本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
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发明，并不用于限定本发明。
本发明提供一种逻辑频道号解析方法，参照图1，图1为本发明逻辑频道号解析方法第一实施例的流程示意图。
在本实施例中，该逻辑频道号解析方法包括以下步骤：
步骤S10，获取提供节目信号的运营商，并按照预设的频点依次进行搜台操作；
众所周知，在不同国家、不同地区为数字电视、数字电视机顶盒等终端提供节目信号内容的运营商也不同，有些地区甚至有多个运营商。不同运营商提供的节目信号内容不同，运营商提供的节目信号内容不同是指频道不同和/或属性参数不同，例如同一频点所对应的频道不相同。本实施例中，数字电视、数字电视机顶盒等终端内部设置有一逻辑频道号解析装置，或者数字电视、数字电视机顶盒等终端外接该逻辑频道号解析装置。其中，该终端包括但不限于数字电视、数字电视机顶盒等。
当终端进行节目搜索时，该逻辑频道号解析装置首先获取为终端提供节目信号的运营商。具体地，可根据用户选择的运营商，将其确定为为终端提供节目信号的运营商；或者根据当前进行节目搜索所对应的国家或地区自动获取为终端提供节目信号的运营商。也可以通过终端确定运营商后，将运营商发送至该逻辑频道号解析装置。本领域技术人员可以理解的是，获取运营商信息的方式在此不做限制。例如，用户可首先选择一个相应的国家，在接收到用户选择的国家时，获取该国家对应的运营商列表，运营商列表中包括选择的该国家的各个运营商。用户可基于该运营商列表，从中选择一个相应的运营商，逻辑频道号解析装置获取用户选择的该运营商。
步骤S20，在按照每个频点进行搜台操作时，获取当前频点的频道信息，从所述频道信息中提取逻辑频道号数据；
步骤S30，根据预存的所述运营商对应的逻辑频道号配置表解析所述逻辑频道号数据，获取所述逻辑频道号数据中包含的各个属性参数。
之后，当用户执行节目搜索操作，例如点击终端中预设的节目搜索控件时，视为终端接收到节目搜索指令。在接收到节目搜索指令时，终端进行搜台操作。具体地，终端可根据对应频段内的各个频点依次执行搜台操作，进行节目搜索。例如，锁定频段内的一个频点，根据用户设置的相应搜索参数基于锁定的当前频点进行节目搜索。
当搜索到节目信号时，获取当前频点对应的频道信息。其中，频道信息中包含了逻辑频道号数据，该逻辑频道号数据中包含了各个属性参数，包括业务ID(Service ID)、频道号(Logical channel number)、可见性(visible)、数字换台(only changed by numerical)、优先级(Priority)等。由于各个运营商均有其特定的逻辑频道号规则，不同的运营商，其对应的逻辑频道号规则不同。比如逻辑频道号数据中包含的属性参数不同，以及各个属性参数对应的起始比特位和所占比特位数不同。具体地，当搜索到节目信号时，接收服务器发送的当前频点对应的NIT(Network information table，网络信息表)和SDT(Service Description Table，业务描述表)等频道信息。然后，从接收到的NIT表和SDT表中提取当前频点对应的逻辑频道号数据。此处，需要说明的是，因为逻辑频道号数据通常包含在NIT表和SDT表里，故此处需要接收锁定频点的NIT表和SDT表。
进一步地，本实施例中，在所述步骤S10之前，还包括：
步骤a，依据各国家或地区各运营商不同的逻辑频道号规则，为不同运营商定制对应的逻辑频道号配置表并存储于数据库中。
在本实施例中，预先存储了各个运营商对应的逻辑频道号配置表。依据各国家或地区的各运营商所对应的不同的逻辑频道号规则，为不同运营商定制对应的逻辑频道号配置表，并将各个运营商对应的逻辑频道号配置表预存存于数据库中。每个运营商对应的逻辑频道号配置表中包含了逻辑频道号数据的各个属性参数、各个属性参数对应的起始比特位和所占比特位数、逻辑频道号数据所占总比特位数等。例如，如下表1所示：
表1：逻辑频道号配置表
Figure PCTCN2016085025-appb-000001
Figure PCTCN2016085025-appb-000002
