具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
在本申请实施例中，多媒体数据是指由多个时间点的多媒体帧按序排列所构成的数据序列，该多媒体帧可以是音频帧或者视频帧，对此不作限定；也就是说，本申请实施例所提及的多媒体数据可以是音乐或者视频，对此不作限定。所谓的音乐可理解成由多帧音频帧按序排列所构成的音频序列，其可分为流行音乐、古典音乐、戏曲音乐，等等。所谓的视频可理解成由多帧图像帧按序排列所构成的图像序列，其可分为影视视频、综艺视频、 自媒体视频、游戏视频等等；其中，影视视频是指：在指定拍摄场景中，按照事先制作好的剧本对人物和/或动物的表演过程以及周围的环境进行录制，并后期加上音频、特效等制作而成的视频；综艺视频是指：一种综合多种艺术形式并带有娱乐性的视频；自媒体视频是指：普通大众采用摄像设备对某个场景进行拍摄，且通过网络等途径向外发布的视频，如vlog(video blog，视频记录/视频博客/视频网络日志)；游戏视频是指：在一个或多个玩家用户玩耍游戏的过程中，对任一玩家用户的终端屏幕中所显示的游戏画面，或者对观看该任一玩家用户的游戏过程的观看用户的终端屏幕中所显示的游戏画面进行屏幕录制而成的视频。针对任一视频而言，其均有一个预设播放时长；当某视频的预设播放时长小于时长阈值时，可将该视频称作短视频，当某视频的预设播放时长大于时长阈值时，可将该视频称作长视频。
为了实现更好地进行多媒体播放，本申请实施例提出了一种多媒体播放方案；该多媒体播放方案的大致原理如下：在为目标用户播放某个多媒体数据(设多媒体数据X)的过程，在检测到媒体切换操作的情况下，可切换至另一个多媒体数据(设多媒体数据Y)，并根据目标用户的用户偏好画像和多媒体数据Y的热点信息等一种或多种信息，将多媒体数据Y的起始播放点调整至目标用户感兴趣的播放点，以播放该多媒体数据Y，从而实现在较大程度上提升多媒体数据Y对于目标用户的吸引力，使得目标用户更愿意继续播放多媒体数据Y，进而提升多媒体数据Y的用户粘度和播放转化率。所谓的播放转化率是指有效播放次数和总播放次数的比例，当一个多媒体数据的被播放时长大于设定阈值时，可认为该多媒体数据被有效播放。在播放多媒体数据Y的过程中，在检测到目标触发操作的情况下，还可从检测到目标触发操作时所播放的多媒体帧，切换播放多媒体数据Y中目标用户感兴趣的另一个播放点的多媒体帧，从而进一步提升多媒体数据Y对于目标用户的吸引力，进一步提升多媒体数据Y的用户粘度。这样的多媒体播放方式，无需目标用户手动查找并播放感兴趣的多媒体帧，可有效提升多媒体数据的播放效率；并且还可减少播放目标用户不感兴趣的无效多媒体帧，从而节省处理资源以及有效提升第二多媒体数据的播放有效性。
其中，目标用户的用户偏好画像是指用于刻画目标用户的偏好(兴趣)的数据，多媒体数据Y的热点信息可用于指示多媒体数据Y中具有较高热度值的多媒体帧，热度值是一种用于反映多媒体帧的受欢迎程度。通常情况下，热度值越高，则表明播放多媒体帧的人数越多，进而表明该多媒体帧的受欢迎程度越高，该多媒体帧能够引起用户兴趣的概率越高。多媒体数据Y可以是由目标用户根据自身需求指定的多媒体数据，也可以是根据目标用户的用户偏好画像从数据库中选取的多媒体数据，还可以是与多媒体数据X属于同一数据集中的其他多媒体数据，本申请实施例对此不作限制。例如，目标用户在多媒体数据X的播放过程中，选择了多媒体数据1，则可将多媒体数据1作为多媒体数据Y；又如，根据目标用户的用户偏好画像预测出目标用户可能对多媒体数据2感兴趣，则可将多媒体数据2作为多媒体数据Y；再如，多媒体数据X所处的数据集中还包括多媒体数据3、多媒体数据4等，则可将多媒体数据3或多媒体数据4作为多媒体数据Y，等等。
在一种可能的实现中，该多媒体播放方案可由计算机设备执行，计算机设备例如可以是目标终端，此处所提及的目标终端可包括但不限于：智能手机、平板电脑、笔记本电脑、台式计算机、智能电视等；目标终端内均可运行各式各样的应用(application，APP)，如视频播放应用、音乐播放应用、社交应用、浏览器应用、信息流应用、教育应用，等等。另一种可能的实现中，计算机设备例如可以包括目标终端和服务器，即该多媒体播放方案还可由目标终端和服务器共同执行，在此情况下，目标终端和服务器可以通过网络连接。此处的服务器可以是独立的物理服务器，也可以是多个物理服务器构成的服务器集群或者分布式系统，还可以是提供云服务、云数据库、云计算、云函数、云存储、网络服务、云通信、中间件服务、域名服务、安全服务、CDN(Content Delivery Network，内容分发网络)、以及大数据和人工智能平台等基础云计算服务的云服务器，等等，对此不作限定。
当多媒体播放方案由目标终端和服务器共同执行时，目标终端可负责执行多媒体数据X和多媒体数据Y的播放操作，服务器可负责执行根据目标用户的用户偏好画像和多媒体数据Y的热点信息等一种或多种信息，在多媒体数据Y确定目标用户感兴趣的播放点的操作，以及执行将确定出的播放点的指示信息下发给目标终端的操作，使得目标终端可根据该指示信息所指示的播放点播放该多媒体数据Y，如图1a所示。例如，以多媒体数据X为视频X，多媒体数据Y为视频Y为例，若服务器根据用户偏好画像确定目标用户对视频Y中的第5秒处的图像帧感兴趣，以及对视频Y中的第58秒处的图像帧感兴趣，则可确定目标用户感兴趣的起播点11为第5秒和第58秒，因此可生成指示信息“视频Y-第5秒”以及指示信息“视频Y-第58秒”，并将各个指示信息下发给目标终端，使得目标终端在确定存在媒体切换操作时，若正在播放视频X中第1分50秒处的图像帧12，则可从该图像帧12切换至视频Y中第5秒处的图像帧13进行显示，并继续显示视频Y中位于第5秒之后的各图像帧，如图1b所示。当目标终端在确定存在目标触发操作时，若正在播放视频Y中第30秒处的图像帧，则还可从该第30秒处的图像帧切换至视频Y中第58秒处的图像帧进行显示，并继续显示视频Y中位于第58秒之后的各帧图像帧。应理解的是，本申请实施例只是以视频Y中包括两个目标用户感兴趣的起播点为例进行说明的，在实际应用中，根据目标用户的用户偏好画像所确定的目标用户感兴趣的起播点的数量不局限于2个，可以是3个、4个，甚至更多。
基于上述多媒体播放方案的相关描述，本申请实施例还提出了一种多媒体播放方法，该多媒体播放方法可由上述所提及的目标终端执行，或者由目标终端和服务器共同执行。为便于阐述，本申请实施例主要以目标终端执行该多媒体播放方法为例进行说明；参加图2所示，该多媒体播放方法可包括以下S201-S203：
S201，播放第一多媒体数据。
其中，第一多媒体数据可以是第一数据集中的任一多媒体数据，第一数据集中的各个多媒体数据按序排列且被按序播放。该第一数据集可以是视频集(如包含多个影视视频的影视剧、包含某一游戏的多个游戏视频的视频集锦、包含多个短视频的视频集锦，等等)，或者该第一数据集也可以是音乐集(如某一歌手的音乐专辑、包含多首热门音乐的音乐集 锦、包含同一音乐风格(如抒情风格、摇滚风格等)下的多首音乐的音乐集锦、包含多首戏曲的戏曲集锦，等等)。相应的，第一多媒体数据可以是视频集中的任一视频(如影视视频、游戏视频、短视频等)，或者音乐集中的任一音乐(如热门音乐、戏曲等)，本申请实施例对此不作限制。特别说明的是：针对短视频场景，一个数据集可以是由一个视频频道下的各个短视频构成的，也就是说，一个数据集对应一个视频频道；此处的视频频道可包括但不限于：视频推荐频道、视频关注频道、同城频道，等等。或者，一个数据集可以是关于同一主题(或话题)下的各个短视频构成的，此处的主题可包括：旅游主题、美食主题、搞笑主题，等等；又或者，一个数据集还可以是由同一用户发布的各个短视频构成的，等等。
该第一多媒体数据可包括多个时间点的多媒体帧，此处所提及的“多个”的含义是指至少两个。目标终端在为目标用户(即使用目标终端的用户)播放第一多媒体数据时，可从第一多媒体数据中的第一个时间点的多媒体帧(即首帧多媒体帧)起，开始播放第一多媒体数据；也可以从第一多媒体数据的第一起播点的多媒体帧起，开始播放第一多媒体数据，本申请实施例对此不作限定。其中，第一起播点是指根据目标用户的用户偏好画像和第一多媒体数据的热点信息中的至少一项信息，从第一多媒体数据的多个时间点中确定的目标用户可能感兴趣的时间点。通过从第一起播点开始播放第一多媒体数据，可在较大程度上迅速吸引目标用户的注意力，从而使得目标用户更愿意继续播放第一多媒体数据，可有效提升第一多媒体数据的用户粘度；并且，通过减少无效多媒体帧(即目标用户不感兴趣的多媒体帧)的播放，还可有效节省处理资源，以及提升第一多媒体数据的播放效率。
