【摘要】：随着移动互联网和智能硬件的快速发展,多媒体技术已从早期的独立应用普及到了嵌入式应用中,不管是智能硬件、手机应用或是Web程序中的许多模块都越来越依赖于多媒体技术。传统的多媒体互动工具例如WhatsApp,微信,钉钉等在各自的领域都得到了用户的广泛支持。但是这些客户端工具也存在着不可调和的弊端,例如上述APP针对每个用户都有一套不同的ID、用户之间跨客户端交流困难、难以应对多场景的复杂沟通等。WebRTC (Web Real Time Communication)的出现改变了基于客户端服务的多媒体交互现状。WebRTC是将音频技术、视频技术、图像压缩等技术都植入到浏览器中。本文通过研究WebRTC的整体框架,结合实现WebRTC会话的关键技术,实现了一个针对暂时沟通、易操作、嵌入式的多媒体互动平台。该平台以房间为基本单位、用户免登陆、满足用户多样化的实时交互需求。本文主要的研究内容及工作如下:1、本文对WebRTC整体框架进行了研究,介绍了 WebRTC的起源与发展,分析了不同浏览器内核的实现方式和使用特点,确定了 WebRTC可用于多媒体互动平台的研究价值。2、本文通过对实现WebRTC的协议栈深入研究,由浏览器安全模型和基于WebRTC的应用两个角度探索了多媒体互动平台的安全性和隐私性,设计并实现了加强多媒体互动平台的安全途径。3、本文设计了基于WebRTC多媒体互动平台的架构,包括前后端的技术栈选择,以及房间管理模块、多媒体控制模块、共享白板模块、文件共享模块和屏幕分享模块。4、本文论述了基于WebRTC多媒体互动平台的实现过程,并通过对各个模块的功能、平台运行的性能以及安全性的测试,证明了基于WebRTC的多媒体互动平台的实现价值。
[Abstract]:With the rapid development of mobile Internet and intelligent hardware, multimedia technology has been popularized from early independent applications to embedded applications. Whether it is intelligent hardware, mobile applications or many modules in Web programs are more and more dependent on multimedia technology. Traditional multimedia interactive tools such as WhatsApp, WeChat, nail and so on are in their own However, these client tools also have irreconcilable drawbacks, such as the APP has a different set of ID for each user,.WebRTC (Web Real Time Communication), which is difficult to communicate across clients, and is difficult to cope with complex communication of multiple scenes (Web Real Time Communication). The multimedia interactive status of client service is embedded in the browser, such as audio technology, video technology, image compression and so on. By studying the overall framework of WebRTC and combining the key technologies of realizing WebRTC session, this paper implements a multimedia interactive platform for temporary communication, Yi Cao work and embedded system. This platform is based on the room. The main research content and work of this paper are as follows: 1. 1. This paper studies the whole framework of WebRTC, introduces the origin and development of WebRTC, analyzes the realization formula and use characteristics of different browsers kernel, and determines that WebRTC can be used for multi-media interaction. The research value of the dynamic platform is.2. This article explores the security and privacy of the multimedia interactive platform from two angles of the browser security model and the WebRTC based application, and designs and implements a security approach to strengthen the multimedia interactive platform,.3. This paper designs a multimedia interaction based on WebRTC. This paper designs a multimedia interaction based on WebRTC. The architecture of the platform includes the selection of technical stack in the front and back, and the room management module, the multimedia control module, the shared whiteboard module, the file sharing module and the screen sharing module.4. This paper discusses the implementation process based on the WebRTC multimedia interactive platform, and through the functions of each module, the performance of the platform running and the security measurement. It proves the realization value of multimedia interactive platform based on WebRTC.
