相关技术中，电视节目都会在固定时间播出。用户可能对某一电视节目感兴趣，但是可能由于时间比较紧张，无法在该时间位于显示设备前观看。一般情况下，可以使用显示设备中的预约节目录制功能(PVR录制)，对感兴趣的电视节目进行预约录制，即显示设备在电视节目播放时进行自动录制。当用户时间充裕时，在将该录制的电视节目文件调出观看。但是用户经常发现，设置好的节目录制任务不能控制显示设备在预约时间到达时，自动录制电视节目，给用户带来不好的使用体验。
经过研究发现，出现上述不能自动录制电视节目的场景多为在显示设备断电后重新上电时，无法执行已经设置好的节目录制任务，即在重新上电后，当到达预约时间时，不能自动录制电视节目。这是因为，当显示设备断电后原本设置的节目录制任务，也随之丢失。所以在达到预约时间后，不执行节目录制任务对应的操作。
在一些实施例中，控制显示设备上显示PVR预约录制项目，通过该PVR预约录制项目，可以控制显示设备显示播放节目列表，该播放节目列表中显示有不同频道下的电视节目，用户可以通过该播放电视节目列表选择希望进行预设录制的电视节目。
示例性的，用户可以通过控制装置控制显示设备上显示PVR录制项目，例如，用户可以按压控制装置上的特定按键，控制显示设备上PVR录制项目，如图5所示，图5为本申请一些实施例的一种包括PVR录制项目的用户界面示意图。在一些实施例中，所述PVR录制项目可以显示在用户界面的浮层上。该浮层大小与用户界面的大小相同，该浮层除了显示PVR录制项目的位置，其余位置均为透明颜色，通过其余位置可以看到用户界面上的内容，这样可以减少PVR录制项目对用户界面上内容的遮挡。
又如，可以在显示设备的主页界面上显示有PVR录制项目，当显示设备开机时，显示设备显示主页界面，该主页界面为主页应用对应的界面。一般情况下，显示设备开机时，会自动启动主页应用，控制显示器显示主页界面。在本申请实施例中，可以当显示设备开机时，显示设备显示设置有PVR录制项目的主页界面。
需要说明的是，本申请实施例中焦点移动到项目上，可以使该项目的边框加粗，另外，也可以采用其他形式表示该项目被选中，示例性的当焦点移动到该项目上，该项目可以改变形态，可以从方形改成圆形等，也可以当项目被选中，该项目按照预设比例被放大，例如，用户界面上的视频项目的显示面积相同，当某一项目被选中后，该项目的显示面积照比原有项目的显示面积增大1.2倍。由于本申请并不对焦点位于项目上，项目的形态进行限制，所以其他可以便于用户分辨用于视频项目被选中的形式均可以被接受。
在一些实施例中，通过PVR录制项目，可以控制显示设备显示节目列表。再次参阅图5，用户可以通过控制装置将焦点移动到该PVR录制项目上，并按压控制装置上的确认键，用户界面发生变化，如图6所示，图6为本申请一些实施例的一种显示有节目列表的用户界面示意图。
在图6中显示有节目列表，该节目列表中显示有频道中播放的节目，以及节目对应的播放时长。示例性的，再次参阅图6，在图6中显示有频道1至频道3分别播放的节目1-9，以及节目播放的时长。在一些实施例中，该节目列表可以根据EPG确定。
本申请实施例中，每个频道中的节目控件可以按照从左到右的顺序排列，示例性的，如图6所示。每个频道中的节目控件还可以按照从上到下的顺序排列。本申请中对此不做具体限制，从左到右或者从上到下的排列顺序均可。
用户可以通过控制装置将焦点移动到每个节目控件上。由于用户界面的面积有限，不能将全部的频道以及频道对应的节目信息。在实际操作过程中，在图6中，用户可以将焦点移动到频道3对应的节目控件上，并按压控制装置上的下键，此时用户界面上将会将频道4对应的节目控件显示在用户界面上。示例性的，如图7所示，图7为本申请一些实施例的一种用户界面示意图，在图7中显示有频道2至频道4对应的节目控件。可以理解的是，在图7中，用户将焦点移动到频道2对应的节目控件上，并按压控制装置上的上键，此时用户界面发生变化，显示为如图6所示的用户界面，该用户界面上显示有频道1至频道3对应的节目控件。
另外，在图6中，用户可以将焦点移动到节目3控件上，并按压控制装置上的右键，此时用户界面会将节目6控件显示在用户界面上。示例性的，如图8所示，图8为本申请一些实施例的一种用户界面示意图，在图8中显示有节目6控件。可以理解的是，在图8中，用户将焦点移动到节目2控件上，并按压控制装置上的左键，此时用户界面发生变化，显示为如图6所示的用户界面，该用户界面上显示有频道1对应的节目1控件至节目3控件。
在一些实施例中，所述节目列表只显示还未播放的电视节目对应的电视控件。如果已经播放或者正在播放，可以不再显示。
在一些实施例中，所述节目列表可以显示包括已经播放，正在播放和未播放的电视节目对应的节目控件。在显示上述节目控件的同时，还可以显示指示线，该指示线可以位于当前正在播放的节目控件上。这样可以便于用户了解当前时间，确定希望进行预约录制的节目。
