Embedded Real Time Network Multimedia Data Transmission Method

为提高实时视频数据采集和传输的速率,以现场可编程门阵列(Filed Programmable Gate Array,FPGA)为核心处理器,以Verilog HDL描述电路功能实现对同步动态随机访问存储器(Synchronous Dynamic Random Access Memory,SDRAM)的高速访问,基于典型网络实时传输网络多媒体业务数据。新的视频数据高速实时传输方法充分利用FPGA并行处理的特点,提高视频数据采集和传输速率。实验结果证明了本文方法的有效性。

To improve the speed of data acquisition and real-time video transmission, Filed Programmable Gate Array （FPGA） as the core processor, the Ferilog HDL was used to describe the circuit function realization to realize the high-speed access of Synchronous Dynamic Random Access Memory （SDRAM） based on a typical network real-time transmission network multimedia service data. The new high-speed real-time transmission of video data took full advantage of the characteristics of FPGA parallel processing to improve video data acquisition and transmission rates. The experimental results demonstrate the effectiveness of the method.