在第一多媒体数据的播放过程中，目标用户可通过输入不同的媒体切换操作，触发目标终端从相应的数据集中选取第二多媒体数据，并从第一多媒体数据切换至第二多媒体数据进行播放；相应的，若目标终端检测到该媒体切换操作，可执行S202。在一种可能的实现方式中，媒体切换操作可包括用于指示在同一数据集中进行多媒体切换的第一交互操作，或者用于指示在不同数据集中进行多媒体切换的第二交互操作等等。任一交互操作可通过以下任一种方式输入：手势，语音，触发终端屏幕中的切换元素，触发终端物理按键(如音量键、电源键等)；其中，切换元素可包括切换组件或终端屏幕中的空白区域，该切换组件是在第一多媒体数据的播放过程中，被显示在终端屏幕中的。
当任一交互操作是通过手势输入时，第一交互操作可包括输入第一手势的操作，第二交互操作可包括输入第二手势的操作。此处所提及的第一手势和第二手势均可以是预先根据经验值或者业务需求设置的，也可以是由目标用户通过目标终端结合自身需求设置，对此不作限定。例如：第一手势可以是左右滑动的手势，第二手势可以是上下滑动的手势；又如，第一手势可以是输入“M”的手势，第二手势可以是输入“N”的手势，等等。需说明的是：目标用户可以通过触摸终端屏幕的方式输入第一手势或者第二手势，也可通过隔空感应的方式输入第一手势或者第二手势，对此不作限制。在目标用户通过隔空感应的方式输入第一手势或者第二手势的情况下，目标用户可不触摸终端屏幕，而是对着目标终端 的摄像组件(如前置摄像头)比划第一手势或者第二手势，使得目标终端可通过摄像组件获取该第一手势或者第二手势。
当任一交互操作是通过语音输入时，第一交互操作可包括输入第一语音的操作，第二交互操作可包括输入第二语音的操作。此处所提及的第一语音和第二语音可预先根据经验值或者业务需求设置的，也可以是由目标用户通过目标终端结合自身需求设置，对此不作限定。例如，第一语音可以是“请在同一数据集中进行媒体切换”，第二语音可以是“请在不同数据集中进行媒体切换”；又如，第一语音可以是“切换至同一数据集中的下一个多媒体数据”，第二语音可以是“切换至上一个数据集”，等等。
当任一交互操作是通过触发终端屏幕中的切换元素输入时，第一交互操作和第二交互操作可以是通过触发不同的切换元素输入的。在此情况下，目标终端的终端屏幕中可显示第一切换元素和第二切换元素。第一交互操作可包括针对终端屏幕中的第一切换元素(即第一空白区域或第一切换组件)的触发操作；第二交互操作可包括针对终端屏幕中的第二切换组件(即第二空白区域或第二切换组件)的触发操作。上述所提及的第一空白区域、第二空白区域、第一切换组件和第二切换组件的数量均可以是一个或多个，对此不作限定。或者，第一交互操作或者第二交互操作也可以是通过不同的触发操作来触发同一切换元素输入的。在此情况下，目标终端的终端屏幕中可显示一个目标切换元素(即目标空白区域或目标切换组件)。第一交互操作可包括针对目标切换元素的第一触发操作(如双击操作、单击操作)；第二交互操作可包括针对目标切换元素的第二触发操作(如长按操作)，等等。
当任一交互操作是通过触发终端物理按键输入时，第一交互操作和第二交互操作可以是通过触发不同的终端物理按键输入的。在此情况下，目标终端可配置第一终端物理按键和第二终端物理按键。第一交互操作可包括针对第一终端物理按键(如音量键)的触发操作；第二交互操作可包括针对第二终端物理按键(如电源键)的触发操作。此处所提及的第一终端物理按键和第二终端物理按键的数量均可以是一个或多个，对此不作限定。或者，第一交互操作或者第二交互操作也可以是通过不同的触发操作来触发同一终端物理按键输入的。在此情况下，目标终端可配置目标终端物理按键。第一交互操作可包括针对目标终端物理按键的第一触发操作(如双击操作)；第二交互操作可包括针对目标终端物理按键的第二触发操作(如长按操作)，等等。
S202，当存在媒体切换操作的情况下，基于第二多媒体数据的目标起播点，从第一多媒体数据切换至第二多媒体数据中处于目标起播点的多媒体帧进行播放。
其中，第二多媒体数据可包括多个时间点的多媒体帧，一个时间点对应一个多媒体帧。第二多媒体数据的多个时间点中可包括预先配置的P个候选起播点，P为大于1的正整数；目标起播点属于P个候选起播点，其具体可以是P个候选起播点中的第一个候选起播点，或者第二个候选起播点、又或者最后一个候选起播点，对此不作限定。在一种可能的实现中，可根据目标用户的用户偏好画像和第二多媒体数据的热点信息中的一种或多种信息， 预先配置P个候选起播点；也就是说，S202所提及的目标起播点可以是根据目标用户的用户偏好画像确定的，也可以是根据第二多媒体数据的热点信息确定的，还可以是根据目标用户的用户偏好画像和第二多媒体数据的热点信息共同确定的，对此不作限制。
可见，目标起播点本质上是第二多媒体数据的多个时间点中的其中一个时间点。基于此，S202的具体实施方式可以是：当存在媒体切换操作的情况下，播放目标起播点的目标多媒体帧，该目标多媒体帧是第二多媒体数据中处于目标起播点的多媒体帧；在目标多媒体帧播放结束后，继续播放第二多媒体数据中位于目标多媒体帧之后的剩余多媒体帧。其中，此处所提及的“继续播放”的含义可以包括：继续依次连续播放，或者继续跳帧播放，等等；如目标多媒体帧为第二多媒体数据的第5帧，那么继续依次连续播放则是指：继续播放第6帧、第7帧、第8帧…以此类推；继续跳帧播放则是指：继续播放第7帧、第8帧、第10帧…以此类推。
例如，设第一多媒体数据为音乐A，第二多媒体数据为音乐B，且音乐B中的第30秒为目标起播点；那么若在播放至音乐A的第3分15秒处的音频帧时，检测到存在媒体切换操作，则可从音乐A切换至音乐B，并开始播放音乐B的第30秒处的音频帧，以及连续播放音乐B中位于第30秒之后的各个音乐帧。又如，设第一多媒体数据为视频A，第二多媒体数据为视频B，且视频B中的第5秒为目标起播点；那么若在播放至视频A的第30分15秒处的图像帧时，检测到媒体切换操作，则可从视频A切换至视频B，并开始显示视频B的第5秒处的图像帧，以及继续播放视频B中位于第5秒之后的图像帧。
由前述可知，媒体切换操作可包括第一交互操作或者第二交互操作，第一交互操作是指示在同一个数据集中进行媒体切换的，而第二交互操作是指示在不同数据集中进行媒体切换的。因此可知，不同的媒体切换操作，会使得S202中所涉及的第二多媒体数据的确定方式也随之不同；在一种可能的实现方式中，该第二多媒体数据的确定方式如下：
(1)当媒体切换操作包括第一交互操作时，目标终端可从第一多媒体数据所处的第一数据集中确定第二多媒体数据，即此情况下，第二多媒体数据是第一数据集中，除第一多媒体数据之外的多媒体数据。其中，第一数据集中的各个多媒体数据按序排列且被按序播放，第二多媒体数据可以位于第一多媒体数据之前，也可以位于第一多媒体数据之后。可理解的是：当第二多媒体数据位于第一多媒体数据之前时，第二多媒体数据是一个已被播放过的多媒体数据；当第二多媒体数据位于第一多媒体数据之后时，第二多媒体数据是一个未被播放过的多媒体数据。在一种实施方式中，目标终端在检测到第一交互操作后，可默认从第一数据集中位于第一多媒体数据之后的多媒体数据中，选取第二多媒体数据。另一种实施方式中，目标终端在检测到第一交互操作后，可确定第一交互操作的操作信息；若第一交互操作的操作信息为第一信息，则可从第一数据集中位于第一多媒体数据之后的多媒体数据中，选取第二多媒体数据；若第一交互操作的操作信息为第二信息，则可从第一数据集中位于第一多媒体数据之前的多媒体数据中，选取第二多媒体数据。
例如：①当第一交互操作包括输入第一手势的操作时，第一交互操作的操作信息可包括第一手势的手势轨迹；第一信息可以是第一轨迹，第二信息可以是第二轨迹。举例说明，假设第一手势为左右滑动的手势，则第一轨迹可以是从左往右滑动的轨迹，第二轨迹可以是从右往左滑动的轨迹；假设第一手势为输入“M”的手势，则第一轨迹可以是从左往右绘制“M”的轨迹，第二轨迹可以是从右往左绘制“M”的轨迹。②当第一交互操作包括输入第一语音的操作时，第一交互操作的操作信息可包括第一语音的语音内容；第一信息可以是第一内容(如“切换播放同一数据集中的下一个多媒体数据”)，第二信息可以是第二内容(如“切换播放同一数据集中的上一个多媒体数据”)。③当第一交互操作包括针对第一切换元素的触发操作时，若第一切换元素的数量为2个及以上，则第一交互操作的操作信息可包括被触发的第一切换元素的元素标识；第一信息可以是第一个第一切换元素的元素标识，第二信息可以是第二个第一切换元素的元素标识。若第一切换元素的数量为一个，则第一交互操作的操作信息可包括针对第一切换元素的触发方式，第一信息可以是第一方式(如双击)，第二信息可以是第二方式(如长按)。④当第一交互操作是通过触发终端物理按键输入时，其涉及的操作信息与第一交互操作的第③种情况所提及的操作信息类似，在此不再赘述。
