图2B为本申请实施例示例性示出的一种EPG界面。如图2B所示，在垂直方向上，各频道以多行形式自上至下顺序排列；水平方向是时间轴方向，每个频道的广播节目按照节目播放时间顺序排列显示为一行，每行内各个广播节目以节目播放时间顺序排列，且各个广播节目的显示区域的大小表示其广播时间长度，广播节目的显示区域的起始位置表示该广播节目的起始播放时刻，显示区域的结束位置表示该广播节目的终止播放时刻，显示区域内显示其节目名 称。例如在图2B所示的EPG用户界面中，示出了五个频道(DC a-DC e)在3:00PM到5:00PM之间的广播节目菜单，具体包括DC a频道的广播节目a0-a3，DC b频道的广播节目b0-b5，DC c频道的广播节目c0-c6，DC d频道的广播节目d0-d8，DC e频道的广播节目e0-e7。
当选择器(显示焦点所在位置的界面元素)落入某一广播节目的显示区域时，EPG用户界面上同时示出该广播节目的向导(Guide)。广播节目的向导可以包括广播节目的频道标识、播放时间(起始播放时刻和终止播放时刻)、节目类型和内容简介等。如图2B所示，当选择器落在广播节目a2的显示区域时，在位于EPG用户界面上侧的向导区域内显示广播节目a2所属频道的频道标识DCa，广播节目a2的播放时间4:19PM-5:19PM、广播节目a2的节目类型movie以及广播节目a2的内容简介。
在图2B所示的EPG界面中，通过界面元素来标识不同的节目类型，这里的界面元素可以是用户自定义的颜色标识。在一些实施例中，用户自定义设置需要显示颜色标识的节目类型和用于标记得颜色标识。例如，设置的节目类型分别为movie、shows、news，设置的颜色标识分别为浅灰色标识、深灰色标识和黑色标识，且设置浅灰色标识对应节目类型movie、深灰色标识对应节目类型shows、黑色标识对应节目类型news。当EPG用户界面显示的广播节目包括movie、shows和/或news时，在广播节目显示区域的底侧部分分别填充浅灰色、深灰色和/或黑色。
此外，如图2B所示，在EPG用户界面右上角区域还显示提示信息，该提示信息用于指示不同颜色标识和其对应节目类型，以使用户能够直观区分不同颜色标识对应的广播节目的节目类型。
一些实施例中，EPG用户界面还示出了指示当前时间的界面元素，例如图2B中的指示当前时间3:50的竖线，使得用户能够直观看出在当前时刻各个频道正在播放的广播节目，以及正在播放的广播节目的实时播放进度。
示例的，当用户需要查看其他时间段的节目信息时，可以通过操作控制装置100的方向键以使焦点落入时间轴，当焦点在时间轴上时，可以继续操作左右键以输入用于调整节目时间段的指令，响应于该调整节目时间段的指令，控制器250将读取存储器中与调整后的节目时间段对应的广播EPG信息，并从该广播EPG信息解析出各频道的频道信息和各频道内所有广播节目的节目信息，用以更新EPG界面。
在上述示例中，由于广播EPG信息仅包含未来一段时间的节目信息，因此现有的EPG界面仅能显示未来一段时间的广播节目，而不能显示过去的广播节目。
另外，由于广播EPG信息所包含的节目信息通常较为简略，例如其仅包括节目名称、主演及导演姓名、节目的文字简介，使得用户无法了解到诸如节目的演员详细信息、封面图片及其是否可进行网络播放等信息。
为了解决上述问题，本申请实施例中，通过通信器220从网络服务端获取预定时间段的网络EPG信息，该预定时间段至少包括一定长度的历史时间段(例如过去7天)，还可以包括一定长度的未来时间段(例如未来7天)，进而，获取的网络EPG信息至少包括历史EPG信息，还可以包括未来EPG信息。解码器对获取的网络EPG信息进行解码，控制器将解码得到的网络EPG信息通过内部总线存储在存储器260中，以备显示EPG用户界面。
基于上述获取的网络EPG信息，一方面，当需要显示历史节目信息时，控制器从存储器260中读取网络EPG信息，并从中解析出需要显示的历史EPG信息，EPG生成器则根据控制器解析出的历史EPG信息，生成包含历史节目信息的EPG界面；另一方面，可以将广播EPG信息与网络EPG信息加以融合，进而扩充EPG界面可显示的内容，满足用户的更多需求。
