Description

信号源的处理方法及装置
本申请要求在2015年07月13日提交中国专利局、申请号为201510410079.X、发明名称为“信号源的处理方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明实施例涉及视频技术领域，尤其涉及一种信号源的处理方法及装置。
背景技术
电视机是一台显示设备，其需要有信号源提供图像信号才能够显示各种各样的画面。电视机和信号源之间往往通过接口来实现对接并传输信号，考虑到不同的信号源存在不同的接口类型，电视机通常会配备多组不同的接口类型供用户选择使用。
例如，常见的接口类型具体包括AV复合视频接口、S-端子接口、色差接口、VGA(Video Graphics Array，视频图形阵列)接口、DVI(Digital Visual Interface，数字视频接口)、HDMI(High Definition Multimedia Interface，高清晰度多媒体接口)、有线电视接口等等。用户可以通过配备的接口类型在不同的信号源间进行切换。
然而，信号源接口的名称通常具有专业性，这使得一般用户对于切换信号源的操作并不熟悉，用户很难理解和区分各信号源接口的名称，不知道自己是否将当前所需的设备插入了对应的信号源接口。并且，用户也无法确定是否在电视机上选择了正确的信号源，只能对信号源逐个插拔和选择来进行信号源的切换，这严重影响了信号源的切换效率。
发明内容
本发明实施例提供一种信号源的处理方法及装置，用以提高信号源的切换效率。
本发明实施例提供一种信号源的处理方法，包括：
监测显示设备中各个信号源接口的接口状态；其中，所述接口状态包括：插入状态或者拔出状态；
在所述显示设备上显示所述信号源接口的接口状态。
本发明实施例提供一种信号源的处理装置，包括：
监测模块，配置为监测显示设备中各个信号源接口的接口状态；其中，所述接口状态包括：插入状态或者拔出状态；及
显示模块，配置为在所述显示设备上显示所述信号源接口的接口状态。
本发明实施例还提供了一种在其上记录有用于执行上述方法的程序的计算机可读记录介质。
本发明实施例提供的信号源的处理方法及装置，通过监测显示设备中各个信号源接口的接口状态，并在显示设备上显示各信号源接口的接口状态，使得用户可以直观地看到各信号源接口处于插入状态还是拔出状态，其中，处于插入状态的信号源接口也即为可用的信号源接口，用户可以直接从当前可用的信号源接口中选择目标信号源，这相对于传统方案，避免了逐个插拔并切换进行尝试的过程，简化了切换信号源的操作流程，降低了切换信号源的难度，从而可以提高切换信号源的效率。

在本发明实施例中，显示设备具体可以为智能电视等各种具有显示功能的设备，本发明实施例主要以智能电视为例进行说明，其它显示设备相互参照即可。
智能电视，是指具有全开放式平台，搭载了操作系统，可以由用户自行安装和卸载软件、游戏等第三方服务商提供的程序的电视。智能电视和传统电视一样，可以配备多个信号源接口，以连接不同的设备，例如，HDMI(High Definition Multimedia Interface，高清晰度多媒体接口)是一种全数字化图像和声音传送接口，可用于连接机顶盒、DVD播放机、个人电脑、电视游乐器、综合扩大机、数字音响等设备；而VGA(Video Graphics Array，视频图形矩阵)接口，具有分辨率高、显示速率快、颜色丰富等优点，在彩色显示器领域得到了广泛的应用，可用于连接投影仪、背投等设备。
用户在使用智能电视时可以在不同的设备间切换，即可以在不同的信号源间切换。然而，用户在切换信号源的过程中，通常只能看到各信号源的名称，并不知道各信号源处于插入状态还是拔出状态，即不知道是否将当前所需的设备插入了对应的信号源接口。