在图6中，每个节目存在对应的节目控件，用户可以将焦点移动到该节目控件上，并按压控制装置上的确认键，控制显示设备显示该节目对应的详细介绍内容。示例性的，用户通过控制装置将焦点移动到节目1控件上，并按压控制装置上的确认键，页面发生跳转，跳转后的用户界面如图9所示，图9为本申请一些实施例的一种包括节目对应的详细介绍内容的用户界面示意图，在图9中所述详细介绍内容可以包括节目所属频道，以及该节目的播放开始时间和结束时间，以及节目梗概。在一些实施例中，所述详细内容还包括缩略图，示例性的，该缩略图可以为预设图片，该图片可以为节目中的某一帧画面。在一些实施例中，该预设图片也可以为根据该节目的内容设定的可以表示该节目内容的图片。
在一些实施例中，所述节目梗概和缩略图可以从服务器端获取。当选中某一节目控件时，将该节目的信息和显示设备的信息一同发送到服务器，服务器根据该节目的信息，查找与其对应的节目梗概和缩略图，然后根据显示设备的信息向对应的显示设备发送查找到的节目梗概和缩略图。由于在显示设备上播放的节目众多，所以如果直接在发送节目列表的同时，将所有节目的节目梗概和缩略图均下载到显示设备中，可能会占用较大内存，所以在一些实施例中，可以采用用户在选中节目控件后，再从服务器中下载的方式，可以减少显示设备的内存占用，避免对显示设备的正常运行造成影响。
需要说明的是，本申请实施例中焦点移动到控件上，可以使该控件目的边框加粗。还可以采用其他方式表示焦点位于控件上，文中的控件和项目的变化方式相同，项目的变化方式已经在上文中介绍，因此控件的变化方式不再赘述。
在显示节目对应的详细介绍内容时，还显示有PVR录制控件和取消控件，再次参阅图9。如果用户不希望对该节目进行预约录制，则用户可以将焦点移动到取消控件上，并按 压控制装置上的确认键，用户界面重新跳转到如图6所示的用户界面上。如果用户希望对该节目进行预约录制，用户可以将焦点移动到PVR录制控件上，并按压控制装置上的确认键，用户界面发生跳转，如图10所示，图10为本申请一些实施例的一种包括显示与预约录制参数的用户界面示意图。
在图10中显示有录制起始时间控件、录制终止时间控件、确认控件和取消控件。
在一些实施例中，当用户选中PVR录制控件时，用户界面发生跳转，此时跳转后显示的预约录制参数中的录制起始时间和录制终止时间控件对应的文本框内容为空白，示例性的，如图10所示。用户可以利用控制装置将焦点移动到输入录制启示时间的文本框上，输入录制起始时间。将焦点移动到输入录制终止时间的文本框上，输入录制终止时间。
在另一些实施例中，当用户选中PVR录制控件时，用户界面发生跳转，跳转到显示预约录制参数的界面。该预约录制参数中的录制起始时间控件和录制终止时间控件对应的位置可以自动显示该节目播放开始时间和节目播放结束时间。用户可以基于自动写入的节目播放开始时间和节目播放结束时间，对应修改录制起始时间和录制终止时间。这样可以减少数字的输入量，减少用户填写录制起始时间和录制终止时间的时间。
在用户可以将希望录制的开始时间和结束时间输入到对应的控件上后，可以将焦点移动到确认控件上，并按压控制装置上的确认键。如果用户不再想对该节目进行录制，则可以将焦点移动到取消控件上，并按压控制装置上的确认键，用户界面跳转，重新显示如图9所示的用户界面示意图，或者直接调转到如图6所示的用户界面示意图，在图6中重新选择希望录制的节目控件。
上述内容包括用户设置节目录制参数的过程，当用户设置节目录制参数后，可以通过选中确认控件，示例性的，如图10所示的确认控件，生成节目录制任务。
为了解决上述的显示设备上电后，显示设备不能自动录制电视节目的问题，本申请实施例提供一种显示设备，仍参阅图3所示，该显示设备包括：显示器，用于显示来自广播系统或网络的图像，和/或，用户界面；用户输入接口，用于接收输入信号；分别与显示器和用户输入接口连接的控制器，用于执行：接收设定节目录制任务的指令，根据获取的节目录制参数生成节目录制任务，其中，节目录制任务用于控制显示设备对节目进行录制；当显示设备断电时，清除节目录制任务；在显示设备重新上电后，控制显示设备执行静默开机，并重新根据所述节目录制参数生成节目录制任务。
图11为本申请一些实施例的一种用于上述显示设备的节目数据处理方法的流程图，如图11所示，该方法在显示设备重新上电后，控制显示设备执行静默开机，根据节目录制参数生成节目录制任务，在到达预约时间，自动对电视节目进行录制，提高用户的使用体验。所述方法包括：

在一些实施例中，录制得到的数据可以存储为对应的文件，并将该文件存储在显示设备中，以供用户后续在时间充裕时对该文件的内容进行观看，这样可以避免用户由于在显示设备播放电视节目时，没有时间观看电视节目，而错过该电视节目内容，提供用户的使用体验。
示例性的，用户可以通过控制装置，控制显示设备显示设置有存储文件对应的文件控件的用户界面，示例性的，如图12所示，图12为本申请一些实施例的又一种用户界面示意图。在图12中显示有不同的存储文件对应文件控件。为了便于区分不同文件控件，可以根据生成录制文件的时间以及电视节目名称，对文件控件命名，示例性的，20xx年x月x日某时某点某分，节目名称A，将上述内容作为文件控件的名称。
