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。
图2为如图1所示的移动终端的一种无线通信系统示意图，以下将参考图2描述根据本发明实施例提供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类型的系统。

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、消息收发和其它类型的通信。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。
基于上述移动终端的硬件结构、通信系统的结构，提出本发明实施例提供的音视频定位装置和方法的以下实施例。
如图3所示，为本发明实施例提供的一种音视频定位装置的结构示意图，本发明实施例提供的音视频定位装置可以包括：检测单元110、计算单元120和定位单元130。
检测单元110，设置为：检测施加在音视频的拖动条上的第一压力。
随着科技的发展，越来越多的产品中引入了压力触控技术。相关技术中的压力触控技术是在移动终端的屏幕四角配置了力度传感器，该力度传感器可以感知用户对屏幕施加的按压力度，从而进行轻点、轻按、重按三层维度的动作回馈。这样可以让触控交互从长按的“时间”维度延伸至重压的“力度”维度，为人机交互开拓出了全新的空间。
本发明实施例就是将这种压力触控技术引入音视频定位控制中，解决相关技术中存在的音视频定位精度较差的问题。压力触摸屏的引入使得音视频在定位方面的交互有了更多的实现方式，可以通过压力触摸屏的不同压力感应，来缩短拖动条的控制范围。本发明实施例提供的技术方案的设计思路是：预先设置不同的压力等级，根据不同的压力等级确定出相应的缩小等级，根据该缩小等级对应的缩小比例计算出不同的拖动条的控制范围，其中，拖动条的像素长度是始终不变的。
在本发明实施例中，不限制播放音视频的移动终端中使用何种形式的压力检测方法以及使用何种压力检测装置，并且该压力检测装置可以是一个或多个。
计算单元120，设置为：根据检测单元110检测到的第一压力计算拖动条的第一控制范围。
在本发明实施例中，根据检测单元110检测出施加在移动终端触摸屏的拖动条上的第一压力以后，就可以根据该第一压力的施加位置计算拖动条的第一控制范围了。在以下实施例中会详细介绍如何通过检测到的第一压力计算拖动条的第一控制范围。
定位单元130，设置为：保持拖动条的像素长度不变，根据计算单元120计算出的第一控制范围对音视频进行定位。
在本发明实施例提供的音视频定位装置中，通过上述计算单元120计算出拖动条的第一控制范围以后，保持该拖动条的像素长度不变，便可以以更高的精度对音视频进行定位了，实际定位方法本发明实施例中不做限制，任何能够实现本发明实施例提供的技术方案的定位方法都在本发明实施例的保护范围之内。
在本发明实施例中，通过本发明实施例提供的技术方案对拖动条的控制范围缩小以后，即计算出拖动条的第一控制范围后，使得在保持该拖动条的像素长度不变的情况下，拖动条的控制精度提高了，例如，在未采用本发明实施例提供的技术方案之前，拖动条的控制精度例如是5秒，在采用本发明实施例提供的技术方案以后，该拖动条的控制精度例如缩短到1秒，控制精度的缩小有可以使得用户更精确地在音视频上进行定位，获得用户需要的时间点上的那段音频或视频，显著地提高了用户的体验感。
本发明实施例提供的音视频定位装置，通过检测单元检测施加在音视频的拖动条上的第一压力，计算单元根据检测到的第一压力计算拖动条的第一控制范围，定位单元可以保持拖动条的像素长度不变，并根据第一控制范围对音视频进行定位；通过本发明实施例提供的装置，可以实现提高音视频交互中音视频的定位精度的目的，从而提高用户体验感。
可选地，图4为本发明实施例提供的音视频定位装置中一种计算单元计算拖动条的第一控制范围的流程图。本发明实施例中的计算单元120根据检测单元110检测到的第一压力计算拖动条的第一控制范围包括如下步骤，即S101～S106：
S101、确定第一压力在拖动条上的施加位置，并在该拖动条的初始控制范围内的音视频时长上确定出该施加位置所处的时间点。
