具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
如图1所示，图1是本申请实施例方案涉及的硬件运行环境中智能电视的结构示意图。

本领域技术人员可以理解，图1中示出的终端结构并不构成对智能电视的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
如图1所示，作为一种计算机存储介质的存储器1005中可以包括操作系统、网络通信模块、用户接口模块以及频道扫描程序。
在图1所示的终端中，网络接口1004主要用于连接后台服务器，与后台服务器进行数据通信；用户接口1003主要用于连接客户端（用户端），与客户端进行数据通信；而处理器1001可以用于调用存储器1005中存储的频道扫描程序。
在本实施例中，智能电视包括：存储器1005、处理器1001及存储在所述存储器1005上并可在所述处理器1001上运行的频道扫描程序，其中，处理器1001调用存储器1005中存储的频道扫描程序时，执行本申请各个实施例提供的频道扫描方法的步骤。
本申请还提供一种方法，参照图2，图2为本申请方法第一实施例的流程示意图。
在本实施例中，该频道扫描方法包括：
步骤S10，当接收到频道扫描命令时，获取ATSC1.0标准的第一频点列表和ATSC3.0标准的第二频点列表；
步骤S20，将所述第一频点列表和所述第二频点列表中的各个频点依次设置为锁频频点，基于当前锁频频点对接收到的节目信号进行锁频。
在本实施例中，“数字电视”的含义并不是指我们家中的电视机，而是指电视信号的处理、传输、发射和接收过程中使用数字信号的电视系统或电视设备。其具体传输过程是：由电视台送出的图像及声音信号，经数字压缩和数字调制后，形成数字电视信号，经过卫星、地面无线广播或有线电缆等方式传送，由数字电视接收后，通过数字解调和数字视音频解码处理还原出原来的图像及伴音。因为全过程均采用数字技术处理，因此，信号损失小，接收效果好。
ATSC高级电视系统委员会，该委员会于1995年9月15日正式通过ATSC 数字电视国家标准，ATSC3.0是ATSC的最新规范，将Broadcast与Broadband有效结合。与ATSC1.0不同的是，ATSC3.0彻底重构了协议，充分采用了网络协议的标准，使用了MMTP、ROUTE(DASH) 协议传输音视频和文件。
在本实施例中，智能电视是指TV设备或者其他可接收ATSC1.0标准信号以及ATSC3.0标准信号的设备，智能电视进行频道扫描，进而获取各个频道的电视节目列表，而后收看相应的电视节目。具体地，智能电视包括调频器Tuner，也被称为频道选择器，Tuner根据锁频频点进行锁频，进一步地，当接收到频道扫描命令时，智能电视获取ATSC1.0标准的第一频点列表和ATSC3.0标准的第二频点列表，这两个表出厂时已经保存在智能电视的内部存储器或外部存储器中，然后将第一频点列表和第二频点列表中的各个频点依次设置为锁频频点，根据当前锁频频点对接收到的节目信号进行锁频。
需要说明的是，由于ATSC现网环境同时具有ATSC1.0标准的信号和 ATSC3.0标准的信号，所以需要利用ATSC1.0标准和 ATSC3.0标准的所有频点依次将接收到的ATSC信号进行锁频，获取频道信息以及节目信息，也就是说每次为Tuner设置一个锁频频点，Tuner根据锁频频点匹配接收到的ATSC信号，然后再为Tuner设置另外一个锁频频点，直至ATSC1.0标准和 ATSC3.0标准的所有频点被遍历。
进一步地，在一实施例中，步骤S20之后还包括：
步骤S30，当锁频成功时，获取当前锁频频点对应的节目参数，其中，节目参数包括节目数据和频道信息；
步骤S40，将当前锁频频点定义为历史频点，并关联存储所述历史频点及其对应的所述节目参数至预设存储区。
在本实施例中，锁频频点是Tuner的一个重要参数，Tuner用锁频频点去匹配接收到的ATSC信号，ATSC信号包括满足ATSC1.0标准的信号和满足ATSC3.0标准的信号，也就是说，当ATSC信号中存在与锁频频点匹配的信号时，锁频成功，也就是搜索到一个频道，否则，当ATSC信号不存在与锁频频点匹配的信号时，锁频不成功。需要说明的是，无论锁频是否成功，都将继续设置下一个锁频频点进行锁频，直至ATSC1.0标准和 ATSC3.0标准的所有频点被遍历设置为锁频频点，这样可以防止遗漏ATSC信号，影响频道扫描结果。
