技术领域
本发明涉及多媒体技术领域，尤其涉及一种播放控制方法和装置。
背景技术
电视频道播放节目时会插播很多广告，影响用户的观看。在播放广告过程中，有的用户希望切换到其他应用中，如切换到看新闻，或切换到其他频道。但切换频道后又容易出现错过之前节目的情况。为了使用户能够控制切换频道的时间，在电视频道的节目播放过程中，有一些电视频道在广告播放时会出现提示倒计时提醒功能(一般是在屏幕的右上角)。这样，用户可以根据广告时间来决定切换到其他应用的时间，在广告倒计时时间结束后再跳回之前看的频道。
目前，多采用画中画技术控制频道的切换。例如，在当前频道播放的画面中，采用小屏显示之前观看的频道的画面。但是画中画技术会影响整体的观感，小屏中的内容也不易看清楚。

实施例1
图1示出根据本发明一实施例的播放控制方法的流程图。如图1所示，该播放控制方法主要包括：
步骤101、根据用户的智能跳回指令，获取所播放的第一内容的标识信息和时间信息；
步骤102、检测用户是否选择从第一内容切换为第二内容，在检测到从所述第一内容切换为第二内容的情况下，执行步骤103；
步骤103、判断所述时间信息是否满足跳回条件，在所述时间信息满足跳回条件的情况下，执行步骤104；
步骤104、根据所述标识信息从所述第二内容跳回继续播放所述第一内容。
在一种可能的实现方式中，所述获取所播放的第一内容的标识信息和时间信息，包括：记录所述第一内容的标识信息；截取所述第一内容中的图像，并识别所截取的图像中的时间信息。
在一种可能的实现方式中所述记录所述第一内容的标识信息，包括：记录播放所述第一内容的频道标识或窗口标识；所述识别所截取的图像中的时间信息，包括：识别所述图像中的广告倒计时的时间。
举例而言，识别所述图像中的广告倒计时的时间，包括：在所述图像的右上角，识别是否存在所述广告倒计时的时间；在时间识别失败的情况下，在所述图像的右侧中部、右下角和左下角识别是否存在所述广告倒计时的时 间；在时间识别失败的情况下，识别所述图像左上角的台标；在台标识别成功的情况下，根据识别出的台标查询广告倒计时位置，并在所述图像上的所述广告倒计时位置识别所述广告倒计时的时间；在台标识别失败的情况下，对所述图像进行全屏识别，以获取所述广告倒计时的时间。目前广告倒计时的时间通常显示在视频的右上角，也有一些显示在图像的其他位置，先识别右上角成功几率高。本示例仅是识别广告倒计时的时间一种识别顺序，也可以按照其他顺序对图像中的广告倒计时的时间进行识别，本发明对此不进行限制。
在一种可能的实现方式中，判断所述时间信息是否满足跳回条件，包括：根据所述广告倒计时的时间，判断所述广告是否播放结束；在所述广告播放结束的情况下，判定为满足所述跳回条件。
举例而言，第一内容可以是当前播放的电视节目、网络视频等，播放过程中可能出现插播广告的情形，影响用户的观看心情、浪费观看时间。用户可以通过遥控器或鼠标等选择智能跳回操作，向播放设备发出智能跳回指令。这时，播放设备例如电视机、电脑、手机等可以记录当前所播放的视频的频道标识(例如频道号、台号、频道名称等)、窗口标识(例如网页窗口的地址或编号等)。然后，播放设备对当前频道或当前窗口插播的广告进行截屏，并识别所截取的图像中的广告倒计时的时间。最后再判断广告倒计时是否结束，如果广告倒计时结束，则满足跳回条件。这种情况下，可以自动跳回，也可以由用户决定是否跳回。
在一种可能的实现方式中，步骤104包括：向所述用户返回所述广告播放结束的提示窗口；在接收到所述用户的确认跳回指令的情况下，根据所述频道标识或窗口标识，将当前频道或当前窗口从所述第二内容跳回继续播放所述第一内容。
具体而言，播放设备可以在当前界面上显示提示窗口，以通知用户第一 内容所播放的广告已经结束，由用户决定是否跳回继续观看第一内容。当然，提示窗口可以显示“频道A广告结束，是否跳回”、“剩余n秒跳回频道A”等类似的提示文字和选择按钮，由用户选择后续操作。
为了方便用户合理规划时间安排，提高用户体验，该播放控制方法中，在将当前频道或当前窗口从所述第一内容切换为所述第二内容后，可以在所述当前频道或当前窗口中显示所述广告当前的倒计时的时间。用户在操作第二内容时，可以知道第一内容中广告的播放剩余时间，从而决定什么时间跳回第一内容所在的频道或窗口。其中，第二内容可以是电视的其他频道，也可以是其他网页窗口。
