用户在终端设备中登录支持DLNA投屏功能的应用程序(APP)，并进入投屏界面，首先搜索要投射的显示设备，以显示设备为智能电视为例，如图5所示，发起投屏的终端设备和作为被投射对象的电视都需要连接WiFi，终端设备可以搜索到与其处于同一个WiFi网络环境下的电视，并将搜索到的可建立投屏连接的电视设备在界面中列举出来，比如图5中，当前WiFi为MERCURY_6ABC，搜索到了一个电视设备，该电视设备的信息为客厅极光TV(365D)，IP地址为192.168.1.101，用户点击该电视设备后，即可选择要向该设备投射的初始片源。在可连接设备列表中，每个电视设备都有一个选择控件，如图5中小方块，通过触控这个选择控件，可以选中可连接设备列表其中的一个或多个设备进行投屏。
图6示出了一种终端设备投射初始片源的界面，界面中可以包括初始片源的缩略图、片源名称、评分、风格和简介等与片源信息，初始片源的缩略图可以是从片源中截取的某一帧图像。界面中还要设有触发投屏请求的控件，比如图6中的“电视播放”，用户点击“电视播放”后，即生成投屏请求，投屏请求中携带有电视设备信息等信息，从而实现向目标投射对象的电视端请求投射该初始片源。需要说明的是，终端设备中发起投屏请求的方式、界面操作和界面显示的内容不限于本实施例及附图所示，具体与不同型号终端设备和应用程序有关。
电视端配置的DLNA协议栈响应于投屏请求后，向电视端中的媒体中心应用发送第一指示信息，媒体中心应用根据第一指示信息，在电视的显示器上显示提示弹窗。图7示出一种提示弹窗，提示弹窗用于询问用户是否允许与终端设备连接并播放推荐片源，比如显示“一台终端设备正在连接你的电视，是否允许连接并播放推荐片源？”，并可以一并显示请求建立连接的终端设备的Mac Address(Media Access Control Address，媒体存取控制位址)，网络中每台设备都有唯一的网络标识即Mac地址，用以确认网络设备的位置。同时在提示弹窗中，可以设置“永久同意”选框，当“永久同意”被勾选并确认后，以后电视接收到投屏请求后会自动允许建立设备连接并同意播放推荐片源，所以不会再显示提示弹窗。提示弹窗中还设置有“同意”选项和“不同意”选项，当用户点击“不同意”，则取消设备连接并销毁提示弹窗，电视继续保持原显示状态；当用户点击“同意”，而没有勾选“永久同意”时，即说明仅允许本次授权连接，后续再接收到投屏请求时还要继续显示提示弹窗。
当用户在提示弹窗中输入允许指令后，接收终端设备发送的初始片源的URI(Uniform Resource Identifier，统一资源标识符)，后续即可根据初始片源的URI播放初始片源。接下来就需要获取推荐片源。电视可以向服务器发送第一指令，服务器响应第一指令后，会搜索一些推荐片源，该推荐片源可以是与初始片源有关的片源，比如属于同一电视剧的不同集，或者是与初始片源同一类型风格的片源，又或者是近期热播的片源、高评分片源等，即将用户可能感兴趣观看的片源推荐给用户。当电视接收到服务器反馈的推荐信息，推荐信息可以包括各个推荐片源的URI，然后即可起播初始片源，初始片源的播放界面如图8所示，即将终端设备推送给的初始片源投屏到电视上进行播放，从而体验大屏观看效果。
为了实现投屏功能的丰富性，在初始片源播放过程中，可以直接用户向用户展示推荐信息列表，方便用户查看推荐片源，并根据感兴趣程度选出某个推荐片源进行起播。在具体实现中，如图9所示，推荐信息列表可以在预设位置进行显示，比如界面底部；推荐信 息列表可以按行进行展示，即包括1行多列，用户通过左右滑动来查看列表中包括的各项推荐片源。
在其他实现中，推荐信息列表可以按列进行展示，即包括多行1列，用户通过上下滑动来查看列表中包括的各项推荐片源；又或者，推荐信息列表可以按网格形式进行展示，即包括多行多列。推荐信息列表的呈现形式不限定，推荐信息列表中可以包括每个推荐片源的缩略图，缩略图底部也可附带该推荐片源的基本信息，基本信息比如是片源名称、对应的集数/期数/部数、主要看点和时长等信息，缩略图关联有跳转控件，以使用户点击某个推荐片源时，触发该推荐片源的跳转控件，则即可将初始片源的播放界面跳转切换至该推荐片源的播放界面。推荐信息列表的显示内容不限于本实施例所述，具体可根据实际UI显示需求进行配置。推荐信息列表占整体显示界面的比例应尽量小，以保证当前初始片源的观看效果。