在本发明实施例中，拖动条的初始控制范围是指，在检测单元110检测到第一压力之前，拖动条当前控制的一个音视频上的部分或全部音视频，例如，设定一个视频的全部视频时长为2000秒，即从0秒开始，到2000秒结束， 如果在检测到第一压力之前，拖动条正在控制该视频上的500秒到1000秒之间的视频，则该500秒到1000秒之间的视频就是拖动条的初始控制范围。通常地，在刚打开音视频时，将整个音视频的时长作为拖动条的初始控制范围。
在本发明实施例中，通过检测单元110检测出有第一压力施加在拖动条上时，首先会确定出该第一压力在拖动条上的施加位置，随后，根据该施加位置，可以在拖动条的初始控制范围内的音视频时长上确定出该施加位置对应的一个时间点。例如，当拖动条的初始控制范围为500秒到1000秒之间的视频，确定该施加位置在这段视频的700秒处。需要说明的是，该时间点的实际确定方法本发明实施例不做限制，任何能够实现本发明实施例提供的技术方案的方法都在本发明实施例的保护范围之内。
可选地，在本发明实施例中，为了实现对拖动条的控制范围的按级别进行控制，这里将压力等级引入本发明实施例提供的技术方案中，预先设置多个第一压力等级，检测到相应的第一压力等级时，根据该第一压力等级对应的第一缩小等级对拖动条的控制范围进形缩小。因此，在本发明实施例提供的技术方案中，在检测出施加在拖动条上的第一压力并确定该第一压力的施加时间点以后，还需要确定该第一压力对应的第一压力等级。
可选地，在本发明实施例中，检测单元110，还设置为：在计算单元120根据检测到的第一压力计算拖动条的第一控制范围之前，检测该第一压力的第一压力等级。
在本发明实施例中，检测单元110检测第一压力的第一压力等级可以是检测该第一压力的力度等级，检测方法可以包括：
确定第一压力的第一压力值；将第一压力值与预设的多个按压力度范围进行比较，当第一压力值属于多个按压力度范围中的其中一个按压力度范围时，将第一压力确定为所属的按压力度范围对应的力度等级。
在本发明实施例中，为了明确所施加的第一压力的大小，可以预先将不同的压力值定义为不同的力度等级，如力度等级1、力度等级2、力度等级3……依此类推。每个力度等级设置对应的压力值的大小，可以依据不同的用户进行不同的定义。举例来说，对于年轻人来说，力量较大，在设置力度 等级时，每一个力度等级中可以设置为对应较大的压力值，例如，将50g-60g设置为属于力度等级1、将60g-70g设置为属于力度等级2、将70g-80g设置为属于力度等级3，需要说明的是，由于重力加速度恒定，这里以重量来表示压力的大小，以下描述同理；再举例来说，对于老年人和儿童来说，力量较小，在设置力度等级时，每一个力度等级中可以设置为对应较小的压力值，例如，将20g-35g设置为属于力度等级1、将35g-50g设置为属于力度等级2、将50g-65g设置为属于力度等级3。上述内容仅是本发明实施例中的一个示意性说明，在本发明的其它实施例中，也可以根据不同的应用场景对力度等级以及每个力度等级对应的压力值的大小做相应的调整。
在上述内容中，详细介绍了如何对第一压力的力度等级进行预定义。下面通过一些可选实施例详细介绍如何通过预定的第一压力的力度等级范围确定施加在移动终端上的第一压力的力度等级。这里继续以上述实施例中定义的年轻人的力度等级范围为例来进行说明，在上述实施例中，已经提到，对于年轻人来说，力量较大，在设置力度等级时，每一个力度等级中可以设置为对应较大的压力值，例如，将50g-60g设置为属于力度等级1、将60g-70g设置为属于力度等级2、将70g-80g设置为属于力度等级3，需要说明的是，由于重力加速度恒定，这里以重量来表示压力的大小，以下描述同理；仍以此范围为例，如果外界对移动终端施加了上述第一压力，检测到该第一压力的压力值大小为75g，这时将这个压力值大小为75g的第一压力分别与上述的每个力度等级的压力范围(即50g-60g、60g-70g、70g-80g)进行比较，根据比较结果可知，这个压力值大小为75g的第一压力属于70g-80g的按压力度范围内，并且该70g-80g的力度范围对应预先设置的力度等级3，因此将外界对终端施加的这个75g的力确定为力度等级3。
需要说明的是，上述内容仅是本发明实施例确定力度等级的示意性描述，任何与上述实施例相同或相似的技术方案，以及上述实施例的变体都在本发明实施例的保护范围之内，并且上述实施例和本发明涉及的任何基本技术方案特征的任意组合也均在本发明实施例的保护范围之内。