在提取出当前频点对应的逻辑频道号数据时，根据预存的当前提供节目信号的运营商对应的逻辑频道号配置表解析当前频点对应的逻辑频道号数据，获取逻辑频道号数据中包含的各个属性参数。
本实施例提供的方案，在获取到提供节目信号的运营商后，通过预存的运营商对应的逻辑频道号配置表即可对逻辑频道号数据进行解析，针对于不同的运营商，不需要采用相应匹配的不同解析算法，因此，简化了逻辑频道号的解析操作。
进一步地，如图2所示，基于第一实施例提出本发明逻辑频道号解析方法第二实施例。在本实施例中，所述步骤S30包括：
步骤S31，在提取到所述逻辑频道号数据时，从数据库中查询是否存在所述运营商对应的逻辑频道号配置表；
步骤S32，在查询到所述运营商对应的逻辑频道号配置表时，根据所述运营商对应的逻辑频道号配置表解析所述逻辑频道号数据，获取所述逻辑频道号数据中包含的各个属性参数。
在本实施例中，当获取到当前频点对应的逻辑频道号数据时，先从预存的各个运营商对应的逻辑频道号配置表中查询是否存在当前获取的运营商对应的逻辑频道号配置表。本领域技术人员可以理解的是，也可以在获取到运营商后就查询是否存在当前获取的运营商对应的逻辑频道号配置表。在未查询到当前获取的运营商对应的逻辑频道号配置表时，则无法根据配置表解析 逻辑频道号数据来获取逻辑频道号数据中的各个属性参数，此时，可通过网络发送请求，从向运营商或电视厂商云端服务器下载该运营商的逻辑频道号配置表或逻辑频道号规则，以解析逻辑频道号。在查询到当前获取的运营商对应的逻辑频道号配置表时，则根据查询到的当前获取的运营商对应的逻辑频道号配置表解析当前频点对应的逻辑频道号数据，获取该逻辑频道号数据中包含的各个属性参数。具体地，所述步骤S32包括：
步骤b，获取所述运营商对应的逻辑频道号配置表中包含的各个属性参数对应的起始比特位和所占比特位数；
步骤c，根据获取的所述各个属性参数对应的起始比特位和所占比特位数解析所述逻辑频道号数据，确定所述逻辑频道号数据中的各个属性参数，其中，基于不同的运营商，逻辑频道号中各个属性参数对应的起始比特位和所占比特位数不同。
由于对于不同的运营商，逻辑频道号数据中各个属性参数对应的起始比特位和所占比特位数不同。本实施例中，在查询到当前获取的运营商对应的逻辑频道号配置表时，获取该运营商对应的逻辑频道号配置表中各个属性参数对应的起始比特位和所占比特位数。例如，获取业务ID(Service ID)对应的始比特位(Service ID first bit offset)和所占比特位数(Service ID total bits)，频道号(Logical channel number)对应的始比特位(Logical channel number first bit offset)和所占比特位数(Logical channel number total bits)，可见性(visible)对应的始比特位(Visible first bit offset)和所占比特位数(Visible total bits)，数字换台(only changed by numerical)对应的始比特位(Only changed by numerical bit offset)和所占比特位数(Only changed by numerical total bits)，优先级(Priority)对应的始比特位(Priority first bit offset)和所占比特位数(Priority total bits)等。然后根据获取的各个属性参数对应的起始比特位和所占比特位数解析当前频点对应的逻辑频道号数据，确定当前频点对应的逻辑频道号数据中的各个属性参数。例如，若获取到频道号(Logical channel number)对应的始比特位(Logical channel number first bit offset)为“****”位，所占比特位数(Logical channel number total bits)为4位，则解析出当前频点对应的逻辑频道号数据中从第“****”位开始的四位所对应的属性参数为频道号(Logical channel number)。
进一步地，在本实施例中，所述步骤S30之后，还包括：
