参照图1，本申请实施例首先提供了一种在智能电视中播放3D片源的方法，该方法可以包括以下步骤：
S101：接收到播放指定片源的请求时，判断所述指定片源是否为3D片源；
在本申请实施例中，可以在轮播应用中包含一个3D命令发送模块，当用户想要收看某3D片源时，可以向轮播应用发送播放该3D片源的指令。对于轮播应用而言，在收到播放某片源的指令时，首先可以判断一下，该片源是否为3D片源，如果不是3D片源，则可以按照正常的2D视频播放流程，向底层的播放模块发送命令，指示播放模块进行播放即可。但是，如果是一个3D模块，则可以进入步骤S102进行后续的处理。其中，在判断一个片源是否为3D片源时，可以有多种方式，例如，在一种实现方式下，由于各种片源一般都是由智能电视的服务器预先收集并提供的，并且，服务器端一般会将2D片源以及3D片源存储在不同的路径下，因此，轮播应用在收到一个播放当前指定片源的请求 后，可以直接根据指定片源的存储路径来判断其是否是一个3D片源。具体的，由于服务器一般会为各个片源提供播放地址，该播放地址中一般会包含片源在服务器中的存储路径信息，因此，可以根据当前指定片源的播放地址，提取出片源的存储路径，然后根据该路径确定当前待播放的片源是否为3D片源，例如，如果提取到的存储路径信息与预先获知的3D片源的存储路径相匹配，则判定指定片源为3D片源。
S102：如果是，则确定该指定片源的合成方式，并根据该指定片源的合成方式修改该指定片源的标志位信息，其中，修改后的标志位信息用于指示该片源为3D片源，以及该3D片源的合成方式；
如果判断出当前待播放的片源是一个3D片源，则可以自动判断该3D片源对应的合成方式。其中，对于一个3D片源而言，其采用的合成方式是与拍摄方式相关的，例如，如果拍摄的时候采用的是两台在左右方向上存在一定视差的摄像机拍摄的，则在合成时，就需要将两台摄像机拍摄到的图像进行左右合成；相应的，如果拍摄的时候采用的是两台在上下方向上存在一定视差的摄像机拍摄的，则在合成时，就需要将两台摄像机拍摄到的图像进行上下合成。在本申请实施例中，在服务器采集3D片源的过程中，就可以获取到3D片源的合成方式信息，例如，某3D片源是某作者上传到服务器上的，则在上传3D片源时，就可以要求上传者提供合成方式信息，以便服务器进行标记。或者，服务器端也可以预先为不同的合成方式创建不同的文件夹等，并要求上传者将其3D片源按照合成方式上传到对应的文件夹中，这样，可以通过片源所处的具体保存路径，区分出3D片源的合成方式是左右合成还是上下合成的。因此，也可以从指定片源的播放地址中提取指定片源的存储路径信息，将提取到的存储路径信息与预先获知的各种合成方式的存储路径相匹配，如果与某种合成方式的存储路径匹配成功，则判定该3D片源为该合成方式。换言之，在用户发出了播放某片源的请求后，不仅可以从片源的播放地址中获知该片源是否为3D片源，还可以进一步获知3D片源的合成方式。
在获知了3D片源的合成方式之后，可以对片源的标志位进行修改。这是本申请实施例中最关键的一步，也就是说，可以预先为各个片源设定一个标志位(可以是一个全局的flag)，在默认状态下，该标志位可以为“0”等默认值， 当用户指定播放某片源，并且在轮播应用判断出属于3D片源，以及合成方式之后，就可以对标志位进行改写。例如，预先定义好左右合成方式的3D片源对应的值为“2”，上下合成方式的3D片源对应的值为“3”，则在判断出一个3D片源属于左右合成方式时，就可以将标志位由“0”修改为“2”，如果判断出一个3D片源属于上下合成方式时，就可以将标志位由“0”修改为“3”。当然，以上描述中具体的数字仅用于举例介绍，不应看作是对本申请实施例保护范围的限制。
S103：接收到底层合成模块发送的轮询请求时，将所述修改后的标志位信息返回给所述底层合成模块，以便所述底层合成模块发现所述标志位信息发生变化时，向播放模块发送播放3D片源的指令，并通知所述播放模块利用修改后的标志位信息对应的合成方式对3D片源进行合成并播放。
在轮播应用进行步骤S101以及S102的判断以及标志位修改等操作的同时，底层的合成模块会不断的向上层应用发送轮询请求，上层应用在修改了标志位之后，就可以将修改事件以及修改后的取值返回给底层合成模块。这样，底层合成模块就可以据此获知是否请求播放3D片源，如果是，还可以直接根据修改后的取值确定出需要使用的合成方式。在确定出需要使用的合成方式之后，还可以向底层的播放模块(例如FRC(Frame Rate Conversion，帧率转换技术))发送播放3D片源的指令，并通知播放模块利用修改后的标志位信息对应的合成方式对3D片源进行合成并播放。
总之，在本申请实施例中，在用户需要播放一个3D片源时，只要选定需要播放的片源即可，不需要再执行手动的选择合成方式的操作，轮播应用可以自行进行判断以及标志位的修改，相应的，底层的合成模块以及播放可以根据标志位修改事件以及修改后的标志位的取值，对3D片源进行合成以及进一步的播放等操作。因此，在播放3D片源的过程中，可以降低用户的操作成本，提高效率。另外还可以避免由于用户的误操作导致的播放错误等现象。
