至此，己经按照其功能描述了移动终端。下面，为了简要起见，将描述诸如折叠型、直板型、摆动型、滑动型移动终端等等的各种属性的移动终端中的滑动型移动终端作为示例。因此，本发明能够应用于任何属性的移动终端，并且不限于滑动型移动终端。
如图1中所示的移动终端100可以被构造为利用经由帧或分组发送数据的诸如有线和无线通信系统以及基于卫星的通信系统来操作。
现在将参考图2描述其中根据本发明的移动终端能够操作的通信系统。
这样的通信系统可以使用不同的空中接口和/或物理层。例如，由通信系统使用的空中接口包括例如频分多址(FDMA)、时分多址(TDMA)、码 分多址(CDMA)和通用移动通信系统(UMTS)(特别地，长期演进(LTE))、全球移动通信系统(GSM)等等。作为非限制性示例，下面的描述涉及CDMA通信系统，但是这样的教导同样适用于其它属性的系统。
参考图2，CDMA无线通信系统可以包括多个移动终端100、多个基站(BS)270、基站控制器(BSC)275和移动交换中心(MSC)280。MSC280被构造为与公共电话交换网络(PSTN)290形成接口。MSC280还被构造为与可以经由回程线路耦接到基站270的BSC275形成接口。回程线路可以根据若干己知的接口中的任一种来构造，所述接口包括例如E1/T1、ATM，IP、PPP、帧中继、HDSL、ADSL或xDSL。将理解的是，如图2中所示的系统可以包括多个BSC275。
每个BS270可以服务一个或多个分区(或区域)，由多向天线或指向特定方向的天线覆盖的每个分区放射状地远离BS270。或者，每个分区可以由用于分集接收的两个或更多天线覆盖。每个BS270可以被构造为支持多个频率分配，并且每个频率分配具有特定频谱(例如，1.25MHz,5MHz等等)。
分区与频率分配的交叉可以被称为CDMA信道。BS270也可以被称为基站收发器子系统(BTS)或者其它等效术语。在这样的情况下，术语“基站”可以用于笼统地表示单个BSC275和至少一张BS270。基站也可以被称为“蜂窝站”。或者，特定BS270的各分区可以被称为多个蜂窝站。
如图2中所示，广播发射器(BT)295将广播信号发送给在系统内操作的移动终端100。如图1中所示的广播接收模块111被设置在移动终端100处以接收由BT295发送的广播信号。在图2中，示出了几个全球定位系统(GPS)卫星500。卫星500帮助定位多个移动终端100中的至少一张。
在图2中，描绘了多个卫星500，但是理解的是，可以利用任何数目的卫星获得有用的定位信息。如图1中所示的GPS模块115通常被构造为与卫星500配合以获得想要的定位信息。替代GPS跟踪技术或者在GPS跟踪 技术之外，可以使用可以跟踪移动终端的位置的其它技术。另外，至少一张GPS卫星500可以选择性地或者额外地处理卫星DMB传输。
作为无线通信系统的一个典型操作，BS270接收来自各种移动终端100的反向链路信号。移动终端100通常参与通话、消息收发和其它属性的通信。特定基站270接收的每个反向链路信号被在特定BS270内进行处理。获得的数据被转发给相关的BSC275。BSC提供通话资源分配和包括BS270之间的软切换过程的协调的移动管理功能。BSC275还将接收到的数据路由到MSC280，其提供用于与PSTN290形成接口的额外的路由服务。类似地，PSTN290与MSC280形成接口，MSC与BSC275形成接口，并且BSC275相应地控制BS270以将正向链路信号发送到移动终端100。
基于上述移动终端硬件结构以及通信系统，提出本发明方法各个实施例。
在本发明的各种实施例中：获取用户点击预览图片的第一响应信息，所述第一响应信息是所述用户点击所述预览图片中的第一帧图片所在的区域产生的响应，所述预览图片由所述视频的多帧图片合成；根据响应信息和视频时间点的对应关系，确定所述第一响应信息对应的视频时间点；从所述第一响应信息对应的视频时间点播放所述视频。