步骤d，当存在已存业务ID与获取的所述属性参数中的业务ID一致，且所述已存业务ID关联的优先级低于获取的所述属性参数中的优先级时，以获取的所述属性参数更新所述已存业务ID关联的属性参数，其中，在当前进行锁频操作的频点为第一个进行锁频操作的频点时，将获取的各个属性参数关联保存；
步骤e，当已存业务ID与获取的所述属性参数中的业务ID均不同时，保存获取的所述属性参数。
当解析了当前频点对应的逻辑频道号数据，获取到逻辑频道号数据中包含的各个属性参数后，将各个属性参数关联保存。根据各个频点所对应的关联保存的属性参数即可获取频道列表，之后就不用再进行节目搜索操作。优选地，在第一次获取到频段内第一个频点所对应的逻辑频道号数据中的各个属性参数后，将第一次获取到频段内第一个频点所对应的逻辑频道号数据中的各个属性参数关联保存。之后，当提取频段内第二个频点对应的逻辑频道号数据，根据预存的获取的运营商所对应的逻辑频道号配置表解析出第二个频点对应的逻辑频道号数据中包含的各个属性参数后，比较解析获取的业务ID与保存的业务ID是否一致。若获取的业务ID与保存的业务ID不一致，则说明这两个频点对应的逻辑频道号数据是对应两个频道的，此时，将解析获取的第二个频点对应的逻辑频道号数据中包含的各个属性参数关联保存。若获取的业务ID与保存的业务ID一致，则说明这两个频点对应的逻辑频道号数据是对应同一个频道的。此时，再比较获取到的优先级与保存的优先级，当获取到的优先级高于保存的优先级时，以获取的各个属性参数更新关联保存的各个属性参数。当获取到的优先级低于保存的优先级时，则将获取的各个属性参数不进行关联保存。依此方法，在每次获取到当前频点对应的逻辑频道号数据时，根据预存的运营商对应的逻辑频道号配置表解析当前频点对应的逻辑频道号数据，获取逻辑频道号数据中包含的各个属性参数。当存在保存的业务ID与获取的业务ID一致，且与该业务ID关联保存的优先级低于获取的优先级时，以获取的各个属性参数更新关联保存的各个属性参数。直至对运营商的频段内的各个频点对应的逻辑频道号数据均进行解析，以获取该运营商对应的频道列表。
本实施例提供的方案，在进行节目搜索时，通过预存的运营商对应的逻辑频道号配置表即可对各个频点对应的逻辑频道号数据进行解析，简化了逻辑频道号的解析操作，从而提高了节目搜索的效率。
本发明进一步提供一种逻辑频道号解析装置，如图3所示，图3为本发明逻辑频道号解析装置第一实施例的功能模块示意图。
在本实施例中，该逻辑频道号解析装置包括：
搜索模块10，用于获取提供节目信号的运营商，并按照预设的频点依次进行搜台操作；
众所周知，在不同国家、不同地区为数字电视、数字电视机顶盒等终端提供节目信号内容的运营商也不同，有些地区甚至有多个运营商。不同运营商提供的节目信号内容不同，运营商提供的节目信号内容不同是指频道不同和/或属性参数不同，例如同一频点所对应的频道不相同。本实施例中，逻辑频道号解析装置设置于数字电视、数字电视机顶盒等终端内部，或者数字电视、数字电视机顶盒等终端外接该逻辑频道号解析装置。其中，该终端包括但不限于数字电视、数字电视机顶盒等。
当终端进行节目搜索时，该逻辑频道号解析装置的搜索模块10首先获取为终端提供节目信号的运营商。具体地，可根据用户选择的运营商，将其确定为为终端提供节目信号的运营商；或者根据当前进行节目搜索所对应的国家或地区自动获取为终端提供节目信号的运营商。也可以通过终端确定运营商后，将运营商发送至该逻辑频道号解析装置，搜索模块10获取终端发送的运营商信息。本领域技术人员可以理解的是，获取运营商信息的方式在此不做限制。例如，用户可首先选择一个相应的国家，在接收到用户选择的国家时，搜索模块10先获取该国家对应的运营商列表，运营商列表中包括选择的该国家的各个运营商。用户可基于该运营商列表，从中选择一个相应的运营商，搜索模块10获取用户选择的该运营商。
获取模块20，用于在按照每个频点进行搜台操作时，获取当前频点的频道信息，从所述频道信息中提取逻辑频道号数据；
解析模块30，用于根据预存的所述运营商对应的逻辑频道号配置表解析所述逻辑频道号数据，获取所述逻辑频道号数据中包含的各个属性参数。
之后，当用户执行节目搜索操作，例如点击终端中预设的节目搜索控件时，视为终端接收到节目搜索指令。在接收到节目搜索指令时，终端进行搜台操作。具体地，终端可根据对应频段内的各个频点依次执行搜台操作，进行节目搜索。例如，锁定频段内的一个频点，根据用户设置的相应搜索参数基于锁定的当前频点进行节目搜索。