为了降低切换信号源的难度、提高切换信号源的效率，本发明实施例可以监测各信号源接口的接口状态，如插入状态或者拔出状态，并在显示设备(如智能电视)的界面中显示各信号源接口的接口状态，例如，某台智能电视具有3个信号源接口：接口1、接口2和接口3，通过监测该智能电视各信号源接口的接口状态可以得知，其中，接口1和接口2处于插入状态，接口3处于拔出状态，那么，可以在显示界面中显示接口1和接口2的接口状态为插入状态，接口3的接口状态为拔出状态。
在实际应用中，具体的显示方式可以有多种，例如，可以在列表1中列出插入状态的信号源接口有哪些，在列表2中列出拔出状态的信号源接口有哪些；又如，还可以分别标注各个信号源接口的接口状态等等，本发明实施例对于接口状态的具体显示方式不加以限制。
综上，本发明实施例在显示设备的界面中显示各信号源接口的接口状态，能够使得用户直观地看到各信号源接口所处的接口状态，从而用户可以得知是否将当前所需的设备插入了对应的信号源接口，其中，处于插入状态的信 号源接口即为可用的信号源接口，用户可以依据当前可用的信号源接口进行信号源的切换，相对于传统方案，避免了逐个插拔并切换来进行尝试的过程，简化了复杂的切换信号源的操作流程，提高了切换效率。
需要说明的是，上述HDMI、VGA接口只是作为所述信号源接口的一种应用示例，在实际应用中，智能电视中还可以设置有多种其它的信号源接口，本发明实施例可以对智能电视的多个信号源接口的接口状态进行监测，本发明实施例对于信号源接口的种类和数量不加以限制。
在本发明的一种优选实施例中，所述监测显示设备中各个信号源接口的接口状态的步骤，具体可以包括：
在初始化过程中，采用第一线程轮询所述各个信号源接口的状态值信息；
在所述第一线程在所述显示设备上显示所述信号源接口的接口状态的过程中，采用第二线程定时轮询所述各个信号源接口的状态值信息，以使所述第一线程依据定时轮询结果进行所述信号源接口的接口状态的显示。
在具体应用中，在本发明的信号源的处理系统初始化时，可以通过设置的第一线程来轮询各信号源接口的状态值信息，所述状态值信息与所述接口状态可以具有映射关系，例如，轮询得到某个信号源接口的状态值信息为1，则对应的该信号源接口的接口状态为插入状态；若状态值信息为0，则对应的该信号源接口的接口状态为拔出状态。由此，可以得到当前显示设备的各信号源接口的接口状态。当然，上述通过轮询信号源接口的状态值信息确定接口状态的方法仅作为本发明的一种应用示例，在实际应用中，本领域技术人员可以根据实际情况灵活选取确定接口状态的方法，本发明对此不加以限制。
在本发明实施例中，在用户初次打开显示设备时，可以通过第一线程轮询信号源接口的状态值信息，以及显示出各信号源接口的接口状态，提示用户哪些信号源可以使用，避免了用户对信号源接口逐个插拔来确定信号源接口的接口状态。
另外，在用户在观看显示设备播放内容的过程中，还可以通过第二线程定时轮询各信号源接口的状态值信息，定时轮询对应的时间间隔可以根据系统的性能进行调整，并在监测到人为插拔信号源设备时，可以及时地将对应信号源接口的接口状态的变化通知给第一线程，例如，对于某个信号源接口，当前在显示设备中显示的接口状态为插入状态，此时，用户将插入该信号源接口的设备拔出，由于监测到该信号源接口的状态值发生变化，因此，可以将该信号源接口的接口状态的变化通知给第一线程，以使所述第一线程依据定时轮询结果进行所述信号源接口的接口状态的显示，从而起到向用户显示最新的接口状态的效果。
在具体实现中，上述第一线程可以为系统的主线程，其可用于实现系统初始化、初始化后的UI显示等功能，其中，其可以在系统初始化过程中轮询各信号源接口的状态值信息；第二线程可以为系统的子线程，其可用于在初始化后定时轮询所述各个信号源接口的状态值信息。
在本发明的一种优选实施例中，所述监测显示设备中各个信号源接口的接口状态的步骤，具体可以包括：