实施例一
本发明实施例提供一种视频播放方法，应用于视频播放装置，该视频播放装置可以是智能手机、电脑等终端。如图3所示，该方法包括：
步骤301、获取用户点击预览图片的第一响应信息。
这里，第一响应信息是用户点击预览图片中的第一帧图片所在的区域产生的响应，预览图片由视频的多帧图片合成。
步骤302、根据响应信息和视频时间点的对应关系，确定第一响应信息对应的视频时间点。
步骤303、从第一响应信息对应的视频时间点播放视频。
这样一来，视频播放装置显示预览图片，该预览图片由数据流的多帧图片合成，且点击预览图片上的多帧图片所在的区域都对应该帧图片的视频时间点，因此，用户不仅仅可以根据这些图片更多地了解该视频的内容，选择是否观看，还可以根据图片决定从哪里观看，提高用户体验。
在一实施例中，多帧图片包括原始预览图片和多帧关键帧图片，该方法还可以包括：
按照预设规则，从视频中获取多帧关键帧图片；将关键帧图片和所述原始预览图片合成预览图片。
这里，原始预览图片是现有技术中的预览图片；该原始预览图片可以是视频中的某一帧图片，关键帧与该某一帧图片不能相同；原始预览图片还可以是非视频中的图片，例如海报图片、视频中几帧图片的合成图片等等。
这里，合成预览图片的方法有很多种，例如，将多帧图片顺序排列拼接，将拼接后的图片缩小至预览合成图片的大小。本实施例对此不做限制。
在一实施例中，将原始预览图片设置在合成图片的一个角，关键帧图片环绕该原始预览图片。如图4所示，以7帧关键帧为例，预览图中的原始预览图片位于预览图的右上角，7帧关键帧图片包围原始预览图片，该7帧关键帧图片按从右到左的顺序依次为第1帧关键帧、第2帧关键帧、第3帧关键帧、第4帧关键帧、第5帧关键帧、第6帧关键帧、第7帧关键帧。由于一般情况下，用户观看视频都是从头开始看，因此，将原始预览图片对应到视频的初始时间点。值得说明的是，本实施例还可以将原始预览图片对应到视频已经看到的时间点。
在一实施例中，关键帧图片的帧数是7个。
这里，预设规则可以包括按预设时间间隔来确定多帧关键帧，该预设 时间间隔是多帧关键帧的第i帧关键帧和第i+1帧关键帧图片之间的时间间隔，i是小于多帧关键帧的个数。具体地，预设时间间隔可以根据视频的时间长度按关键帧帧数均分来确定。该视频播放装置打开多媒体视频文件，获取视频时间长度t，该t大于0。并设置获取关键帧图片帧数为x，该x大于0；计算获取的关键帧的视频时间点：0，t/x，2t/x，……，(x-2)t/x，(x-1)t/x。获取各个视频时间点对应的关键帧：i0，i1，i2，……，i(x-2)，i(x-1)。例如，视频时间长度是140分钟，需要取7帧关键帧，若将该时间长度均分，那么，预设时间间隔应该为20分钟，因此，在0到20分钟之间的图片任取一张作为第1帧关键帧，示例地，假设可将10分0秒的图片作为第1帧关键帧，可以将30分0秒的图片作为第2帧关键帧，可以将50分0秒的图片作为第3帧关键帧，可以将70分0秒的图片作为第4帧关键帧，可以将90分0秒的图片作为第5帧关键帧，可以将110分0秒的图片作为第6帧关键帧，可以将130分0秒的图片作为第7帧关键帧。
这里，预设规则还可以包括按照视频的内容进行获取多帧关键帧。例如片头片尾没有什么具体的内容，因此，从略去片头片尾的视频中获取多帧关键帧，从视频中集中出现男女主人公的视频片段中，获取多帧关键帧。因此，本实施例提供的预设规则并不限制具体的规则。
在一实施例中，所述将关键帧图片和原始预览图片合成预览图片之后，该方法还可以包括：
在视频中确定多帧关键帧图片对应的视频时间点；
确定原始预览图片对应的初始时间点；
在预览图片中确定多帧(包含原始预览帧和多帧关键帧)图片所在区域；设置多帧图片所在区域的响应信息；
根据多帧图片所在区域的响应信息、多帧关键帧图片对应的视频时间点和原始预览图片对应的初始时间点，生成响应信息和视频时间点的对应 关系。
