Description

电视频道搜索控制方法、装置
本申请要求于2016年3月29日提交中国专利局、申请号为201610187032.6、发明名称为“电视频道搜索控制方法、装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及数字电视技术领域，特别是涉及电视频道搜索控制方法、装置。
背景技术
数字电视技术中将模拟信号形式的视频信息压缩为数字信号，以传输流(Transport Stream，TS)方式进行远距离传输，故相对于传统的模拟电视，数字电视不仅抗干扰能力强，可以提供图像更清晰、音质更高的电视节目，还可以提高频谱利用率，拓宽频道资源。具体的，在模拟电视中，每个物理频道只能传输一套节目信号，但在数字电视中，每个物理频道能传输多套节目；因此，数字电视中，为区分同一物理频道中传输的不同节目，每套节目还配置有一个虚拟频道号，即直接展示给用户、用于换台的频道号。
在数字电视中常用的频道搜索方式包括自动搜台和手动搜台等。相对于自动搜台逐个针对每个物理频道进行搜索，手动搜台针对一个目标频道的搜索更精细，且耗时更短。实现用户手动搜台时，需要用户输入要搜索的物理频道，由频道管理器接收用户输入的物理频道，然后在该物理频道中进行搜索，并将搜索结果通过用户界面展示给用户。
然而，发明人在实现本发明的过程中发现：实际应用中，用户通常只记得虚拟频道号，难以确定要搜索的节目所在的物理频道，且某套节目对应的虚拟频道号可能会发生变化，导致用户难以通过手动搜台得到自己想看的节目；而若采用自动搜台方式，则会因搜索范围增大而需要较长的搜索时间，且可能会由于搜索不够精细而搜不到用户想看的节目。
发明内容

附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，对于本领域普通技术人员而言，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

图2为本申请一个实施例提供的数字电视相关的主要硬件架构图；
图3为本申请实施例提供的数字电视的一种用户界面示意图；
图4为本申请实施例提供的数字电视的另一种用户界面示意图；
图5为本申请另一个实施例提供的电视频道搜索控制方法的流程图；
图6为本申请一个实施例提供的电视频道搜索控制装置的结构框图。
具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
首先对本申请提供的电视频道搜索控制方法的实施例进行说明。图1为本申请一个实施例提供的电视频道搜索控制方法流程图；参照图1，该方法包括如下步骤。
S11、在接收到用户的手动搜台指令后，在用户界面中显示频道对应表。
参照图2所示的数字电视频道搜索控制相关硬件架构图，用户可以通过遥控器201发送手动搜台指令，遥控器201将该指令通过红外等无线信号形式发送至数字电视主机，数字电视主机的用户接口202接受来自遥控器201的手动搜台指令后，将该手动搜台指令发送至数字电视的频道管理器203，从而触发频道管理器203在显示器204中显示的用户界面中加载所述频道对应表。
其中，所述频道对应表至少记录有物理频道与虚拟频道号之间的对应关系， 如下表1所示；所述频道信息包括物理频道和虚拟频道号中的至少一种。
表1频道对应表
虚拟频道号 物理频道(MHz)
001 403
002 411
… …
用户在看到所述频道对应表后，即可确定自己要搜索的节目(即目标节目)对应的物理频道或虚拟频道号。
S12、接收用户输入的频道信息，并根据所频道信息在相应的物理频道内进行搜索。
用户在根据所述频道对应表确定目标节目对应的频道信息后，可以通过遥控器201输入相应的频道信息，用户接口202接收用户输入的频道信息，并将其转发至频道管理器203，频道管理器203根据该频道信息进行搜索相应的物理频道中是否存在节目信号。