(2)当媒体切换操作包括第二交互操作时，目标终端可默认选取第二数据集中的首个多媒体数据作为第二多媒体数据；也可以根据目标用户的用户偏好画像，或第二多媒体数据的热点信息，或用户偏好画像和该第二多媒体数据的热点信息，从第二数据集中确定第二多媒体数据，即此情况下，第二多媒体数据是第二数据集中，根据目标用户的用户偏好画像和第二多媒体数据的热点信息中的一种或多种信息确定的多媒体数据。其中，第二数据集是从多媒体播放列表中除第一数据集以外的数据集中选取的，该多媒体列表中的各个数据集按序排列且被按序播放。第一数据集可以是多媒体播放列表中的第一个数据集，也可以是其他排列位置处的数据集，对此不作限定；位于第一数据集之后的数据集可以是：实时或定时地根据目标用户的用户偏好画像和第二多媒体数据的热点信息中的一种或多种信息确定的候选数据集，每个候选数据集中可包括至少一个根据用户偏好画像和第二多媒体数据的热点信息中的一种或多种信息所确定的多媒体数据。
本申请实施例所提及的第二数据集可以位于第一数据集之前，也可以位于第一数据集之后。可理解的是：当第二数据集位于第一数据集之前时，虽然第二数据集是一个已被播放过的数据集，但第二多媒体数据可能是已被播放的多媒体数据，也可能是未被播放过的多媒体数据，对此不作限定。例如，假设多媒体播放列表包括数据集A、数据集B…数据集G；且第一数据集为数据集B，第二数据集为数据集A，且第二多媒体数据为第二数据集中的第二个多媒体数据，那么若目标用户在播放了数据集A中的第一个多媒体数据后，便切换播放了数据集B，则此时的第二多媒体数据并未被播放过。当第二数据集位于第一数据集之后时，第二数据集是一个未被播放过的数据集，第二多媒体数据是一个未被播放过的多媒体数据。
目标终端从多媒体播放列表中选取第二数据集的方式可包括以下任一种：在一种实施方式中，目标终端在检测到第二交互操作后，可默认从多媒体推荐列表中位于第一数据集之后的数据集中，选取第二数据集。另一种实施方式中，目标终端在检测到第二交互操作后，可确定第二交互操作的操作信息；若第二交互操作的操作信息为第三信息，则可从多媒体播放列表中位于第一数据集之后的数据集中，选取第二数据集；若第二交互操作的操作信息为第四信息，则可从多媒体播放列表中位于第一数据集之前的数据集中，选取第二数据集。
例如：①当第二交互操作包括输入第二手势的操作时，第二交互操作的操作信息可包括第二手势的手势轨迹；第三信息可以是第三轨迹，第四信息可以是第四轨迹。举例说明，假设第二手势为上下滑动的手势，则第三轨迹可以是从上往下滑动的轨迹，第四轨迹可以是从下往上滑动的轨迹；假设第二手势为输入“N”的手势，则第三轨迹可以是从左往右绘制“N”的轨迹，第四轨迹可以是从右往左绘制“N”的轨迹。②当第二交互操作包括输入第二语音的操作时，第二交互操作的操作信息可包括第二语音的语音内容；第三信息可以是第三内容(如“切换播放上一数据集”)，第四信息可以是第四内容(如“切换播放下一数据集”)。③当第二交互操作包括针对第二切换元素的触发操作时，若第二切换元素的数量为2个及以上，则第二交互操作的操作信息可包括被触发的第二切换元素的元素标识；第三信息可以是第一个第二切换元素的元素标识，第四信息可以是第二个第二切换元素的元素标识。若第二切换元素的数量为一个，则第二交互操作的操作信息可包括针对第二切换元素的触发方式，第三信息可以是第三方式(如单击、双击等)，第四信息可以是第四方式(如按压、长按等)④当第二交互操作是通过触发终端物理按键输入时，其涉及的操作信息与第二交互操作的第③种情况所提及的操作信息类似，在此不再赘述。
基于上述S201-S202的相关描述，下面以第一多媒体数据为影视剧1中的视频B为例，结合几个具体的例子对目标用户通过输入不同的交互操作(即媒体切换操作)，触发终端切换播放不同的第二多媒体数据的具体场景作示例性说明：
例1，设任一交互操作是通过手势输入的，在播放视频B中的图像帧30时，若目标用户在终端屏幕中通过手指从左往右的滑动输入了第一手势(即第一交互操作)，则目标终端可在影视剧1中位于视频B之后的各个视频中选取视频C作为第二多媒体数据，视频C中的第5秒为目标起播点；然后，目标终端可从视频B中的图像帧30切换至视频C中的第5秒的图像帧31进行显示，并继续显示后续的图像帧，如图3a所示。若目标用户在终端屏幕中通过从右往左的滑动输入了第一手势，则目标终端可在影视剧1中位于视频B之前的各个视频中选取视频A作为第二多媒体数据，视频A中的第15秒为目标起播点；然后，目标终端可从视频B中的图像帧30切换至视频A中的第15秒的图像帧32进行显示，并继续显示后续的图像帧，如图3b所示。
若目标用户在终端屏幕中通过手指从上往下的滑动输入了第二手势(即第二交互操作)，则目标终端可在多媒体播放列表中位于影视剧1之前的各个影视剧集中选取影视剧集0作为第二数据集，并将影视剧集0中的视频d作为第二多媒体数据，视频d中的第16秒为目 标起播点；然后，目标终端可从视频B中的图像帧30切换至视频d中的第16秒的图像帧33进行显示，并继续显示后续的图像帧，如图3c所示。若目标用户在终端屏幕中通过手指从下往上的滑动输入了第二手势，则目标终端可在多媒体播放列表中位于影视剧1之后的各个影视剧集中选取影视剧集2作为第二数据集，并将影视剧集2中的视频f作为第二多媒体数据，视频f中的第36秒为目标起播点；然后，目标终端可从视频B中的图像帧30切换至视频f中的第36秒的图像帧34进行显示，并继续显示后续的图像帧，如图3d所示。
例2，设任一交互操作是通过触发切换组件输入的，目标终端可在终端屏幕中显示第一切换组件35和第二切换组件36，如图3e的左侧图所示。在播放视频B中的图像帧30时，若目标用户针对第一切换组件35执行了单击操作(即通过第一方式输入第一交互操作)，则目标终端可从视频B中的图像帧30切换至视频C中的第5秒的图像帧31进行显示；若目标用户针对第一切换组件35执行了双击操作(即通过第二方式输入第一交互操作)，则目标终端可从视频B中的图像帧30切换至视频A中的第15秒的图像帧32进行显示。若目标用户针对第二切换组件36执行了单击操作(即通过第三方式输入第二交互操作)，则目标终端可从视频B中的图像帧30切换至视频d中的第16秒的图像帧33进行显示；若目标用户针对第二切换组件36执行了双击操作(即通过第四方式输入第二交互操作)，则目标终端可从视频B中的图像帧30切换至视频f中的第36秒的图像帧34进行显示。
或者，第一切换组件和第二切换组件的数量均为2个，即目标终端可在终端屏幕中显示第一切换组件351、第一切换组件352、第二切换组件361以及第二切换组件362，如图3e的右侧图所示。在播放视频B中的图像帧30时，若目标用户针对第一切换组件351执行了触发操作，则目标终端可从视频B中的图像帧30切换至视频C中的第5秒的图像帧31进行显示；若目标用户针对第一切换组件352执行了触发操作，则目标终端可从视频B中的图像帧30切换至视频A中的第15秒的图像帧32进行显示。若目标用户针对第二切换组件361执行了触发操作，则目标终端可从视频B中的图像帧30切换至视频d中的第16秒的图像帧33进行显示；若目标用户针对第二切换组件362执行了触发操作，则目标终端可从视频B中的图像帧30切换至视频f中的第36秒的图像帧34进行显示。
应理解的是，图3a-图3e均只是示例性地表征目标终端在播放视频时的界面示意图，并不对此进行限定。例如，当终端屏幕包括切换组件时，该切换组件的产品形态并不局限于图3e所示；切换组件还可以是图3a-图3e中所示的“选集”组件，等等。还需说明的是：参见前述S201-S202的相关描述可知，第一多媒体数据和第二多媒体数据均可以是基于一个起播点开始播放的；那么同理，目标终端针对除第一多媒体数据和第二多媒体数据的其他多媒体数据，也可基于某个起播点开始播放。也就是说，目标终端针对任一多媒体数据，当不存在媒体切换操作的情况下，也可以根据目标用户的用户偏好画像和任一多媒体数据的热点信息中的一种或多种信息，确定任一多媒体数据的起播点，并基于确定的起播点开始播放任一多媒体数据。
S203，在第二多媒体数据的播放过程中，当存在目标触发操作的情况下，从第二多媒体数据中的第一多媒体帧切换播放新起播点的多媒体帧。
