基于瑞芯微平台的嵌入式流媒体方案的研究与实现

Research and Implementation of Embedded Streaming Media Scheme Based on Rockchip Platform

针对轨道交通车载乘客信息系统中对于视频播放的需求,本文基于瑞芯微电子股份有限公司的RK3568芯片平台,使用RK3568提供的媒体处理软件平台(Media Process Platform,MPP)相关方法,对TS流媒体视频进行硬解码。通过模拟轨道交通列车视频服务器发送测试视频节目,测试显示效果良好,具有长时间运行稳定、CPU占用较低、发热量小等特点,实测达到工程化应用目标,可实现对于轨道交通车载乘客信息系统LCD动态地图、LCD图文显示器等终端设备的控制。

In view of the demand for video playback in the on-board passenger information system system of rail transit, based on the RK3568 chip platform of Rockchip Electronics Co., Ltd., this paper uses the relevant methods of the Media Processing Platform(MPP)provided by RK3568 to hard decode the TS streaming video. We send the test video through the simulated rail transit train video server.The test display effect is good, with long-time stable operation, low CPU occupation with low calorific value and other characteristics.The actual measurement can achieve the engineering application goal. We can realize the control of terminal equipment such as LCD dynamic map and LCD graphic display of on-board passenger information system of rail transit.
