Android电视定时任务像延迟关机、定时开机、预约录制等，一般都是通过原生闹钟管理服务(AlarmManager)设定指定时间戳来执行。当时间进行同步时，即时间戳更新后，闹钟管理服务仍按照原来的执行时间戳来执行，会造成任务提前或延后执行的问题，甚至会出现因时间戳提前量过多，导致计划任务不执行的情况。例如：用户在北京时间2022年1月1号16点0分0秒(时间戳为1641024000)时，制定30分钟后(时间戳为1641025800)关机的定时任务，此时电视时间从网络同步提前了29分钟，此时电视时间变为2022年1月1号16点29分0秒，时间戳也相应变化为1641025740，则电视将会在1分钟后关机，定时任务被提前执行，与用户预期不符。
为了解决以上技术问题，本申请实施例提供一种显示设备，显示设备的结构及各部分的功能可以参阅上述实施例。此外，在上述实施例示出的显示设备的基础上，本实施例对显示设备的一些功能做了进一步的完善。如图5所示，图5为本申请一些实施例的用户与显示设备的交互流程图。
在一些实施例中，用户在使用显示设备的过程中会根据需要设置定时任务。所述方法包括：步骤S501：输入添加定时任务的确认指令。
响应于用户输入的添加定时任务的确认指令，添加定时任务，并获取用户添加定时任务时的当前时间戳和上电时间戳，以及定时任务的计划执行时间戳(步骤S502)。
在一些实施例中，通过闹钟管理服务(AlarmManager)添加定时任务。闹钟管理服务 是android中系统自带的一个提醒服务，用来执行定时任务，当时间戳到达定时任务的执行时间时，闹钟管理服务便会执行该任务。
时间戳(timestamp)，通常是一个字符序列，唯一地标识某一刻的时间，是指格林威治时间1970年01月01日00时00分00秒(北京时间1970年01月01日08时00分00秒)起至现在的总秒数。当Android显示设备的系统时间发生变化时，显示设备的时间戳也会相应发生变化。
在一些实施例中，用户在制定定时任务时，通过System.currentTimeMillis()(当前时间戳获取接口)获取添加定时任务时的当前时间戳，并计算定时任务计划执行的时间戳，通过SystemClock.elapsedRealtime()(上电时间戳获取接口)获取添加定时任务时的上电时间戳。
在一些实施例中，添加定时任务时的当前时间戳具体是指用户在输入添加定时任务的确认指令时系统时间显示的时间戳，添加定时任务时的上电时间戳具体是指从显示设备上电开始至用户在输入添加定时任务确认指令时的时间戳。定时任务的计划执行时间戳是以当前显示的系统时间为准计算得到定时任务的计划执行时间戳。需要说明的是，显示设备上电是指显示设备接入电源，当前显示设备的状态包括正常工作状态、睡眠状态和待机状态。
例如：用户在输入添加定时任务的确认指令的时间为2022年1月1日9：00：00；显示设备上电的时间为2022年1月1日8：00：00；用户设置的定时任务执行时间为2022年1月1日10：00：00，那么添加定时任务时的当前时间戳为1640998800，添加定时任务时的上电时间戳3600，定时任务的计划执行时间戳为1641002400。
步骤S503：监听定时任务是否执行。
在一些实施例中，以定时关机为例，用户设置在30分钟后关机，可持续或定时监听显示设备是否关机；如果显示设备已关机，说明定时任务已执行，则不执行任何操作；如果显示设备未关机，说明定时任务未执行，监听单位时间内系统时间变化值是否超过预设值(S504)，若是，则执行步骤S505，若否，则执行步骤S503。
在一些实施例中，显示设备上的系统时间随着时间推移一直在变化，但是如果单位时间内系统时间变化值超过预设值，说明系统时间被用户手动修改或同网络时间同步对其进行了修改。
在一些实施例中，通过注册Intent.ACTION_TIME_CHANGED(时间变化)广播接收器实现监听显示设备的系统时间是否变化或是单位时间内系统时间变化值超过预设值。
在一些实施例中，显示设备的系统时间同步或修改可通过时间设置页面进行设置。图6为本申请一些实施例的时间设置页面的示意图。参阅图6所示，时间设置页面包括自动确定日期和时间控件61、设置日期控件62、设置时间控件63、设置时区控件64和使用24小时制控件65，所述页面还包括指示任一控件被选择的选择器66。当前选择器66指示自动确定日期和时间控件61被选择，用户可按压控制装置的确认键，响应于用户输入的指令，显示如图7所示的页面。图7为本申请一些实施例的自动确定日期和时间页面的示意图。图7所示的页面包括使用网络提供的时间控件71、关闭控件72和指示任一控件被选择的选择器73。用户如果选中使用网络提供的时间控件71，如图8所示，可自动从网络同步时间且用户不能自行修改系统时间。在图6中，用户选中设置时间控件63，用户可手动修改系统时间。
需要说明的是，选择器用于指示其中任一控件已被选择，如焦点对象。一方面，可根据用户通过控制装置的输入，控制显示设备中显示焦点对象的移动来选择或控制控件。如：用户可通过控制装置上方向键控制焦点对象在控件之间的移动来选择和控制控件。另一方面，可根据用户通过控制装置的输入，控制显示设备中显示的各控件的移动来使得焦点对象选择或控制控件。如：用户可通过控制装置上方向键控制各控件一并进行左右移动，以在保持焦点对象的位置不变时使得焦点对象选择和控制控件。
选择器的标识形式通常多样化。示例的，通过放大控件来实现或标识焦点对象的位置，通过设置控件背景色来实现或标识焦点对象的位置，也可以通过改变聚焦控件的文本或图像的边框线、尺寸、颜色、透明度和轮廓和/或字体等标识焦点对象的位置。
在一些实施例中，所述单位时间内系统时间变化值超过预设值，包括：用户手动设置系统时间时，单位时间内系统时间变化值超过预设值。例如：当前显示设备的系统时间上午8:00:00，用户将系统时间手动修改为8:30:00，单位时间为1S，预设值为1S。也就是说，在1S后，系统时间应该为8:00:01，但是系统时间却为8:30:00，变化值超过1S。
在一些实施例中，所述单位时间内系统时间变化值超过预设值，包括：通过网络同步系统时间后，单位时间内系统时间变化值超过预设值。例如：当前显示设备的系统时间上午8:00:00，网络同步时间后修改为8:00:30，单位时间为1S，预设值为1S。也就是说，在1S后，系统时间应该为8:00:01，但是系统时间却为8:00:30，变化值超过1S。
在一些实施例中，如果在执行步骤S503，监听定时任务是否执行时，确定定时任务未执行，处理器还可以执行步骤：监听用户是否手动修改系统时间或网络时间是否同步，以代替步骤S504。具体实施中，如果监听用户输入手动修改系统时间的指令或网络时间进行同步，执行步骤S505；如果未监听用户输入手动修改系统时间的指令和网络时间进行同步，处理器执行步骤S503。
步骤S505：获取第一系统时间变化后的当前时间戳和上电时间戳。
在一些实施例中，通过System.currentTimeMillis()(当前时间戳获取接口)获取第一系统时间变化后的当前时间戳，通过SystemClock.elapsedRealtime()(上电时间戳获取接口)获取第一系统时间变化后的上电时间戳。
在一些实施例中，第一系统时间变化后的当前时间戳具体是指第一次用户修改后或网络同步后的系统时间戳，第一系统时间变化后的上电时间戳具体是指从显示设备上电开始至第一次用户修改时间或网络同步时间的时间戳。
步骤S506：根据添加定时任务时的当前时间戳和上电时间戳，以及定时任务的计划执行时间戳，以及第一系统时间变化后的当前时间戳和上电时间戳，计算第一系统时间变化后的定时任务执行时间戳。
在一些实施例中，添加定时任务时的当前时间戳和上电时间戳，以及所述定时任务的计划执行时间戳，以及第一系统时间变化后的当前时间戳和上电时间戳，计算第一系统时间变化后的定时任务执行时间戳的步骤，具体包括：根据添加定时任务时的当前时间戳和上电时间戳，以及，所述第一系统时间变化后的当前时间戳和上电时间戳，计算第一系统时间变化量；根据所述定时任务的计划执行时间戳和所述第一系统时间变化量，计算第一系统时间变化后的定时任务执行时间戳。
本申请实施例中，第一系统时间变化后的定时任务执行时间戳的计算方法，具体包括：添加定时任务时的当前时间戳A1和上电时间戳B1，以及，第一系统时间变化后的当前时 间戳A2和上电时间戳B2，计算第一系统时间变化量C1：C1＝(A2-A1)-(B2-B1)。