此外，在初始片源的播放界面中还可设置弹动控件41，弹动控件41用于隐藏或弹出推荐信息列表。当初始片源开始启动播放时，可以默认推荐信息列表处于隐藏状态，这时如图10(a)所示，弹动控件41位于界面底边，初始片源全屏播放；当用户想要查看推荐信息列表时，可以点击弹动控件41，这时弹动控件41按照图10(a)所示的箭头方向展开，使得推荐信息列表的行从下至上逐渐弹出，直至图10(b)所示的显示界面，则推荐信息列表处于显示状态，这时初始片源上推荐信息列表的上部播放；在图10(b)的状态下再点击一次弹动控件41，则弹动控件41按照图10(b)所示的箭头方向复位，使得推荐信息列表的行从上至下逐渐关闭，直至图10(a)所示的隐藏状态。需要说明的是，弹动控件41的配置和控件方式不限于本实施例所述，本实施例示出的是渐变弹动式，还可以采用其他动态效果，比如可参照幻灯片具有的播放效果。弹动控件41可以淡化或虚化显示，以避免影响片源的播放效果。
在实际应用中也可不设置弹动控件41，比如采用一些手势控制，语音控制、遥控器点击/双击界面等形式；或者采用定时显隐，比如在初始片源播放至总时长的一半时自动弹出推荐信息列表，在预设时间内(比如5秒)用户无操作和响应，则自动隐藏推荐信息列表；又或者在初始片源播放结束时自动显示推荐信息列表，让用户选择接下来继续播放哪个推荐片源。总之，推荐信息列表隐藏和显示的控制模式多种多样，可以在电视的“投屏设置”里设定多种推荐信息列表的显隐控制模式，供用户选择和设置，本实施例不再赘述。
图11示出一种投屏控制方法的实施例，该方法由显示设备的控制器250被配置执行，即控制器250为方法的执行主体，该方法包括如下程序步骤：
步骤S10，响应于接收到终端设备发送的投屏请求，控制显示器显示提示弹窗；所述 提示弹窗用于询问用户是否允许与所述终端设备连接并播放推荐片源。
步骤S20，响应于用户输入的允许指令，向服务器发送第一指令。
当用户在提示弹窗中选择“同意”或“永久同意”时，即输入了允许指令，则向服务器发送第一指令，第一指令用于指示服务器获取推荐信息。服务器响应第一指令后，会搜索一些推荐片源，该推荐片源可以是与初始片源有关的片源，比如属于同一电视剧的不同集，或者是与初始片源同一类型风格的片源，又或者是近期热播的片源、高评分片源等，即将用户可能感兴趣观看的片源推荐给用户。
在一种实施例中，当用户输入允许指令后，终端设备会向显示设备发送初始片源的URI。显示设备接收到初始片源的URI后，通过初始片源的URI可以解析初始片源的关键字，关键字可以是片源名称等重要信息。比如初始片源的URI为http://192.168.0.121:38520/ExportContent/Dream Therapy.mp4，则关键字为Dream Therapy。然后根据关键字生成第一指令，或者也可以直接将关键字发送给服务器，然后由服务器根据关键字进行关联性/相似性片源的匹配搜索，得到推荐信息，推荐信息中包括多个推荐片源的URI等所需信息。通过这种方式获得的推荐片源与初始片源的关联性/相似性最高，使得推荐片源能够更贴近用户的观看兴趣和品味，极大地提升了用户体验。
步骤S30，当接收到所述服务器根据所述第一指令发送的推荐信息时，起播与所述投屏请求对应的初始片源。
在一些实施例中，由于全网中片源资源众多，因此服务器根据关键字匹配搜索关联性/相似性片源时，搜索不到的可能性非常低，即便真的没有搜索到，服务器也可以根据优先级选取一些关联性/相似性稍微低一些的片源，或者直接推荐一些高评分、最新上映或是播放量/推荐量/收藏量高的片源，作为推荐片源。需要说明的是，服务器获取推荐片源的方式不限于本实施例所述，这并不影响本方案的实质。
因此，如果遇到服务器返回的推荐信息是空信息的情况，可能是由于服务器工作状态异常，或是服务器与显示设备通信异常等因素导致，这时需要重试，即显示设备重新向服务器发送第一指令，直至服务器返回的推荐信息非空。当推荐信息非空时，说明获取到了有效的推荐片源，即可生成播放指令，所述播放指令用于指示显示器起播初始片源。
步骤S40，响应于切换指令，退出所述初始片源，起播所述推荐信息对应的推荐片源。
在步骤S40进一步的实施例中，在初始片源播放时，检测初始片源的播放进程，当播放进程达到终点时，即初始片源播放结束时，可以自动显示推荐信息列表，供用户选择列表中的一个推荐片源继续播放。
在其他实现方式中，显示设备接收到推荐信息后，根据一定的排序规则对推荐信息中 的所有推荐片源进行排序，然后生成推荐信息列表，排序规则比如是按照与初始片源的关联性或相似性降序排列，或者按照播放量/收藏量/评分等参考因素降序排列，排序规则可根据实际情况进行设置，本实施例不限定。当初始片源播放结束后，起播推荐信息列表中排在首位的推荐片源，之后再用户没有进行操作和响应的情况下，可以按照推荐列表的排序依次播放列表中的推荐片源。
