目前显示设备默认的视频播放模式为对待播放的视频进行画质处理，画质处理可以包括：运动平滑、降噪、锐化、颜色调节、饱和度调节、纵横比调节等。经过画质处理的视频，在画质的流程度和画面的色彩等方面均为用户提供较好的体验感，因此，经过画质处理的视频受到大多数用户的青睐。但是，目前几乎所有的视频都是采用24fps的帧率来拍摄的，在显示设备上面播出后，通常会被转换为60fps，所以画面就失去了本来应该有的效果。一些用户希望可以利用显示设备观看到视频的原始画面。制片人模式(Filmmaker mode)是一项由好莱坞导演支持的计划，将帮助更多的用户观看到原始视频的画面。如何保证显示设备可以满足更多用户的需求，成为亟待解决的技术问题。
为了解决上述技术问题，本申请实施例示出一种显示设备，显示设备可以包括显示器和控制器；显示器与控制器的交互过程可以参阅图4，图4为根据一可行性实施例示出的显示器与控制器的交互流程图；
控制器，被配置为执行步骤S101解码视频数据；
本申请实施例示出的技术方中控制器可以用来接收视频数据，其中视频数据一种信号源可以是机顶盒通过HDMI接口传输的有线视频数据；视频数据一种信号源可以是通过USB接口传输的预先下载的视频数据；视频数据一种信号源可以是通过网络接口传输的网络视频数据。在实际应用的过程中视频数据的信号源可以是其它的形式，在此申请人不做过多的限定。
控制器可以对接收到的视频数据进行解码，其中解码的实现方式可以采用本领域惯用的解码方式在此申请人不做过多的限定。
控制器可以对解码后的视频数据中的Filmmaker Mode(制片人)数据识别进行识别。在实际应用的过程中控制器对解码后的Filmmaker Mode(制片人)信号识别进行识别的实现方式有多种，例如，控制器可以判断解码后的视频数据中是否包含制片人标识，来确定解码后的视频数据中是否包含Filmmaker Mode数据。
具体的，控制器可以读取解码后的视频数据中的AVI(Auxiliary Video Information，辅助音频信息)和VSIF(Video Specific InfoFrame视频特定信息帧)信息。控制器首先检查VSIF是否包含UHDA(Ultra High Definition Alliance，超高画质联盟)定义信息；如果VSIF信息包含了有效的UHDA定义信息，则解码后的视频数据包含制片人标识，此时就忽略AVI信息。如果VSIF信息不符合UHDA定义(VSIF不包含有效的UHDA定义信息)，控制器检查AVI信息中的Data Byte3的Bit7(ITC)。如果ITC＝0，则CN1/CN0无效(解码后的视频数据不包含制片人标识)。当ITC＝1时，识别到CN1/CN0后，如果检测到Cimema内容，则解码后的视频数据包含制片人标识。
如果解码后的视频数据包含制片人标识，控制器执行步骤S1021控制显示器以制片人模式展示视频帧画面，视频帧画面由解码后的视频数据渲染而成；
在显示设备中使用制片人模式将禁用后续的视频处理功能，视频处理功能可以包括：运动平滑、降噪和锐化等处理功能；制片人模式将会遵循视频拍摄过程中的高帧率，宽高 比，颜色和对比度，以保证用户光看到最原始的视频。
如果解码后的视频数据不包含制片人标识，控制器执行步骤S1022控制显示器以预置模式展示视频帧画面，预置模式不同于制片人模式。
本申请实施例示出方案中，预置模式为不同于制片人模式的模式，本实施例中并不对预置模式作以限定，凡是需要对解码后的视频数据进行画质处理或音频处理的模式均可作为预置模式，例如在一些可行性实施例中预置模式可以是运动模式，再例如在一些可行性实施例中预置模式可以是电影模式。
在一可行性实施例中，显示设备可以通过网络接口接收服务器下发的视频信号，显示设备与服务器的交互流程图可以参阅图5；
响应于启动应用的视频播放功能，控制器被配置为执行步骤S11发送视频请求指令至服务器；
本申请中视频请求指令至少包括待播放视频的视频ID，以使得服务器可以调取视频ID对应的视频信号。
服务器被配置为执行步骤S12发送视频数据至控制器。
其中视频数据通过服务器与控制器之间的网络通道进行传输，具体的传输方式可以采用本领域惯用的视频传输方式，在此申请人不做过多的限定。
为了提升用户的体验感，本申请实施例示出的显示设备配置有制片人开关控件，用户可以根据需求触控制片人开关控件，以实现制片人模式的开启或关闭。