由于目标起播点是P个候选起播点中的其中一个候选起播点，而每个候选起播点均能在一定程度上吸引目标用户的注意力。基于此，目标终端在基于目标起播点播放第二多媒体数据的过程中，还可支持目标用户通过输入目标触发操作，以触发目标终端从第一多媒体帧(存在目标触发操作时所播放的多媒体帧)跳转至新起播点(P个候选起播点中除目标起播点之外的候选起播点)处的多媒体帧，从而实现快速切换播放目标用户感兴趣的新多媒体帧(即新起播点处的多媒体帧)，提升用户粘度和播放效率。相应的，在基于目标起播点播放第二多媒体数据的过程中，在检测到存在目标触发操作的情况下，可从第一多媒体帧切换播放新起播点的多媒体帧；并在新起播点的多媒体帧播放结束后，继续播放第二多媒体数据中位于新起播点之后的各个时间点的多媒体帧。
其中，目标触发操作可以根据经验值或者业务需求设置，也可以由目标用户根据自身需求通过目标终端进行设置，只需满足目标触发操作和前述所提及的媒体切换操作不冲突即可。在一种可能的实现中，目标用户可通过输入一个指定的目标触发操作，以触发目标终端从P个候选起播点中除目标起播点以外的各个候选起播点中，随机选取一个候选起播点作为新起播点。另一种可能的实现中，目标用户可通过输入不同的目标触发操作，以触发目标终端采用不同的起播点选取逻辑从P个候选起播点中选取新起播点。具体的，该目标触发操作可包括：用于指示在晚于第一多媒体帧所处的第一时间点的各个候选起播点中选取新起播点的第一进度调整操作(或称为“快进操作”)，或者用于指示在早于第一时间点的各个候选起播点中选取新起播点的第二进度调整操作(或称为“后退操作”)，或者针对P个候选起播点的自定义选择操作，等等。
其中，当目标触发操作包括针对P个候选起播点的自定义选择操作时，新起播点可以是指：根据自定义选择操作在P个候选起播点中确定的候选起播点。在一种实施方式中，可在终端屏幕中显示各个候选起播点的标识选项，则此实施方式下的自定义选择操作可包括：选中任一标识选项的操作；那么，新起播点是指被选中的标识选项对应的候选起播点。另一种实施方式中，可在终端屏幕中显示一个起播点组件，则此实施方式下的自定义选择操作可包括：针对起播点组件的自定义触发操作。其中，自定义触发操作可以是在预设时间段内单击或连续点击起播点组件的点击操作，此情况下，新起播点可以是指根据点击操作所涉及的点击次数确定的候选起播点；例如，当点击次数为1时，可将P个候选起播点中除目标时间点以外的时间最早的候选起播点；当点击次数为2时，可将P个候选起播点中除目标时间点以外的时间次早的候选起播点，等等。或者，自定义触发操作可以是长按起播点组件的长按操作，此情况下，新起播点可以是指根据长按操作所涉及的按压时长确定的候选起播点；例如，当按压时长为1秒时，可将P个候选起播点中除目标时间点以外的时间最早的候选起播点；当按压时长为2秒时，可将P个候选起播点中除目标时间点以外的时间次早的候选起播点，等等。
当目标触发操作包括第一进度调整操作时，新起播点可以是P个候选起播点中晚于第一多媒体帧所处的第一时间点的任一候选起播点；例如，新起播点可以是指P个候选起播点中晚于第一时间点，且离第一时间点最近的候选起播点，或者晚于第一时间点且离第一 时间点次进的候选起播点，或者晚于第一时间点的最后一个候选起播点，等等。当目标触发操作包括第二进度调整操作时，新起播点可以是指P个候选起播点中早于第一时间点的任一候选起播点；例如，新起播点可以是指P个候选起播点中早于第一时间点，且离第一时间点最近的候选起播点，或者早于第一时间点且离第一时间点次进的候选起播点，或者早于第一时间点的第一个候选起播点，等等；又如，该新起播点可以是指P个候选起播点中早于目标时间点，且离目标时间点最近的候选起播点，或者早于目标时间点且离目标时间点次近的候选起播点，等等。
应理解的是，与前述所提及的第一交互操作和第二交互操作类似，任一进度调整操作可通过以下任一种方式输入：手势，语音，触发终端屏幕中的进度调整元素，触发终端物理按键(如音量键、电源键等)，等等。也就是说，第一进度调整操作可以是输入第三手势或者第三语音的操作，或者是针对第一进度调整元素或第三终端物理按键的操作，等等；第二进度调整操作可以是输入第四手势或者第四语音的操作，或者是针对第二进度调整元素或第四终端物理按键的操作，等等。此处所提及的第三手势和第四手势可根据业务需求或者目标用户的用户需求(或操作习惯)确定，只需和前述所提及的第一手势和第二手势区分开即可。例如，若前述所提及的第一手势和第二手势为输入“M”和“N”的手势，则该第三手势和第四手势可以分别是从左往右滑动的手势，以及从右往左滑动的手势；又如，若前述所提及的第一手势和第二手势为从左往右滑动的手势和从右往左滑动的手势，则该第三手势和第四手势可以分别是输入“M”和“N”的手势，等等。
还需说明的是，第一进度调整操作和第二进度调整操作是输入从左往右滑动的手势，以及从右往左滑动的手势时，第一进度调整操作和第二进度调整操作的滑动幅度可以与新起播点的选取结果无关或相关。第一进度调整操作和第二进度调整操作的滑动幅度与新起播点的选取结果无关是指目标用户在输入第一进度调整操作或第二进度调整操作时，不管通过手指或者其他组件(如触摸笔)在终端屏幕上滑动了多少距离，均不会影响新起播点的选取结果。例如，第一进度调整操作具体指示选取位于第一时间点后，且离第一时间点最近的候选时间点作为新起播点，那么不管目标用户在输入第一进度调整操作时，通过手指或者其他组件(如触摸笔)在终端屏幕上滑动1厘米、还是5厘米，甚至10厘米，目标终端始终是选取位于第一时间点后，且离第一时间点最近的候选时间点作为新起播点。相应的，第一进度调整操作和第二进度调整操作的滑动幅度与新起播点的选取结果相关是指新起播点的选取结果受第一进度调整操作和第二进度调整操作的滑动幅度的影响；例如，第一进度调整操作指示选取位于第一时间点后的候选时间点作为新起播点，若目标用户在输入第一进度调整操作时，通过手指或者其他组件(如触摸笔)在终端屏幕上滑动1厘米，则目标终端可选取位于第一时间点后，且离第一时间点最近的候选时间点作为新起播点；若通过手指或者其他组件(如触摸笔)在终端屏幕上滑动5厘米，则目标终端可选取位于第一时间点后，且离第一时间点次近的候选时间点作为新起播点，等等。
基于上述S203的相关描述，下面以目标触发操作包括第一进度调整操作为例，结合图3f对如何切换播放新起播点的多媒体帧作示例性说明。具体的，例如设第二多媒体数据 如图3d所示的视频f，第二多媒体数据的P个候选起播点包括：第36秒、第5分36秒、以及第30分14秒；且设目标起播点为第36秒，那么目标终端在播放第36秒的目标图像帧之后，可接着继续播放位于36秒之后的剩余图像帧，若在第59秒时检测到第一进度调整操作，则可将第5分36秒作为新起播点，并从第59秒的图像帧(即第一媒体帧)切换播放第5分36秒的图像帧。应理解的是，图3f是以第二多媒体数据为目标视频为例进行说明的，当第二多媒体数据为音乐时，其实现方式与图3f所示的实现方式类似，在此不再赘述。
在一种可选的实施方式中，若目标起播点是多个时间点中除第一个时间点以外的时间点，则考虑到目标用户可能存在想要从第二多媒体数据的首帧多媒体帧(即第一个时间点的多媒体帧)开始播放。因此目标终端在基于目标起播点播放第二多媒体数据的过程中，还可支持目标用户通过输入首帧播放触发操作，以触发目标终端从当前播放的第二多媒体帧快速跳转至首帧多媒体帧，从而从首帧多媒体帧开始播放第二多媒体数据，提升用户粘度。其中，首帧播放触发操作可以根据经验值或者业务需求设置，也可以由目标用户根据自身需求通过目标终端进行设置，只需满足首帧播放触发操作和前述所提及的媒体切换操作以及目标触发操作(如第一进度调整操作、第二进度调整操作)不冲突即可。例如，首帧播放触发操作可以是输入第五手势(如画一个小圆圈的手势、输入“L”的手势，等等)或者第五语音的操作，或者是针对首帧播放触发组件或第五终端物理按键的操作，等等。
也就是说，在第二多媒体数据的播放过程中，即目标多媒体帧或剩余多媒体帧的播放过程中，当存在首帧播放触发操作的情况下，从第二多媒体帧切换播放第一个时间点的多媒体帧；并在第一个时间点的多媒体帧播放结束后，继续播放第二多媒体数据中位于第一个时间点之后的各个时间点的多媒体帧。其中，第二多媒体帧是指存在首帧播放触发操作时所播放的多媒体帧；例如，目标终端是在播放第35秒的多媒体帧时检测到首帧播放触发操作，则第二多媒体帧便是第35秒的多媒体帧。以第二多媒体数据为目标视频为例，目标终端响应首帧播放触发操作，从第二图像帧(第二多媒体帧)切换播放首帧图像帧(即第一个时间点的多媒体帧)的示意图可参见图3g所示。应理解的是，当第二多媒体数据为音乐时，其实现方式与图3g所示的实现方式类似，在此不再赘述。