在一些实施例中，第一系统时间变化量C1＝(第一时间变化后的当前时间戳A2与上电时间戳B2的差值)-(添加定时任务时的当前时间戳A1与上电时间戳B1的差值)；即C1＝(A2-B2)-(A1-B1)。
然后，根据定时任务的计划执行时间戳P1和第一系统时间变化量C1，计算第一系统时间变化后的定时任务执行时间戳P2：P2＝P1+C1。
例如：添加定时任务时的当前时间戳A1为1640998800(2022年1月1日9：00：00)，添加定时任务时的上电时间戳B1为3600，定时任务的计划执行时间戳P1为1641002400(2022年1月1日10：00：00)；第一系统时间变化后的当前时间戳A2为1641000600(2022年1月1日9：30：00)和上电时间戳B2为5000；第一系统时间变化量C1＝(A2-A1)-(B2-B1)＝(1641000600-1640998800)-(5000-3600)＝400；第一系统时间变化后的定时任务执行时间戳P2＝P1+C1＝1641002400+400＝1641002800(2022年1月1日10：06：40)。
步骤S507：根据第一系统时间变化后的定时任务执行时间戳更新定时任务的计划执行时间戳。
在一些实施例中，在执行步骤S506计算得到第一系统时间变化后的定时任务执行时间戳后，执行步骤S507，通知闹钟管理服务(AlarmManager)将第一系统时间变化后的定时任务执行时间戳更新到定时任务的计划执行时间戳。
步骤S508：检测当前显示设备是否是工作状态。
在一些实施例中，在执行步骤S508时，具体包括：检测当前显示设备的显示屏幕是否开启。如果显示屏幕开启，说明当前显示设备处于工作状态，用户正在使用显示设备，则执行步骤S509；如果显示设备的显示屏幕未开启，说明当前显示设备处于睡眠状态或待机状态，则不执行任何操作。
步骤S509：控制显示器显示信息提示框。其中，信息提示框用于提示用户系统时间已更新，信息提示框还用于提示所述系统时间更新后定时任务的执行时间。
在一些实施例中，定时任务执行时间戳精确到秒，但是用户不需要知道太具体的时间，在显示更新后定时任务的执行时间可只显示到分钟即可。例如：定时任务精确执行时间为8：12：34，信息提示框定时任务的执行时间为8：12。
图9为本申请一些实施例的系统时间已更新提示页面的示意图。图9所示的页面包括信息提示框91，信息提示框91包括提示信息，提示信息可以是系统时间已更新，定时任务将在XX：XX执行。信息提示框宽高小于显示屏幕的宽高；信息提示框可设置在用户界面的任意位置；系统时间已更新提示页面中非信息提示框得部分设置成透明或半透明状态，以避免遮挡住原来的用户界面。在系统时间已更新提示页面显示预设时长后，取消显示系统时间已更新提示页面。
在一些实施例中，当系统显示时间到达定时任务的计划执行时间戳后，处理器执行对应的定时任务。
在一些实施例中，用户在添加定时任务至执行定时任务的过程中，可能涉及不止一次的系统时间变化，定时任务计划执行时间戳更新方法，在步骤S507或步骤S509后，还可包括以下步骤：
记录第一系统时间变化后的当前时间戳和上电时间戳；
判断定时任务是否执行；
如果定时任务未执行，判断单位时间内系统时间变化值是否超过预设值；
如果单位时间内系统时间变化值超过预设值，获取第二系统时间变化后的当前时间戳和上电时间戳；
根据第一系统时间变化后的当前时间戳和上电时间戳，所述定时任务的计划执行时间戳，以及第二系统时间变化后的当前时间戳和上电时间戳，计算第二系统时间变化后的定时任务执行时间戳；
根据所述第二系统时间变化后的定时任务执行时间戳更新所述定时任务的计划执行时间戳。
判断当前显示设备是否是工作状态；
如果当前显示设备是工作状态，控制显示器显示信息提示框。
在一些实施例中，第一系统时间变化后的当前时间戳A2、上电时间戳B2和定时任务的计划执行时间戳P2；第二系统时间变化后的当前时间戳A3和上电时间戳B3。
根据第一系统时间变化后的当前时间戳A2和上电时间戳B2，以及第二系统时间变化后的当前时间戳A3和上电时间戳B3，计算第二系统时间变化量C2；即C2＝(A3-A2)-(B3-B2)。
根据第一系统时间变化后的定时任务执行时间戳和第二系统时间变化量，计算第二系统时间变化后的定时任务执行时间戳P3；即P3＝P2+C2。
例如：第一系统时间变化后的当前时间戳A2为1641000600(2022年1月1日9：30：00)和上电时间戳B2为5000，定时任务的执行时间戳P2为1641002800(2022年1月1日10：06：40)；第二系统时间变化后的当前时间戳A3为1641001200(2022年1月1日9：40：00)和上电时间戳B3为5200；第二系统时间变化量(A3-A2)-(B3-B2)＝(1641001200-1641000600)-(5200-5000)＝400；第二系统时间变化后的定时任务执行时间戳P3＝P2+C2＝1641002800+400＝1641003200(2022年1月1日10：13：20)。
在一些实施例中，记录第二系统时间变化后的当前时间戳和上电时间戳，以便当再次发生系统时间改变时计算定时任务的执行时间。
在一些实施例中，用户在添加定时任务至执行定时任务的过程中，可能涉及不止一次的系统时间变化，定时任务执行时间戳更新方法，在步骤S507或步骤S509后，处理器执行以下步骤：
记录添加定时任务时定时任务的计划执行时间戳；
判断定时任务是否执行；
如果定时任务未执行，判断单位时间内系统时间变化值是否超过预设值；
如果单位时间内系统时间变化值超过预设值，获取第二系统时间变化后的当前时间戳和上电时间戳；
根据添加定时任务时的当前时间戳和上电时间戳，添加定时任务时定时任务的计划执行时间戳，以及第二系统时间变化后的当前时间戳和上电时间戳，计算第二系统时间变化后的定时任务执行时间戳；
根据所述第二系统时间变化后的定时任务执行时间戳更新所述定时任务的计划执行时间戳。
判断当前显示设备是否是工作状态；
如果当前显示设备是工作状态，控制显示器显示信息提示框。
在一些实施例中，添加定时任务时的当前时间戳A1、上电时间戳B1和添加定时任务时定时任务的计划执行时间戳P1；第二系统时间变化后的当前时间戳A3和上电时间戳B3。
根据添加定时任务时的当前时间戳A1和上电时间戳B1，以及第二系统时间变化后的当前时间戳A3和上电时间戳B3，计算第二系统时间变化量C2；即C2＝(A3-A1)-(B3-B1)。
根据添加定时任务时的定时任务计划执行时间戳和第二系统时间变化量，计算第二系统时间变化后的定时任务执行时间戳P3；即P3＝P1+C2。
例如：添加定时任务时的当前时间戳A1为1640998800(2022年1月1日9：00：00)，添加定时任务时的上电时间戳B1为3600，添加定时任务时定时任务的计划执行时间戳P1为1641002400(2022年1月1日10：00：00)；第二系统时间变化后的当前时间戳A3为1641001200(2022年1月1日9：40：00)和上电时间戳B3为5200；第二系统时间变化量C2＝(A3-A1)-(B3-B1)＝(1641001200-1640998800)-(5200-3600)＝800；第二系统时间变化后的定时任务执行时间戳P3＝P1+C2＝1641002400+800＝1641003200(2022年1月1日10：13：20)。
在一些实施例中，上述定时任务包括定时开机、定时关机和预约录制。下面对不同定时任务类型进行举例说明。
实施例一：定时开机
用户可以通过打开设置页面，在设置页面中选择高级设置，打开高级设置页面后选择计时后，打开计时页面。图10为本申请一些实施例的计时页面的示意图。图10所示的页面包括定时关机控件101、自动定时开机模式控件102、自动开机时间控件103、自动定时关机模式控件104，所示页面还包括指示任一控件被选择的选择器105，图10所示的页面还包括指示任一控件被选择的选择器106。
当用户选中自动定时开机模式控件102并开启定时开机模式(仅一次)，同时选中自动开机时间控件后，响应于用户的指令，显示如图11所示页面，图11为本申请一些实施例的自动开机时间设置页面的示意图。用户可在图11中设置自动开机时间。如果在用户关机(显示设备待机)前系统时间发生变化(如用户手动修改系统时间或网络时间同步)，计算并更新系统时间发生变化后的自动开机时间，并提示用户系统时间已更新，以及告知定时开机任务的最新执行时间，如图12所示。图12为本申请一些实施例的自动开机时间提醒页面的示意图。如果在用户关机(显示设备待机)后系统时间发生变化(网络时间同步)，计算并更新系统时间发生变化后的自动开机时间。
