图2为本发明提供的节目切换实现方法的另一个实施例的流程示意图；
图3为本发明提供的节目切换实现装置实施例的模块结构示意图；
图4为本发明提供的节目切换实现装置的又一个实施例的模块结构示意图。
为使本发明的目的、技术方案和优点更加清楚明白，以下结合具体实施例，并参照附图，对本发明进一步详细说明。
需要说明的是，本发明实施例中所有使用“第一”和“第二”的表述均是为了区分两个相同名称非相同的实体或者非相同的参量，可见“第一”“第二”仅为了表述的方便，不应理解为对本发明实施例的限定，后续实施例对此不再一一说明。
本发明的第一个方面，提出了一种在节目切换过程中能够向用户提供一些相关的节目信息从而改善用户枯燥乏味的感受的节目切换实现方法。如图1所示，为本发明提供的节目切换实现方法的一个实施例的流程示意图。
所述节目切换实现方法，包括以下步骤：
步骤101：在接收到节目切换指令后，在后台加载下一节目；即，加载下一节目的过程不显示给用户，仅在后台进行加载；
步骤102：获取所述节目切换指令接收时的最后一帧节目画面，并显示所述
最后一帧节目画面，从而在接收到节目切换指令后，首先将所述最后一帧节目画面定格显示在屏幕上；所述最后一帧节目画面是指，在节目切换指令接收时的时间节点，正在播放的节目的最后一帧画面；
此时，在显示最后一帧节目画面的同时，可以选择在最后一帧节目画面中显示Loading进度圈，从而提示用户当前正在加载下一节目，而不是出现了卡屏的现象；
步骤103：获取下一节目的节目信息，并在所述最后一帧节目画面中显示所述节目信息；
这里，进一步将下一节目的节目信息显示在屏幕中，给予用户一定的下一节目的信息；所述节目信息包括节目名称、节目简介、节目的起止时间等等，该节目信息可以选择显示在屏幕右上角；
步骤104：获取下一节目的第一帧节目画面，并将画面切换显示为所述第一帧节目画面；
这里，先将下一节目的第一帧节目画面加载完成后，将画面切换显示为所述第一帧节目画面，从而给予用户下一节目的画面预览；此时，所述Loading进度圈和节目信息都可以保留，仅所述最后一帧节目画面被替换；
步骤105：在下一节目的内容加载完成时，开始播放所述下一节目；
这里，开始播放所述下一节目时，可以是将播放窗口设为第一优先级，使其被启动播放时直接覆盖前述显示的多个内容，即前述显示的多个内容不被删除，通过启动播放时将被设为第一优先级的播放窗口覆盖显示在前述显示的多个内容之上，从而在视觉效果上仅能看到开始播放所述下一节目的播放窗口；也可以是，播放窗口一直存在，但其优先级低于前述显示的多个内容，因此，在可以开始播放下一节目时，将前述显示的多个内容删除后，播放窗口才再次显示在最上层，从而在视觉效果上再次看到播放窗口，再开始播放所述下一节目。
从上述实施例可以看出，本发明的一个实施例提供的节目切换实现方法，通过在切换节目后加载节目的过程中逐步显示切换前节目的最后一帧节目画面、下一节目的节目信息、下一节目的第一帧节目画面，形成了切台时画面定格，显示loading圈(可选)及下一节目的节目信息，接着显示下一节目的第一帧节目画面，播放开始后将以上画面消失的视觉效果，从而用户在等待下一节目的加载过程中，不会显得无所事事，而可以在节目加载过程中获得一些下一节目的简要信息，提升了用户的换台体验；同时，通过及时有效的为用户提供
这些简要信息，用户还可以根据这些信息大致了解自己是否对其感兴趣，从而可以再次切台，而无需等待节目加载。
为了使下一节目的第一帧节目画面的显示不影响所述最后一帧节目画面的显示，进一步的，在一些可选实施方式中，所述获取下一节目的第一帧节目画面，并将画面切换显示为所述第一帧节目画面的步骤104还具体包括以下步骤：
在所述最后一帧节目画面之上设置所述下一节目的第一帧节目画面显示浮层；