本申请实施例可根据实际需求灵活地为第二多媒体数据预先配置P个候选起播点，使得在播放第一多媒体数据的过程中，在存在媒体切换操作的情况下，可灵活地从P个候选起播点中选取一个目标起播点，并基于第二多媒体数据的目标起播点，开始播放第二多媒体数据，可有效提升多媒体播放的灵活性。并且，在第二多媒体数据的播放过程中，在存在目标触发操作的情况下，还可通过定位切换播放点的方式，自动从第一多媒体帧快速切换至满足实际需求的另一多媒体帧(即新起播点的多媒体帧)，从而减少播放无效多媒体帧(未满足实际需求的多媒体帧)；这样不仅可进一步提升多媒体播放的灵活性，还可有效节省处理资源，有效提升第二多媒体数据的播放有效性和播放效率。
基于上述描述，本申请实施例还提出了一种多媒体播放方法，该多媒体播放方法可由上述所提及的目标终端执行，或者由目标终端和服务器共同执行。为便于阐述，本申请实 施例主要以目标终端执行该多媒体播放方法为例进行说明；参加图4所示，该多媒体播放方法可包括以下S401-S405：
S401，播放第一多媒体数据。
在播放第一多媒体数据的过程中，目标终端可获取数据库中的各个数据集的热度值，选取热度值较大的数据集作为候选数据集添加至多媒体推荐列表中，使得当存在第二交互操作时，从该多媒体推荐列表中选取第二数据集。或者，在播放第一多媒体数据的过程中，目标终端可获取目标用户的用户偏好画像；该用户偏好画像可以是根据目标用户的用户信息(如社交信息、周围环境信息等)所构建的初始的用户偏好画像，也可以是根据目标用户的多媒体历史播放信息对初始的用户偏好画像更新后的画像，对此不作限定。其中，该用户偏好画像可包括用于多媒体匹配的第一偏好标签，以及用于起播点匹配的第二偏好标签；此处所提及的第一偏好标签和第二偏好标签的数量可以均是一个或多个，对此不作限定。并且，第一偏好标签和第二偏好标签可以相同、不同或者部分相同；例如，第一偏好标签可以包括“悬疑剧”“搞笑”“情感”“明星X”，第二偏好标签可包括“搞笑”“明星X”“吃播”，等等。
在获取到用户偏好画像后，目标终端可在第一多媒体数据的播放过程中，根据用户偏好画像中的第一偏好标签，从数据库中检索匹配多媒体数据。所谓的匹配多媒体数据是指数据标签和第一偏好标签相匹配的多媒体数据，匹配多媒体数据包括一个或多个起播点。在一种实施方式中，目标终端可计算第一偏好标签的特征向量和数据库中的每个多媒体数据的数据标签的特征向量之间的相似度，将相似度大于相似阈值的数据标签所对应的多媒体数据作为匹配多媒体数据。另一种实施方式中，可预先设置标签映射表，该标签映射表中包括多个数据标签和多个预设偏好标签之间的映射关系，那么目标终端便可先判断标签映射表中的多个预设偏好标签中是否存在第一偏好标签，若存在，则将第一偏好标签所映射的数据标签对应的多媒体数据作为匹配多媒体数据。
然后，可获取匹配多媒体数据的标签信息集，匹配多媒体数据的标签信息集中包括匹配多媒体数据中的各个起播点的标签信息；在标签信息集中，检索与第二偏好标签相匹配的匹配标签信息；将匹配标签信息对应的起播点所属的匹配多媒体数据作为候选多媒体数据，并将候选多媒体数据所属的数据集作为候选数据集添加至多媒体推荐列表中，使得当存在第二交互操作时，从该多媒体推荐列表中选取第二数据集。若选取出的匹配多媒体数据的数量较多，则还可根据第一偏好标签的加权值和第二偏好标签的加权值对各个匹配多媒体数据进行权重计算，得到各个匹配多媒体数据的权重，从而按照权重从高到低的顺序选取预设数量个匹配多媒体数据作为候选多媒体数据。其中，任一匹配多媒体数据的权重的计算方式如下：获取任一匹配多媒体数据的数据标签和第一偏好标签之间的第一匹配度，以及任一匹配多媒体数据中的各个起播点的标签信息和第二偏好标签之间的第二匹配度，采用第一偏好标签的加权值对第一匹配度进行加权，得到第一加权值，以及采用第二偏好标签的加权值对第二匹配度进行加权，得到第二加权值，求取第一加权值和第二加权值的总和，得到任一匹配多媒体数据的权重。
需说明的是，由前述实施例中的S201的相关内容可知，多媒体推荐列表中除了包括候选数据集，还可包括第一数据集，且第一数据集的排列位置位于各个候选数据集的排列位置之前。考虑到目标用户可能会输入第二交互操作来触发在不同的数据集中进行多媒体切换，因此为便于后续在检测到第二交互操作时，可快速地为目标用户基于目标起播点进行第二多媒体数据的播放，目标终端可对多媒体推荐列表中的数据集进行预加载，使得在检测到第二交互操作后，可基于预加载的数据进行播放。考虑到当存在第二交互操作时，通常是从第一数据集的相邻数据集(位于第一数据集之前且紧邻的历史数据集和位于第一数据集之后且紧邻的候选数据集)中选取第二多媒体数据，因此目标终端可只预加载第一数据集的相邻数据集，以节省处理资源。其中，预加载相邻数据集的具体方式可以是：预加载相邻数据集中的各个多媒体数据，以及每个多媒体数据的起播点的多媒体帧；或者，预加载相邻数据集的具体方式可以是：预加载相邻数据集中的候选多媒体数据，以及各个候选多媒体数据中与用户偏好相匹配的起播点的多媒体帧，以节省处理资源。
在确定多媒体推荐列表后，目标终端还可获取目标用户关于第一多媒体数据的偏好衡量值，该偏好衡量值用于指示目标用户对第一多媒体数据的偏好程度。在一种实施方式中，目标终端可在第一多媒体数据的播放过程中，输出询问信息，以询问目标用户是否喜欢第一多媒体数据，从而根据目标用户输入的响应信息来确定偏好衡量值。另一种实施方式中，目标终端可以在第一多媒体数据被切换时，获取该偏好衡量值；此情况下，目标终端可确定第一多媒体数据的被播放时长，将被播放时长作为偏好衡量值；或者按照被播放时长和偏好程度成正比的关系，确定目标用户关于第一多媒体数据的偏好衡量值。
在得到偏好衡量值后，目标终端可根据偏好衡量值和第一多媒体数据所属的第一数据集的数据标签，更新目标用户的用户偏好画像。若偏好衡量值大于或等于衡量阈值，则可将第一多媒体数据的数据标签作为新的第一偏好标签添加至目标用户的用户偏好画像中，以更新用户偏好画像。若偏好衡量值小于衡量阈值，则可在用户偏好画像查找与第一多媒体数据的数据标签相匹配的第一偏好标签，并删除查找到的第一偏好标签以更新用户偏好画像。然后，可根据更新后的用户偏好画像对多媒体推荐列表中的全部或部分候选数据集进行更新处理。在一种可能的实现方式中，可根据更新后的用户偏好画像，在多媒体推荐列表中的全部或部分候选数据集中查找无效候选数据集，所谓的无效候选数据集是指存在至少一个多媒体数据的数据标签和更新后的用户偏好画像不匹配的候选数据集。在多媒体推荐列表中删除无效候选数据集，以实现多媒体推荐列表的更新处理。
S402，当存在媒体切换操作的情况下，基于第二多媒体数据的目标起播点，从第一多媒体数据切换至第二多媒体数据中处于目标起播点的多媒体帧进行播放。
其中，第二多媒体数据可以是目标音乐或目标视频，目标起播点是P个候选起播点中的其中一个候选起播点；该P个候选起播点可以是根据目标用户的用户偏好画像和第二多媒体数据的热点信息中的一种或多种信息预先配置的。在一种可能的实现方式中，P个候选起播点的配置方式可包括以下至少一种：
配置方式一：第二多媒体数据包括多个起播点，每个起播点具有一个标签信息，那么目标终端可计算用户偏好画像和每个起播点的标签信息之间的匹配度，得到计算结果；其次，可从计算机结果中选取大于匹配阈值的P个目标匹配度，或者从计算结果中按照匹配度从大到小的顺序，依次选取P个目标匹配度。然后，可将每个目标匹配度所对应的起播点作为候选起播点。在此配置方式下，目标起播点的选取方式可包括以下任一种：
在一种实施方式中，可从P个候选起播点中选取时间最早的候选起播点作为目标起播点；即此实施方式下，目标起播点是P个候选起播点中的第一个候选起播点。另一种实施方式中，可从P个候选起播点中选取最大匹配度对应的候选起播点作为目标起播点；即此实施方式下，目标起播点是P个候选起播点中与用户偏好画像的匹配度最大的候选起播点。另一种实施方式中，还可获取P个候选起播点中的每个候选起播点的热度值(用于反映候选起播点处的多媒体帧的受欢迎程度)，并从P个候选起播点中选取最大热度值的候选起播点作为目标起播点；即此实施方式下，目标起播点是P个候选起播点中最具热度的候选起播点。其中，任一起播点的热度值可与该任一候选起播点处的多媒体帧的历史播放次数或历史播放频率成正比，该历史播放次数是指除目标用户以外的其他用户历史播放该任一候选起播点处的多媒体帧的次数。应理解的是，本申请实施例只是示例性地列举了几种从P个候选起播点中选取目标起播点的具体实施方式，并非穷举。例如，在其他实施例中，目标终端还可通过预设权重对匹配度和热度值进行加权求和的方式，求取每个候选起播点的播放合理度衡量值，从而根据每个候选起播点的播放合理度衡量值，从P个候选起播点中选取目标起播点，等等。
配置方式二：第二多媒体数据的热点信息可用于指示第二多媒体数据中具有较高热度值的多媒体帧；那么目标终端可将该热点信息所指示的各个多媒体帧所处的时间点作为P个候选起播点。在此配置方式下，目标起播点的选取方式可包括以下任一种：从P个候选起播点中选取时间最早的候选起播点作为目标起播点。或者，进一步结合用户偏好画像，从P个候选起播点中选取目标起播点；例如，可计算用户偏好画像和各个候选起播点的标签信息之间的匹配度，然后从P个候选起播点中选取最大匹配度的候选起播点作为目标起播点。