在一些实施例中，网络EPG信息携带有各个广播节目对应的网络资源信息，该网络资源信息包括用于标识广播节目的网络播放地址的字段和用于标识广播节目的网络资源状态的字段。控制器通过解析这些字段，实现对部分广播节目的网络播放，以及在EPG界面上对可进行网络播放的广播节目进行标记。
在一些实施例中，网络EPG信息及其携带的各个广播节目的网络资源信息存储在运营商服务器上，即EPG网络服务端。显示设备开机时，根据EPG网络服务端的要求进行签名认证；签名认证成功后，显示设备根据频道信息(频道标识)和时间段信息向EPG网络服务端请求对应的网络EPG信息。
图2C-2H示例性示出了通过控制装置100操作显示设备，以显示包含历史节目单的EPG界面的交互过程。
为了方便说明，本申请以从网络信号或者广播信号中获取的当前时刻为基准，将各频道在当前时刻和晚于当前时刻(未来一段时间)的广播节目菜单称为未来节目单，将各频道在早于当前时刻(过去一段时间)的广播节目菜单称为历史节目单。未来节目单中显示未来节目的节目信息，历史节目单显示历史节目的节目信息。例如，图2B所示指示当前时间的竖线左侧的节目单位历史节目单，右侧的节目单位未来节目单。
当显示器显示如图2A所示的广播节目画面时，如果用户通过操作控制装置 而输入用于显示电子节目指南EPG的第一输入指令时，控制器可以响应于该第一输入指令，控制在显示器上显示第一EPG界面，该第一EPG界面包括未来节目单，和，用于指示是否可显示历史节目单的界面元素。
在一些实施例中，用于指示是否可显示历史节目单的界面元素可以是：显示在频道标识左侧的指示性标识，该指示性标识用于指示该频道的历史节目信息是否可被显示。
一些实施例中，图2C示出了一种第一EPG界面，该第一EPG界面显示出以频道和节目播放时间顺序进行排序的未来节目单，该未来节目单示出了五个频道(DC a-DCe)在3:00PM到5:00PM之间的广播节目，其中，在频道DCa和DCd的频道标识左侧显示有指示性标识“＜”，用于指示频道DCa和DCd的历史节目信息可被显示和查看，以使用户能够根据该指示获知可以查看哪些频道的历史节目信息。
在显示器显示图2C所示的第一EPG界面时，用户可以通过操作控制装置100输入用于显示目标频道的历史节目信息的第二输入指令，例如，用户通过操作控制装置100的输入，而改变焦点(选择器)位置，当焦点在目标频道上时，用户触发控制装置100上向左的方向键而输入前述第二输入指令。其中，目标频道是历史节目信息可被显示的频道，如图2C中的频道DCa和频道DCd。
在另一些实施例中，用于指示是否可显示历史节目单的界面元素可以是：用于改变节目单所属日期的控件。
一些实施例中，上述用于改变节目单所属日期的控件，具体为可以触发显示历史节目单且与历史节目单所属日期相关联的控件。当历史节目单可被显示时，该控件为可点击的界面元素，用户可以通过操作控制装置而点击该控件以 显示历史节目单或者改变节目单所属的日期，当由于不存在相应的历史EPG信息而不可显示历史节目单时，该控件转换为不可点击的界面元素。
一些实施例中，图2D示出了另一种第一EPG界面，与图2C不同的是，图2D中，在频道标识的显示区域上方示出了两个用于改变节目单所属日期的控件，分别为“前一天”和“后一天”，分别用于以当前显示的节目单所属日期为基准，触发显示前一天和后一天的节目单。
在显示器显示图2D所示的第一EPG界面时，用户可以通过操作控制装置输入用于显示前一天的历史节目信息的第二输入指令，例如，用户通过操作控制装置100的输入而改变焦点(选择器)位置以使焦点落入控件“前一天”上，并触发控制装置100上的确定键以点击该控件，从而输入前述第二输入指令。
具体实现时，当控制器接收到第一输入指令时，响应于该指令，从存储器260中读取广播EPG信息和网络EPG信息，并从中解析出第一EPG界面所需的节目信息。EPG生成器根据控制器解析出的节目信息，绘制第一EPG界面。其中，EPG生成器基于历史EPG信息的存在情况，绘制第一EPG界面中的指示历史节目单是否可被显示的界面元素。以图2D为例，当历史EPG信息中存在前一天的节目信息时，生成包含可点击控件(“前一天”)的第一EPG界面，否则为不可点击控件。
当显示器上显示如图2C或2D所示的第一EPG界面时，如果用户输入用于显示历史节目单的第二输入指令，控制器可以响应于该指令，控制在显示器上显示第二EPG界面，即控制由第一EPG界面跳转到第二EPG界面，该第二EPG界面包括历史节目单，该历史节目单中的历史节目信息从网络EPG信息中解析得到。