一些实施例中，为了便于用户查找希望观看的录制文件，可以将同一电视节目的录制文件设置在一个文件夹中，该文件夹可以利用电视节目命名。用户选中文件夹，可以进入该文件夹对应的用户界面，该用户界面上显示有该文件夹对应电视节目中的所有录制文件，录制文件的名称可以包括录制文件的时间。
如图13所示，图13为本申请一些实施例的另一种用户界面示意图。在图13中显示有两个电视节目对应的文件夹，包括节目1和节目2。用户将焦点移动到节目1对应文件夹控件，并按压控制装置上的确认键，用户界面上显示有该节目1对应的所有录制文件，如图14所示，图14为本申请一些实施例的另一种用户界面的示意图。
S200、当显示设备断电时，清除节目录制任务；在显示设备重新上电后，控制显示设备执行静默开机，并重新根据节目录制参数生成节目录制任务。
本申请实施例中，显示设备断电可以为异常断电，也可以为正常断电。这里的异常断电可以指程序发生错误，导致显示设备未接通电源。正常断电可以指用户按照关机程序将显示设备与电源切断，示例性的，用户可以按压控制装置上的电源键，显示设备关机。在显示设备关机后，用户将显示设备的插头从供电插座拔出。
本申请实施例中，预先设置的节目录制任务一直在后台等待响应，当时间到达录制起始时间时，开始执行该节目录制任务。但是由于显示设备的程序设定，当显示设备断电时，在后台等待响应的节目录制任务，将会被清除。一旦节目录制任务清除，即使当显示设备再次上电，该节目录制任务也无法自动恢复，这就造成了显示设备不会在录制起始时间时自动执行节目录制任务的问题。
本申请实施例中，在用户设定节目录制参数后，显示设备将该节目录制参数进行保存，在显示设备上电后，显示设备执行静默开机，再次根据该节目录制参数生成节目录制任务。这样，在到达录制起始时间后仍可以执行节目录制任务，将电视节目进行录制，用户可以在空闲时观看录制文件，这样不会使用户错过希望观看的电视节目。
在一些实施例中，显示设备断电再上电后，执行静默开机，把根据存储的节目录制参数生成的节目录制任务，唤醒设置到MCU(微处理器)中。当达到录制初始时间，执行节目录制任务。从而解决相关技术中显示设备断电后节目录制任务丢失的问题，使用户获得更好的使用体验。
本申请实施例中，所述静默开机是指用户感知不到显示设备已经开机，所述显示设备 的显示器不点亮，显示设备处于静音状态，但是显示设备后台中的部分或全部程序已经启动。本申请实施例中，至少可以执行根据节目录制参数生成节目录制任务的程序被启动。
相关技术中，显示设备开机后进入正常状态。示例性的，在显示设备上电后，用户按压控制装置上的电源键，显示设备点亮显示器，并控制用户界面显示主页界面。
在本申请实施例中，显示设备开机后执行静默开机，显示设备不点亮显示设备，设置成为静音状态，即音频的播放音量为0。
本申请实施例中设置显示设备执行静默开机的原因是，一些情况下，显示设备上电后，用户只是想重启设定节目录制任务，所以点亮显示设备以及控制显示设备显示主页界面不是必要步骤。为了节约资源，所以本申请实施例控制显示设备执行静默开机。
在一些实施例中，设置有驱动程序(driver)和特定程序(agent)，利用驱动程序和特定程序，控制显示设备执行静默开机，具体的，执行静默开机的步骤，如图15所示，图15为本申请一些实施例的一种执行静默开机的流程图，所述步骤包括：
S201、控制驱动程序将静默开机标志位由原始值设置为预设值。
本申请实施例中，显示设备上电后，控制驱动程序将静默开机标志位设置为预设值。该静默开机标志位用于指示显示设备是否执行静默开机。
在一些实施例中，该静默开机标志位可以利用数字、字母和/或符号等标识。当需要执行静默开机时，将静默开机标志位由原始值改变为预设值。示例性的，所述原始值为0，所述预设值为1。当静默开机标志位为0时，不执行静默开机程序。当静默开机标志位为1时，执行静默开机程序。
需要说明的是，本申请实施例中并不限制静默开机标志位的具体表达方式和具体内容，只要能区分原始值和预设值的静默开机标志位均可。
S202、控制特定程序实时监控静默开机标志位，以使当特定程序检测到静默开机标志位为预设值时，执行静默开机。
本申请实施例中，特定程序实时监控静默开机标志位，当检测到静默开机标志为预设值时，执行静默开机。本申请实施例中，所述特定程序处于上层，所述驱动程序处于下层，通过上层和下层的配合实现执行进入静默开机。
在一些实施例中，控制驱动程序将静默开机标志位由原始值为预设值，控制特定程序实时监控静默开机标志位的步骤包括：控制驱动程序调用易方程序(eeprom)对加载器(loader)赋值，所述赋值用于将加载器中的静默开机标志为由原始值设置为初始值；控制特定程序实时监控加载器中的静默开机标志位。
本申请实施例中，利用易方程序对加载器赋值，所述特定程序实时监控加载器中的静默开机标志位。通过监控加载器中的静默开机标志位确定是否执行静默开机。