实施例二：定时关机
用户可以通过打开设置页面，在设置页面中选择高级设置，打开高级设置页面后选择计时后，打开计时页面。图10是一实施例的计时页面的示意图。图10所示的页面包括定时关机控件101、自动定时开机模式控件102、自动开机时间控件103、自动定时关机模式控件104，所示页面还包括指示任一控件被选择的选择器105。
当用户选中定时关机控件101后，响应于用户的指令，显示如图13所示页面，图13为本申请一些实施例的定时关机时间设置页面的示意图。用户可在图13中设置延时关机的时间。当系统时间发生变化(如用户手动修改系统时间或网络时间同步)，计算并更新系统时间发生变化后的延时关机时间，并提示用户系统时间已更新，以及告知定时关机任务的最新执行时间，如图14所示。图14为本申请一些实施例的自动关机时间提醒页面的示意图。
实施例三：预约录制
用户可以在显示设备显示的首页中打开信号源页面。图15为本申请一些实施例的信号源选择页面的示意图。用户在图15中选择TV控件151进入Live TV应用程序，观看电视有线信号。
用户可通过按压控制装置的录制键或在频道播放页面下通过控制装置调出如图16所示的菜单栏，在菜单栏中选中录制控件161，进入预约录制设置页面。图17为本申请一些实施例的预约录制设置页面的示意图。图17所示的页面包括录制模式控件171、开始时间控件172、结束时间控件173、频率控件174、保存控件175和取消控件176，所示的页面还包括指示任一控件被选择的选择器177。
用户在设置完预约录制的开始时间和结束时间后，选中保存控件即可完成预约录制的设置。需要说明的是，预约录制包含两个执行时间。所以在系统时间变化时需要对两个执行时间戳进行计算。如果在用户关机(显示设备待机)前系统时间发生变化(如用户手动修改系统时间或网络时间同步)，计算并更新系统时间发生变化后的预约录制的开始时间和结束时间，并提示用户系统时间已更新并告知预约录制任务的最新执行时间，如图18所示。图18为本申请一些实施例的预约录制时间提醒页面的示意图。如果在用户关机(显示设备待机)后系统时间发生变化(网络时间同步)，计算并更新系统时间发生变化后的预约录制的开始时间和结束时间。
这样，本申请实施例通过计算系统时间变化后时间戳变化量来自动调节定时任务的执行时间戳，避免任务提前执行或延后执行的情况；自动调节任务时间戳时，还提示用户该任务时间点已更新，并告知任务最新时间点，具有更好的用户体验；同时，也不会出现因时间变化量提前过大，原定延迟任务已不满足条件未执行的情况。
由于前述显示设备具有预约录制功能，因此，在用户使用预约录制功能创建视频录制任务时，可设置目标时长，显示设备检测达到录制起始时间，启动视频录制任务，并在录制时长达到目标时长，或者用户主动结束录制时，停止执行视频录制任务。然而，在此时段内，录制的视频文件可能包含同一频道内的多个连播节目，用户对每个节目的兴趣偏好不同，这样，就导致用户在回看录像文件时，需要先跳过不感兴趣的节目片段，才能从一个长视频文件中逐渐定位到感兴趣的节目的位置，从而给用户带来不便。
相关技术下，与前述显示设备相同或相似的终端可配置录像功能，录制显示设备播放的节目视频，并将录像文件保存在指定的磁盘路径，例如保存于显示设备的本地磁盘或者外部磁盘内，所述外部磁盘可连接显示设备，实现读写功能，外部磁盘不限于U盘、移动硬盘、读卡器等，用户可以随时回看已录制的视频文件，可进行快进、seek(即搜寻，用于快速搜寻及定位至视频文件的某一播放位置处)和反复多次播放等操作，也可将录像文件从磁盘中删除，以释放被占用的存储空间。显示设备一般配置有连接外部磁盘的接口，不限于连接U盘、移动硬盘的USB接口等。
在一些实施例中，显示设备接收TV码流后，对TV码流进行处理后显示于显示器，从而向用户呈现电视节目画面，用户可以切换频道，观看不同频道下的节目内容。在启动执行视频录制任务后，显示设备缓存录制时段内接收的码流数据，直至录制结束时，对已缓存的码流数据进行格式转换，即转换为视频格式(例如mp4、avi等)，从而生成并保存录像文件至指定磁盘内。
在一些实施例中，参照图19的示例，在节目播放界面上可设置录像控件51，用户通 过遥控器或屏幕触控等方式触发录像控件51，即可启动录像功能。
在一些实施例中，控制装置100(例如遥控器)上可设置录像按键，该按键相当于遥控端启动录像功能的快捷键，在显示设备播放电视节目过程中，用户可随时点击控制装置100上的录像按键，控制装置100响应于录像按键被触发，向显示设备端发送控制指令；显示设备解析该控制指令，读取键值后，即可获知用户意图为启动录像功能。
在一些实施例中，若显示设备支持语音功能，如图20示例的语音交互场景，在显示设备播放电视节目时，用户对显示设备说出“我要录像”，显示设备采集该语音信息后，对语音信息进行解析处理，例如进行关键词提取、语义处理等，即可获知用户的语音意图是启动录像功能。
在一些实施例中，响应于用户启动录像功能的意图指令，显示如图21示例的录制任务设置页面，该页面中具有录制模式设置控件211、第一确认控件212、第一取消控件213和磁盘选择控件214，用户通过录制模式设置控件211来选择期望的录制模式。
在一些实施例中，录制模式包括但不限于按时间录制模式和按节目录制模式。参照图21，用户选择按时间录制模式后，录制任务设置页面中显示时间设置控件2111，用户通过时间设置控件2111来设定启动时间T0和停止时间TS，启动时间T0和停止时间TS的差值即为预设录制时长，之后用户触发第一确认控件212，则处理器根据启动时间T0和停止时间TS，创建对应于按时间录制模式的视频录制任务。
在一些实施例中，用户触发磁盘选择控件214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，包括但不限于磁盘名称、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，用户从磁盘列表中择一磁盘作为预设存储器，来存储录像文件。
在一些实施例中，参照图22，用户选择按节目录制模式后，触发第一确认控件212，则处理器根据EPG(Electrical Program Guide，电子节目指南)，查询当前的节目信息，节目信息包括节目名称和节目播放起止点，其中节目名称用于指示哪一频道的哪个节目，节目播放起止点用于指示节目的开播时间和播放截止时间，处理器根据当前节目信息创建对应于按节目录制模式的视频录制任务。
在一些实施例中，如图21和图22所示，无论用户是否选择录制模式，若用户触发第一取消控件213，均不创建视频录制任务，返回图19示例的节目播放界面。
在一些实施例中，若采用按时间录制模式，处理器若检测到系统时间达到视频录制任务的启动时间T0，则启动执行视频录制任务，显示设备会显示视频录制界面，如图23的示例，视频录制界面中不限于显示录制状态提示信息221、已录制时间222、磁盘可录制时间223、暂停控件224、停止录制控件225和进度条226等，实现“边播边录”。
在一些实施例中，录制状态提示信息221例如呈现为“录制中”、“正在录制”、“录制完成”、“录制结束”等状态提示；已录制时间222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223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、录制速度、码流分辨率等因素有关；用户一次触发暂停控件224，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224时，即可解除暂停模式，从当前进度处继续后续录制；进度条226用于表征录制进程，以及方便用户识别磁盘是否录满。
在一些实施例中，若录制模式选择按时间录制，则在检测到系统时间达到视频录制任务的停止时间TS，立即停止执行视频录制任务；或者，无论录制模式选择按时间录制还是按节目录制，若用户主动触发停止录制控件225，都要立即停止执行视频录制任务。
