Description
本申请要求于2016年3月29日提交中国专利局、申请号为2016101868805、发明名称为“多屏显示移动终端中多媒体内容的方法、装置及移动终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
本申请涉及多屏幕显示技术领域，尤其涉及多屏显示移动终端中多媒体内容的方法、装置及移动终端。
为了方便用户同时对多个应用(如，游戏、家庭娱乐、工业设计、图形设计和电子表格分析)进行操作，避免在多个应用之间频繁切换，多屏幕显示技术应运而生。其中，多媒体内容输出设备需要通过传输接口将相同的多媒体内容或不同的多媒体内容传输给多个显示设备(如，显示器或电视机)，以便在多个显示设备上实现多屏幕显示。
目前，现有的PC机通常采用视频图形阵列(Video Graphics Array，简称VGA)作为视频信号传输接口，并通过VGA将视频内容传输给多个显示设备。然而，随着移动终端的广泛应用，移动终端能够支持的多媒体内容的清晰度逐渐提高，在很多的实际应用中，用户需要将移动终端作为多媒体内容输出设备，并将移动终端中的多媒体内容通过多屏幕显示技术显示在多台显示设备上。
但是，本申请的发明人在研究中发现，对于移动终端来说，VGA具有自身的不足：第一，VGA只支持模拟的视频信号传输，而不支持数字的视频信号和音频信号传输；第二，由于一个VGA具有15根物理连接线，因此，一个VGA占用空间比较大，这在空间狭窄的移动终端上是不可能实现的，特别是在多屏幕显示方面，需要根据显示设备的数量在移动终端上配置对应数量的多个VGA，这对于移动终端来说更加剧了实现的难度。并且，针对每一个显示设备，都需要在移动终端上为其配置一个显卡，这也增加了硬件资源的消耗。
由此可见，在实现多屏幕显示时，VGA无法适用在移动终端上。目前需要解
决的技术问题是：如何通过多个显示设备显示移动终端上的多媒体内容，即如何在移动终端上实现多屏幕显示。

DisplayPort(DP)接口标准是一种高清数字显示接口标准，可以连接电脑和显示器，也可以连接电脑和家庭影院。DP接口利用了目前最大工作速率为2.5Gbps的电气层，可获取四条通道总共多达21.6Gbps的带宽。取决于用户想要支持的分辨率大小，可以最大限度的减少通道数量。DP接口将在传输视频信号的同时加入对高清音频信号传输的支持，同时支持更高的分频率和刷新率，DP接口旨在作为内部接口选择取代LVDS，并作为外部接口取代DVI/VGA。它采用具有嵌入式时钟，而不是具有独立时钟和数据的传统顺序数据流的基于微封包的架构。除了主要的视频数据，微封包可携带辅助数字音频数据，实现如多显示器和多显示器的独特功能。
本申请的实施例中采用DP接口这一高清接口实现多屏显示功能。实施例一中DP接口设置于移动终端侧，实施例二中DP接口设置于显示设备侧。