可以理解的是，由于驱动程序和易方程序之间需要传递信号或者数据等，所以在驱动程序上设置有接口，易方程序上也设置有接口，该驱动程序和易方程序通过两个接口实现信号或数据传递。同样，所述易方程序和加载器之间也设置对应的接口，易方程序和加载器通过对应的接口实现赋值等操作。
在一些实施例中，在执行静默开机后，显示器不被点亮，显示设备不会发出任何声音。该显示器不被点亮可以理解为显示设备不显示任何用户界面，即与显示设备处于关机时一样处于黑屏状态。具体的，所述方法还包括：控制电视服务(dtv服务)实时检测静默开机标志位，当检测到静默开机标志位为预设值时，不点亮显示器，以及设置显示设备处于 静音状态。本申请实施例中，在用户无感知的情况下实现显示设备静默开机，不会对用户产生任何影响。
本申请实施例中，设置显示设备处于静音状态时，即音频的播放音量为0，示例性的，为了提高用户的使用体验，可以设置开机音乐，在开机时用户可以收听开机音乐，提高使用显示设备时的乐趣。当显示设备处于静音状态时，该开机音乐不会被播放。可以理解的是，显示设备还可以设置为非静音状态，此时显示设备可以正常发出声音。
在一些实施例中，所述驱动程序调用易方程序对加载器赋值，控制电视服务检测加载器中的静默开机标志位。当加载器中的静默开机标志位为预设值，不点亮显示器，以及设置显示设备处于静音状态。本申请实施例中静默开机标志位被设置在加载器中，电视服务可以直接在加载器中查找静默开机标志位，并判断该静默开机标志位是否为预设值。如果是预设值，电视服务不执行点亮显示器，以及设置显示设备处于静音状态的操作。
在一些实施例中，在开始执行静默开机后，将所述静默开机标志位由预设值恢复至原始值。本申请实施例中，将静默开机标志位由预设值恢复至原始值，可以避免程序出现错误，对显示设备执行二次静默开机程序。如果未将预设值恢复至原始值，当检测出静默开机标志位为预设值，则仍会重复执行静默开机操作，为用户带来不好的使用体验。
示例性的，原始值为0，预设值为1。当显示设备重新上电时，将静默开机标志位从0改变为1。当检测到静默开机标志位为1时，执行静默开机操作。在开始执行静默开机后，将静默开机标志位再从1恢复至0。
在一些实施例中，在重新根据所述节目录制参数生成节目录制任务后，控制器还用于执行：控制显示设备待机。本申请实施例中为了节约资源，在生成节目录制任务后，显示设备执行待机。在一些实施例中，控制显示设备待机，可以调用gotosleep接口触发。
在一些实施例中，显示设备待机时，同样可以响应节目录制任务，即可以在到达录制起始时间时执行节目录制任务。在一些实施例中，显示设备在执行节目录制任务时，可以通过调用wakeup接口执行开机唤醒动作，将显示设备从待机中唤醒，并切换到对应的节目资源(dtv_source)及电视节目下开始录制。本申请对于录制电视节目的过程不做限制。
在一些实施例中，在显示设备处于待机时，用户可以通过控制装置发出启动指示，使显示设备处于正常开启状态，即显示器被点亮，显示主页界面。示例性的，当显示设备处于待机时，用户可以按压控制装置上的电源键生成启动指令，显示设备根据该启动指令，使显示设备开启。
在一些实施例中，在接收到取消静默开机的指令后，控制特定程序停止执行静默开机，执行普通开机程序。本申请实施例中，在显示设备执行静默开机的过程中，用户希望使用显示设备的其他功能时，可以控制显示设备停止执行静默开机，直接执行普通开机。
在一些实施例中，在显示设备执行普通开机后，仍可以自动根据节目录制参数生成节目录制任务，即在执行普通开机后，生成开机消息，显示设备根据该开机消息，根据节目录制参数生成节目录制任务。另一些实施例中，在执行普通开机后，用户可以手动重新设置节目录制参数，显示设备根据该节目录制参数，生成节目录制任务。
在一些实施例中，所述普通开机是指显示设备上电后，用户按压控制装置上的电源键后，显示设备执行的开机程序。
在一些实施例中，执行普通开机的步骤包括：显示设备的显示器被点亮，以及取消设置显示设备处于静音状态，即显示设备可以处于非静音状态播放音频。示例性的，当设置 有开机音效时，显示设备可以播放该开机音效。在一些实施例中，执行普通开机还包括：控制显示设备显示主页界面。
在一些实施例中，在接收到取消静默开机的指令后，显示设备发送screen_on广播，显示设备的显示器被点亮。
在一些实施例中，用户可以通过控制装置，生成取消静默开机的指令。示例性的，当显示设备执行静默开机的过程中，用户可以按压控制装置上的任意按键，生成取消静默开机的指令。例如，在显示设备执行静默开机的过程中，用户可以按压控制装置上的确认键，生成取消静默开机的指令。
本申请实施例中，在介绍完节目录制参数的设置方式，以及显示设备重新上电后根据节目录制参数生成节目录制任务的内容后，参照图16的示例，在启动执行该节目录制任务后，显示设备会显示节目录制界面，节目录制界面中不限于显示录制状态信息51、已录制时间52和磁盘可录制时间53、暂停控件54、结束录制控件55等。