在一种具体实施方式中，用户输入的频道信息可以为目标节目对应的物理频道，从而频道管理器可以直接执行搜索操作。在另一种具体实施方式中，用户输入的频道信息也可以为目标节目对应的虚拟频道号；相应的，频道管理器在接收到该虚拟频道号后，先根据频道对应表确定相应的物理频道，再在确定的物理频道内进行搜索。
S13、将搜索结果展示在所述用户界面中。
由以上技术方案可知，本申请实施例中，在接收到用户的手动搜台指令后，显示预存的频道对应表，通过该频道对应表提示用户查找并输入自己要搜索的目标节目对应的频道信息，保证在准确的物理频道内进行搜索，从而可以提高手动搜台的搜索效率及成功率，避免出现搜索不到用户想看的目标节目甚至搜索不到任何节目的现象，提高用户体验好感度。
在本申请一个可行的实施例中，在步骤S11所述的在接收到用户的手动搜台指令后，在用户界面中显示频道对应表，具体可以为：
在接收到用户的手动搜台指令后，直接在用户界面中显示频道对应表。
相应的，在本申请另一个可行的实施例中，在步骤S11所述的在接收到用户的手动搜台指令后，在用户界面中显示频道对应表，具体还可以为：
在接收到用户的手动搜台指令后，在用户界面中显示提示图标，并在接收到用户对所述提示图标的选择操作后，显示频道对应表。
具体的，在频道管理器接收到手动搜台指令后，首先显示如图3所示的用户界面；其中，该用户界面中包含提示图标301。实际应用中，如果用户知道自己要搜索的目标节目对应的频道信息，可直接通过遥控器等输入该频道信息；即，此情况下不显示频道对应表，使得界面更简洁。如果用户不知道自己要搜索的目标节目对应的频道信息，则可以先通过遥控器的方向键选中该提示图标，再按下遥控器中表示确认选择的“确定”键(不同遥控器对应的键名可能不同，如部分遥控器中为“菜单”、“SET”等)，即相当于“点击”该提示图标301，从而触发频道管理器显示预存的频道对应表，如图4所示用户界面。
另外，如下表2所示，在本申请其他实施例中，频道对应表中还可以包括各个虚拟频道号对应的频道名称，如“中央电视台一套”等。
表2频道对应表

…   …
需要说明的是，本实施例表1、表2及图4所显示的频道对应表仅为示意本申请的核心理论，其具体数值可能与实际情况不同。
本申请实施例所述的频道对应表是预先存储在数字电视的频道管理器(或其他存储器件)中的。如图5所示，为得到该频道对应表，在本申请一个可行的实施例中，上述电视频道搜索控制方法还包括以下步骤：
S101、在首次执行自动搜台后，根据得到的自动搜索结果创建所述频道对应表。
电视首次开机时，一般会通过自动搜台对所有的数字信号传输频道进行遍历搜索；自动搜台结束后，可以得到大部分电视节目，将其频道信息按照对应关系 添加至所述频道对应表中，即可根据用户需求，在下次执行手动搜台时显示该频道对应表。
另外，数字电视出厂前，可以在设置默认频道对应表，该默认频道对应表中包含数字电视能接受到的各个物理频道列表。该默认频道对应表的作用在于，在数字电视首次开机或执行恢复出厂设置(所有节目信息被清空)后，用户直接执行手动搜台，不会因频道对应表不存在或为空表导致用户误以为电视存在故障。
进一步的，上述电视频道搜索控制方法还可以包括以下步骤；
S102、在每次执行自动搜台后，根据相应的搜索结果更新所述频道对应表。
鉴于虚拟频道号可能发生变化，故本申请实施例通过上述步骤S14对频道对应表进行更新，保证频道对应表中所存信息的准确性，进而保证手动搜台的效率及准确性。
另外，本申请实施例还提供了一种计算机存储介质，例如可以是只读存储器(Read-Only Memory，ROM)、随机存取存储器(Random-Access Memory，RAM)、光盘只读存储器(Compact Disc Read-Only Memory，CD-ROM)、磁带、软盘和光数据存储设备等；该计算机存储介质中存储有程序，当所述存储介质中的程序由数字电视的相关处理器执行时，使得该数字电视能够执行上述方法实施例中记载的任一种频道搜索控制方法中的部分或全部步骤。