可选地，在本发明实施例中，检测单元110在确定第一压力的第一压力值之后，且在将该第一压力值与预设的多个按压力度范围进行比较之前，还 设置为：
将第一压力维持在第一压力值的持续时间与预设的持续时间阈值进行比较。
在本发明实施例中，检测单元110将第一压力值与预设的多个按压力度范围进行比较的实现方式，可以包括：当第一压力维持在第一压力值的持续时间大于预设的持续时间阈值时，将第一压力值与预设的不同按压力度范围进行比较。
可选地，在本发明实施例中，检测单元110还设置为：当第一压力维持在第一压力值的持续时间小于或等于预设的持续时间阈值时，忽略该第一压力。
在本发明实施例中，对于检测到的一个按压的压力值来说，该压力值必须能够维持一定的时间，不能将任意的一个达到预定压力值的按压确定为这个按压有效，这是毫无意义的。例如，若将由于突然地撞击或挤压造成的瞬间压力当作有效压力值来处理，从而触发拍摄终端的相应拍摄模式，这无疑会为用户带来诸多烦恼，因此，为了防止这些误操作的发生，本发明实施例可以对该按压的压力值进行一定的限制，达到该限制的压力值才能作为有效按压，上述对该压力值预先设置的持续时间阈值就是本发明实施例提供的技术方案对所施加压力的一种限制条件，只有该按压的压力值的维持时间大于持续时间阈值时，该按压才能作为有效按压。本发明实施例中设置的持续时间阈值可以根据不同的应用场景进行不同的设置，例如，对于年轻人来说，动作比较灵活，可以将该持续时间阈值设置的短一些，如1秒或0.5秒，检测到一个压力值持续了1秒或0.5秒就将该按压确定为有效按压；再例如，对于老年人、儿童以及残障人士来说，动作不太灵活，可以将该持续时间阈值设置的长一些，如2秒或3秒等，检测到一个压力值持续了2秒或3秒就将该按压确定为有效按压。在实际应用中，该持续时间阈值也不能设置的太短，以免任意的误操作就能达到该持续时间阈值，该持续时间阈值也不能设置的太长，以免播放音视频的移动终端长时间不反应时与移动终端的故障情况相混淆，给用户带来困惑。
需要说明的是，上述内容仅是本发明实施例的示意性说明，任何与上述 实施例相同或相似的技术方案，以及上述实施例的变体都在本发明实施例的保护范围之内，并且上述实施例和本发明涉及的任何基本技术方案特征的任意组合也均在本发明实施例的保护范围之内。
可选地，图5为本发明实施例提供的另一种音视频定位装置的结构示意图，在图3所示装置的结构基础上，本发明实施例提供的音视频定位装置还可以包括确定单元140。
确定单元140，设置为：根据检测单元110检测出的第一压力等级确定拖动条的第一缩小等级。其中，该第一压力等级与拖动条的第一缩小等级一一对应，该拖动条的第一缩小等级与不同的缩小比例一一对应。
在本发明实施例中，通过以上技术方案，可以准确地获得第一压力的第一压力等级，根据该第一压力等级，可以根据预设的映射表获取与该第一压力等级相对应的拖动条的第一缩小等级。
举例来说，预设的第一压力等级为1级、2级、3级；分别对应的第一缩小等级为Ⅰ级、Ⅱ级、Ⅲ级；并设定第一缩小等级Ⅰ级对应的缩小比例为M、Ⅱ级对应的缩小比例为M×M、Ⅲ级对应的缩小比例为M×M×M。当检测单元110检测到施加的第一压力等级为1级时，确定单元140确定出对应的第一缩小等级为Ⅰ级，随后，可以根据Ⅰ级缩小等级对拖动条的控制范围进行缩小，即以缩小比例M进行缩小；当检测单元110检测到施加的第一压力等级为2级时，确定单元140确定出对应的第一缩小等级为Ⅱ级，随后，可以根据Ⅱ级缩小等级对拖动条的控制范围进行缩小，即以缩小比例M×M进行缩小；当检测单元110检测到施加的第一压力等级为3级时，确定单元140确定出对应的第一缩小等级为Ⅲ级，随后，可以根据Ⅲ级缩小等级对拖动条的控制范围进行缩小，即以缩小比例M×M×M进行缩小。其中，预设的缩放系数M可以根据不同的应用场景自行定义，例如，1/5、1/6等。
计算单元120，还设置为：根据确定单元140确定的拖动条的第一缩小等级计算拖动条的第一控制范围。
通过以上技术方案，可以准确地获得施加在拖动条上第一压力的第一压力等级，根据该第一压力等级便可以获得拖动条的第一缩小等级，根据该第 一缩小等级和第一压力的施加位置，可以通过执行S102～S106对拖动条的第一控制范围进行计算了。
S102、计算该时间点与初始控制范围内的音视频时长的初始时间点之间的第一时长。