步骤A1、轮询所述各个信号源接口的状态值信息；其中，所述状态值信息与所述接口状态具有映射关系；
其中，上述轮询具体可以包括：系统初始化过程中轮询和系统初始化后轮询等，具体参照上述第一线程和第二线程的介绍，在此不作赘述。
步骤A2、将所述状态值信息存储在数据结构中；
在轮询得到各信号源接口的状态值信息后，可以将上述状态值信息存储在数据结构中，从而，本发明实施例的信号源的处理系统可以读取该数据结构中存储的状态值信息，以及在显示设备中显示所读取的状态值信息对应的接口状态。在本发明实施例中，优选的是，可以将状态值信息转换为布尔类型(boolean)的状态值信息，并对布尔类型的状态值信息进行存储，例如，将上述示例中的状态值信息1存储为True，0存储为False，这样，在读取状 态值信息时，如果是Tree，则认为对应的信号源接口为插入状态，如果是False，则认为对应的信号源接口为拔出状态，可以直接识别出信号源接口的接口状态。
在本发明的一种优选实施例中，所述数据结构可以为数组，所述数组的长度可以与被监测的信号源接口的数目相应。对于数据结构，本发明实施例优选地采用数组对所述状态值信息进行存储，并且设置数组的长度为被监测的信号源接口的数目，大多的显示设备例如智能电视，其信号源接口的数量通常是固定的，因此，数组中存储的状态值信息与信号源接口可以具有一一对应的关系。例如，当前显示设备具有10个接口，则可以设置数组array的长度为10，当需要读取第5个信号源接口的状态值时，可以直接读取array[4]的值即可，可以不用在数据库中进行查询匹配，也即，采用数组作为上述数据结构，具有使用方便、节省资源的优点。
当然，本领域技术人员应该知悉，在实际应用中，可以选用其他的数据结构，比如List(列表)或Map(映射)等来存储上述状态值信息，本发明对于数据结构的具体类型不加以限制。
步骤A3、在被监测的信号源接口的状态值发生变化时，对所述数据结构中对应信号源接口的状态值信息进行更新。
在具体实现中，可以由第一线程建立上述数据结构，且由第二线程对上述数据结构中内容进行维护。例如，在第二线程监测到有信号源接口的状态值信息发生变化时，可以对所述数据结构中对应信号源接口的状态值信息进行更新。其中，在数组中的状态值信息需要进行更新时，可以更新对应的数组标记位，可以不用更新数据内容，例如，对于指定位置的数组值，其对应信号源接口的接口状态发生变化，则对该指定位置的数组值取反即可，如：array[position]＝！array[position]；这样既可以节省系统资源，又可以加快处理速度。
在对所述数据结构中对应信号源接口的状态值信息进行更新之后，即可 依据更新后的状态值信息对显示的接口状态进行更新，以及时提示用户。
步骤102、在所述显示设备上显示所述信号源接口的接口状态。
在具体实现中，可以将监测得到的信号源接口的接口状态在显示设备上进行显示，以使得用户可以直观地看到各信号源接口处于插入状态还是拔出状态。优选地，为了向用户更加直观地展示出可用的信号源接口，可以在所述显示设备上对所述信号源接口的插入状态或者拔出状态进行区别显示，也即，可以采用不同的显示方式以突出显示插入状态或者拔出状态。
在本发明的一种应用示例中，可以通过信号源列表显示信号源接口的接口状态。参照图2，示出了本发明的一种在显示设备上显示所述信号源接口的接口状态的界面示意图，其中右侧的信号源列表中列出了当前显示设备的所有信号源接口对应的名称，以及各信号源接口的接口状态。为了突出显示信号源接口的插入状态，在具体应用中，可以对处于插入状态的信号源接口，在信号源列表中以高亮的方式显示，如电视、电脑、CVBS(Composite Video Broadcast Signal，复合视频广播信号)、HDMI1这几个信号源接口处于插入状态，则以高亮的方式显示；而对处于拔出状态的信号源接口，如HDMI2和HDMI3这两个信号源接口，则以灰色的方式显示。用户可以更加直观地看出当前显示设备的多个信号源接口中哪些信号源接口处于插入状态，即处于可用状态，避免了用户逐个插拔和选择来进行信号源的切换过程，简化了用户选择信号源的操作流程。