一些实施例中，当在图2C所示第一EPG界面上输入用于显示目标频道DCa的历史节目信息的指令后，进入图2E所示的第二EPG界面。如图2E所示，水平方向是时间轴方向，该时间轴具体为以天为时间单位的日期轴，每个日期所在的每行内，与日期对应的广播节目按照节目播放顺序自上至下顺序排列，例如图2E示出了频道DCa在3月28日(星期六)至3月30日(星期一)期间每一天的广播节目，分别为3月28日播放的广播节目a00-a04，3月29日播放的广播节目a10-a14，3月30日播放的广播节目a20-a24。此外，图2E所示第一EPG界面右侧区域的垂直方向上，各频道以多行形式自上至下顺序排列，其显示的频道至少包括前述目标频道。
另一一些实施例中，在图2D所示第一EPG界面上输入用于显示前一天的历史节目信息的指令后，进入图2F所示的第二EPG界面。该第二EPG界面包括历史节目单，如图2F所示，示出了频道DCa、DCb、DCc、DCd、DCe在前一天3:00PM到5:00PM之间的历史节目单。
一些实施例中，当响应于用户对界面控件的点击而触发显示历史节目单或改变历史节目单所属的日期时，节目单中显示的节目时间段可以保持不变。例如结合图2D和图2F所示，图2D中未来节目单与图2F中历史节目单显示的节目时间段均为3:00PM到5:00PM。
一些实施例中，当不存在前一天对应的历史EPG信息而无法显示相应的历史节目信息时，图2F所示EPG界面上的“前一天”控件转变为不可点击的界面元素或者在界面上消失，从而使用户可以直观地分辨出是否可以继续查看前一天的历史节目单。
本申请中，第二EPG界面还可以显示指示当前显示的节目时间段是否可被 调整的指示标识，例如图2E和图2F中时间轴最右端显示的向左箭头“＜”。
当显示设备显示如图2E和图2F所示的第二EPG界面时，用户可以通过操作控制装置输入用于调整节目时间段的第三输入指令，例如，用户通过操作控制装置100的输入而改变焦点(选择器)位置以使焦点落入时间轴上，当焦点在时间轴上时，用户可以触发控制装置上向右的方向键而输入第三输入指令。
当控制器接收到上述第三输入指令时，响应于该指令，将历史节目单当前显示的节目时间段向后调整到下一个时间段或者向前上一个时间段，并根据调整后的节目时间段更新界面中的历史节目单。
图2G为在图2F所示EPG界面中输入用于向后调整节目时间段的指令后进入的界面，与图2F相比，界面中显示的节目时间段由3:00PM-5:00PM向后调整到5:00PM-7:00PM。
图2H为在图2F所示EPG界面中输入用于向前调整节目时间段的指令后进入的界面，与图2F相比，界面中显示的节目时间段由3:00PM-5:00PM向前调整到1:00PM-3:00PM。
本申请中，第二EPG界面还可以显示用于指示频道的未来节目信息是否可被显示/查看的指示标识，例如该指示标识可以为图2E中频道标识右侧的“＜”。
当显示设备显示如2E所示EPG界面时，用户可以通过操作控制装置输入用于显示目标频道的未来节目信息的第四输入指令。例如，用户通过操作控制装置100的输入而改变焦点(选择器)位置以使焦点落入目标频道上，当焦点在目标频道上时，用户触发控制装置100上的向右的方向键而输入前述第四输入指令。其中，目标频道是其未来节目信息可被显示的频道。
当控制器接收到上述第四输入指令时，响应于该第四输入指令，从第二EPG 界面返回到第一EPG界面，以显示目标频道的未来节目信息。例如从图2E所示的第二EPG界面返回至如图2D所示的第一EPG界面。
为了用户能够通过历史节目单和/或未来节目单直观了解到其上的广播节目是否可进行网络播放，进而实现节目的回看或者提前播放，本申请实施例中，第一EPG界面或者第二EPG界面上还可以显示各个广播节目对应的资源状态标识，该资源状态标识可以是指示广播节目可进行网络播放的第一标识、不可进行网络播放的第二标识以及即将可网络播放的第三标识。其中，即将可网络播放是指在某一未来时间点之后即可进行网络播放。