配置方式三：计算用户偏好画像和每个起播点的标签信息之间的匹配度，得到起播点的第一推荐分值。以及根据热点信息为每个起播点进行评分，得到每个起播点的第二推荐分值；评分规则可以是：针对任一起播点，若该起播点处的多媒体帧属于热点信息所指示的多媒体帧，则该任一起播点的第二推荐分值为有效分值(如“0.5”“1”等)，否则，则该任一起播点的第二推荐分值为无效分值(如“0”)。然后，分别对每个起播点的第一推荐分值和第二推荐分值进行加权求和，得到每个起播点的目标推荐分值。最后，可选取目标推荐分值大于分值阈值的P个起播点作为P个候选起播点，或者按照目标推荐分值从大到小的顺序，依次选取P个目标推荐分值，并将被选取的各个目标推荐分值对应的起播点作为候选起播点。
在此配置方式下，目标起播点的选取方式可包括以下任一种：从P个候选起播点中选取时间最早的候选起播点作为目标起播点。或者，从P个候选起播点中选取第一推荐分值最大的候选起播点作为目标起播点，即此情况下，目标起播点是P个候选起播点中与用户偏好画像的匹配度最大的候选起播点。又或者，从P个候选起播点中选取第二推荐分值最大的候选起播点作为目标起播点，即此情况下，目标起播点是P个候选起播点中最具热度的候选起播点。
在一种可能的实现中，当第二多媒体数据是目标视频时，目标视频中处于目标起播点的多媒体帧为目标图像帧。此实施方式下，目标终端在检测到存在媒体切换操作后，可先播放切换动画；并在切换动画播放结束后，基于第二多媒体数据的目标起播点，开始播放第二多媒体数据。其中，切换动画可以是将目标图像帧和第一多媒体数据的当前图像帧(检测到媒体切换操作时播放的图像帧)，沿着目标方向移动的动画。目标图像帧或者当前图像帧的位移距离为W，W＝目标终端的屏幕宽度(目标终端处于横屏状态时)，或者W＝目标终端的屏幕高度(目标终端处于竖屏状态时)。对于横屏图像帧(即水平方向上的像素点多于竖直方向上的像素点的图像帧)，当目标终端能全屏显示该横屏图像帧时，可认为目标终端处于横屏状态，当目标终端无法全屏显示该横屏图像帧时，可认为目标终端处于竖屏状态。
通过切换动画可实现在终端屏幕中逐渐显示目标图像帧，直至目标图像帧被完整显示在终端屏幕后，切换动画结束播放。其中，目标方向可以根据具体的媒体切换操作确定，如媒体切换操作是通过从左往右滑动输入第一手势的操作，则由于第二多媒体数据是位于第一多媒体数据之后的，因此目标方向可以是从左往右的方向，以直观提示目标用户第二多媒体数据是位于第一多媒体数据之后的；又如媒体切换操作是通过从上往下滑动输入第二手势的操作，则由于第二多媒体数据所处的第二数据集位于第一数据集之前，因此目标方向可以是从上往下的方向，等等。
由前述可知，当第二多媒体数据是目标视频时，目标视频中处于目标起播点的多媒体帧为目标图像帧。若目标图像帧是目标视频中除首帧图像帧以外的图像帧，则考虑到目标用户可能存在想要从首帧图像帧开始播放目标视频，因此目标终端可通过多种方式来同时为目标用户提供目标图像帧和首帧图像帧的播放显示，以丰富多媒体播放逻辑，提升用户粘度。请参见下述描述：
在一种实施方式中，可通过分屏显示的方式来同时为目标用户提供目标图像帧和首帧图像帧的播放显示。当存在媒体切换操作的情况下，可将终端屏幕划分成第一屏幕区域和第二屏幕区域；在第一屏幕区域中，基于目标图像帧开始播放目标视频；在第二屏幕区域中，基于首帧图像帧开始播放目标视频。假设目标视频为上述图3d所示的视频f，则目标终端在第一屏幕区域51中基于目标图像帧播放目标视频，以及在第二屏幕区域52中基于首帧图像帧播放目标视频的示意图可参见图5a所示。应理解的是，图5a只是以左右分屏的方式为例进行说明的，并不对具体的分屏方式进行限定。例如，在其他实施例中，也可采用上下分屏的方式将终端屏幕划分成第一屏幕区域和第二屏幕区域；再如，图5a是采用 左右分屏的方式将终端屏幕等分成第一屏幕区域和第二屏幕区域的，但在其他实施例中，采用左右分屏的方式所划分的第一屏幕区域和第二屏幕区域的区域面积也可以不相同，等等。
通过分屏显示的方式分别基于目标图像帧和首帧图像帧播放目标视频后，目标终端可支持目标用户通过选中其中一个屏幕区域来实现屏幕合并，并在合并后的终端屏幕中根据被选中的屏幕区域所对应的播放逻辑继续播放目标视频。以第一屏幕区域为例，当存在针对第一屏幕区域的选中操作的情况下，合并第一屏幕区域和第二屏幕区域；并在合并后的终端屏幕中，基于参考图像帧继续播放目标视频。其中，参考图像帧是指存在选中操作时，第一屏幕区域中显示的图像帧。例如，在检测到选中操作时，第一屏幕区域中正在显示第38秒的图像帧，那么参考图像帧便为第38秒的图像帧，目标终端便可在合并后的终端屏幕中继续播放位于第38秒后的各个图像帧，如图5b所示。
另一种实施方式中，可通过视频子页面显示的方式来同时为目标用户提供目标图像帧和首帧图像帧的播放显示。当存在媒体切换操作的情况下，在终端屏幕中输出视频播放界面，并在视频播放界面中以首帧图像帧为播放起始点，播放目标视频；在视频播放界面上输出视频子页面53，并在视频子页面53中显示目标图像帧，或者在视频子页面中以目标图像帧为播放起始点，播放目标视频。其中，视频子页面是指独立于视频播放界面的界面，即视频子页面可以理解成一个悬浮在视频播放界面上的子窗口(或称作浮窗)。仍假设目标视频为上述图3d所示的视频f，则目标终端在视频播放界面基于首帧图像帧播放目标视频，并在视频子页面显示或播放目标图像帧的示意图可参见图5c所示。
通过视频子页面显示或播放目标图像帧之后，目标终端还可支持目标用户通过对该视频子页面执行触发操作(如点击操作、按压操作、隔空手势操作等)，触发目标终端按照视频子页面的播放逻辑，全屏播放继续目标视频。其中，通过在视频子页面固定显示目标图像帧的方式，可节省处理资源；通过在视频子页面基于目标图像帧开始播放目标视频的方式，可实现通过视频子页面为目标用户显示更多的图像帧，来向目标用户输出更多的视频信息，从而吸引目标用户触发视频子页面。
相应的，当视频子页面被触发时，在视频播放界面中将第一当前图像帧切换至第二当前图像帧，并继续显示目标视频中位于第二当前图像帧之后的各图像帧。其中，第一当前图像帧是指在视频子页面被触发时，在视频播放界面中显示的图像帧；第二当前图像帧是指在视频子页面被触发时，在视频子页面中显示的图像帧。应理解的是，若在视频子页面被触发前，该视频子页面中是一直固定显示目标图像帧的，则第二当前图像帧便为目标图像帧；若在视频子页面被触发前，该视频子页面中是基于目标图像帧开始播放目标视频的，即视频子页面中的图像帧在发生变化，则第二当前图像帧可能是目标图像帧(在显示目标图像帧时触发的视频子页面)，也可能是位于目标图像帧之后的某一图像帧(在播放了目标图像帧后，触发的视频子页面)。
举例来说，承接图5c所示的例子：目标视频为上述图3d所示的视频f，目标起播点为视频f中的第36秒。针对在视频子页面中一直固定显示目标图像帧的情况：在输出视频子页面后，可一直固定在视频子页面中显示第36秒的图像帧；在视频子页面被触发时，若视频播放界面中正在显示第15秒的图像帧，则第一当前图像帧便为第15秒的图像帧，第二当前图像帧仍为第36秒的图像帧；那么，目标终端便可在视频播放界面中将第15秒的图像帧切换至第36秒的图像帧，并继续播放位于第36秒后的各个图像帧，如图5d所示。针对在视频子页面中基于目标图像帧开始播放目标视频的情况，在输出视频子页面后，可在视频子页面中从第36秒开始播放目标视频。若在视频子页面被触发时，视频播放界面中正在显示第15秒的图像帧，则第一当前图像帧便为第15秒的图像帧，视频子页面正在显示51秒的图像帧，即第二当前图像帧为第51秒的图像帧；那么，目标终端便可在视频播放界面中将第15秒的图像帧切换至第51秒的图像帧，并继续播放位于第51秒后的各个图像帧，如图5e所示。
还需说明的是，在其他实施例中，由于第二当前图像帧已在视频子页面中进行显示；因此当视频子页面被触发时，也可在视频播放界面中将第一当前图像帧切换至第二当前图像帧的后一帧图像帧，并继续显示目标视频中位于该后一图像帧后的各图像帧。也就是说，在其他实施例中，目标终端也可支持在视频子页面被触发后，全屏不显示第二当前图像帧，而是接着第二当前图像帧播放目标视频。
S403，在终端屏幕中显示第二多媒体数据的播放进度轴，该播放进度轴中包括各个时间点所对应的播放进度位置。
S404，在播放进度轴的目标播放进度位置处显示进度标记元素。