相应于上述电视频道搜索控制方法，本申请实施例还提供了一种电视频道搜索控制装置，图6为该装置的结构框图。参照图6，该装置包括：频道对应表管理单元100、搜索执行单元200和搜索结果输出单元300。
其中，该频道对应表管理单元100用于，在接收到用户的手动搜台指令后，在用户界面中显示频道对应表，以便用户根据所述频道对应表确定目标节目对应的频道信息。其中，所述频道对应表至少记录有物理频道与虚拟频道号之间的对应关系，所述频道信息包括物理频道和虚拟频道号中的至少一种。
该搜索执行单元200用于，接收用户输入的频道信息，并根据所频道信息在相应的物理频道内进行搜索。
该搜索结果输出单元300用于，将搜索结果展示在所述用户界面中。
具体的，上述电视频道搜索控制装置可以在现有数字电视的频道管理器基础上改进得到；例如，在数字电视的现有频道管理器的基础上，增加上述频道对应表管理单元，上述搜索执行单元和搜索结果输出单元可以沿用现有频道管理器的相应模块。
由以上技术方案可知，本申请实施例在接收到用户的手动搜台指令后，显示预存的频道对应表，通过该频道对应表提示用户查找并输入自己要搜索的目标节目对应的频道信息，保证在准确的物理频道内进行搜索，从而可以提高手动搜台的搜索效率及成功率，避免出现搜索不到用户想看的目标节目甚至搜索不到任何节目的现象，提高用户体验好感度。
在本申请一个可行的实施方式中，为实现在接收到用户的手动搜台指令后，在用户界面中显示频道对应表，上述频道对应表管理单元100具体可以被配置为：在接收到用户的手动搜台指令后，直接在用户界面中显示频道对应表。
在本申请另一个可行的实施方式中，为实现在接收到用户的手动搜台指令后，在用户界面中显示频道对应表，上述频道对应表管理单元100具体还可以被配置为：
在接收到用户的手动搜台指令后，在用户界面中显示提示图标，并在接收到用户对所述提示图标的选择操作后，显示频道对应表。
此配置情况下，如果用户知道自己要搜索的目标节目对应的频道信息，可以不显示频道对应表，直接通过遥控器等输入该频道信息，使得界面更简洁；如果用户不知道自己要搜索的目标节目对应的频道信息，则用户可以选择上述提示图标，从而触发预存的频道对应表显示于用户界面中。
参照图4，在本申请一个可行的实施方式中，上述电视频道搜索控制装置还可以包括：频道对应表创建单元。该频道对应表创建单元用于，在首次执行自动搜台后，根据得到的自动搜索结果创建所述频道对应表。
在本申请另一个可行的实施方式中，上述电视频道搜索控制装置还可以包括：频道对应表更新单元；该频道对应表更新单元用于，在每次执行自动搜台后，根据相应的搜索结果更新所述频道对应表。
鉴于虚拟频道号可能发生变化，故本申请实施例通过上述频道对应表更新单 元对频道对应表进行更新，保证频道对应表中所存信息的准确性，进而保证手动搜台的效率及准确性。
可选的，实际应用中，上述频道对应表创建单元和频道对应表更新单元可以合并为一个单元，在数字电视首次启动时，执行频道对应表的创建，并在数字电视使用过程中，执行频道对应表的更新。
另外，本申请实施例还提供一种电视机；所述电视机包括：上文任一装置实施例所述的电视频道搜索控制装置。
本说明书中的各个实施例均采用递进的方式描述，各个实施例之间相同相似的部分互相参见即可，每个实施例重点说明的都是与其他实施例的不同之处。尤其，对于装置和系统实施例而言，由于其基本相似于方法实施例，所以描述的比较简单，相关之处参见方法实施例的部分说明即可。
以上所述的本发明实施方式，并不构成对本发明保护范围的限定。任何在本发明的精神和原则之内所作的修改、等同替换和改进等，均应包含在本发明的保护范围之内。