将所述第一帧节目画面显示浮层处理为全透明；可选的，使用Fresco的GenericDraweeHierarchy将第一帧节目画面的默认背景设置为全透明；
在所述第一帧节目画面显示浮层中加载所述第一帧节目画面；
在所述第一帧节目画面加载完成后，逐渐改变所述第一帧节目画面显示浮层的透明度，并最终显示所述第一帧节目画面；可选的，使用AbstractDraweeController设置第一帧节目画面在下载成功后遍渐变显示来达成最终的效果；此外，在逐渐显示第一帧节目画面前，还可以选择先删除所述最后一帧节目画面。
有时候，当网络状况不好时，加载节目的过程会很长，因此，在一些可选实施方式中，所述获取下一节目的第一帧节目画面，并将画面切换显示为所述第一帧节目画面的步骤104之后还可包括以下步骤：
判断在第一预设阈值时间内是否加载完成下一节目；所述第一预设阈值时间可以是默认设置的，也可以是用户自定义设置的，例如1分钟；
若在第一预设阈值时间内没有加载完成下一节目，则获取下一节目的多个关键帧节目画面；这里的关键帧节目画面可以是服务器预先设置好的，只需要终端向服务器发出请求从而获取服务器返回的数据即可，所述关键帧的选取可以是通过等间隔截取节目画面而得到，也可以是根据不同节目内容进行的特别帧的选取；
根据第一预设时间间隔，顺序显示所述多个关键帧节目画面；所述第一预设时间间隔是指，多个关键帧节目画面的显示时间间隔，例如，每隔2秒切换到下一关键帧节目画面，等等；所述第一预设时间间隔可以是默认设置的，也可以是用户自定义设置的。
通过设置第一预设阈值时间，使得在网络状况较差的情况下，可以通过向用户顺序显示多个关键帧节目画面以供用户大致了解下一节目的情况，而不会仅仅是看到下一节目的第一帧节目画面，从而提升了用户体验。
在另一些可选实施方式中，所述获取下一节目的第一帧节目画面，并将画面切换显示为所述第一帧节目画面的步骤104之后还可包括以下步骤：
判断在第二预设阈值时间内是否加载完成下一节目；所述第二预设阈值时间可以是默认设置的，也可以是用户自定义设置的；其可以是与所述第一预设阈值时间相同的，例如1分钟，此时，本实施例与上一实施例为并列技术方案；当然所述第二预设阈值时间也可以与所述第一预设阈值时间不相同，例如3分钟，当达到3分钟时，则进一步采用本实施例的步骤；
若在第二预设阈值时间内没有加载完成下一节目，则获取下一节目所在电视台的节目单；所述节目单中列出了下一节目所在电视台的节目列表，其中包含节目的一些基本信息，例如播出时间、播出内容等等；
根据所述节目单，依次获取在下一节目之后播出的所述电视台的多个节目的第一帧节目画面；
根据第二预设时间间隔，顺序显示所述多个节目的第一帧节目画面；可选的，在每个节目的第一帧节目画面中还可以显示该节目的播出内容和播出时间。
通过设置第二预设阈值时间，使得在网络状况较差的情况下，在一种实施方式中，当第二预设阈值时间与第一预设阈值时间相同时，通过向用户顺序显示多个节目的第一帧节目画面以供用户大致了解下一节目所在电视台接下来的播出情况，而不会仅仅是看到下一节目的第一帧节目画面，从而提升了用户体验；在另一种实施方式中，当第二预设阈值时间与第一预设阈值时间不同时，可以在达到第二预设阈值时间后，向用户顺序显示多个节目的第一帧节目画面以供用户进一步地大致了解下一节目所在电视台接下来的播出情况，从而提升了用户体验。
进一步的，在一些可选实施方式中，所述获取下一节目所在电视台的节目单的步骤包括：
从下一节目的第一帧节目画面中，通过图像处理，分析得到下一节目所在电视台的台标；这里，可选的实现方式可以是，通过从所述第一帧节目画面左上角提取出台标图像，然后通过图像匹配算法找到与该台标图像匹配的台标；
根据所述台标，匹配得到相应的电视台信息；