在本发明实施例中，当拖动条的初始控制范围为500秒到1000秒之间的视频，确定第一压力的施加位置在这段视频的700秒处时，拖动条的初始控制范围内的视频时长的初始时间点为500秒处，则700秒与500秒之间的长度，即S102中的第一时长为200秒。
S103、计算该第一时长在初始控制范围内的音视频时长上所占的第一比值。
在本发明实施例中，获得了第一时长200秒后，已知初始控制范围内的音视频时长为1000-500＝500秒，则第一比值为200/500＝2/5。
S104、根据第一压力对应的第一缩小等级计算第一控制范围的控制时长。
在本发明实施例中，根据确定单元140确定出第一压力等级所对应的第一缩小等级以后，便可以确定该第一缩小等级下对应的缩小比例。设定当前确定的第一压力等级为1级，则第一缩小等级为Ⅰ级，对应的缩小比例为M，如果缩放系数为M＝1/5，由于初始控制范围内的音视频时长为1000-500＝500秒，则对拖动条的初始控制范围缩小后的控制时长为：500×1/5＝100秒，即第一控制范围的控制时长为100秒。
S105、根据第一比值和第一控制范围的控制时长计算该第一控制范围的起始控制时间点和结束控制时间点。
在本发明实施例中，通过上述S101～S105，已经获得了第一时长在初始控制范围内的音视频时长上所占的第一比值为2/5，以及对拖动条的初始控制范围缩小后的第一控制范围的控制时长100秒；根据这些数值，可以计算出该第一控制范围的起始控制时间点和结束控制时间点，计算方法如下所述。
可选地，图6为本发明实施例提供的音视频定位装置中一种计算单元计算第一控制范围的起始控制时间点和结束控制时间点的流程图。本发明实施 例的S105中，计算单元120根据第一比值和第一控制范围的控制时长计算该第一控制范围的起始控制时间点和结束控制时间点包括以下步骤，即S1051～S1053：
S1051、将第一比值与第一控制范围的控制时长相乘，获取第二时长。
在本发明实施例中，将2/5(即第一比值)×100秒(即第一控制范围的控制时长)＝40秒，这时，获得一个时间长度40秒，该40秒就是上述的第二时长。
S1052、将第一压力在拖动条上的施加位置所处的时间点减去第二时长，获取第一控制范围的起始控制时间点。
在本发明实施例中，通过上述实施例已知，第一压力在拖动条上的施加位置所处的时间点为700秒处，则700秒-40秒(即第二时长)＝660秒，这个660秒就是计算出的拖动条的初始控制范围缩小后，获得的第一控制范围的起始控制时间点。
S1053、将起始控制时间点加上第一控制范围的控制时长，获取该第一控制范围的结束控制时间点。
在本发明实施例中，通过上述步骤已经计算出，第一控制范围的起始控制时间点为660秒处，第一控制范围的控制时长为100秒，则结束控制时间点＝660+100＝760秒。
S106、将起始控制时间点和结束控制时间点之间的音视频时长作为拖动条的第一控制范围。
在本发明实施例中，第一控制范围的起始控制时间点为660秒，结束控制时间点为760秒，则660秒到760秒之间的视频就是缩小之后的拖动条的控制范围，即拖动条的第一控制范围。
通过上述步骤(即S101～S106)可以根据检测出的第一压力等级准确地计算出拖动条的第一控制范围。
需要说明的是，上述内容仅是本发明实施例的示意性说明，任何与上述实施例相同或相似的技术方案，以及上述实施例的变体都在本发明实施例的保护范围之内，并且上述实施例和本发明涉及的任何基本技术方案特征的任 意组合也均在本发明实施例的保护范围之内。
通过上述技术方案可以计算出拖动条的第一控制范围，从而可以对音视频实施精确的定位控制。但是，在某些情况下，采用本发明实施例提供的技术方案对拖动条的控制范围缩小一次后，即缩小到第一控制范围后，可能还不能得到用户需要的音视频。针对这一问题，本发明实施例采用了逐级缩小拖动条的控制范围的技术方案，即在对拖动条的控制范围缩小一次后仍然不能满足定位精度要求的情况下，在此缩小的拖动条的第一控制范围的基础上，再次采用施加在拖动条上的第二压力对应的第二缩小等级对拖动条的控制范围进行再次缩小，以达到逐级提高控制精度的目的，即达到提高定位精度的目的。在实际应用中，可以通过以下技术方案对拖动条的控制范围进行逐级缩小。
可选地，图7为本发明实施例提供的又一种音视频定位装置的结构示意图，在图5所示装置的结构基础上，本实施例提供的音视频定位装置还可以包括：显示单元150。