具体地，计算并分割预览图片中每一个i0，i1，i2……i(x-2)，i(x-1)关键帧区域。设置i0，i1，i2，……，i(x-2)，i(x-1)关键帧区域的点击响应event0，event1，event2，……，event(x-2)，event(x-1)。设置event0，event1，event2，……，event(x-2)，event(x-1)。对应视频文件执行响应结果result0，result1，result2，……，result(x-2)，result(x-1)。
其中，result0：表示从视频文件0秒位置开始播放。
result1：表示从视频文件t/x秒位置开始播放。
result2：表示从视频文件2t/x秒位置开始播放。
……
result(x-2)：表示从视频文件(x-2)t/x秒位置开始播放。
result(x-1)：表示从视频文件(x-1)t/x秒位置开始播放。
这里，响应信息和视频时间点的对应关系包括：第1帧关键帧图片所在区域的响应信息和第1帧关键帧图片的视频时间点对应；第2帧关键帧图片所在区域的响应信息和第2帧关键帧图片的视频时间点对应；……；最后一帧关键帧图片所在区域的响应信息和最后一帧关键帧图片的视频时间点对应；原始预览图片所在区域的响应信息和视频的初始时间点相对应。一般情况下，初始时间点是0分0秒。
这里，每一帧图片所在的区域对应的响应信息是不同，以区别每一帧图片。
在一实施例中，原始预览图片的区域可以大于多个关键帧图片中任一帧图片的区域。
实施例二
本发明实施例提供一种视频播放方法，应用于移动手机，本实施例中假设关键帧图片的帧数是6，如图5所示，该方法包括：
步骤401、按照预设规则，从视频中获取6帧关键帧图片。
步骤402、获取原始预览图片。
这里，原始预览图片是现有技术中的预览图片。该原始预览图片可以是视频中的某一帧图片，关键帧与该某一帧图片不能相同，原始预览图片还可以是非视频中的图片，例如海报图片、视频中几帧图片的合成图片等等。
步骤403、将原始预览图片和6帧关键帧图片合成预览图片。
步骤404、在预览图片中获取7帧图片所在区域。
这里，7帧图片包括1帧原始预览图片和6帧关键帧图片。
步骤405、设置7帧图片的区域的响应信息。
这里，每一帧图片所在的区域对应着响应信息是不同，以区别每一帧图片。
步骤406、根据7帧图片所在区域的响应信息、6帧关键帧图片对应的视频时间点和原始预览图片对应的初始时间点，生成所述响应信息和视频时间点的对应关系。
这里，第1帧关键帧图片所在区域的响应信息和第1帧关键帧图片的视频时间点对应；第2帧关键帧图片所在区域的响应信息和第2帧关键帧图片的视频时间点对应；第3帧关键帧图片所在区域的响应信息和第3帧关键帧图片的视频时间点对应；第4帧关键帧图片所在区域的响应信息和第4帧关键帧图片的视频时间点对应；第5帧关键帧图片所在区域的响应信息和第5帧关键帧图片的视频时间点对应；第6帧关键帧图片所在区域的响应信息和第6帧关键帧图片的视频时间点对应；原始预览图片所在区域的响应信息和视频的初始时间点相对应。一般情况下，初始时间点是0分0秒。
步骤407、获取用户点击预览图片的第一响应信息。
用户可以通过食指点击屏幕上的预览图片，生成第一响应信息。
步骤408、根据响应信息和视频时间点的对应关系，确定第一响应信息对应的视频时间点。
这里，第一响应信息对应视频时间点，也就是第一响应信息对应的某一关键帧图片或者原始预览图片的视频时间点。
步骤409、从第一响应信息对应的视频时间点播放视频。
值得说明的是，若本实施例中该视频不显示预览图片，也就是说图片合成失败，则显示原始预览图片。在步骤407之后，步骤408之前，本实施还可以包括判断当前显示的是否是预览图片，若是，才执行408；若否，则按照现有技术的流程进行处理。