其中，录制状态信息51不限于“录制中”、“正在录制”、“录制完成”、“录制结束”等形式；已录制时间52用于表征视频已录制的时长，是从零开始计时；磁盘可录制时间53用于表征磁盘能够支持视频录制的时长，一般与磁盘剩余可用内存和录制速度有关；用户一次触发暂停控件54，可以暂停录制进程，此时已录制时间和磁盘可录制时间暂时保持不变，用户二次触发暂停控件54时，即可解除暂停模式，从当前进度处继续后续录制。
在一些实施例中，用户触发结束录制控件55，则立即停止执行节目录制任务，参照图17的示例，将录制状态信息51由“录制中”变更为“录制结束”，并显示询问弹窗56，询问弹窗56包括询问信息561、保存控件562和第一取消控件563，询问信息561用于询问是否保存已录制的视频文件，若用户触发保存控件562，则将已录制的视频文件保存至指定的磁盘中，若用户触发第一取消控件563，则不保存已录制的视频文件。
在一些实施例中，用户在创建节目录制任务时，可以指定预约录制时长，预约录制时长是用户期望录制视频的持续时长，例如用户正在观看CCTV-6频道播放的电影A，但临时有事需要外出，预计将外出一小时，则可设置预约录制时长为1小时。参照图18的示例，用户可随时触发频道节目播放界面上设置的录制控件71，来创建对CCTV-6播放的视频的节目录制任务。
在一些实施例中，用户触发录制控件71后，显示如图19示例的录制任务设置页面，录制任务设置页面包括若干录制选项、提交控件85和第二取消控件86，录制选项不限于录制模式选项81、录制时长选项82、文件保存选项83等。
在一些实施例中，录制模式选项81用于选择立即录制模式或预约录制模式，若用户选择预约录制模式，则录制选项还包括预约起录时间选项84，预约起录时间选项84用于预约在哪一未来时间启动录制视频，时间单位涉及年月日时分，还可细化至秒；若用户选择立即录制模式，则无预约起录时间选项84，默认在节目录制任务生成时立即启动录制。
在一些实施例中，用户通过录制时长选项82来设置预约录制时长，录制时长选项82可提供若干时长选项和自定义选项，时长选项例如为15分钟、30分钟、1小时、2小时等，用户也可通过自定义选项，来输入符合其意愿的预约录制时长，例如输入45min。
在一些实施例中，文件保存选项83例如包括磁盘选项831和保存模式选项832，用户触发磁盘选项831后，根据磁盘端口的连接状态，生成并显示磁盘列表，磁盘列表中包括当前可用磁盘的相关信息，不限于磁盘名称、磁盘剩余可用内存/内存容量等信息，例如对 于“U盘，30G/64G”，表明U盘的内存容量为64G，已使用34G，剩余可用内存为30G，用户从磁盘列表中选择一个磁盘作为存储路径，来存储录制的视频文件。保存模式选项832用于开启或关闭自动保存功能，该自动保存功能是指在满足录制结束条件时自动保存视频文件，而无需显示图17示例的询问弹窗来询问是否保存已录制的视频文件。
在一些实施例中，用户设置完成各录制选项后，可触发提交控件85，则显示设备根据用户对各录制选项的设置，创建对应的节目录制任务，若为立即录制模式，则在节目录制任务创建成功时，立即执行任务；若为预约录制模式，则在系统时间达到预约起录时间时启动执行任务。若用户触发第二取消控件86，则取消创建节目录制任务，并返回图18示例的界面。
在一些实施例中，所述录制结束条件不限于用户手动触发结束录制控件55、已录制时间达到预约录制时长、已录制时间大于或等于磁盘可录制时间等。其中，已录制时间大于或等于磁盘可录制时间，表明磁盘已录满，磁盘剩余可用内存为零，已不支持继续录制视频，则需要自动停止节目录制进程，并向用户提示磁盘已录满，如图20的示例，在磁盘录满时，显示如“磁盘已录满，录制结束”的提示信息，用户查看该提示信息之后，即可获知磁盘已满，之后用户可执行如播放磁盘已录制的视频文件、切换磁盘后重新创建节目录制任务等行为操作。
在开始录制前，需要先计算出磁盘可录制时间T1，在常规的实现方式中，假设录制之前读取到磁盘剩余可用内存为R0，预设一个固定的录制速度为V0，则磁盘可录制时间T1＝R0/V0，并且磁盘可录制时间T1仅此计算一次，也就是说，磁盘可录制时间T1是静态值，节目录制界面上呈现一个固定不变的磁盘可录制时间。
然而，磁盘自身的读写能力、视频码流的分辨率等因素会影响实际录制速度，因此以固定的预设录制速度去计算磁盘可录制时间显然是不准确的，往往会出现如磁盘还有剩余可用内存但显示设备提示磁盘已满，或者磁盘已无剩余可用内存却未提示用户磁盘已满等现象，导致节目录制功能存在缺陷。为克服节目录制功能存在的技术缺陷，本申请提供一种在节目录制过程中，动态更新磁盘可录制时间的方案，并在下文中进行详细描述。
在一些实施例中，在启动录制之前，访问指定的磁盘，读取并存储磁盘初始可用内存R0，并根据预设的初始录制速度V0，计算磁盘可录制时间的初始值T1,0，即T1,0＝R0/V0。视频开始录制时，在节目录制界面上从零计时并显示已录制时间，以及显示磁盘可录制时间的初始值T1,0，系统可设置一定时器，以定时触发对磁盘可录制时间的更新，假设定时的预设时长为t1，则每间隔预设时长t1，重新计算一次磁盘可录制时间。
