随着越来越多的移动设备已经具备高清处理能力，它与高清显示设备的互连就成了业界关注的焦点，目前各种接口技术正处于非常激烈的竞争阶段。从实际应用的角度，通过文献研究、专利检索、聚类分析和计算等方法，对HDMI(D Type)、MYDP和MHL 3种主流移动高清接口最新的技术标准进行关键技术指标提取;介绍了这些移动高清接口技术标准;分析了它们所采用的关键技术;同时结合移动设备的特点，从编码传输技术、技术性能、接口物理规范等方面，对比和总结了这些移动高清接口技术的特点，并展望了未来可能的发展趋势。研究结果表明，这3种接口技术在功能特性上各有特色，但从发展现状看来，MYDP和MHL更适用于移动设备与大屏高清显示设备进行互连的应用场景。

As more and more mobile devices with HD capabilities, interconnected with highdefinition display devices became industry focus, these technologies are in intense competition stage. From the perspective of practical application, through several methods including literature research, patent search, clustering analysis and so on, the key technical indicators of these latest mobile HD interface technologies are extracted. Those mobile HD interface technologies and the key technologies of mobile HD interface are introduced. Combined with the characteristics of mobile devices, from the coded transmission technology, technical performance, the interface specifications and other physical features, the features of various technologies are summarized and compared and the development trend is proposed. The results show that these features in the interface technology are different, but MYDP and MHL are more suitable for the development status.