具体的实现过程可以是：在一可行性实施例中制片人模式默认为关闭状态，如果解码后的视频数据包含制片人标识，控制器执行步骤S1021A控制显示器展示第一提示信息，第一提示信息用于提示用户制片人模式开启方式；
在一些可行性实施例中，第一提示信息可以以浮层窗口的形式展示，浮层窗户可以设置有制片人开关控件，具体的可以参阅图6的界面11，图6为根据一可行性实施例示出的显示器展示第一提示信息时，显示器的展示界面。从界面11中可以看出第一提示信息“监测到制片人模式，切换至制片人模式可以以制片人的视角去观赏电影，是否切换至制片人模式”以浮层窗口1的形式展示。浮层窗户可以设置有制片人开关控件(11和12)。用户可以通过触控制片人开关控件11，控制显示设备切换至制片人模式，用户可以通过触控制片人开关控件12，控制显示设备切换至预置模式。
在一些可行性实施例中，第一提示信息可以展示在浮层窗口内，第一提示信息用于提示用户制片人模式开启方式，具体的可以参阅图6的界面12，从界面12中可以看出第一提示信息“监测到制片人模式，切换至制片人模式可以以制片人的视角去观赏电影您可以到“图像设置”的菜单中制片人开关控件控制制片人模式的开启或关闭”以浮层窗口的形式展示。用户可以根据第一提示信息，在找到“图像设置”的菜单，然后，在“图像设置”的菜单中找到制片人开关控件，通过触控制片人开关控件控制制片人模式开启式或关闭。响应于用户触发控件13，显示器撤销第一提示信息。
在一可行性实施例中，控制器以控制显示展示第一提示信息的时间为起点，统计第一提示信息的展示时间，如果展示时间等于预置时间，控制显示器撤销第一提示信息。本实施例中并不对预置时间作以限定，在一些可行性实施例中预置时间可以根据需求设定，例如预置时间可以为3s。
图7为根据一可行性实施例示出的显示器展示图像设置菜单时，显示器的展示界面。 可以看出图像设置菜单包括预置开关控件21和制片人开关控件22。用户可以通过触控制片人开关控件来实现控制显示设备开启式或关闭制片人模式。
本申请实施例示出的技术方案，制片人模式的优先级大于预置模式的优先级即当制片人模式和预置模式均处于开启状态时，响应于控制器接收到的视频数据包括制片人标识，控制器控制显示器以制片人模式展示视频帧画面。
举例说明：在图7界面21示出的实施例中，制片人模式和预置模式均处于开启状态，响应于控制器接收到的视频数据包括制片人标识，控制器控制显示器以制片人模式展示视频帧画面。
举例说明：在图7界面22示出的实施例中，制片人开关控件处于关闭状态，预置模式处于开启状态，响应于控制器接收到的视频数据包括制片人标识，控制器控制显示器以预置模式展示视频帧画面。
在一可行性实施例中，控制器还被配置为：响应于显示设备由制片人模式切换至默认模式，关闭制片人模式；响应于显示设备由默认模式切换至制片人模式，默认模式处于开启状态。
举例说明：当前显示设备处于制片人模式，用户通过预置模式控开启预置模式(显示设备由制片模式切换至预置模式)控制器关闭制片人模式，此时显示器展示的图像菜单可以参阅图7的界面22。
举例说明：当前显示设备处于预置模式，用户通过制片人模式控开启制片人模式(显示设备由预置模式切换至制片人模式)控制器不关闭预置模式，此时显示器展示的图像菜单可以参阅图7的界面23。
响应于用户启动制片人模式，控制器执行步骤S1021B控制显示器以制片人模式展示视频帧画面；
如果用户未启动制片人模式，控制器执行步骤S1021C控制显示器以预置模式展示视频帧画面，预置模式不同于制片人模式。
在一些实施例中，为了满足不同的用户需求一些应用会配置有黑名单，黑名单用于记录该应用禁用的一些功能。举例说明：一些视频数据中包含OSD(On Screen Display，在显示器的荧幕中产生一些特殊的字形或图形，让使用者得到一些讯息)层，如果显示设备对该视频在数据进行了运动补偿，那么视频中的OSD层将会被“撕裂”影响用户的体验感，因此，该应用可以将运动补偿功能加入黑名单。在实际应用的过程中，一些应用希望用户看到的视频是经过画质处理的视频，因此这些应用可以将制片人模式加入黑名单。
本实施例中服务器下发的视频数据包括应用的黑名单和白名单，其中，显示设备与服务器的交互过程可以参阅图8。
如果黑名单中包括制片人模式，控制器执行步骤S1022控制显示器以预置模式展示视频帧画面。
如果所述白名单中包括制片人模式且解码后的所述视频数据包含制片人标识，控制器执行步骤S103读取制片人开关控件的标识位；