在一些实施例中，处理器响应于停止录制指令，停止执行视频录制任务，即停止继续缓存码流数据，显示设备的状态由“边播边录”切换为“仅播不录”，参照图24的示例，将录制状态提示信息221由“录制中”变更为“录制结束”，并显示第一询问弹窗227，第一询问弹窗227中包括第一询问信息2271、第一保存控件2272和第一取消控件2273，第一询问信息2271用于询问是否保存录像文件，若用户触发第一取消控件2273，则删除缓存的码流数据，不保存本次录制的视频文件；若用户触发第一保存控件2272，则将录像文件保存至指定的磁盘中，方便用户访问磁盘后回看录像文件。
在一些实施例中，若采用按节目录制模式，则立即启动执行视频录制任务，显示设备会显示如图23示例的视频录制界面，直至检测到系统时间达到当前节目的播放截止时间，或者直至用户主动触发停止录制控件225，停止执行视频录制任务，并按照图24的示例询问是否保存录像文件。
在一些实施例中，按时间录制模式和按节目录制模式是相互独立且不兼容的，用户在创建视频录制任务时必须选定一种录制模式。对于按时间录制模式，虽然支持用户任意、灵活地设置启动时间T0和停止时间TS，但如果录制时间较长，会导致录像文件的数据量较大，录制时段内显示设备可能播放多个节目，参照图25的示例，假设用户创建的视频录制任务中，启动时间T0为19:00，停止时间TS为20:00，处理器检测到系统时间达到19:00时，启动执行视频录制任务，开始缓存码流数据，直至检测到系统时间达到20:00时停止录制，在19:00～20:00的录制时段内，边播边录的节目包括连播的节目A、节目B和节目C，其中节目A的播放时长为30分钟，节目B的播放时长为5分钟，节目C的播放时长为25分钟，即节目A的播放起止点为19:00和19:30，节目B的播放起止点为19:31和19:35，节目C的播放起止点为19:36和20:00。
在图25示例的录制场景中，处理器在检测到系统时间达到停止时间TS为20:00时，停止执行视频录制任务，并按照图24方式询问是否保存录像文件，若接收到用户输入的保存指令，处理器会保存时长为1小时的整段录像文件，该录像文件包含从19:00～20:00这一时段内播放的三个节目视频，而用户对每个节目的兴趣偏好不同，往往需通过播放进程的自然推进、或者通过快进、seek等繁琐操作，才能从一段长录像文件中定位自己喜爱的节目片段。例如用户对节目A不感兴趣，可以先观看节目A，直至播放进程自然推进至第31分钟，从而继续观看感兴趣的节目B，或者，用户通过快进或seek等操作将播放进度快速跳转至第31分钟，从而加快跳过不感兴趣的节目A。
因此，一方面用户想要从包含多节目的长录像文件中定位感兴趣的节目位置，尤其对于数据量和时长较大的录像文件，这一目的在实现时可能耗时长、操作繁琐；另一方面，长录像文件里可能包含一个或多个用户不感兴趣的节目视频，会浪费磁盘存储空间；此外，如图26的示例，按时间录制模式结束时，处理器响应于用户输入的保存指令，查询录制期间显示设备播放的频道信息，按时间录制模式下默认以频道名称命名录像文件，并将包含至少一个节目视频的录像文件存入预设存储器内，预设存储器为保存录像文件的磁盘，例如本机磁盘、U盘、移动硬盘等，例如图26中录像文件1和录像文件2均是以频道1命名，用户难以分辨自己想要回看的是录像文件1还是录像文件2。
在一些实施例中，如图27的示例，按节目录制模式结束时，处理器响应于用户输入的保存指令，查询录制期间显示设备播放的节目信息，按节目录制模式下默认以节目名称命名录像文件，并将仅包含一个节目视频的录像文件存入预设存储器内，此场景下录像文件的辨识度高，便于用户快速查找想要回看的节目视频。但按节目录制模式每次仅能够录制一个节目视频，若要录制多个节目视频，必须提前预约多个视频录制任务，不便于用户使用。
在一些实施例中，为克服按时间录制模式和按节目录制模式存在的弊端，本申请提供一种按时间录制与按节目保存模式相融合的方案，按照前述流程创建并执行按时间录制模式下的视频录制任务，处理器在检测到系统时间达到停止时间TS，或者用户主动触发停止录制控件225时，响应于停止录制指令，停止执行视频录制任务，处理器基于启动时间T0和停止时间TS限定的录制时段，从EPG功能中查询录制时段内显示设备的节目播放信息，节目播放信息包括N个节目信息，N大于或等于1，所述节目信息包括节目名称和节目播放起止点，然后根据节目播放信息，确定录像文件的目标保存模式，并按照目标保存模式，将录像文件存入预设存储器内。
在一些实施例中，按照前述流程，用户触发图24中的第一保存控件2272，则处理器响应于该保存指令，若查询到N等于1，即在录制时间内仅录制一个节目视频，自动以整段保存模式，将录像文件存入预设存储器内。整段保存模式被配置为，不分割录像文件，根据查询到的录制时段内显示设备播放的频道，以频道名称对录像文件进行命名，将整段录像文件存入预设存储器内。
在一些实施例中，按照前述流程，用户触发图24中的第一保存控件2272，则处理器响应于该保存指令，若查询到节目播放信息包含多个节目信息，即N大于1，如图28的一种示例，在用户界面上显示第一保存模式询问弹窗241，第一保存模式询问弹窗241包括第一提示信息242、第一模式控件243和第二模式控件244。其中，第一提示信息242用于提示用户选择一种录像文件的保存模式；第一模式控件243被触发时，处理器以整段保存模式，将录像文件存入预设存储器内，即不按节目对录像文件进行分割，整段录像文件中包含N个节目视频。
在一些实施例中，第二模式控件244被触发时，处理器以按节目保存模式，将录像文件存入预设存储器内，所述按节目保存模式配置为，根据每个节目信息指示的节目播放起点为Ti_1和节目播放止点为Ti_2，其中i表示按播放时序对录制时段内的节目排序后的节目序号，1≤i≤N，将录像文件分割为N个节目录制子文件，并按照节目名称分别对N个节目录制子文件进行命名，然后将N个节目录制子文件存入预设存储器内。
在一些实施例中，处理器响应于对第二模式控件244的触发指令，参照图29的子图(a)，根据EPG功能查询到[启动时间T0，停止时间TS]这一录制时段内，按时序连播3个节目(即N＝3)，依次为节目A、节目B和节目C，节目A的播放起止点分别为T1_1和T1_2，节目B的播放起止点分别为T2_1和T2_2，节目C的播放起止点分别为T3_1和T3_2，基于同一频道内多个节目在时间上的播放连续性，相邻两个节目的止点和起点重合，即满足T0等于T1_1，T1_2等于T2_1，T2_2等于T3_1，T3_2等于TS，因此根据T1_1和T1_2从整段录像文件中分割出节目A对应的子文件一，根据T2_1和T2_2从整段录像文件中分割出节目B对应的子文件二，根据T3_1和T3_2从整段录像文件中分割出节目C对应的子文件三。如图29的子图(b)，在预设存储器中分别保存子文件一、子文件二和子文件三， 其中，子文件一被命名为节目A的名称，子文件二被命名为节目B的名称，子文件三被命名为节目C的名称，其中节目名称可包含频道名称，例如节目名称为频道1-节目A，或者也可仅呈现为节目A，不包含频道名称。
在一些实施例中，如图30所示的节目播放/录制时间轴，在T0时间节点处，处理器启动执行视频录制任务，开始缓存码流数据，在T1_2时间节点处节目1录制截止，继续录制下一节目，以此类推，在Ti_1时间节点处开始录制节目i，在Ti_2时间节点处节目i录制截止，当系统时间达到TS时间节点时，停止执行视频录制任务，从T0到TS之间的录制时段，录制进程遍历N个节目，在时间轴上N个节目信息是按照按播放时序进行排序，其中排序在首位的初始节目信息(即节目1)对应的节目播放起点为T1_1和节目播放止点为T1_2，排序在末位的截止节目信息(即节目N)对应的节目播放起点为TN_1和节目播放止点为TN_2，参照图30，若T0大于T1_1，说明视频录制任务启动时，节目1已播过一部分视频片段，则将T0作为节目1的录制起点，根据T0和T1_2分割出节目1的子文件1，此场景下节目1录制不完整；若TS小于TN_2，说明视频录制任务结束时，节目N尚未播放结束，则将TS作为节目N的录制止点，根据TN_1和TS分割出节目N的子文件N，该场景下节目N录制不完整。其他的节目2～节目N-1均能保证完整录制。