其中，目标播放进度位置是指播放进度轴中与目标起播点对应的播放进度位置。在一种实施方式中，可在显示播放进度轴的同时，在目标播放进度位置处显示进度标记元素；也就是说，在从第一多媒体数据切换至第二多媒体数据的同时，进度标记元素被显示在目标播放进度位置处。另一种实施方式中，可先在播放进度轴的默认播放进度位置处显示进度标记元素，默认播放进度位置是指播放进度轴中与第一个时间点对应的播放进度位置；然后可控制进度标记元素从默认播放进度位置，移动至播放进度轴的目标播放进度位置，以在目标播放进度位置处显示进度标记元素；通过此实施方式来显示进度标记元素，可实现进度标记元素的跳转动画，增强趣味性，该跳转动画的持续时长可为0.2秒、0.1秒等。其中，进度标记元素的具体样式可根据业务需求设置，例如小圆点、三角形、五角星，等等；以进度标记元素54的样式为小圆点为例，控制进度标记元素54从默认播放进度位置移动至播放进度轴的目标播放进度位置的示意图可参见图5f所示。
在一种可能的实施方式中，目标终端可读取第二多媒体数据的预设播放时长，确定预设播放时长后，可与播放进度轴进行关联，来确定播放进度轴上的进度标记元素的位移距离与时间点的对应关系。在确定目标起播点后，可根据该对应关系和目标起播点，确定目标播放进度位置，从而实现在显示播放进度轴后，将进度标记元素显示在目标播放进度位 置处。在进度标记元素被显示在目标播放进度位置后，该进度标记元素可随着第二多媒体数据的播放进度自动移动，直到第二多媒体数据完整播放完毕。
需说明的是：①本申请实施例并不限定S403-S404与S402的执行顺序；例如，S403-S404可以是在S402之后执行的，也可以是在S402之前执行的，还可以是和S402同时执行的，对此不做限制。②若第一多媒体数据和第二多媒体数据是视频播放应用中的视频，则目标终端可采用横屏模式来播放第一多媒体数据和第二多媒体数据，以扩宽第一多媒体数据和第二多媒体数据中的各个图像帧的显示范围。并且，对于视频播放应用中除第一多媒体数据和第二多媒体数据外，其他的各个视频均可被采用横屏模式播放。也就是说，视频播放应用中的任一视频被触发播放时，是采用横屏模式播放所任一视频的；此情况下的视频播放应用的播放原理大致如下：
目标用户打开视频播放应用，即可处于横向全屏视频播放状态(即横屏状态)，无需手动切换。在为目标用户播放某个视频时，可根据目标用户的用户偏好画像设置该视频的起播点，并基于该起播点播放该视频。目标用户可以在处于横向全屏的终端屏幕中通过垂直方向(即上下方向)的滑动的第二交互操作来实现视频集(即数据集)的切换，当用户在某一个视频集的视频A下产生了对该视频集的持续观看意愿，则可以继续观看该视频A，也可通过输入第一交互操作实现在该视频集中进行其他视频的切换。每次视频切换时，均可更新目标用户的用户偏好画像，例如根据目标用户的多媒体历史播放记录获取相关偏好标签如“演员A”“谍战”，则会根据该偏好标签检索替换下一个视频，并可根据用户偏好画像中的偏好标签“演员A”将下一个视频的起播点调整到包含该演员A的重要情节的图像帧的时间点。
S405，在第二多媒体数据的播放过程中，当存在目标触发操作的情况下，从第二多媒体数据中的第一多媒体帧切换播放新起播点的多媒体帧。
需说明的是，S405的实施方式可参见上述方法实施例中的S203的相关描述，在此不再赘述。
本申请实施例在播放第一多媒体数据的过程中，若存在媒体切换操作，则可基于第二多媒体数据的目标起播点，开始播放第二多媒体数据。由于目标起播点是根据目标用户的用户偏好画像和热点信息中的至少一项信息确定的，因此目标起播点处的多媒体帧可在较大程度上满足目标用户的兴趣偏好，那么通过将目标起播点作为起始播放点来播放第二多媒体数据，可在较大程度上提升第二多媒体数据对于目标用户的吸引力，使得目标用户更愿意继续播放第二多媒体数据，从而提升第二多媒体数据的用户粘度。另外，在第二多媒体数据的播放过程中，若存在目标触发操作，则还可通过定位切换播放点的方式，自动从第一多媒体帧快速切换至可满足目标用户的兴趣偏好的多媒体帧(即新起播点的多媒体帧)，从而进一步提升第二多媒体数据对于目标用户的吸引力，提升用户粘度；且无需目标用户通过反复拖动进度条来找到下一个感兴趣的多媒体帧，可有效提升便捷性。由于整个过程无需目标用户手动查找并播放感兴趣的数据，可有效提升多媒体数据的播放效率；并且还 可减少播放目标用户不感兴趣的无效多媒体帧，从而节省处理资源以及有效提升第二多媒体数据的播放有效性。
基于图2和图4所示的方法实施例的相关描述，本申请实施例还提出了如图6a所示的多媒体播放方法；该多媒体播放方法可由上述所提及的目标终端执行，或者由目标终端和服务器共同执行。为便于阐述，本申请实施例主要以目标终端执行该多媒体播放方法为例进行说明；参加图6a所示，该多媒体播放方法可包括以下S601-S602：
S601，播放第一多媒体数据。
S602，当存在媒体切换操作的情况下，基于第二多媒体数据的目标起播点，从第一多媒体数据切换至第二多媒体数据中处于目标起播点的多媒体帧进行播放。
其中，目标起播点是根据以下至少一种信息确定的：目标用户的用户偏好画像和第二多媒体数据的热点信息。在一种实施方式中，第二多媒体数据包括多个起播点，每个起播点具有一个标签信息；则目标终端可计算用户偏好画像和每个起播点的标签信息之间的匹配度，得到计算结果。然后，将计算机结果中的最大匹配度所对应的起播点作为目标起播点；或者，也可根据计算机结果选取P个候选起播点，再从P个候选起播点中选取目标起播点，具体选取方式可参见前述方法实施例中的S402的相关描述。也就是说，此实施方式下，目标起播点是根据目标用户的用户偏好画像确定的。
另一种实施方式中，第二多媒体数据的热点信息可用于指示第二多媒体数据中具有较高热度值的多媒体帧；那么目标终端可根据热点信息将具有最高热度值的多媒体帧所处的时间点作为目标起播点。或者，目标终端可将该热点信息所指示的各个多媒体帧所处的时间点作为P个候选起播点，然后从P个候选起播点中选取目标起播点，具体选取方式可参见前述方法实施例中的S402的相关描述。也就是说，此实施方式下，目标起播点是根据第二多媒体数据的热点信息。
另一种实施方式中，计算用户偏好画像和每个起播点的标签信息之间的匹配度，得到起播点的第一推荐分值；以及根据热点信息为每个起播点进行评分，得到每个起播点的第二推荐分值。然后，分别对每个起播点的第一推荐分值和第二推荐分值进行加权求和，得到每个起播点的目标推荐分值。最后，可选取目标推荐分值最大的起播点作为目标起播点。或者，选取目标推荐分值大于分值阈值的P个起播点作为P个候选起播点，然后从P个候选起播点中选取目标起播点，具体选取方式可参见前述方法实施例中的S402的相关描述。也就是说，此实施方式下，目标起播点是根据第二多媒体数据的热点信息和目标用户的用户偏好画像共同确定的。
需要说明的是，①本申请实施例中的S601和S602针对第一多媒体数据和第二多媒体数据，所采用的具体播放方式可参见上述方法实施例中的S201-S202和S401-S402的相关描述，在此不再赘述。②参见前述方法实施例的相关描述可知，本申请实施例所提及的第一多媒体数据可以是基于第一起播点开始播放的，第二多媒体数据是基于目标起播点开始 播放的；那么同理，目标终端针对除第一多媒体数据和第二多媒体数据的其他多媒体数据，也可基于某个起播点开始播放。也就是说，目标终端针对任一多媒体数据，当不存在媒体切换操作的情况下，也可以根据目标用户的用户偏好画像和任一多媒体数据的热点信息中的一种或多种信息，确定任一多媒体数据的起播点，并基于确定的起播点开始依次连续播放任一多媒体数据。
本申请实施例在播放第一多媒体数据的过程中，若存在媒体切换操作，则可基于第二多媒体数据的目标起播点，从第一多媒体数据切换至第二多媒体数据中处于目标起播点的多媒体帧进行播放。由于目标起播点是根据目标用户的用户偏好画像和第二多媒体数据的热点信息中的至少一种信息确定的，因此目标起播点处的多媒体帧可在较大程度上满足目标用户的兴趣偏好或引起目标用户的兴趣，那么通过将目标起播点作为起始播放点来播放第二多媒体数据，便可在较大程度上提升第二多媒体数据对于目标用户的吸引力，使得目标用户更愿意继续播放第二多媒体数据，从而提升第二多媒体数据的用户粘度以及第二多媒体数据的播放转化率。由于整个过程无需目标用户通过反复拖动进度条来手动查找并播放可引起自己兴趣的多媒体帧，不仅可有效提升便捷性以及多媒体数据的播放效率；还可减少播放目标用户不感兴趣的无效多媒体帧，从而节省处理资源以及有效提升第二多媒体数据的播放有效性。
上述图2、图4和图6a所示的多媒体播放方法主要是以目标终端作为执行主体进行说明的，基于上述图2、图4和图6a所示的实施例描述，本申请实施例还提出了如图6b所示的多媒体播放方法；在本申请实施例中，主要以目标终端和服务器共同执行该多媒体播放方法为例进行说明。该多媒体播放方法可包括如下步骤：
