发布时间：2018-07-26 07:59
【摘要】：随着计算机、通信技术的革命性进步和发展,手机不仅仅用来传递语音,而且可以传递文字短信、多媒体彩信、图书、广告等内容,在目前的技术水平下,流畅的视频传输也成为了现实,使手机这一通信工具开始媒体化。这一的背景下,手机电视这一新兴事物应运而生,手机的移动性、便携性、互动性与具有丰富内容的电视内容相结合,将信息和娱乐功能的应用提升到了新的高度。 从业务形态上看,手机电视业务分为点播、直播、下载三种,从实现方式上看,可分为单播方式(可视通话方式、流媒体方式)和广播方式(MBMS、CMMB),由于MBMS缺少终端支撑,CMMB由广电主导,内容数量偏少,且缺少上行链路支持,目前的手机电视业务平台是基于单播方式设计建设的。 为了提高用户体验,后期计划设计建设内容检索与推荐系统,向用户个性化的推荐用户可能喜欢的内容。 本文将从系统架构、相关协议、功能实现、内容检索与推荐等多个方面详细介绍基于单播的手机电视业务平台工作原理。
[Abstract]:With the revolutionary progress and development of computer and communication technology, mobile phones are used not only to transmit voice, but also to transmit text messages, multimedia MMS, books, advertisements, and so on. Smooth video transmission has also become a reality, so that the mobile phone as a communication tool began to media. Under this background, mobile TV, as a new thing, emerges as the times require. Mobile phone mobility, portability, interactivity and rich content of TV content are combined to promote the application of information and entertainment to a new height. From the view of service form, mobile TV service can be divided into three types: on demand, live broadcast and download, and can be divided into unicast mode (visual call mode). Streaming media mode) and broadcast mode (MBMS / CMMB). Due to the lack of terminal support, MBMS is dominated by radio and television, the quantity of content is less, and the uplink support is not enough. The current mobile TV service platform is designed and constructed based on unicast mode. In order to improve the user experience, a content retrieval and recommendation system is designed and constructed in the later stage, and the content that the user may like is recommended to the user individualized. In this paper, the operating principle of mobile TV platform based on unicast is introduced in detail from several aspects, such as system architecture, related protocols, functional implementation, content retrieval and recommendation.