按时间录制模式+按节目保存模式，能兼容按时间录制模式和按节目录制模式的优点，用户可以灵活设置视频录制任务的启停时间，并且支持录制时段内连续录制多个节目视频，该方案以单独节目为单位进行录像文件的分割和存储，用户在访问预设存储器后，能够快速查找感兴趣的节目视频，以及删除不感兴趣的节目视频，从而避免磁盘存储空间的浪费。
在一些实施例中，按照前述流程，用户触发图24中的第一保存控件2272，则处理器响应于该保存指令，若查询到节目播放信息包含多个节目信息，即N大于1，如图31的另一种示例，在用户界面上显示第二保存模式询问弹窗170，第二保存模式询问弹窗170包括第二提示信息171、同意控件172和拒绝控件173，第二提示信息171用于询问是否同意采用按节目保存模式，图17中第二提示信息171示例为“是否同意按节目保存录像文件？”，若用户触发同意控件172，处理器响应于同意指令，以按节目保存模式来保存录像文件；若用户触发拒绝控件173，处理器响应于拒绝指令，以整段保存模式来保存录像文件。
在一些实施例中，处理器响应于停止录制指令，若查询到节目播放信息包含多个节目信息，即N大于1，则在用户界面上显示如图32示例的第三保存模式询问弹窗180，第三保存模式询问弹窗180包括第一保存模式控件181、第二保存模式控件182和不保存控件183，第一保存模式控件181对应于整段保存模式，第二保存模式控件182对应于按节目保存模式。若用户触发不保存控件183，则删除录制时段内缓存的码流数据，不保存录像文件；若用户触发第一保存模式控件181和第二保存模式控件182中的任意一个，就需要按照模式控件对应的保存模式，保存本次的录像文件。该实施例中在停止执行视频录制任务时，无需先询问是否保存录像文件、而后再选择目标保存模式，而是将两者集中呈现于同一弹窗页面中，简化UI及用户操作。
在一些实施例中，若录像文件内包含多个连播的节目视频，由于用户对每个节目的兴趣偏好不同，用户更期望保留自己感兴趣的节目视频，滤掉或删除自己不偏好的节目视频，对此，用户在图28、图31和图32示例的保存模式询问弹窗中选择按节目保存模式后，处理器控制显示器关闭保存模式询问弹窗，并在用户界面上显示如图33示例的节目保存页 面190，在节目保存页面190中向用户呈现已录制的N个节目的节目信息，这里所述的节目信息至少应包括节目名称，以便用户辨别和筛选。用户可根据自身的兴趣偏好，从N个节目信息中选定M个目标节目信息，M个目标节目信息组成第一节目集合，0≤M≤N，其余M-N个未被选定的节目信息组成第二节目集合。第一节目集合用于指示用户感兴趣的、期望留存的节目，第二节目集合用于指示用户不感兴趣的、不想保存的节目。
在一些实施例中，参照图33，节目保存页面190中每个节目信息对应于一个选择控件191，选择控件191处于选择状态时，其对应的节目信息被选定。节目保存页面190中还包括第二确认控件192和第二取消控件193。
在一些实施例中，若用户未选定任何节目信息，即空选后触发第二确认控件192，或者用户触发第二取消控件193，即M＝0，则用户提交的第一节目集合为空集，第二节目集合为全集，相当于不保存录像文件，处理器删除录制时段已缓存的码流数据，即呈现节目录像全删形态。
在一些实施例中，若M大于0，并且M小于N，则第一节目集合和第二节目集合都为非空真子集，处理器先根据N个节目信息指示的节目播放起止点，将整段录像文件分割为N个节目录制子文件，删除第二节目集合中每个节目信息对应的子文件(为便于区分，本申请将其命名为第二节目录制子文件)，以及按照节目名称，对第一节目集合中每个节目信息对应的子文件(为便于区分，本申请将其命名为第一节目录制子文件)进行命名，将M个第一节目录制子文件存入预设存储器内，即呈现部分节目录像保存、另一部分节目录像删除的形态。
在一些实施例中，参照图34的示例，节目保存页面190显示四个节目信息，即N＝4，分别为节目A、节目B、节目C和节目D，用户点击节目A和节目D对应的选择控件191，然后再触发第二确认控件192，则第一节目集合为{节目A,节目D}，第二节目集合为{节目B,节目C}，则在将录像文件分割为四份，即依次分割出子文件A、子文件B、子文件C和子文件D后，仅将子文件A和子文件D存入预设存储器，子文件A命名为节目A的名称，子文件D命名为节目D的名称，删除子文件B和子文件C。
在一些实施例中，参照图34，节目保存页面190还可设置全选控件194，若用户点击全部的选择控件191，或者用户触发全选控件194，然后再触发第二确认控件192，则M等于N，用户提交的第一节目集合为全集，第二节目集合为空集，则处理器将录制文件分割为N个节目录制子文件并分别命名后，将N个节目录制子文件全部存入预设存储器，而未删除任何子文件，即呈现节目录像全存形态。
在一些实施例中，若以按节目保存模式来保存录像文件，处理器检测到被选定的M个节目录制子文件均已存入预设存储器，则控制显示器在用户界面中提示“录像文件已按节目保存成功”。
在一些实施例中，若以整段保存模式来保存录像文件，处理器检测到整体的录像文件已存入预设存储器，则控制显示器在用户界面中提示“录像文件已保存成功”。用户查看到录像保存成功的提示信息后，可以随时访问预设存储器，观看录像文件。
在一些实施例中，图35为本申请实施例的一种录像文件的保存方法的流程图，所述方法由显示设备的处理器执行，包括如下程序步骤：
步骤S211：响应于停止录制指令，停止执行视频录制任务，生成录像文件。所述视频录制任务用于以按时间录制模式，录制显示设备当前播放的节目视频。
步骤S212：查询在录制时段内显示设备的节目播放信息。
步骤S213：根据所述节目播放信息，确定所述录像文件的目标保存模式。
步骤S214：按照所述目标保存模式，将所述录像文件存入预设存储器内。
在一些实施例中，图36为本申请实施例的另一种录像文件的保存方法的流程图，所述方法由显示设备的处理器执行，包括如下程序步骤：
步骤S221：在当前时间达到启动时间时，启动执行视频录制任务，以按时间录制模式，录制当前播放的节目视频。
步骤S222：响应于停止录制指令，停止执行视频录制任务，生成录像文件。
步骤S223：是否接收到保存指令。若接收到保存指令，则执行步骤S224；若接收到不保存指令，则执行步骤S2212。
步骤S224：查询在录制时段内显示设备的节目播放信息，节目播放信息中包含N个节目信息。
步骤S225：判断N是否大于1。若N大于，执行步骤S226；若N＝1，执行步骤S2211。
步骤S226：询问是否同意采用按节目保存模式。若用户同意采用按节目保存模式，则执行步骤S227；若用户拒绝采用按节目保存模式，执行步骤S2211。
步骤S227：根据N个节目信息指示的节目播放起止点，将所述录像文件分割为N个节目录制子文件，并按照节目名称对所述节目录制子文件进行命名。
步骤S228：显示节目保存页面，所述节目保存页面中显示所述N个节目信息。
步骤S229：接收对所述节目保存页面中M个目标节目信息的选定操作。M小于或等于N。
步骤S2210：将M个目标节目信息对应的第一节目录制子文件存入预设存储器内，删除未被选定的N-M个节目信息对应的第二节目录制子文件。
步骤S2211：不分割所述录像文件，按当前频道名称对所述录像文件进行命名，将所述录像文件存入预设存储器内。
步骤S2212：删除所述录像文件。
在其他可能的实现方式中，如图37示例的录制任务设置页面，用户选择按时间录制模式，设定启动时间T0和停止时间TS后，处理器从EPG中查询当前频道在[T0,TS]时段内的节目播放信息，若该时段内连播多个节目，则显示第一开关控件231，第一开关控件231用于控制“自动按节目保存”功能的开启和关闭。所述“自动按节目保存”功能包含两个能力，一种是在停止录制时无需询问是否保存录像文件，而是自动保存录像文件，另一种是无需用户选择保存模式，而是自行启动按节目保存模式。
在一些实施例中，若用户将第一开关控件231切换为开启状态，则如图38所示，在录制任务设置页面中显示[T0,TS]时段内当前频道包含的节目信息，用户从中选定感兴趣的、期望录制的节目，可选择全部节目保存或部分节目保存。例如图38中录制任务设置页面展示的节目信息分别为节目1、节目2和节目3，用户选定节目1和节目3，之后触发第三确认控件234，则处理器根据启动时间T0、停止时间TS、节目1和节目3的节目信息，创建视频录制任务，所述节目信息包括节目名称和节目播放起止点，设节目1的播放起点为T1_1和播放止点为T1_2，节目3的播放起点为T3_1和播放止点为T3_2。在一些实施例中，处理器检测到系统时间达到启动时间T0，启动执行视频录制任务，按时序连续录制节目1、节目2和节目3，直至检测到系统时间达到停止时间TS，停止执行视频录制任务， 根据T0和T1_2分割出节目1的子文件1，根据T3_1和TS分割出节目3的子文件3，然后分别对子文件1和子文件3进行命名及保存，将被分离出的节目2的子文件2删除。