需要说明的是，上述以高亮的方式显示处于插入状态的信号源接口，以灰色的方式显示处于拔出状态的信号源接口，只是作为对所述信号源接口的插入状态或者拔出状态进行区别显示的方式的一种应用示例，而不理解为本发明实施例对于上述区别显示的方式的应用限制，实际上，本领域技术人员还可以根据实际情况采用其它区别显示的方式，如以下划线、弹窗等方式显示处于插入状态的信号源接口等等。
综上，本发明实施例监测显示设备中各个信号源接口的接口状态，并在 显示设备上显示各信号源接口的接口状态，使得用户可以直观地看到各信号源接口处于插入状态还是拔出状态，其中，处于插入状态的信号源接口也即为可用的信号源接口，用户可以直接从当前可用的信号源接口中选择目标信号源，这相对于传统方案中避免了逐个插拔并切换进行尝试的过程，简化了切换信号源的操作流程，降低了切换信号源的难度，从而可以提高切换信号源的效率。
实施例二
参照图3，示出了本发明的一种信号源的处理方法实施例二的步骤流程图，具体可以包括：
步骤301、监测显示设备中各个信号源接口的接口状态；其中，所述接口状态具体可以包括：插入状态或者拔出状态；
步骤302、在所述显示设备上显示所述信号源接口的接口状态；
步骤303、在被监测的信号源接口从拔出状态变化为插入状态时，输出提示信息；其中，所述提示信息中可以包括对应信号源接口的名称信息、以及询问信息；所述询问信息用于询问用户是否打开所述信号源接口对应的信号源；
步骤304、在接收到用户针对所述询问信息的确定打开的触发指令时，将所述显示设备切换到对应的信号源。
相对于实施例一，本实施例还可以在被监测的信号源接口从拔出状态变化为插入状态时，输出提示信息；其中，所述提示信息中既可以包括对应信号源接口的名称信息，以通知用户插入的当前信号源接口；所述提示信息中还可以包括询问信息，使得用户通过该询问信息更快捷地将显示设备切换到当前信号源接口对应的信号源。
参照图4，示出了本发明的一种提示信息的界面示意图，其中，在监测到HDMI1信号源接口有设备插入时，可以弹出提示信息，该提示信息中可以 包含文本信息：“HDMI1有设备接入，立即打开该信号源？”，该提示信息中还可以包括两个控件：“立即打开”和“取消”控件，在用户点击“立即打开”控件时，可以认为用户针对所述询问信息发出了触发确定打开的指令，则将显示设备切换到对应的HDMI1信号源，并在当前显示界面中显示该HDMI1信号源的画面。
综上，本发明实施例实现了用户在插入设备时，即可立即打开该设备对应的信号源，避免了用户再在多个信号源接口中进行切换的过程，降低了切换信号源的难度，从而可以提高切换信号源的效率。
实施例三
参照图5，示出了本发明的一种信号源的处理方法实施例三的步骤流程图，具体可以包括：
步骤501、监测显示设备中各个信号源接口的接口状态；其中，所述接口状态具体可以包括：插入状态或者拔出状态；
步骤502、在所述显示设备上显示所述信号源接口的接口状态；
步骤503、在检测到针对所显示信号源接口的焦点由当前的信号源接口移动至另一信号源接口时，显示当前所述焦点所在的该另一信号源接口所对应的信号源的预览画面。
相对于实施例一，本实施例还可以在检测到针对所显示信号源接口的焦点由当前的信号源接口移动至另一信号源接口时，显示当前所述焦点所在的该另一信号源接口所对应的信号源的预览画面；相对于信号源接口的名称，上述预览画面可以更直观地显示信号源的特征信息，以使用户更准确地确定所需的信号源。