向服务器发送包含所述电视台信息的节目单获取请求；
接收所述服务器返回的节目单；
这里，还可以是，在得知台标对应的电视台后，通过网络途径查找到该电视台当天的节目单，而无需经过服务器。
本发明还提供了所述节目切换实现方法的另一个实施方式。如图2所示，为本发明提供的节目切换实现方法的另一个实施例的流程示意图。
所述节目切换实现方法，包括以下步骤：
步骤201：在接收到节目切换指令后，在后台加载下一节目；
步骤202：获取所述节目切换指令接收时的最后一帧节目画面，并显示所述最后一帧节目画面；
步骤203：获取下一节目的节目信息，并在所述最后一帧节目画面中显示所述节目信息；
步骤204：在所述最后一帧节目画面之上设置所述下一节目的第一帧节目画面显示浮层；
步骤205：将所述第一帧节目画面显示浮层处理为全透明；
步骤206：在所述第一帧节目画面显示浮层中加载所述第一帧节目画面；
步骤207：在所述第一帧节目画面加载完成后，逐渐改变所述第一帧节目画面显示浮层的透明度，并最终显示所述第一帧节目画面；
步骤208：判断在第一预设阈值时间内是否加载完成下一节目；
步骤209：若在第一预设阈值时间内加载完成下一节目，则进入步骤217；
步骤210：若在第一预设阈值时间内没有加载完成下一节目，则获取下一节目的多个关键帧节目画面；
步骤211：根据第一预设时间间隔，顺序显示所述多个关键帧节目画面；
步骤212：判断在第二预设阈值时间内是否加载完成下一节目；
步骤213：若在第二预设阈值时间内加载完成下一节目，则进入步骤217；
步骤214：若在第二预设阈值时间内没有加载完成下一节目，则获取下一节目所在电视台的节目单；
步骤215：根据所述节目单，依次获取在下一节目之后播出的所述电视台的多个节目的第一帧节目画面；
步骤216：根据第二预设时间间隔，顺序显示所述多个节目的第一帧节目画面；
步骤217：在下一节目的内容加载完成时，开始播放所述下一节目。
从上述实施例可以看出，本发明的另一个实施例提供的节目切换实现方法，通过在切换节目后加载节目的过程中逐步显示切换前节目的最后一帧节目画面、下一节目的节目信息、下一节目的第一帧节目画面，形成了切台时画面定格，显示loading圈(可选)及下一节目的节目信息，接着显示下一节目的第一
帧节目画面，播放开始后将以上画面消失的视觉效果，从而用户在等待下一节目的加载过程中，不会显得无所事事，而可以在节目加载过程中获得一些下一节目的简要信息，提升了用户的换台体验；同时，通过及时有效的为用户提供这些简要信息，用户还可以根据这些信息大致了解自己是否对其感兴趣，从而可以再次切台，而无需等待节目加载。

目信息、下一节目的第一帧节目画面，形成了切台时画面定格，显示下一节目的节目信息，接着显示下一节目的第一帧节目画面，播放开始后将以上画面消失的视觉效果，从而用户在等待下一节目的加载过程中，不会显得无所事事，而可以在节目加载过程中获得一些下一节目的简要信息，提升了用户的换台体验；同时，通过及时有效的为用户提供这些简要信息，用户还可以根据这些信息大致了解自己是否对其感兴趣，从而可以再次切台，而无需等待节目加载。
参照图4所示，为本发明提供的一种在节目切换过程中能够向用户提供一些相关的节目信息从而改善用户枯燥乏味的感受的节目切换实现装置4的一个实施例的模块结构示意图。所述节目切换实现装置4包括：处理器41、存储器42、总线系统43。其中，处理器41和存储器42通过总线系统43相连，该存储器42用于存储指令，该处理器41用于执行该存储器42存储的指令，用于：
在接收到节目切换指令后，在后台加载下一节目；
获取所述节目切换指令接收时的最后一帧节目画面，并显示所述最后一帧节目画面；
获取下一节目的节目信息，并在所述最后一帧节目画面中显示所述节目信息；