在一些实施例中，若用户选定节目1和节目3，处理器检测到系统时间达到启动时间T0，启动执行视频录制任务，开启录制节目1，直至检测到系统时间达到T1_2，节目1录制截止，可以立即暂停视频录制任务，即处理器暂停缓存视频码流，此时显示设备处于“只播不录”状态，处理器先对节目1的缓存数据进行格式转换，生成子文件1，对子文件1进行命名并自动保存至预设存储器。处理器检测到系统时间达到T3_1，立即解除任务的暂停状态，恢复对节目3的录制，直至录制停止时，生成子文件3，对子文件3进行命名并自动保存至预设存储器。该实施例通过暂停录制进程，跳过对未被选定的节目2的录制环节，实现录像文件的动态自适应分割以及不感兴趣节目的自动滤除。
在一些实施例中，参照图38，若用户选定节目2和节目3，为跳过用户不感兴趣的节目1的录制环节，可将视频录制任务的启动时间T0后移至节目2的播放起点T2_1，停止时间TS保持为用户设定的时间不变，从而在[T0,TS]这一录制时间内，仅录制节目2和节目3。
在一些实施例中，参照图38，若用户选定节目1和节目2，为跳过用户不感兴趣的节目3的录制环节，可将视频录制任务的停止时间TS前移至节目2的播放止点T2_2，启动时间T0保持为用户设定的时间不变，从而在[T0,TS]这一录制时间内，仅录制节目1和节目2。
在一些实施例中，参照图38，若用户仅选定节目2，为跳过用户不感兴趣的节目1和节目3的录制环节，可将视频录制任务的启动时间T0后移至节目2的播放起点T2_1，将视频录制任务的停止时间TS前移至节目2的播放止点T2_2，即自动调整启动时间T0和停止时间TS以适应用户的节目偏好，从而在[T0,TS]这一录制时间内仅录制节目2，相当于从按时间录制模式调整为按节目录制模式。
在一些实施例中，用户若对节目1、节目2和节目3都不感兴趣，则可重新设定启动时间T0和停止时间TS，或者触发第三取消控件235，取消创建视频录制任务。
在一些实施例中，若用户将第一开关控件231切换为关闭状态，录制任务设置页面取消显示[T0,TS]时段内当前频道包含的节目信息，之后用户触发第三确认控件234，则后续在停止录制时，处理器控制显示器显示图28、图31或图32示例的保存模式询问弹窗，并响应于用户输入的是否保存以及保存模式的相关操作指令，控制录像文件的保存。
在一些实施例中，如图39所示，若用户将第一开关控件231切换为关闭状态，录制任务设置页面取消显示[T0,TS]时段内当前频道包含的节目信息，并显示第二开关控件232，第二开关控件232用于控制“自动整段保存”功能的开启和关闭。若用户将第二开关控件232切换为关闭状态，则在停止录制时，处理器控制显示器显示图28、图31或图32示例的保存模式询问弹窗，并响应于用户输入的是否保存以及保存模式的相关操作指令，控制录像文件的保存；若用户将第二开关控件232切换为开启状态，则在停止录制时，处理器自动以整段保存模式，将录像文件存入预设存储器，无需控制显示器显示保存模式询问弹窗。
在一些实施例中，处理器从EPG中查询当前频道在[T0,TS]时段内的节目播放信息，若查询到该时段内仅播放一个节目，如图40所示，录制任务设置页面不显示任何节目信息，显示第三开关控件233，第三开关控件233用于控制自动保存录像文件功能的开启和 关闭。若用户将第三开关控件233切换为关闭状态，则在停止录制时，处理器控制显示器显示图24示例的第一询问弹窗227，询问用户是否保存录像文件；若用户将第三开关控件233切换为开启状态，则停止录制时，无需弹窗询问是否保存录像文件，而是自动将录像文件存入预设存储器内。通过在录制任务设置页面提供与保存功能相关的开关控件，可以实现停止录制时自动以目标保存模式，将录像文件保存至预设存储器，简化UI及用户操作。
在一些实施例中，本申请中还提供一种具有读写能力的、本地的存储器，该存储器内置于显示设备，并与处理器连接，所述存储器用于受控于处理器，基于前述保存机制，保存录像文件，以及支持处理器从存储器中读取并播放录像文件。
在一些实施例中，本申请中还提供一种具有读写能力、可移动的存储器，该存储器可通过外部接口(例如USB)接入显示设备，所述存储器用于连接显示设备后，受控于处理器，基于前述保存机制，保存录像文件，以及支持处理器从存储器中读取并播放录像文件。
在一些实施例中，用户可在与录像功能相关的设置页面或录制任务设置页面中，指定用于保存录像文件的存储路径，即设置预设存储器，用户可设置预设存储器为本机内置磁盘，也可设置为外部可移动磁盘(例如U盘、移动硬盘、读卡器等)。若预设存储器为外部可移动磁盘，在视频录制及录像保存期间必须保证外部可移动磁盘与显示设备处于有效连接，处理器若检测到外部可移动磁盘断开，则中断视频录制任务，并提示用户检测磁盘连接。预设存储器可按照存入时间、文件大小、录制时长、文件名等规则，对录像文件进行排序，例如按照存入时间递减的顺序排列各项文件，即越新存入的文件排序越靠前。
在一些实施例中，预设存储器可向处理器实时上报自身的可用内存，在视频录制过程中，处理器若检测到磁盘无可用内存，或预设存储器已录满，则立即停止执行视频录制任务，并向用户提示磁盘已录满；处理器检测到系统时间达到启动时间T0时，若查询到预设存储器无可用内存，即预设存储器已无法继续保存录像文件，则不启动执行视频录制任务，并向用户提示磁盘无可用内存、录制失败的信息，用户在清理磁盘内存，或者切换录像文件的存储路径后，可重新创建视频录制任务。此外，处理器还根据预设存储器上报的可用内存，结合TV码流的分辨率等参数，计算并更新如图23示例的视频录制界面中显示的磁盘可录制时间223。
在一些实施例中，用户可能创建多个视频录制任务，处理器可维护一个任务队列，每新建一个视频录制任务A，将视频录制任务A(待执行)加入到任务队列中，以及，每执行完成一个视频录制任务B，将视频录制任务B(已执行)从任务队列中移除，以及，若视频录制任务C超时未执行，将视频录制任务C(已过期)从任务队列中移除。
通过以上技术方案，在录制期间，显示设备可能仅播放一个频道节目，即可以整段保存模式保存录像文件；或者，同一个频道连续播放的多个节目被录制，则以按节目保存模式，将整段录像文件分割为多个对应于独立节目的子文件后，再行存储，方便用户快速回看感兴趣的节目录制视频；本申请还支持丢弃用户不感兴趣的节目录制视频，以降低磁盘内存的消耗。同时，本申请能够适应录制期间内的节目播放场景，匹配录像文件的目标保存模式，改进录像功能，使用户享受更加便捷、高效的录像体验。
在一些实施例中，显示设备200中还可以集成有个人视频录像机，如PVR(Personal video recorder，个人视频录像)，用于录制显示设备200中播放的节目，生成对应的个人视频录像文件。由于用户录制的个人视频录像文件通常占用较大的存储空间，而显示设备200 内无法存储个人视频录像文件，因此，显示设备200还可以外接硬盘设备，用于存储用户录制的个人视频录像文件。
相关技术下，用户录制的视频文件通常包含内容相关联的电视节目，用户点击播放其中一个电视节目后会退出播放，用户想要回看其他相关联的电视节目时，需要手动查看并点击播放其他相关联的电视节目，效率较低。
为了提高对用户感兴趣的视频播放的效率，本申请实施例的处理器250，还被配置为：接收针对第一个人视频录像文件的播放指令，响应于播放指令，播放第一个人视频录像文件，并获取第一个人视频录像文件对应的节目录制信息。
其中，第一个人视频录像文件可以是用户录制的任意一个个人视频录像文件，可以存储在显示设备200外接的硬盘设备中。用户可以通过控制装置100向显示设备200发送各种控制指令，以对显示设备200进行控制。例如，用户要播放第一个人视频录像文件，可以向显示设备200发送针对第一个人视频录像文件的播放指令，处理器250可以接收该播放指令。本申请实施例中，可以预先建立数据库，数据库包括多个个人视频录像文件和多个个人视频录像文件分别对应的节目录制信息。也就是，用户每录制一个个人视频录像文件，即可将该个人视频录像文件和该个人视频录像文件对应的节目录制信息存储在数据库中。可见，数据库中存储的数据可以是不断更新的。