显示单元150，设置为：在计算单元120根据第一压力等级计算出拖动条的第一控制范围后，显示具有第一控制范围的拖动条。
在本发明实施例中，如果检测出第一压力等级为1级，在该第一压力等级下，通过S101～S106计算出拖动条的第一控制范围以后，显示单元150会在播放音视频的移动终端交互界面上显示具有第一控制范围的拖动条，并在音视频定位期间保留该拖动条，通过该窗口对音视频进行定位，这时，如果通过该拖动条还是不能获得用户需要的音视频片段，用户可以在该拖动条上继续施加第二压力，获得相应的第二缩小等级后，继续对该拖动条的第一控制范围进行缩小。当然，对于拖动条的控制范围的缩小也不是无限进行下去的，当拖动条的控制范围一直缩小，直到拖动条的控制精度超过到当前使用的音视频终端的设置精度时，移动终端会通过交互界面提醒用户不能再缩小，或提醒出错。实际应用中的提醒方式本发明实施例中不做限制，例如，警示框、振动或响铃等。
检测单元110，还设置为：检测施加在具有第一控制范围的拖动条上的 第二压力对应的第二压力等级。
在本发明实施例中，检测单元110可以继续检测施加在具有第一控制范围的拖动条上的第二压力，并继续检测该第二压力的压力等级。
确定单元140，还设置为：根据检测单元110检测出的第二压力对应的第二压力等级确定该拖动条的第二缩小等级。
在本发明实施例中，通过上述单元执行的操作，确定单元140可以根据检测单元110检测出的第二压力等级确定对应的第二缩小等级，从而获取该第二缩小等级对应的缩小比例。
计算单元120，还设置为：将第一控制范围作为拖动条的初始控制范围；根据确定单元140确定出的第二缩小等级和拖动条的初始控制范围计算该拖动条的第二控制范围。可选地，在刚打开音视频时，可以将整个音视频时长作为拖动条的初始控制范围。
在本发明实施例中，计算单元120还可以继续通过上述S101～S106计算出拖动条的第三控制范围，计算该第三控制范围的实现方式与上述实施例中计算第一控制范围和第二控制范围的实现方式相同，故在此不再赘述。
需要说明的是，本发明实施例提供的技术方案中描述的缩小等级或缩放系数的设置方式只是示例性说明，实际应用中可以根据播放音视频的移动终端的性能定位对缩小后的控制范围进行灵活设置。例如，如果当前播放音视频的移动终端的定位最小单位是秒级别，则拖动条对上述第一压力和第二压力的响应无需响应到秒以下级别。
图8为使用本发明实施例提供的音视频定位装置执行音视频定位的一种应用场景示意图。以下结合图8，通过一些实例对本发明实施例提供的技术方案进行详细说明。
设定一段视频的时长为6000s，该视频播放的当前位置为2500s的位置，预先设置的拖动条的第一缩小等级有两级，即1级和2级，预先设置的缩放系数M为1/5，并且拖动条的长度(像素)为1000。
由图7可知，未触发按压的初始状态，拖动条的初始控制范围为0s——6000s，也就是说将拖动条拖到起始点，将定位到0s的位置，拖到终止点将定位到6000s的位置，即拖动条实现了用1000的长度来控制6000s(即6000s-0s)的移动定位，每1个长度(像素)的移动，实现6s级别的定位。
触发一级按压后，拖动条的第一控制范围变到了2000s——3200s，也就是说在一级按压状态下，将拖动条拖到起始点，将定位到2000s的位置，将拖动条拖到终止点，将定位到3200s的位置，即拖动条实现了用1000的长度来控制1200s(即3200s-2000s)的移动定位，每1个长度(像素)的移动，实现1s级别的定位。
触发二级按压后，拖动条的第二控制范围变到了2400s——2640s，也就是说在二级按压状态下，将拖动条拖到起始点，将定位到2400s的位置，将拖动条拖到终止点，将定位到2640s的位置，即拖动条实现了用1000的长度来控制240s(即2640s-2400s)的移动定位，每1个长度(像素)的移动，实现0.24s级别的定位。
本发明实施例提供的技术方案，对于时长较长的视频，通过感触拖动条控制器的按压力度不同，而设置拖动条的控制范围，可以有效的增加了拖动条的控制精度。
需要说明的是，上述内容仅是本发明实施例的示意性说明，任何与上述实施例相同或相似的技术方案，以及上述实施例的变体都在本发明实施例的保护范围之内，并且上述实施例和本发明涉及的任何基本技术方案特征的任意组合也均在本发明实施例的保护范围之内。