获取下一节目的第一帧节目画面，并将画面切换显示为所述第一帧节目画面；
在下一节目的内容加载完成时，开始播放所述下一节目。
节目切换实现装置4的存储器42可以是非易失性计算机可读存储介质，以用于存储计算机可执行指令，该指令当由一个或多个处理器执行时，可以使得处理器执行以上方法实施例的步骤，比如，如图1描述的步骤101至105。或者如图2描述的步骤201至217，或者，可以使得处理器执行以上装置实施例各模块的功能，比如，如图3所示模块301至311的功能。计算机可执行指令也可以在任何非易失性计算机可读存储介质内存储和/或传输，以便由指令执行系统、装置或设备使用，或者结合指令执行系统、装置或设备使用，其中该指令执行系统、装置或设备诸如基于计算机的系统、包含处理器的系统或可以从指令执行系统、装置或设备获取指令并执行该指令的其他系统。出于本文档的目的，“非易失性计算机可读存储介质”可以是有形地包含或存储计算机可执行指令的任何介质，该计算机可执行指令可以用于由指令执行系统、设备或系统使用或者结合指令执行系统、装置或设备使用。非易失性计算机可读存储介质可以包括但不限于磁的、光的和/或半导体存储装置。这些存储装置的示例包括磁盘、基
于CD、DVD或蓝光技术的光盘以及持久性固态存储器(诸如，闪存、固态驱动器等)。
应当理解，在本申请实施例中，该处理器41可以是中央处理单元(Central Processing Unit，简称为“CPU”)。该处理器41还可以是其他通用处理器、数字信号处理器(DSP)、专用集成电路(ASIC)、现成可编程门阵列(FPGA)或者其他可编程逻辑器件、分立门或者晶体管逻辑器件、分立硬件组件等。通用处理器可以是微处理器或者该处理器也可以是任何常规的处理器等。
该总线系统43除包括数据总线之外，还可以包括电源总线、控制总线和状态信号总线等。但是为了清楚说明起见，在图中将各种总线都标为总线系统43。
在本发明实施例中，节目切换实现装置不限于图4的部件和配置，还可以包括以多种配置形式的其他或附加部件。
在实现过程中，上述方法的各步骤或装置的各模块可以通过处理器41中的硬件的集成逻辑电路或者软件形式的指令完成。结合本申请实施例所公开的方法的步骤或装置的各单元可以直接体现为硬件处理器执行完成。或者用处理器中的硬件及软件模块组合执行完成。软件模块可以位于随机存储器，闪存、只读存储器，可编程只读存储器或者电可擦写可编程存储器、寄存器等本领域成熟的存储介质中。该存储介质位于存储器42，处理器41读取存储器42中的信息，结合其硬件完成上述方法的步骤。为避免重复，这里不再详细描述。
从上述实施例可以看出，本发明实施例提供的节目切换实现装置，通过在切换节目后加载节目的过程中逐步显示切换前节目的最后一帧节目画面、下一节目的节目信息、下一节目的第一帧节目画面，形成了切台时画面定格，显示loading圈(可选)及下一节目的节目信息，接着显示下一节目的第一帧节目画面，播放开始后将以上画面消失的视觉效果，从而用户在等待下一节目的加载过程中，不会显得无所事事，而可以在节目加载过程中获得一些下一节目的简要信息，提升了用户的换台体验；同时，通过及时有效的为用户提供这些简要信息，用户还可以根据这些信息大致了解自己是否对其感兴趣，从而可以再次切台，而无需等待节目加载。
所属领域的普通技术人员应当理解：以上任何实施例的讨论仅为示例性的，并非旨在暗示本公开的范围(包括权利要求)被限于这些例子；在本发明的思路下，以上实施例或者不同实施例中的技术特征之间也可以进行组合，并存在如
上所述的本发明的不同方面的许多其它变化，为了简明它们没有在细节中提供。因此，凡在本发明的精神和原则之内，所做的任何省略、修改、等同替换、改进等，均应包含在本发明的保护范围之内。