进一步地，当锁频成功时，智能电视获取节目参数，也就是获取节目数据及频道信息。具体地，Tuner锁定频点后，智能电视会下发与锁频成功的锁频频点相关的请求，从而获取节目数据及频道信息，接下来，保存锁频成功的锁频频点以及对应的节目数据和频道信息，将这些数据关联存储到预设的存储区。其中，预设存储区可以在智能电视的内置存储器中，也可以在智能电视的外部存储器中，也就是通过外部接口接入的外部存储设备，比如通过USB接口接入的优盘，关于预设存储区的具体位置，在本申请中不做限定。
需要说明的是，每次为智能电视的Tuner只设置一个锁频频点，如果锁频成功，那么智能电视就获取当前锁频频点对应的节目参数，并将当前锁频频点与其对应的节目参数保存到预设存储区中，当存在多次锁频成功时，需要将每次锁频成功的锁频频点及其对应的节目参数保存到预设存储区中。
当遍历将ATSC1.0标准和ATSC3.0标准的频点进行锁频后，根据预设存储区存储的节目参数，也就是节目数据和频道信息，生成节目列表。
举例说明，智能电视接收到的30个满足ATSC1.0标准的信号，其中有一个信号与频点473MHz相关，没有信号与频点393MHz相关；智能电视同时还接收到50个满足ATSC3.0标准的信号，50个信号中没有信号与频点473MHz和频点393MHz相关。当接收到频道扫描命令时，ATSC1.0标准的第一频点列表和ATSC3.0标准的第二频点列表中获取频点，然后将获取到的频点依次设置Tuner的锁频频点，当Tuner的锁频频点设置为473MHz进行锁频时，用473MHz去匹配接收到的ATSC信号，锁频可以成功，并可以成功获取到473MHz对应的节目数据及频道信息，而后将频点473MHz及其对应的节目数据及频道信息作为一条记录保存到预设存储区中。当Tuner的锁频频点设置为393MHz进行锁频时，锁频不成功，因为收到的所有ATSC信号中没有信号与频点393MHz相关，此时无需保存任何数据。
本实施例提出的频道扫描方法，当接收到频道扫描命令时，获取ATSC1.0标准的第一频点列表和ATSC3.0标准的第二频点列表，接下来将所述第一频点列表和所述第二频点列表中的各个频点依次设置为锁频频点，基于当前锁频频点对接收到的节目信号进行锁频，而后当锁频成功时，获取当前锁频频点对应的节目参数。通过遍历ATSC1.0标准和ATSC3.0标准中的所有频点进行锁频，避免遗漏节目信号，提升锁频效率，提升用户体验。
基于第一实施例，提出本申请方法的第二实施例，在本实施例中，步骤S30包括：
步骤S31，当锁频成功时，获取所述当前锁频频点对应的标准类型，并基于所述标准类型获取所述节目参数。
在本实施例中，ATSC1.0标准与ATSC3.0 标准没有兼容性，因此，当锁频频点锁频成功时，需要根据锁频频点对应的标准类型来确定获取节目数据和频道信息的方法。
具体地，当锁频成功时，锁频成功的当前锁频频点属于ATSC1.0标准时，智能电视发送获取PSIP 各表(如PAT、PMT、VCT)的请求给上游设备，上游设备根据请求进行处理并返回PSIP 各表至智能电视，智能电视根据获取到的PSIP各表以及ATSC1.0标准构建节目数据及频道信息；锁频成功的当前锁频频点属于ATSC3.0标准时，智能电视发送获取IP过滤包(包含SLT、S-TSID等)的请求给上游设备，上游设备根据请求进行处理并返回IP过滤包至智能电视，智能电视根据获取到的IP过滤包以及ATSC3.0标准构建节目数据及频道信息。
本实施例提出的频道扫描方法，当锁频成功时，获取所述当前锁频频点对应的标准类型，并基于所述标准类型获取所述节目参数，通过遍历ATSC1.0标准和ATSC3.0标准中的所有频点进行锁频，并根据具体的标准类型准确获取节目数据及频道信息，在避免遗漏节目信号的同时提升锁频效率，为用户带来良好体验。
基于第二实施例，提出本申请方法的第三实施例，在本实施例中，步骤S40之后还包括：
步骤S50，当所述第一频点列表和所述第二频点列表中的各个频点依次设置为锁频频点，并基于当前锁频频点对接收到的节目信号进行锁频的操作完成后，基于预设存储区中的节目参数生成频道节目列表。
在本实施例中，当频道扫描命令执行完成时，需要生成频道节目列表给用户，用户根据频道节目列表来选择频道及要收看的电视节目。因此，需要监测频道扫描状态，也就是监测ATSC1.0标准和ATSC3.0标准中的所有频点被遍历设置为锁频频点的状态。
具体地，当频道扫描过程还未结束，也就是没有完成全部锁频频点的锁频，需要继续从ATSC1.0标准的第一频点列表和ATSC3.0标准的第二频点列表中获取未被使用过的频点，然后将频点作为智能电视的Tuner的锁频频点进行锁频。
当ATSC1.0标准的第一频点列表和ATSC3.0标准的第二频点列表中的各个频点依次设置为锁频频点，并基于当前锁频频点对接收到的节目信号进行锁频的操作完成后，也就是频道扫描结束，根据预设存储区中保存的节目数据与频道信息的对应关系，生成频道节目列表。
