摘要

第三代移动通信系统将提供更先进类型的交互和分发服务，视频是多媒体通信最突出的应用之一。使媒体内容适应不同的网络特性(通信链路和接入终端)，以使视频传输具有可接受的服务质量，是这种设置中最重要的问题之一。在本文中，我们考虑了视频自适应方法之一，即视频转码，并提出了一种新的基于缓冲区的实时视频转码策略。仿真结果表明，该策略在硬转码条件下也具有良好的性能。

Temporal transcoding for mobile video communication

Third generation mobile communication systems will provide more advanced types of interactive and distribution services, and video is one of the most prominent applications for multimedia communications. Adapting the media content to different networks characteristics (communication links and access terminals), in order to enable video delivery with acceptable service quality, is one of the most important problems in this setting. In this paper, we consider one of the video adaptation methods, namely video transcoding, and we present new buffer-based strategies for temporal video transcoding in a real-time context. Simulation results show that our strategies achieve a good performance in hard transcoding conditions also.