在一些实施例中，每间隔预设时长t1，再次读取当前的磁盘剩余可用内存R，并根据磁盘剩余可用内存R、已录制时间T2和磁盘初始可用内存R0，计算当前录制速度V，即V＝(R0-R)/T2，然后利用当前录制速度V和磁盘初始可用内存R0(V为动态变量)，计算磁盘可录制时间的更新值T1′，T1′＝R0/V，并利用更新值T1′替换节目录制界面中磁盘可录制时间的当前值T1，从而完成一次磁盘可录制时间的更新。其中，预设时长t1可以根据对磁盘可录制时间的更新频次要求进行设定，本申请不作具体限定。
在一些实施例中，参照图21～图23示例的节目录制界面，对于分辨率为1080P(蓝光清晰度)的视频码流，磁盘初始可用内存R0大约为10.4G，初始录制速度V0预设为6M/s，则开始录制时，参照图21，已录制时间T2从00:00:00开始计时，磁盘可录制时间的初始值为00:29:32；当录制一分钟后，参照图22，已录制时间T2跳至00:01:00，磁盘可录制时 间递增至00:30:27；当录制四分钟后，参照图23，已录制时间T2跳至00:04:00，磁盘可录制时间递增至00:32:16。
在一些实施例中，参照图24～图26示例的节目录制界面，对于分辨率为480P(高清清晰度)的视频码流，磁盘初始可用内存R0大约为10.4G，初始录制速度V0预设为6M/s，则开始录制时，参照图24，已录制时间T2从00:00:00开始计时，磁盘可录制时间的初始值为00:29:32；当录制一分钟后，参照图25，已录制时间T2跳至00:01:00，磁盘可录制时间递增至00:35:56；当录制四分钟后，参照图26，已录制时间T2跳至00:04:00，磁盘可录制时间递增至00:46:12。
由此可见，在磁盘相同的情况下，不同分辨率的码流具有相同磁盘可录制时间的初始值；不同分辨率的码流对应的录制速度也有显著差别，导致磁盘可录制时间的增幅和波动状态也不同，例如1080P分辨率对应的磁盘可录制时间增幅相对较小，波动较缓，而480P分辨率对应的磁盘可录制时间增幅相对较大，波动较为剧烈。本申请能够适应于不同磁盘的读写能力和不同分辨率的码流，对录制速度和磁盘可录制时间进行定时动态更新，取代常规的磁盘可录制时间的静态模式。
在一些实施例中，若创建的节目录制任务未指定预约录制时长t2，则默认可持续录制，直至磁盘被录满为止，前述实施例可知，T1′＝R0/V＝T2/(1-R/R0)，当磁盘剩余可用内存R缩减至零时，磁盘已满，此时满足T1′＝T2，因此在此录制场景中，显示设备检测到已录制时间T2大于或等于磁盘可录制时间，则需要停止执行节目录制任务，终止录制任务进程，并参照图20的示例提示磁盘已录满，若用户在设置录制选项时开启了自动保存功能，则自动保存已录制的视频文件于磁盘内。
相较于常规方式，本申请考虑到录制过程中磁盘自身读写能力以及视频码流的分辨率等因素对录制速度的影响，使磁盘可录制时间随录制速度进行自适应动态更新，保证磁盘可录制时间得以精准计算及显示，这样，在已录制时间达到磁盘可录制时间时，即认为磁盘已录满，保证磁盘内存能够被充分利用，避免显示设备提示磁盘已录满而实际上磁盘还余有可用内存，保证磁盘能被充分利用，以及，避免磁盘已无剩余可用内存但没有准确及时提示用户而导致的无效录制问题，不会对用户产生误导，从而优化节目录制功能。
在一些实施例中，若创建的节目录制任务指定有预约录制时长t2，则在节目录制进程中可能出现几种情况：情况A，磁盘尚未录满，但由于已录制时间达到用户设置的预约录制时长t2，需要停止录制；情况B，已录制时间尚未达到预约录制时长，但因磁盘已录满，磁盘内存不足以支持继续录制，导致录制任务不得不终止；情况C，已录制时间达到预约录制时长，并且此时磁盘刚好录满。
在一些实施例中，参照图27和图28示例的节目录制进程的时间轴，时间轴上有几个关键节点，分别为录制起点TS、第一节点Tstop1和第二节点Tstop2。其中，录制起点TS是启动执行节目录制任务的时间节点，录制起点TS与录制模式有关，若任务采用立即录制模式，则录制起点TS为任务创建成功并立即执行的时间；若任务采用预约录制模式，则录制起点TS为预约起录时间。第二节点Tstop2＝录制起点TS+预约录制时长t2。第一节点Tstop1＝录制起点TS+磁盘可录制时间T1，磁盘可录制时间T1是动态变量，每间隔预设时长t1会被更新一次，因此第一节点Tstop1每间隔预设时长t1沿时间轴的递增方向(图27为向右)移动，其移动呈现为离散型规律。录制进度点T＝录制起点TS+已录制时间T2，录制进度点T同样沿时间轴的递增方向(图27为向右)移动，但其移动呈现为连续型规 律。
