多媒体通信技术是基础性的信息技术，随着移动互联网的发展和普及，视频点播、视频直播、视频电话、视频会议等多媒体应用已经进入人们的日常生活。多媒体由音频、视频、图像、图形等来自多个信号源、多种不同类型和多种格式的数据组成。多媒体通信系统致力于在各类网络和应用环境下，高效可靠地传送多媒体数据，为用户提供高用户体验的多媒体视听服务，最总实现5A级的服务，即任意用户在任意时间可以通过任意终端、任意网络，访问任何多媒体内容。本课程围绕多媒体通信系统的设计和实现，将多媒体信号处理、通信原理和计算机网络有机结合，从基本知识(概念和背景)、关键技术(音视频编码、文件格式及容器、传输编程与通讯协议、服务质量/体验质量、安全等)和典型应用系统(流媒体、内容生产)等方面进行系统性地讲解，主要教学内容覆盖：音视频信号处理和编解码、多媒体容器格式和传输协议、多媒体系统框架和标准规范、代表性多媒体通信系统的设计与实现，如互联网视频直播、WebRTC视频通话、云化媒体生产等。特别地，课程强调动手能力和实践环节，将以开源软件和开放标准为基础，指导学生构建实际的多媒体通信系统原型，使得所学知识能够有效地应用于实际系统设计中。

Multimedia communication technology is the foundation of information technology. With the development of mobile Internet and the popularity of multimedia applications, Many applications like video on demand, live streaming, video meeting, and video conference have entered people's daily lives. Multimedia data include audio, video, images, graphics, and others like text or subtitles, is informally considered as the collection of three Ms: multisource, multitype and multiformat data. This course focus on the design and implementation of multimedia communication systems by viewing multimedia signal processing, communication theory and computer networks as a whole. The course will be given step by step from three aspects—basics (concepts and background), enable technologies (include audio/video coding, media format and container, network programming and protocols, QoS/QoE, security, etc.) and representative practical systems (On demand, Live, Interactive). Specifically, the main contents cover the following: audio/video processing and coding, multimedia formats and transport protocols, multimedia framework and standards, design of selectively representative multimedia communication systems like Internet live streaming, and media production over cloud. In particular, the curriculum emphasizes capability of implementing a practical system, help students to make full use of open source software and related open standards to build a prototype multimedia communication system. Thus we hope students can solve practical problems by effectively apply learned knowledge into practice.
