandwidth and transmission speed.This paper presents a 4G wireless communication video transmission method based on Davinci technology. DM3730ARM＋DSP dual-core processor from Texas Instruments （TI） is used in embedded hardware platform. The serversoftware, which is used to capture video, H.264 CODEC, 4G network transmission and video displaying on Win-dows and Linux platforms, adopts an open source multimedia framework named Gstreamer. Compared with the tra-ditional video transmission system development methodology, the system has some advantages, including short de-velopment cycle, lower power consumption and small load in bandwidth use.