一些实施例中，在图2C及图2D所示的第一EPG界面上，或者在图2E至图2F所示的第二EPG界面上，当焦点落入某一广播节目的显示区域时，EPG界面上同时示出该广播节目的向导，该广播节目的资源状态标识即显示在该向导区域，例如图2F中示出的可网络播放字样。
需要说明的是，图2F仅是一种示例性表示，实际上，资源状态标识是指示性界面元素的一种，其诸如文字、图形、颜色和/或显示位置等表现形式可采用多种不同的形式，本申请不予限定。
具体实现时，当控制器接收到第一输入指令或者第二输入指令时，开始读取存储器中的网络EPG信息，进而读取到网络EPG信息携带的网络资源信息，然后通过解析每个广播节目所对应的网络资源信息的字段，确定对应的资源状态标识。例如图2F所示的EPG界面，即是控制器通过解析广播节目a2(3月28日4:19PM-5:19PM播放过的历史节目)对应的网络资源状态信息，进而显示的资源状态标识。
根据以上实施例，本申请还提供一种电子节目指南EPG的呈现方法，主要应用于显示设备，如智能电视，本申请所述方法的执行主体为显示设备的控制器，但不仅限于此。后续实施例中均以显示设备为例进行说明。
图3为本申请示例性示出的一种电子节目指南EPG的呈现方法流程图。如图3所示，该方法可以包括：
步骤301，在显示器上显示节目画面；
步骤302，接收用户输入的用于显示电子节目指南EPG的第一输入指令；
步骤303，响应于该第一输入指令，呈现第一EPG界面，该第一EPG界面包括以频道和节目播放时间顺序进行排序的未来节目单，和，用于指示历史节目信息是否可显示的界面元素；
步骤304，接收在第一EPG界面输入的用于显示历史节目信息的第二输入指令；
步骤305，响应于该第二输入指令，从第一EPG界面跳转到第二EPG界面，该第二EPG界面包括历史节目单，该历史节目单中的历史节目信息从网络服务端获取得到。
本申请方法基于从网络服务端获取的历史EPG信息构建第二EPG界面并呈现，满足用户查看历史节目单的需求。
在一些实施例中，根据从广播信号中提取的广播EPG信息和从网络服务端获取的网络EPG信息，生成第一EPG界面并呈现。具体实现时，首先分别确定未来节目单待显示的频道信息和待显示的节目时间段；然后根据确定的频道信息和节目时间段，从存储器中读取对应的广播EPG信息和网络EPG信息；再从广播EPG信息和网络EPG信息中分别解析出需要显示的节目信息，例如， 节目名称、节目类型、演员信息、导演及编剧信息、节目简介、封面图片、资源状态标识、节目的音视频属性等等；最后根据从广播EPG信息和网络EPG信息中分别解析出的节目信息，生成第一EPG界面。
为方便区分及说明，将从广播EPG信息中解析出的节目信息称为广播节目信息，将从网络EPG信息中解析出的节目信息称为网络节目信息。
为了实现对未来节目单中节目信息的扩充，本实现方式按照预定的节目信息属性，将广播节目信息与网络节目信息相融合，得到综合节目信息，用以生成生成第一EPG界面。其中，预定的节目信息属性包括节目名称、节目副标题(secondaryTitle)、节目类型、演员信息、导演及编剧信息、节目简介、封面图片(一般为用于下载封面图片的地址，contentImage)、资源状态标识(available属性)、节目ID(program_id)、节目的网络播放地址(mediaURL)节目的音视频属性(如adFlag、hdFlag、signFlag)等属性中的一种或者多种。
示例的，将广播EPG信息中节目名称和网络EPG信息中的节目名称进行整合，得到用于显示的节目名称；将广播EPG信息中的封面图片(可能无封面图片)和网络EPG信息中的封面图片进行整合，得到用于显示的封面图片；根据网络EPG信息中的网络资源信息确定用于显示的资源状态标识，等等。
例如，将广播EPG信息和网络EPG信息中同一个广播节目对应的如下标识字段进行融合，即令：
dest[j].secondaryTitle＝src[i].secondaryTitle；
dest[j].contentImage＝src[i].contentImage；
dest[j].available＝src[i].available；
dest[j].program_id＝src[i].program_id；
dest[j].mediaURL＝src[i].mediaURL；
dest[j].adFlag＝parseInt(src[i].program_ad)；