在一些实施例中，参照图27的示例，对应于上述情况A，第二节点Tstop2在时间轴上是固定的，第一节点Tstop1是可移动的，并且其呈现为单向移动，当预约录制时长t2小于当前的磁盘可录制时间T1时，即有第二节点Tstop2小于第一节点Tstop1，则将第二节点Tstop2作为录制结束点。在检测到已录制时间T2等于预约录制时长t2时，录制进度点T行进至第二节点Tstop2处，则停止执行节目录制任务，并保存已录制的视频文件，由于该场景下节目录制结束时，录制时长达标且磁盘未满，则参照图29，以预约录制时长t2为1小时示例，只需变更录制状态信息51为“录制结束”，之后退出节目录制界面，而无需显示如磁盘已录满等提示信息。
在一些实施例中，参照图28的子图(a)，对应于上述情况B，当预约录制时长t2大于当前的磁盘可录制时间T1时，即有第二节点Tstop2大于第一节点Tstop1，则将第一节点Tstop1作为录制结束点。在检测到已录制时间T2等于当前的磁盘可录制时间T1时，录制进度点T行进至第一节点Tstop1处，则停止执行节目录制任务，并保存已录制的视频文件，由于该场景是磁盘已满，但录制时长未达到用户预期(即未达标)，因此参照图30的示例，假设预约录制时长t2为1小时，在节目录制界面中变更录制状态信息51为“录制结束”，以及显示因磁盘可用内存不足而终止录制的提示信息，之后退出节目录制界面。
由此可见，在节目录制任务中指定预约录制时长时，可将第一节点Tstop1和第二节点Tstop2中相对较小的节点作为录制结束点，从而确定哪一录制结束条件有效。也就是说，若录制进度点T先遇到第一节点Tstop1，则判定因磁盘已满而结束录制；若录制进度点T先遇到第二节点Tstop2，则判定因录制时长达标而结束录制。
在一些实施例中，参照图28的子图(b)，对应于上述情况C，若出现第一节点Tstop1、第二节点Tstop2和录制进度点T重合的情况，则录制结束时，录制时长达标并且此时磁盘刚好录满，则参照图31，以预约录制时长t2为1小时示例，在节目录制界面中变更录制状态信息51为“录制结束”，以及显示如录制成功且磁盘已录满的提示信息。
在一些实施例中，由于PVR功能是将录制文件保存在外部磁盘中，外部磁盘通过如USB等端口接入显示设备，即外部磁盘具有可插拔的使用特点，因此对于PVR功能，在启动执行节目录制任务之前，检测用户选定的磁盘是否已接入，若检测到磁盘处于已接入状态，则可读取磁盘的可用内存，进而计算磁盘可录制时间的初始值，以及对磁盘可录制时间进行动态更新，以及将录制的视频文件保存至已接入的磁盘中；若检测到磁盘处于未接入状态，则不支持PVR录制，不启动执行节目录制任务，即此次节目录制任务失败。
在一些实施例中，对于其他非PVR的录制功能，也可将录制文件保存在显示设备内置的本地磁盘中，则该磁盘默认始终处于已接入状态，在启动执行节目录制任务前可跳过检测磁盘接入状态的步骤。
在一些实施例中，磁盘中可专设有用于存储录制文件的文件夹A，已录制好的视频文件默认保存在文件夹A内，用户想要观看视频文件时，从指定路径访问磁盘，然后打开文件夹A，即可从中选择将要播放的目标视频文件。文件夹内的视频文件可按照预设规则进行排序，所述预设规则不限于按照存入磁盘的时间顺序排序等，用户还可将不感兴趣的视频文件从文件夹A中删除，以释放被占用的磁盘内存。
在一些实施例中，参照图32，本申请还提供另一种用于上述显示设备的节目数据处理方法，所述方法还由上述显示设备的控制器执行，所述方法包括：
步骤S301，启动节目录制任务时，在节目录制界面显示已录制时间、磁盘可录制时间的初始值。
步骤S302，每间隔预设时长，根据当前录制速度，对磁盘可录制时间进行更新。
步骤S303，判断已录制时间是否小于磁盘可录制时间。
其中，若否，即已录制时间大于或等于磁盘可录制时间，则执行步骤S304；反之，若是，即已录制时间小于磁盘可录制时间，则返回步骤S303，直至已录制时间大于或等于当前的磁盘可录制时间为止。
步骤S304，停止执行节目录制任务，并提示磁盘已录满。
该实施例主要针对任务中未指定预约录制时长，而是在检测到磁盘已满，无剩余可用内存时，自动触发停录机制，以避免在磁盘无存储空间的状态下维持的无效录制。通过定时动态更新磁盘可录制时间，保证磁盘可录制时间的准确性，一方面使用户能准确了解录制进度，另一方面显示设备能够精准判别磁盘是否满录。
在一些实施例中，参照图33，本申请还提供第三种用于上述显示设备的节目数据处理方法，所述方法仍由上述显示设备的控制器执行，所述方法包括：
步骤S401，在即将启动节目录制任务前，获取磁盘端口的连接状态。
其中，所述连接状态包括已接入状态和未接入状态。
步骤S402，判断磁盘是否处于已接入状态。
其中，若磁盘已接入，则执行步骤S403；若磁盘未接入，则执行步骤S4011。
步骤S403，读取并记录磁盘初始可用内存，并根据磁盘初始可用内存和预设的初始录制速度，计算磁盘可录制时间的初始值。
步骤S404，启动执行节目录制任务，在节目录制界面显示已录制时间和磁盘可录制时间的初始值。