其中，节目录制信息是与用户录制的节目相关的信息，可以包括节目信息(例如节目名称、节目章节等)和录制时刻等。针对电视节目，还可以包括电视频道信息；针对网络节目，还可以包括网络地址信息或应用程序信息等。
由于硬盘设备中的存储空间也是有限的，因此，为了避免剩余存储空间过小而无法存储新的个人视频录像文件和对应的节目录制信息，可以周期性自动清理硬盘设备中用户长时间没有访问的、且时间较早的个人视频录像文件。或者，也可以根据用户自身的需求，手动删除用户不需要的个人视频录像文件。
需要说明的是，用户录制的节目通常具有一定的连续性，例如，用户录制了一个节目的第一节，之后又录制了该节目的第二节。或者，用户录制了同一节目中个人喜欢的不同时间段，例如，用户录制了一个节目第一节的0-30分钟，之后又录制了该节目第一节的45-60分钟。因此，用户录制的个人视频录像文件通常具有一定的相关性，例如，不同个人视频录像文件可能对应相同的节目名称、不同的节目章节，或者对应相同的节目名称、相同的节目章节，但对应不同的录制时刻等。
因此，在获取第一个人视频录像文件对应的节目录制信息后，处理器250，还被配置为：根据该节目录制信息，从数据库中获取与该节目录制信息相关的第二个人视频录像文件。例如，通过数据库中其他个人视频录像文件对应的节目录制信息，对该节目录制信息进行匹配，得到第二个人视频录像文件。
处理器250，还被配置为：基于第一个人视频录像文件的播放状态，显示播放提示信息。
在一些实施例中，当第一个人视频录像文件播放完成时，显示播放提示信息。或者，在第一个人视频录像文件播放完成前预设时间段，显示播放提示信息，即提前显示播放提示信息。例如，第一个人视频录像文件播放完成前1分钟、30秒等，显示播放提示信息。其中，播放提示信息用于提示是否继续播放第二个人视频录像文件。
参见图41，图41为本申请实施例中显示播放提示信息的一种示意图。可见，在节目 播放界面，可以弹出一个新的界面，播放提示信息具体为“是否继续播放相关节目”，并包含“是”、“否”两个按钮。当用户通过控制装置100点击“是”按钮，则发出继续播放指令，表示用户同意继续播放，当用户通过控制装置100点击“否”按钮，则发出退出指令，表示用户不同意继续播放，则退出播放。
处理器250，还被配置为：接收继续播放指令或退出指令；响应于继续播放指令，播放第二个人视频录像文件；或响应于退出指令，退出播放。
本申请实施例的显示设备，通过预先建立数据库，将录制的个人视频录像文件和对应的节目录制信息存储在数据库中，这样，当用户播放第一个人视频录像文件时，可以获取第一个人视频录像文件的节目录制信息，并根据节目录制信息从数据库中获取与该节目录制信息相关的第二个人视频录像文件。基于第一个人视频录像文件的播放状态(例如播放完成时，或者将要播放完成时)，可以显示播放提示信息，播放提示信息用于提示是否继续播放第二个人视频录像文件。如果接收到继续播放指令，则继续播放第二个人视频录像文件；否则，退出播放。针对用户录制的个人视频录像文件，当一个节目播放完成之后可以自动为用户检测相关联的节目，提示用户是否播放相关联的节目，若用户同意则自动播放。这样，可以避免用户主动搜索并播放用户感兴趣的节目，提高对用户感兴趣的节目进行播放的效率。
用户将硬盘设备插入显示设备200后，处理器250，被配置为：当检测到硬盘设备时，若硬盘设备挂载正常，表示该硬盘设备可以使用；可以进一步检测硬盘设备的传输速率；如果硬盘设备的传输速率大于预设传输速率(例如60M/s等)，表示硬盘设备的传输速率满足数据传输的要求，可以向硬盘设备中读写数据，那么在硬盘设备中创建数据库。例如，可以在data分区创建数据库program.db，路径如下：/data/databases/program.db。如果硬盘设备的传输速率小于或等于预设传输速率，可以提示用户更换硬盘设备。
在一些实施例中，数据库的更新过程具体可以为：
当用户观看目标节目(例如可以是用户感兴趣的节目)时，可以通过控制装置100向显示设备200发送针对目标节目的录制指令，处理器250，被配置为：接收针对目标节目的录制指令，响应于录制指令，可以生成目标节目对应的个人视频录像文件以及节目录制信息。其中，录制指令可以包括起始指令和终止指令，起始指令用于开始录制目标节目，终止指令用于结束录制目标节目。在录制结束后，可以生成目标节目对应的个人视频录像文件以及节目录制信息。建立目标节目对应的个人视频录像文件和目标节目对应的节目录制信息的映射关系，将目标节目对应的个人视频录像文件、目标节目对应的节目录制信息和映射关系更新至数据库中。
其中，节目录制信息可以包括路径信息、节目名称、节目章节、录制时刻等。假设路径信息为file:///mnt/media_rw/42AA-8E24/pvr，节目名称为Friends，节目章节为chapter1，录制时刻为04251622，节目录制信息可以表示如下：
file:///mnt/media_rw/42AA-8E24/pvr/Friends_chapter1_04251622.pvr。
在一些实施例中，用户录制的个人视频录像文件为电视频道中播放的电视节目，此时，节目录制信息可以包括电视频道信息和节目信息，还可以包括上述的路径信息、节目章节和录制时刻等。
相应地，节目录制信息可以表示如下：
file:///mnt/media_rw/42AA-8E24/pvr/TV8/Friends_chapter1_04251622.pvr。可以看出，与 上述节目录制信息相比，增加了电视频道信息。
处理器250，被配置为：从预先建立的数据库中获取与节目信息相关的第二个人视频录像文件，其中，第二个人视频录像文件可以与电视频道信息不相关。也就是说，在获取第二个人视频录像文件时，可以针对节目信息，而不针对频道信息进行区分，这样，可以实现跨频道搜索，即为用户搜索到更多感兴趣的个人视频录像文件。除此之外，也可以同时针对节目信息和频道信息进行区分，为用户搜索同一频道用户感兴趣的个人视频录像文件。之后，根据用户的播放需求播放搜索到的个人视频录像文件，或退出播放。
在一些实施例中，节目信息的数量可以为多个，且按顺序排列。例如，如果节目信息包括节目名称和节目章节，排序结果可以为节目名称、节目章节，排序越靠前，表示该节目信息对应的范围越大，排序越靠后，表示该节目信息对应的范围越小。
处理器250，被配置为：按照多个节目信息的顺序，依次根据单个节目信息，从预先建立的数据库中进行逐层筛选，得到与至少一个节目信息相关的个人视频录像文件，并将得到的个人视频录像文件确定为第二个人视频录像文件。
参见图42，图42为本申请实施例中获取第二个人视频录像文件的一种流程图，在此假设第一个人视频录像文件的节目录制信息中包括两个节目信息，可以包括以下步骤：
步骤S702：播放第一个人视频录像文件，并获取第一个人视频录像文件的节目录制信息。
步骤S704：获取该节目录制信息中的第一个节目信息，并从数据库中获取除第一个人视频录像文件之外的其他个人视频录像文件的节目录制信息。
步骤S706：判断获取到的单个个人视频录像文件的节目录制信息中是否包含第一个节目信息。如果包含第一个节目信息，表示匹配到与第一个节目信息相关的个人视频录像文件，可以执行步骤S708；如果不包含第一个节目信息，表示未匹配到与第一个节目信息相关的个人视频录像文件，由于第一个节目信息对应最大的范围，在未匹配到与第一个节目信息相关的个人视频录像文件的情况下，可以执行步骤S710。
步骤S708：将该单个个人视频录像文件作为候选个人视频录像文件。
步骤S710：不存在与第一个人视频录像文件的节目信息相关的第二个人视频录像文件。
步骤S712：判断候选个人视频录像文件的节目录制信息中是否包含第二个节目信息。如果包含第二个节目信息，执行步骤S714；如果不包含第二个节目信息，也可以执行步骤S714。
步骤S714：将该候选个人视频录像文件确定为第二个人视频录像文件。
在上述步骤S714中确定的第二个人视频录像文件可以同时与第一个节目信息和第二个节目信息匹配，此时第二个人视频录像文件与第一个人视频录像文件相关程度较高。或者，第二个人视频录像文件与第一个节目信息匹配，与第二个节目信息不匹配，此时第二个人视频录像文件与第一个人视频录像文件相关程度较低。