dest[j].hdFlag＝parseInt(src[i].hd_or_sd)；
dest[j].signFlag＝parseInt(src[i].signFlag)；
……
在步骤305中，根据从网络服务端获取的网络EPG信息，即网络EPG信息中的历史EPG信息，生成第二EPG界面并呈现。具体实现时，首先分别确定历史节目单待显示的频道信息和待显示的节目时间段；然后根据确定的频道信息和节目时间段，从存储器中读取对应的网络EPG信息；再从读取出的网络EPG信息中解析出需要显示的历史节目信息；最后根据解析出的历史节目信息生成第二EPG界面。
以下以第一EPG界面的呈现场景为例，对控制器确定待显示的频道信息以及确定待显示的节目时间段的实现方式作出详细说明。
作为可能的实现方式，根据当前正在播放频道确定未来节目单待显示的频道信息；根据当前时间确定未来节目单待显示的节目时间段。
示例的，根据式(1)至式(3)确定上述待显示的频道信息。
Figure PCTCN2020092091-appb-000001
startIndex＝(currentPage-1)×pageSize  式(2)
endIndex＝(currentPage×pageSize-1   式(3)
其中，频道编号用于表征频道在频道列表中的排列位序，一个频道对应一个频道编号，index表示当前正在播放频道的频道编号；当对频道列表进行分页显示时，各页面上显示的频道组成频道列表，页码用于表征页面在所有页面中 的排列位序，currentPage表示待显示页面的页码，pageSize表示每页显示的频道数量，startIndex表示待显示页面中第一个频道的频道编号，endIndex表示待显示页面中最后一个频道的频道编号。而待显示的频道信息即为通过待显示页面中第一个至最后一个频道的频道编号表征的信息，进而，根据每个频道的频道标号可以获得每个频道的频道标识。
另一示例的，首先获取当前时间，然后根据当前时间和界面上时间轴的显示长度确定时间轴显示的起始时间和结束时间，进而获得未来节目单待显示的节目时间段。例如，获取到当前时间为2020-01-02 15:25:20，通过时间取整确定时间轴显示的起始时间为2020-01-02 15:00:00，根据该起始时间和时间轴的显示长度2h，确定时间轴显示的结束时间为2020-01-02 17:00:00。
示例的，根据解析到的广播节目的起始播放时刻和终止播放时刻，确定广播节目的播放时长，根据广播节目的播放时长与时间轴的显示长度的比例，确定广播节目的显示区域的长度，以使显示区域的大小表示广播节目的广播时间长度；根据各个频道内各广播节目的播放时间顺序，绘制各广播节目的显示区域；以及根据各广播节目的节目名称，在相应的显示区域上绘制对应的节目名称。
在一些实施例中，网络EPG信息(包括历史EPG信息和未来EPG信息)携带有各个广播节目对应的网络资源信息，该网络资源信息包括广播节目的网络播放地址和/或资源状态信息。其中，网络播放地址用于实现相应广播节目的网络播放，资源状态信息用于确定广播节目的资源状态标识，用以显示在EPG界面上，进而提示用户。
在这些实施例中，当焦点在历史节目单或者未来节目单上的目标节目时， 接收用于播放目标节目的指令；响应于用于播放目标节目的指令，根据目标节目对应的网络资源信息中的网络播放地址，获取目标节目对应的视频文件；播放目标节目对应的视频文件。
具体实现中，本申请还提供一种计算机存储介质，其中，该计算机存储介质可存储有程序，该程序执行时可包括本申请提供的开机动画播放方法的各实施例中的部分或全部步骤，当本申请提供的显示设备的控制器运行所述计算机程序指令时，所述控制器执行本申请所述的控制器被配置的步骤。所述的存储介质可为磁碟、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。
出于说明和描述的目的，提供了前述实施例，而非旨在穷举或限制本申请。具体实施例的各个元件或特征通常不限于该具体实施例，而是在适用情况下即使未具体示出或描述也可在所选实施例中使用或互换。同样也可以进行许多形式变型，这种变型不被认为是脱离本申请所附的权利要求的范围，而且所有这样的修改被涵盖在本申请所附的权利要求的范围内。
