The growing popularity of mobile devices that feature large colour LCD displays and computationally powerful processors has opened up new opportunities to support data streaming on such devices, from real-time stock quotes with low bit rates, to full-screen high-quality live multimedia. At the same time, the emergence of next-generation 4G wireless communication technologies have made it feasible to stream and playback multimedia content on smart devices with exceptional quality. Imagine the possibility of a sports fan watching a live show of her favorite game on her HTC Touch in the subway; a business analyst receiving real-time streaming quotes of major markets in the world on her Blackberry; or a university student reviewing a video podcast of his lectures using his iPhone in the library. This strategic project seeks to investigate the use of a powerful information theoretic technique, called network coding, in smart devices, with an objective of supporting the next generation of multimedia streaming applications. By taking full advantage of the power of network coding and mitigating its drawbacks, our solutions will be able to deliver information streams to smart devices on time, reliably, and cost-effectively.

以大型彩色液晶显示器和计算能力强大的处理器为特色的移动设备的日益普及，为支持此类设备上的数据流提供了新的机会，从低比特率的实时股票报价到全屏高质量的实时多媒体。与此同时，下一代4G无线通信技术的出现，使得在智能设备上以卓越的质量流式传输和播放多媒体内容成为可能。想象一下，一个体育迷在地铁里用HTC Touch观看她最喜欢的比赛直播的可能性；一位商业分析师在她的黑莓手机上接收世界主要市场的实时流媒体报价；或者一个大学生在图书馆里用iPhone查看他讲课的视频播客。该战略项目旨在研究智能设备中强大的信息理论技术（称为网络编码）的使用，其目标是支持下一代多媒体流应用程序。通过充分利用网络编码的力量并减轻其缺点，我们的解决方案将能够及时、可靠、经济地将信息流传输到智能设备。
