摘要
视频处理系统正在向高清化和智能化发展,多种多样的视频系统应运而生。虽然在不同系统中视频终端的底层硬件和媒体需求有差异,但重点都是关注音视频接口和音视频媒体处理两方面。针对这种情况,提出在视频终端底层抽象出来一组用于媒体资源管理的接口,以方便多媒体产品的扩展。在GM8126开发平台上,采用OV9712图像采集模块,视频终端使用软硬件架构,重点设计了媒体资源管理模块的软件方案。实验结果表明,该系统可以灵活管理视频终端的媒体设备,可应用于各系列视频终端系统的开发。
With the fast development of the video processing system to high-definition and intelligent, variety of video systems emerge as the times require. Although tbe hardware and media requirement of video terminal are different in these systems, but they are all focus on audio and video interface and media processing. In order to solve this problem,the paper proposes a solution that we can abstract a group of media resource management interface from the video terminal bottom which is easy to extend multimedia products. Based on the GM8126 platform and OV9712 image acquisition chip, this paper introduces the software and hardware design of the video terminal in detail, and focuses on the software design of media resource management module. Experimental results show that the design system can manage terminal＇s media device flexibly,and it can be well applied to the development of many other series of video terminal.