本申请实施例中，控制器的存储器预先存储制片人开关控件的标识位；当制片人开关控件处于开启状态时，制片人开关控件的标识位为第一标识位；当制片人开关控件处于关闭状态时，制片人开关控件的标识位为第二标识位。
每次响应于用户通过制片人开关控件控制制片人模式开启，控制器将第一标识位为写 入存储器；每次响应于用户通过制片人开关控件控制制片人模式关闭，控制器将第二标识位为写入存储器。为了减少存储器的资源占用空间，本实施例示出的技术方案，每次接收到制片人开关控件的标识位，控制器写入新的标识位后，删除原来存储的标识位，以保证存储内最多存储两个制片人模式标识位。
举例说明：制片人开关控件处于关闭状态，存储器内记录的制片人模式标识位为第二标识位。用户通过制片人开关控件控制显示设备关闭制片人模式。响应于用户对制片人开关控件的触控，控制器将第一标识位写入存储器；响应于完成第一标识位的写入，控制器删除之前的存储的第二标识位。
如果制片人开关控件的标识位为第一标识位，控制器执行步骤S1041控制显示器以制片人模式展示视频帧画面，视频帧画面由解码后的视频数据渲染而成；第一标识位为制片人开关控件处于开启状态，制片人开关控件的标识位；
如果制片人开关控件的标识位为第二标识位，控制器执行步骤S1042控制显示器以预置模式展示视频帧画面，第二标识位为制片人开关控件处于关闭状态，制片人开关控件的标识位。
由于制片人模式为显示设备新添的功能，如果制片人功能始终处于关闭状态，用户无法获知显示设备增添了制片人模式功能，用户体验感较差。
为了提升用户的体验感，在一些可行性实时中显示设备出厂时制片人开关控件处于开启状态。
在一些可行性实施例中可以在用户使用显示设备时，弹出一些用于提示用户该显示设备添加了制片人模式的提示信息。显示设备与服务器的交互过程可以参阅图9。
举例说明，在一些可行性实施例中可以不限制显示设备出厂时，制片人开关控件处于开启状态或关闭状态。首次读取到解码后的视频数据包含制片人标识，控制执行步骤S1021C控制显示器展示第二提示信息，第二提示信息用于提示用户显示设备配置有制片人模式以及制片人模式的使用方法。
在一些可行性实施例中，第二提示信息可以展示在浮层窗口内，浮层窗户可以设置有制片人模式的开关控件，具体的可以参阅图10的界面31。图10为根据一可行性实施例示出的显示器展示第二提示信息时，显示器的展示界面。从界面31中可以看出第二提示信息“显示设备新添制片人模式，切换至制片人模式可以以制片人的视角去观赏电影，是否切换至制片人模式”以浮层窗口1的形式展示。浮层窗户可以设置有制片人开关控件(11和12)。用户可以通过触控控件11，控制显示设备切换至制片人模式，用户可以通过触控控件12，控制显示设备切换至预置模式。
在一些可行性实施例中，第一提示信息可以以浮层窗口的形式展示，第二提示信息用于提示用户制片人模式开启方式，具体的可以参阅图10的界面32，从界面32中可以看出第二提示信息“显示设备新添制片人模式，切换至制片人模式可以以制片人的视角去观赏电影您可以到“图像设置”的菜单中制片人模式开关控件控制制片人模式的开启或关闭”以浮层窗口的形式展示。用户可以根据第二提示信息，在找到“图像设置”的菜单，然后，在“图像设置”的菜单中找到制片人模式菜单，通过触控制片人开关控件控制显示设备开启式或关闭制片人模式。用户可以通过触控确定控件13，控制显示器撤销第二提示信息。
在一可行性实施例中，控制器以控制显示展示第二提示信息的时间为起点，统计第二提示信息的展示时间，如果展示时间等于预置时间，控制显示器撤销第二提示信息。本实 施例中并不对预置时间作以限定，在一些可行性实施例中预置时间可以根据需求设定，例如预置时间可以为3s。
在一些可行性实施例中，控制器还被配置为：如果显示器以制片人模式展示视频帧画面，控显示器展示制片人图标，制片人图标位于视频帧画面的上层，此时，显示器的展示界面可以参阅图11的界面41。值得注意的是，图11仅是实例性的介绍一种制片人图标位于显示器中心的情况，在实际应用的过程中，可以根据需求配置制片人图标的位置，例如，在一些可行性实施例中制片人图标可以位于显示器的右上角。
在一些可行性实施例中，控制器还被配置为：统计制片人图标的展示时间；如果制片人图标的展示时间等于预置时间，控制显示器撤销制片人图标。本实施例中并不对预置时间作以限定，在一些可行性实施例中预置时间可以根据需求设定，例如预置时间可以为3s。