如图2所示的信号源列表的界面示意图，在信号源列表的左侧可以设有显示区域，该区域可以用来显示右侧信号源列表中各信号源对应的预览画面。例如，当焦点在所述信号源列表中进行移动时，可以在显示区域显示当前焦 点所在信号源接口对应信号源的预览画面。如图2所示，当前焦点在信号源列表中的“电脑”上，则左侧的显示区域中可以显示电脑的预览画面。
在本发明的一种优选实施例中，所述方法还可以包括：在当前焦点的停留时间满足第一阈值条件时，将所述显示设备切换到对应的信号源；在当前焦点的停留时间满足第二阈值条件时，全屏显示对应的信号源的画面。
例如，在检测到针对所显示信号源接口的焦点由当前的信号源接口移动至另一信号源接口时，可以在显示设备中显示当前所述焦点所在的该另一信号源接口所对应的信号源的预览画面，此时，并未执行信号源的切换操作，只是为用户显示该信号源的预览画面，以方便用户判断是否需要切换到该信号源。如果焦点在该信号源接口上的停留时间满足第一阈值条件，如大于2s，则认为用户想要继续观看该信号源的画面，因此，自动将显示设备切换到该信号源，如果焦点在该信号源接口上的停留时间满足第二阈值条件，如大于15s，则全屏显示该信号源的画面。本优选实施例通过设置第一阈值条件和第二阈值条件，自动为执行信号源的切换操作以及画面的全屏显示操作，进一步简化了用户切换信号源的操作流程，并且使得操作过程更加方便和人性化。
综上，本实施例可以实现对信号源画面的快捷预览，以帮助用户在切换信号源时，准确地确定所需的信号源，用户可以不用理解复杂的信号源接口名称，因此能够降低切换信号源的难度，以及提高切换信号源的效率。
实施例四
参照图6，示出了本发明的一种信号源的处理系统实施例的流程框图，具体可以包括：
步骤601、在初始化过程中，采用第一线程轮询各信号源接口的状态值信息；
在本发明实施例中，可以在信号源的处理系统的UI(User Interface，用户界面)中，为用户显示各信号源接口的接口状态。具体地，UI界面的显示 可以依据一个定长的布尔类型的数组，通过读取数组中的数据值确定各信号源接口的接口状态，以及确定该信号源接口在UI中是否以高亮显示。
在信号源的处理系统初始化的过程中，可以创建第一线程，并通过该第一线程轮询各信号源接口的状态值信息，识别出各信号源接口的接口状态，并依据所述状态值信息初始化数组。
步骤602、依据第一线程轮询得到的状态值信息，显示系统的UI；
在具体实现中，第一线程可以根据步骤601得到的状态值信息，显示系统的初始UI，例如，若数组中的状态值信息为真(Tree)，表示该状态值信息对应的信号源接口处于插入状态，则可以将该信号源接口以高亮显示，否则以灰色显示，表明该信号源接口处于拔出状态。
步骤603、当所述第一线程在所述显示设备上显示所述信号源接口的接口状态的过程中，采用第二线程定时轮询各信号源接口的状态值信息；
在具体实现中，可以建立第二线程，该第二线程可以常驻内存区，并可以定时轮询各个信号源接口的状态值信息，其中，定时轮询对应的时间间隔可以根据系统的性能进行调整。
通过第一线程的轮询，可以在系统初始UI中展示出所有信号源接口的接口状态，通过第二线程的轮询，可以在信号源运行过程中随时监测信号源接口的动态变化，依据信号源接口的动态变化更新存储的状态值信息，以及依据更新后的状态值信息更新UI中的接口状态。在动态变化的过程中，对存储的状态值信息可以只更新变化的部分，从而节省系统的开销。
步骤604、依据第二线程轮询得到的状态值信息，更新数据结构中存储的状态值信息；
根据步骤603中第二线程轮询得到的状态值信息做出判断，如果有信号源接口的状态值信息发生变化，则可以更新数组中对应的状态值信息。
步骤605、依据更新后的状态值信息，更新系统的UI。
在具体实现中，第一线程可以依据步骤604中更新后的状态值信息，更 新UI中显示的各信号源接口的接口状态，由此可以实时显示出各信号源接口的动态变化。