可以理解的是，在第一个人视频录像文件的节目录制信息中包含三个或更多个节目信息的情况下，可以按照类似的方式进行逐层筛选。当数据库中的单个个人视频录像文件与第一个人视频录像文件的节目录制信息中的节目信息匹配的数量越多，表示该单个个人视频录像文件与第一个人视频录像文件的相关程度越高。
举例而言，如果第一个人视频录像文件的节目录制信息中的第一个节目信息为Friends，第二个节目信息为chapter，在执行步骤S708之后，得到4个候选个人视频录像文件的节 目录制信息如下：
file:///mnt/media_rw/42AA-8E24/pvr/TV8/Friends_chapter1_04251622.pvr；
file:///mnt/media_rw/42AA-8E24/pvr/TV8/Friends_chapter1_04251222.pvr；
file:///mnt/media_rw/42AA-8E24/pvr/TV6/Friends_chapter3.pvr；
file:///mnt/media_rw/42AA-8E24/pvr/TV2/Friends_chapter16.pvr。
可以看出，上述每个节目录制信息中均包括节目信息Friends。进一步地，执行步骤S712，如果包含chapter，将候选个人视频录像文件确定为第二个人视频录像文件。由于上述每个节目录制信息中均包括节目信息chapter，因此，最终确定4个候选个人视频录像文件均为第二个人视频录像文件。
在一些实施例中，第二个人视频录像文件的数量为多个，处理器250，被配置为：根据第二个人视频录像文件的节目信息和第一个人视频录像文件的节目信息，确定第二个人视频录像文件和第一个人视频录像文件的相关程度；按照相关程度从高至低的顺序，对多个第二个人视频录像文件进行排序，得到排序结果。如果两个或更多个第二个人视频录像文件对应的相关程度相同，可以对两个或更多个第二个人视频录像文件任意排序。
例如，在图43步骤S712之后，如果包含第二个节目信息，执行步骤S714；如果不包含第二个节目信息，也执行步骤S714。那么，包含第二个节目信息时执行步骤S714所确定的第二个人视频录像文件，与不包含第二个节目信息时执行步骤S714所确定的第二个人视频录像文件相比，相关程度较高。
在一些实施例中，如果节目信息中包括序号信息，也可以在考虑第二个人视频录像文件对应的相关程度的同时，考虑第二个人视频录像文件的节目信息的序号信息，对第二个人视频录像文件进行排序。
例如，如果上述4个候选个人视频录像文件均为第二个人视频录像文件，4个第二个人视频录像文件对应的相关程度相同，此时可以结合节目信息中的序号信息，对4个第二个人视频录像文件进行排序。由于Friends不存在序号信息，chapter存在序号信息，因此，可以根据chapter对4个第二个人视频录像文件进行排序。chapter的序号信息越小，对应的第二个人视频录像文件可以越靠前。针对chapter的序号信息相同的第二个人视频录像文件，还可以进一步结合录制时刻对第二个人视频录像文件进行排序，录制时刻越早，对应的第二个人视频录像文件可以越靠前。
处理器250，被配置为：当显示播放提示信息时，可以按照排序结果显示多个第二个人视频录像文件的节目录制信息。可选的，可以显示多个第二个人视频录像文件的节目录制信息中的节目信息。
参见图43，图43为本申请实施例中显示播放提示信息的又一种示意图。可以看出，当显示播放提示信息时，显示了3个第二个人视频录像文件的节目信息。用户根据节目信息，可以根据自己的喜好确定是否继续播放对应的第二个人视频录像文件。当用户通过控制装置100点击按钮“是”时，向显示设备200发送继续播放指令。
处理器250，被配置为：响应于继续播放指令，按照排序结果，依次播放多个第二个人视频录像文件。也就是，在继续播放多个第二个人视频录像文件时，用户可以不选择下一个继续播放的第二个人视频录像文件，此时直接按照排序结果进行播放。
在一些实施例中，处理器250，被配置为：接收针对多个第二个人视频录像文件中单个第二个人视频录像文件的继续播放指令，即用户也可以通过控制装置100向显示设备200 发送针对某一个第二个人视频录像文件的继续播放指令。处理器250可以响应于继续播放指令，播放单个第二个人视频录像文件。
例如，如果用户想要播放图44中的节目2，可以先通过控制装置100选取节目2，然后通过控制装置100发送继续播放指令。这样，在播放完成第一个人视频录像文件后，可以继续播放节目2对应的第二个人视频录像文件。
本申请实施例的显示设备，在录制生成个人视频录像文件，可以同时生成个人视频录像文件对应的节目录制信息，并将个人视频录像文件、个人视频录像文件对应的节目录制信息和两者之间的映射关系存储在数据库中。在用户播放第一个人视频录像文件时，可以自动根据第一个人视频录像文件时的节目录制信息为用户匹配相关的第二个人视频录像文件，并基于第一个人视频录像文件的播放状态(例如播放完成时，或者将要播放完成时)，可以显示播放提示信息，以提示用户是否播放第二个人视频录像文件。如果接收到继续播放指令，则继续播放第二个人视频录像文件；否则，退出播放。其中，第二个人视频录像文件可以与电视频道信息不相关，以实现跨频道的录制节目搜索和自动连续播放，从而提高对用户感兴趣的视频播放的效率，进而提升用户体验。
参见图44，图44为本申请实施例中视频处理方法的一种流程图，可以包括以下步骤：
步骤S902：接收针对第一个人视频录像文件的播放指令，响应于播放指令，播放第一个人视频录像文件，并获取第一个人视频录像文件的节目录制信息。
步骤S904：根据节目录制信息，从预先建立的数据库中获取与节目录制信息相关的第二个人视频录像文件；数据库包括多个个人视频录像文件和多个个人视频录像文件分别对应的节目录制信息。
步骤S906：基于第一个人视频录像文件的播放状态，显示播放提示信息，播放提示信息用于提示是否继续播放第二个人视频录像文件。
步骤S908：接收继续播放指令或退出指令；响应于继续播放指令，继续播放第二个人视频录像文件；或者，响应于退出指令，退出播放。
其中，节目录制信息包括电视频道信息和节目信息；那么，在执行步骤S904时，具体包括：从预先建立的数据库中获取与节目信息相关的第二个人视频录像文件，第二个人视频录像文件与电视频道信息不相关。
在一些实施例中，节目信息的数量为多个，且按顺序排列；那么，在执行步骤S904时，具体包括：按照多个节目信息的顺序，依次根据单个节目信息，从预先建立的数据库中进行逐层筛选，得到与至少一个节目信息相关的个人视频录像文件，并将得到的个人视频录像文件确定为第二个人视频录像文件。
在一些实施例中，如果通过执行步骤S904得到的第二个人视频录像文件的数量为多个；那么，上述视频处理方法还包括：根据第二个人视频录像文件的节目信息和第一个人视频录像文件的节目信息，确定第二个人视频录像文件和第一个人视频录像文件的相关程度；按照相关程度从高至低的顺序，对多个第二个人视频录像文件进行排序，得到排序结果；当显示播放提示信息时，按照排序结果显示多个第二个人视频录像文件的节目录制信息。
然后，在执行步骤S908中的响应于接收到继续播放指令，继续播放第二个人视频录像文件时，具体包括：响应于继续播放指令，按照排序结果，依次播放多个第二个人视频录像文件。
在一些实施例中，在执行步骤S908中的响应于接收到继续播放指令，继续播放第二个人视频录像文件时，具体包括：接收针对多个第二个人视频录像文件中单个第二个人视频录像文件的继续播放指令；响应于继续播放指令，播放单个第二个人视频录像文件。
在一些实施例中，用户将硬盘设备插入显示设备后，上述视频处理方法还包括：当检测到硬盘设备时，若硬盘设备挂载正常，检测硬盘设备的传输速率；如果硬盘设备的传输速率大于预设传输速率，在硬盘设备中创建数据库。
参见图45，图45为本申请实施例中更新数据库的一种流程图，可以包括以下步骤：
步骤S1002：接收针对目标节目的录制指令，响应于录制指令，生成目标节目对应的个人视频录像文件以及节目录制信息。
步骤S1004：建立目标节目对应的个人视频录像文件和目标节目对应的节目录制信息的映射关系。
步骤S1006：将目标节目对应的个人视频录像文件、目标节目对应的节目录制信息和映射关系更新至数据库中。
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。