步骤S405，判断已录制时间是否大于或等于磁盘可录制时间。
其中，若否，即已录制时间小于磁盘可录制时间，则定时循环执行步骤S406～步骤S409；反之，若是，即已录制时间大于或等于磁盘可录制时间，则执行步骤S4010。
步骤S406，每间隔预设时长，读取当前的磁盘剩余可用内存。
步骤S407，根据磁盘剩余可用内存、已录制时间和磁盘初始可用内存，计算当前录制速度。
步骤S408，根据当前录制速度和磁盘初始可用内存，计算磁盘可录制时间的更新值。
步骤S409，利用更新值替换节目录制界面中磁盘可录制时间的当前值，完成磁盘可录制时间的更新。
其中，在满足已录制时间小于磁盘可录制时间的情形下，步骤S406～步骤S409周期性地循环执行一次，周期等于预设时长t1，从而完成对磁盘可录制时间的定时动态更新，直至已录制时间大于或等于磁盘可录制时间为止。
步骤S4010，停止执行节目录制任务，并提示磁盘已录满。
步骤S4011，不启动执行节目录制任务。
图33实施例相较于图32实施例，细化了磁盘不同连接状态下的处理逻辑，以及磁盘可录制时间的初始化和定时动态更新逻辑。
在一些实施例中，参照图34，本申请还提供第四种用于上述显示设备的节目数据处理方法，所述方法仍由显示设备的控制器执行，所述方法包括：
步骤S501，在即将启动节目录制任务前，获取磁盘端口的连接状态。
其中，所述连接状态包括已接入状态和未接入状态。
步骤S502，判断磁盘是否处于已接入状态。
其中，若磁盘已接入，则执行步骤S503；若磁盘未接入，则执行步骤S5013。
步骤S503，读取并记录磁盘初始可用内存，并根据磁盘初始可用内存和预设的初始录制速度，计算磁盘可录制时间的初始值。
步骤S504，启动执行节目录制任务，在节目录制界面显示已录制时间和磁盘可录制时间的初始值。
步骤S505，每间隔预设时长，读取当前的磁盘剩余可用内存。
步骤S506，根据磁盘剩余可用内存、已录制时间和磁盘初始可用内存，计算当前录制速度。
步骤S507，根据当前录制速度和磁盘初始可用内存，计算磁盘可录制时间的更新值。
步骤S508，利用更新值替换节目录制界面中磁盘可录制时间的当前值，完成磁盘可录制时间的更新。
步骤S509，检测已录制时长是否达到目标时间。
其中，目标时间＝min{预约录制时长，当前的磁盘可录制时间}，即目标时间为预约录制时长和当前的磁盘可录制时间中的较小值，若已录制时长达到目标时间，则执行步骤S5010；反之，若已录制时长未达到目标时间，则返回步骤S509，直至已录制时长达到目标时间为止。
在已录制时长未达到目标时间的情形下，步骤S505～步骤S508周期性地循环执行一次，周期等于预设时长t1，从而完成对磁盘可录制时间的定时动态更新，直至已录制时长达到目标时间为止。
步骤S5010，判断目标时间是否为预约录制时长。
若目标时间为预约录制时长，即预约录制时长小于当前的磁盘可录制时间，则执行步骤S5011；反之，若目标时间为当前的磁盘可录制时间，即预约录制时长大于或等于当前的磁盘可录制时间，则执行步骤S5012；
步骤S5011，停止执行节目录制任务。
步骤S5012，停止执行节目录制任务，并提示因磁盘可用内存不足而终止录制。
步骤S5013，不启动执行节目录制任务。
图34实施例针对任务中指定有预约录制时长，在节目录制过程中，通过比较预约录制时长和动态更新的磁盘可录制时间，从中选择较小的目标时间作为录制结束点，检测当前录制进度是否达到录制结束点，从而决策是否触发停录机制，并且录制结束点的落点不同，导致停录机制也存在稍许差别，若录制结束点与预约录制时长关联(即预约录制时长为较小的目标时间)，则录制时长达标，只需停止录制；若录制结束点与磁盘可录制时间关联(即磁盘可录制时间为较小的目标时间)，即便录制时长未达标，但因磁盘已满，无法继续有效录制，则停止录制进程，并提示因磁盘可用内存不足而终止录制。
应当理解的是，本申请提供的UI仅仅是示例性的，具体以实际产品的设计和应用为准，节目录制任务的模式、设置、创建和执行方式，以及节目录制界面的显示和变换均不限于本申请实施例的示例。此外，还可根据实际的磁盘特性(不限于内存状态和读写能力等)和节目录制功能的配置等方面，对节目录制方案的处理逻辑进行变型和扩展。本申请 能适应于不同磁盘和视频码流的录制场景，对录制速度和磁盘可录制时间进行动态更新，计算及更新方式不限于本申请实施例的描述。
本领域技术人员可清楚地了解到本申请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。在一些实施例中，本申请还提供一种计算机可读非易失性存储介质，该计算机可读非易失性存储介质可存储有程序。当计算机可读非易失性存储介质位于显示设备200中时，该程序执行时可包括前述各实施例中任一节目录制方案所涉及的程序步骤。其中，计算机可读非易失性存储介质可为磁碟、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。