首先，目标终端可在目标用户首次使用目标应用(如视频播放应用或音乐播放应用)获取目标用户的用户信息，如通过社交账号(如OpenID)获取的社交信息、在目标用户主动授权后获取的目标终端的终端信息(如终端厂商、型号(设备层)等)、周围环境信息(如目标用户的当前位置、常住位置等)、在目标用户授权后获取的行为轨迹信息、通过共享网络(如网络热点、WIFI(无线保真))以及用户通讯录所获取的用户关系、通过应用安装记录所确定的已安装应用的应用信息，等等。然后可根据用户信息预测目标用户的偏好，从而得到初始的用户偏好画像，不同的用户信息可对应不同的预测方式。例如，针对周围环境信息而言，目标终端可根据目标用户的当前位置或常住位置，通过大数据分析确定出与目标用户属于同一区域内的其他用户，并将其他用户的偏好标签添加至初始的用户偏好画像中。又如，针对通过共享网络的用户关系而言，可根据该用户关系确定与目标用户常用同一网络的关联用户，并将其他用户的偏好标签添加至初始的用户偏好画像中。再如，针对应用信息而言，可根据应用信息确定已安装应用，并根据已安装应用的应用功能确定目标用户的偏好标签；若已安装应用常推送探险类的视频，则可确定目标用户的偏好标签为“爱冒险”，若已安装应用常推送××明星的新闻，则可确定目标用户的偏好标签为“××明星”，等等。
然后，目标终端可将目标用户的初始的用户偏好画像发送给服务器，由服务器根据用户偏好画像和多媒体数据的数据标签之间的映射关系，确定与目标用户的初始的用户偏好画像具有映射关系的数据标签，并将确定的数据标签所指示的多媒体数据的数据标识(设多媒体A)和目标用户的初始的用户偏好画像(设用户偏好画像A)关联存储至下述表1中：
表1
用户偏好画像A 用户偏好画像B 用户偏好画像C 用户偏好画像…
偏好标签x… 偏好标签w… 偏好标签r… 偏好标签p…
多媒体A 多媒体B 多媒体C 多媒体…
当目标用户存在多媒体数据的播放需求时，目标终端可请求服务器基于该用户偏好画像通过推荐引擎进行多媒体推荐播放。例如，服务器可将表1中的多媒体A对应的多媒体数据作为第一多媒体数据，下发至目标终端。在第一多媒体数据的播放过程中，服务器的推荐引擎还可从目标用户的用户偏好画像中获取相关偏好标签(如第一偏好标签)，并在数据库中根据相关偏好标签检索相关的匹配多媒体数据，确定匹配多媒体数据后，再通过用户偏好画像中的第二偏好标签二次检索各个匹配多媒体数据中相匹配的起播点。如果推荐引擎两次检索匹配到用户偏好画像，则将具有匹配项的全部内容进行权重计算，从而根据权重计算结果确定出候选多媒体数据，并将各个候选多媒体数据所处的候选数据集发送目标终端。目标终端接收到各个候选数据集后，可将其添加至多媒体播放列表中，并根据第一多媒体数据在多媒体播放列表中的排列位置，自动预加载相邻多媒体数据集中的候选多媒体数据，以及相匹配的起播点的多媒体帧。
在播放第一多媒体数据的过程中，可获取目标用户关于第一多媒体数据的偏好衡量值，从而根据偏好衡量值来更新用户偏好画像。另外，还可检测目标用户是否喜欢第一多媒体数据。若喜欢第一多媒体数据，则继续播放第一多媒体数据；若不喜欢第一多媒体数据，此时可执行多媒体数据的切换，以及更新多媒体推荐列表的操作。另外，目标用户也可通过输入媒体切换操作(如输入第一手势或第二手势的操作)来实现多媒体切换；在目标用户通过输入第一手势或第二手势进行多媒体切换时，目标终端可立即从预加载的数据集中根据具体的交互操作获取第二多媒体数据，并将预加载的第二多媒体数据中的目标起播点的多媒体帧做承接播放。需说明的是，若目标终端只有一个播放器(Video Player)，且只接收一个Video Player Controller(播放器控制器)，则目标终端可Video Player Controller来绑定要播放的第二多媒体数据的缓存地址，从而实现第二多媒体数据的切换播放。与第一多媒体数据类似，在目标用户在播放了第二多媒体数据后，目标终端可根据目标用户关于第二多媒体数据的偏好程度进行兴趣分类，分类后的兴趣数据会对应预设好的偏好标签；然后，目标终端可将对应成功后的偏好标签发送给服务器，由服务器将该偏好标签更新到 用户偏好画像中。可理解的是：目标用户播放的多媒体数据的数量越多，则目标用户的用户偏好画像的偏好标签就越丰富，从而使得推荐结果也会越准确。
由此可见，通过帮助目标用户在播放多媒体数据，尤其是预设播放时长较长的多媒体数据时，通过根据用户偏好画像来调整起播点，从而进行多媒体数据的播放，可来降低目标用户的决策成本。并且，通过上下滑动、左右滑动等极简手势与即时播放，可有效降低多媒体数据的预览成本，从而提升用户粘度。

根据本申请的另一个实施例，图7所示的多媒体播放装置中的各个单元可以分别或全部合并为一个或若干个另外的单元来构成，或者其中的某个(些)单元还可以再拆分为功能上更小的多个单元来构成，这可以实现同样的操作，而不影响本申请的实施例的技术效果的实现。上述单元是基于逻辑功能划分的，在实际应用中，一个单元的功能也可以由多个单元来实现，或者多个单元的功能由一个单元实现。在本申请的其它实施例中，基于多媒体播放装置也可以包括其它单元，在实际应用中，这些功能也可以由其它单元协助实现，并且可以由多个单元协作实现。
根据本申请的另一个实施例，可以通过在包括中央处理单元(CPU)、随机存取存储介质(RAM)、只读存储介质(ROM)等处理元件和存储元件的例如计算机的通用计算设备上运行能够执行如图2或图4中所示的相应方法所涉及的各步骤的计算机程序(包括程序代码)，来构造如图7中所示的多媒体播放装置设备，以及来实现本申请实施例的多媒体播放方法。所述计算机程序可以记载于例如计算机可读记录介质上，并通过计算机可读记录介质装载于上述计算设备中，并在其中运行。
本申请实施例可根据实际需求灵活地为第二多媒体数据预先配置P个候选起播点，使得在播放第一多媒体数据的过程中，在存在媒体切换操作的情况下，可灵活地从P个候选起播点中选取一个目标起播点，并基于第二多媒体数据的目标起播点，从第一多媒体数据切换至第二多媒体数据中处于目标起播点的多媒体帧进行播放，可有效提升多媒体播放的灵活性。并且，在第二多媒体数据的播放过程中，在存在目标触发操作的情况下，还可通过定位切换播放点的方式，自动从第一多媒体帧快速切换至满足实际需求的另一多媒体帧(即新起播点的多媒体帧)，从而减少播放无效多媒体帧(未满足实际需求的多媒体帧)；这样不仅可进一步提升多媒体播放的灵活性，还可有效节省处理资源，有效提升第二多媒体数据的播放有效性和播放效率。
基于上述图6a所示的多媒体播放方法的相关实施例的描述，本申请实施例还提出了一种多媒体播放装置，该多媒体播放装置可以是运行于目标终端中的一个计算机程序(包括程序代码)。该多媒体播放装置可以执行图6a所示的多媒体播放方法；请参见图8，所述多媒体播放装置可以运行如下单元：

本申请实施例在播放第一多媒体数据的过程中，若存在媒体切换操作，则可基于第二多媒体数据的目标起播点，从第一多媒体数据切换至第二多媒体数据中处于目标起播点的多媒体帧进行播放。由于目标起播点是根据目标用户的用户偏好画像和第二多媒体数据的热点信息中的至少一种信息确定的，因此目标起播点处的多媒体帧可在较大程度上满足目标用户的兴趣偏好或引起目标用户的兴趣，那么通过将目标起播点作为起始播放点来播放第二多媒体数据，便可在较大程度上提升第二多媒体数据对于目标用户的吸引力，使得目标用户更愿意继续播放第二多媒体数据，从而提升第二多媒体数据的用户粘度以及第二多媒体数据的播放转化率。由于整个过程无需目标用户通过反复拖动进度条来手动查找并播放可引起自己兴趣的多媒体帧，不仅可有效提升便捷性以及多媒体数据的播放效率；还可减少播放目标用户不感兴趣的无效多媒体帧，从而节省处理资源以及有效提升第二多媒体数据的播放有效性。

本申请实施例可根据实际需求灵活地为第二多媒体数据预先配置P个候选起播点，使得在播放第一多媒体数据的过程中，在存在媒体切换操作的情况下，可灵活地从P个候选起播点中选取一个目标起播点，并基于第二多媒体数据的目标起播点，从第一多媒体数据切换至第二多媒体数据中处于目标起播点的多媒体帧进行播放，可有效提升多媒体播放的灵活性。并且，在第二多媒体数据的播放过程中，在存在目标触发操作的情况下，还可通过定位切换播放点的方式，自动从第一多媒体帧快速切换至满足实际需求的另一多媒体帧(即新起播点的多媒体帧)，从而减少播放无效多媒体帧(未满足实际需求的多媒体帧)；这样不仅可进一步提升多媒体播放的灵活性，还可有效节省处理资源，有效提升第二多媒体数据的播放有效性和播放效率。