本实施例提出的频道扫描方法，当所述第一频点列表和所述第二频点列表中的各个频点依次设置为锁频频点，并基于当前锁频频点对接收到的节目信号进行锁频的操作完成后，基于预设存储区中的节目参数生成频道节目列表。通过遍历ATSC1.0标准和ATSC3.0标准中的所有频点进行锁频，在避免遗漏节目信号的同时提升锁频效率，为用户带来良好体验。
基于第三实施例，提出本申请方法的第四实施例，在本实施例中，步骤S40之后还包括：
步骤S60，当接收到快速锁频命令时，基于所述快速锁频命令获取快速锁频频点，并基于所述快速锁频频点对接收到的节目信号进行锁频。
在本实施例中，当智能电视接收到快速锁频命令时，启动快速锁频模式，获取快速锁频模式对应的锁频频点，也就是快速锁频频点，然后根据快速锁频频点对接收到的ATSC节目信号进行锁频操作。具体地，Tuner用快速锁频频点去匹配接收到的ATSC信号，当ATSC信号存在与快速锁频频点匹配的ATSC1.0信号或ATSC3.0信号时，锁频成功，也就是搜索到一个频道，否则，当ATSC信号不存在与快速锁频频点匹配的ATSC1.0信号或ATSC3.0信号时，锁频不成功。无论锁频是否成功，都将继续设置下一个锁频频点进行锁频，直至快速锁频命令对应的所有频点被遍历设置为锁频频点。
需要说明的是，快速锁频频点也是ATSC1.0或ATSC3.0频段范围中的频点，快速锁频频点是保存在预设存储区中的频点，通过访问预设存储区获取。
本实施例提出的频道扫描方法，当接收到快速锁频命令时，基于所述快速锁频命令获取快速锁频频点，并基于所述快速锁频频点对接收到的节目信号进行锁频。通过遍历快速锁频命令对应的频点进行锁频，提高锁频速度，为用户带来良好体验。
基于第四实施例，提出本申请方法的第五实施例，参照图3，在本实施例中，步骤S60包括：
步骤S61，当接收到快速锁频命令时，确定预设存储区是否存在历史频点；
步骤S62，当所述预设存储区存在历史频点时，将历史频点设置为快速锁频频点，并基于所述快速锁频频点对接收到的节目信号进行锁频。
在本实施例中，当智能电视接收到快速锁频命令时，首先确定预设存储区是否存在历史频点，预设存储区保存的锁频频点是频道扫描命令启动过程中锁频成功的锁频频点，如果曾经启动过频道扫描命令且预设存储区没有被清空，那么预设存储区就存在历史频点，可以执行快速锁频命令对应的操作。
具体地，当所述预设存储区存在历史频点时，将历史频点设置为快速锁频频点，并基于快速锁频频点对接收到的节目信号进行锁频，也就是说，从预设存储区获取历史频点作为智能电视的Tuner的锁频频点，然后Tuner根据锁频频点匹配接收到的ATSC信号，接下来再为Tuner设置另外一个锁频频点，直至快速锁频命令对应的所有频点被遍历。
进一步地，在一实施例中，步骤S62之后还包括：
步骤S63，当锁频失败时，在预设存储区删除所述快速锁频频点及其对应的节目参数。
在本实施例中，当智能电视接收到快速锁频命令，并且预设存储区有历史频点时，获取历史频点作为快速锁频频点并进行锁频，虽然获取到的快速锁频频点是频道扫描命令对应的锁频成功的频点，但是由于频道切换等原因，可能导致利用快速锁频频点锁频失败，因此也要针对锁频失败情况进行处理。
进一步地，确定锁频是否成功，当用快速锁频频点匹配接收到的节目信号成功时，基于快速锁频频点与标准类型的对应关系，获取节目数据及频道信息，并更新预设存储区已保存的快速锁频频点对应的节目数据和频道信息；当所述锁频不成功时，说明当前ATSC信号中不存在与快速锁频频点匹配的节目信号，因此需要删除该快速锁频频点对应的记录，也就是在预设存储区删除快速锁频频点以及其对应的节目数据和频道信息。
进一步地，在一实施例中，步骤S61之后还包括：
步骤S64，当所述预设存储区不存在所述历史频点时，触发所述频道扫描命令。
在本实施例中，当预设存储区没有历史频点时，说明没有启动过频道扫描命令或者预设存储区被清空了，此时无法成功获取到快速锁频频点，也就无法执行快速锁频操作，则在预设存储区不存在历史频点时，触发频道扫描命令，执行频道扫描对应的操作步骤。
本实施例提出的频道扫描方法，当接收到快速锁频命令时，确定预设存储区是否存在历史频点，接下来当所述预设存储区存在历史频点时，将历史频点设置为快速锁频频点，并基于所述快速锁频频点对接收到的节目信号进行锁频。通过遍历快速锁频命令对应的频点进行锁频，提高锁频速度，同时实时更新锁频状态及相关数据，为用户带来良好体验。
此外，本申请实施例还提出一种计算机可读存储介质，所述计算机可读存储介质可以为非易失性可读存储介质。
本申请计算机可读存储介质上存储有频道扫描程序，所述频道扫描程序被处理器执行时实现如下操作：