本实施例，根据播放的第一内容的时间信息，能够判断是否满足跳回条件，如果满足跳回条件，就可以根据第一内容的标识信息从第二内容跳回第一内容，从而在播放过程中能够更合理的控制内容切换，提高用户体验。具体地，在播放视频时插播广告的情况下，采用智能跳回，用户可以在浏览或观看其他内容的情况下，准确且方便的知道先前观看的视频中插播的广告是否结束，从而合理的规划观看时间，提高用户体验。
实施例2
图2示出根据本发明另一实施例的播放控制方法的流程图。本实施例中以电视节目出现广告的场景为例，对本发明的播放控制方法进行说明。如图2所示，该播放控制方法具体可以包括以下步骤：
步骤201、在播放某一视频V1时出现广告，且右上角有倒计时出现。
具体而言，可能是播放视频V1的过程中插播，也可能是播放视频V1开始时的片头广告。播放视频V1的频道界面或网络窗口界面上显示该广告的倒计时。
步骤202、用户按下“智能跳回”。例如，在智能电视***中设置一个功能菜单，比如叫“智能跳回”，当广告正在播放时通过用户可以启动“智能 跳回”功能，比如通过遥控器调出。
步骤203、记录当前频道，截屏，并识别倒计时，设置返回时间。
具体而言，如图3所示，在步骤301中，智能电视***首先记录下播放视频V1的当前的频道号(例如当前台的***编码)，便于之后切换回来。然后在步骤302中，截屏视频V1的当前的画面，对右上角的文字进行识别，提取其中的数字，比如“100”，意为广告还有100秒结束。由此推算出广告结束的时间点，即***自动跳回到当前频道的时间。
为了保险，可以在识别成功之后等例如一秒再识别一次，看所识别的数字是否相应减了一秒，比如是否由100变成了99，以保证识别的倒计时是正确的。
其中，如图3所示，识别倒计时时间可能包括以下步骤：
步骤303a、多数视频的倒计时出现在右上角，故可以先识别右上角的倒计时文字。
步骤303b、若右上角没有文字，则再识别右侧中部、右下角、左下角等有可能出现广告的位置是否有倒计时文字。
若依然没找到，有两种办法：
(1)在步骤303c中，识别左上角的台标，识别出这是哪个台，然后在步骤304中通过联网或者查询本地数据库，查询这个台的广告一般是以什么形式出现在什么位置，并进行识别。
(2)在步骤303c中，若无法识别台标，或者虽然识别了台标但是***中没有存储该台的广告位置，或者虽然存储了该台的广告位置但是实际运行中并未从对应位置识别到相应的信息(有可能该台更改了广告呈现方式)。可采用一种办法是：在步骤305中，从用户启动“智能跳回”功能起例如第1、2、3秒内各截屏一次，通过数字图像处理对截屏的图像进行全屏识别出这三张图片中的不变内容，比如“广告还剩30秒”其中的“广告还剩”“秒”这几 个字是不变的，而其中夹杂的“100”“99”“98”等数字则是有规律递减的，此时也许画面中还有其他的内容也保持不变，可以通过再多截屏几张画面进一步筛选，也可以通过文字识别找出“广告”“还剩”“秒”等字样，达到精确定位识别的功能。然后，在步骤306中可以根据上一步的识别结果设置返回时间，返回时间通常可以根据所识别的广告倒计时来确定，例如广告剩余98秒，可以将返回时间设置为在此时刻的第98秒(或提前几秒)。
步骤204、在屏幕上提示用户已经成功识别了广告倒计时的时间。
步骤205、此时，用户可自由切换到电视的其他应用或频道中。用户切换到其他应用或频道时，可在右上角依然显示一个正在倒计时的数字，让用户合理规划时间安排，提高用户体验。
步骤206、如果***后台检测到达广告结束时间(例如***后台监测到达返回时间)，即执行步骤207自动切换回之前的频道(例如自动跳回预调频道)。此外，也可以弹出一个窗口提示用户广告已经结束，由用户决定是否要切换回之前的频道。
本实施例中，在播放视频时插播广告的情况下，采用智能跳回，用户可以在浏览或观看其他内容的情况下，准确且方便的知道先前观看的视频中插播的广告是否结束，从而合理的规划观看时间，提高用户体验。