在其他实现方式中，可以在初始片源播放未结束的过程中，供用户切换片源，响应于接收到用户输入的显示指令，在当前播放界面中显示推荐信息列表，这里所述的显示指令可以是对弹动控件41的操作，或是手势控制指令，遥控器中的点击/双击界面等形式，也可以是语音形式的指令，比如用户通过语音输入“显示推荐信息列表”。在推荐信息列表显示时，用户输入对列表中某个推荐片源的点击操作，即可触发跳转控件并生成切换指令，即可退出初始片源的播放，跳转至被选中的推荐片源继续播放，从而在初始片源播放过程中实现片源的切换。
本申请中适用于终端设备中的应用程序支持DLNA功能，显示设备中具有对应的DLNA协议栈，通过DLNA协议栈实现播放终端推送的初始片源的流程控制。当终端设备发起投屏请求时，提示弹窗会询问用户是否允许与终端设备连接并播放推荐片源，当用户允许终端与显示设备连接时，那么就一并允许了播放推荐片源，拿什么向服务器发送第一指令，服务器响应于第一指令会搜索一些推荐信息，推荐信息可以包括与初始片源有关的相关推荐片源，比如初始片源是电视剧A的第1集，那么推荐片源就可以是电视剧A的第2集～第N集，当推荐信息获取之后，可以播放终端推送的初始片源，在初始片源播放过程中或者播放结束时收到切换指令，则退出初始片源的播放，起播推荐片源。本申请不仅能播放初始片源，还能播放服务器推送的推荐片源，使得投屏不再仅依赖于用户不断的请求投射片源，改进投屏功能，提升了用户体验。
在其他可能的实施例中，图12中示例性示出了一种投屏控制方法的交互流程图，包括终端设备、显示设备200和服务器300，显示设备分别与终端设备和服务器通信连接，终端设备包括但不限于智能手机、平板电脑和笔记本电脑等移动终端100B，显示设备可以是电视、影院屏幕等大屏设备，显示设备和终端设备之间支持DLNA协议，并在同一WiFi网络下运行。其他关于DLNA的内容可参照现有技术，本申请不再赘述。
在图12中，显示设备中可以包括DLNA协议栈和媒体中心应用，终端设备发起投屏时向DLNA协议栈发送投屏请求。DLNA协议栈接收到投屏请求后，向媒体中心应用发送onCheckBlackList回调信息；媒体中心应用的CheckBlackList接口响应onCheckBlackList回调信息，启动CheckBlackList逻辑，控制显示器显示提示弹窗，检测是否接收到用户输 入的允许指令，如果未检测到用户输入的允许指令，即用户选择“不同意”，则拒绝本次投屏请求，结束流程；如果接收到用户输入的允许指令，即用户选择“同意”或“永久同意”，则进入下一步处理逻辑。
当用户响应投屏请求，允许设备连接以及播放推荐片源时，终端设备向显示设备发送初始片源的URI，DLNA协议栈接收到初始片源的URI之后，向媒体中心应用发送onSetURI回调信息，onSetURI回调信息携带有初始片源的URI；媒体中心应用的SetURI接口响应onSetURI回调信息，启动onSetURI逻辑，解析初始片源的关键字。
然后，DLNA协议栈向媒体中心应用发送onCheckMsg回调信息；媒体中心应用的CheckMsg接口响应onCheckMsg回调信息，启动CheckMsg逻辑，根据关键字生成第一指令，并将第一指令发送至服务器；服务器响应第一指令后获取推荐信息，并将推荐信息发送给媒体中心应用。
DLNA协议栈根据媒体中心应用反馈的推荐信息，判断推荐信息是否为空；如果推荐信息为非空，则向媒体中心应用发送播放指令onPlay，媒体中心应用启动播放逻辑：显示器根据播放指令起播初始片源。初始片源播放过程中，检测是否接收到用户对推荐片源的点击操作；如果接收到对推荐片源的点击操作，退出初始片源并起播推荐片源；如果未接收到对推荐片源的点击操作，则检测初始片源是否播放结束；如果初始片源播放结束，则起播推荐片源，如果初始片源未播放结束，则返回继续检测是否接收到用户对推荐片源的点击操作。
本领域的技术人员可以清楚地了解到本发明实施例中的技术可借助软件加必需的通用硬件平台的方式来实现。具体实现中，本发明还提供一种计算机存储介质，其中，该计算机存储介质可存储有程序，当计算机存储介质位于显示设备中时，该程序执行时可包括控制器250被配置执行的步骤。其中，计算机存储介质可为磁碟、光盘、只读存储记忆体(英文：read-only memory，简称：ROM)或随机存储记忆体(英文：random access memory，简称：RAM)等。
为了方便解释，已经结合具体的实施方式进行了上述说明。但是，上述示例性的讨论不是意图穷尽或者将实施方式限定到上述公开的具体形式。根据上述的教导，可以得到多种修改和变形。上述实施方式的选择和描述是为了更好的解释原理以及实际的应用，从而使得本领域技术人员更好的使用所述实施方式以及适于具体使用考虑的各种不同的变形的实施方式。
