中文摘要：

为了方便前端移动视频的自动制作，该文提出了一种面向移动设备的实时足球视频智能播放方案。该方案能够解决使用传统方法因分辨率降低所导致的精彩细节丢失等问题，从而使移动设备用户即使在低分辨率情况下也能够舒适地实时欣赏足球比赛。与传统的处理足球视频所采用的方法不同的是，该方案采用一种完全基于区域的方法来分析和研究实时足球比赛视频，从而很大程度上降低了运算复杂度，并且在降低对硬件设备要求的同时，还能够达到实时处理的要求。该方案分为镜头分类和感兴趣区域的动态提取和显示两部分。实验结果表明，该方案能够高效而可靠地在移动设备上实时地播放足球比赛。

英文摘要：

In order to facilitate video production of the front end, a smart displaying scheme for real-time soccer video on portable devices was proposed. Using the proposed scheme, which can solve the problem of wonderful specifics loss under the reduced resolution users can appreciate real-time soccer games comfortably under low resolution circumstance of portable devices. Different from typical football processing techniques, the proposed scheme exploits a wholly region-based approach to analyze real-time soccer video, and can reduce the computational complexity substantially and satisfy the real-time processing requirements while loosen the dependency on hardware equipments. The proposed scheme is composed of two stages： shot classification and dynamic extraction and playing of region of interest （ROI）. The experimental results manifest that the scheme is indeed efficient, practical as well as reliable, and can play real-time soccer video smartly on portable devices.