当搜索到节目信号时，获取模块20获取当前频点对应的频道信息。其中，频道信息中包含了逻辑频道号数据，该逻辑频道号数据中包含了各个属性参数，包括业务ID(Service ID)、频道号(Logical channel number)、可见性(visible)、数字换台(only changed by numerical)、优先级(Priority)等。由于各个运营商均有其特定的逻辑频道号规则，不同的运营商，其对应的逻辑频道号规则不同。比如逻辑频道号数据中包含的属性参数不同，以及各个属性参数对应的起始比特位和所占比特位数不同。具体地，当搜索到节目信号时，获取模块20接收服务器发送的当前频点对应的NIT(Network information table，网络信息表)和SDT(Service Description Table，业务描述表)等频道信息，然后，从接收到的NIT表和SDT表中提取当前频点对应的逻辑频道号数据。此处，需要说明的是，因为逻辑频道号数据通常包含在NIT表和SDT表里，故此处需要接收锁定频点的NIT表和SDT表。
进一步地，本实施例中，该逻辑频道号解析装置还包括：
配置模块，用于依据各国家或地区各运营商不同的逻辑频道号规则，为不同运营商定制对应的逻辑频道号配置表并存储于数据库中。
在本实施例中，配置模块预先存储了各个运营商对应的逻辑频道号配置表。配置模块依据各国家或地区的各运营商所对应的不同的逻辑频道号规则，为不同运营商定制对应的逻辑频道号配置表，并将各个运营商对应的逻辑频道号配置表预存存于数据库中。例如，如表1所示，每个运营商对应的逻辑频道号配置表中包含了逻辑频道号数据的各个属性参数、各个属性参数对应的起始比特位和所占比特位数、逻辑频道号数据所占总比特位数等。
在获取模块20提取出当前频点对应的逻辑频道号数据时，解析模块30根据预存的当前提供节目信号的运营商对应的逻辑频道号配置表解析当前频点对应的逻辑频道号数据，获取逻辑频道号数据中包含的各个属性参数。
本实施例提供的方案，在搜索模块10获取到提供节目信号的运营商，获 取模块20获取到逻辑频道号数据后，解析模块30通过预存的运营商对应的逻辑频道号配置表即可对逻辑频道号数据进行解析，针对于不同的运营商，不需要采用相应匹配的不同解析算法，因此，简化了逻辑频道号的解析操作。
进一步地，如图4所示，基于第一实施例提出本发明逻辑频道号解析装置第二实施例。在本实施例中，所述解析模块30包括：
查询单元31，用于在提取到所述逻辑频道号数据时，从数据库中查询是否存在所述运营商对应的逻辑频道号配置表；
解析单元32，用于在查询到所述运营商对应的逻辑频道号配置表时，根据所述运营商对应的逻辑频道号配置表解析所述逻辑频道号数据，获取所述逻辑频道号数据中包含的各个属性参数。
在本实施例中，当获取模块20获取到当前频点对应的逻辑频道号数据时，查询单元31先从预存的各个运营商对应的逻辑频道号配置表中查询是否存在当前获取的运营商对应的逻辑频道号配置表。本领域技术人员可以理解的是，也可以在获取到运营商后就查询是否存在当前获取的运营商对应的逻辑频道号配置表。在未查询到当前获取的运营商对应的逻辑频道号配置表时，则解析单元32无法根据配置表解析逻辑频道号数据来获取逻辑频道号数据中的属性参数，此时，可通过网络发送请求，从向运营商或电视厂商云端服务器下载该运营商的逻辑频道号配置表或逻辑频道号规则，以解析逻辑频道号。在查询到当前获取的运营商对应的逻辑频道号配置表时，则解析单元32根据查询到的当前获取的运营商对应的逻辑频道号配置表解析当前频点对应的逻辑频道号数据，获取该逻辑频道号数据中包含的各个属性参数。具体地，所述解析单元32包括：
获取子单元，用于获取所述运营商对应的逻辑频道号配置表中包含的各个属性参数对应的起始比特位和所占比特位数；
解析子单元，用于根据获取的所述各个属性参数对应的起始比特位和所占比特位数解析所述逻辑频道号数据，确定所述逻辑频道号数据中的各个属性参数，其中，基于不同的运营商，逻辑频道号中各个属性参数对应的起始比特位和所占比特位数不同。
由于对于不同的运营商，逻辑频道号数据中各个属性参数对应的起始比 特位和所占比特位数不同。本实施例中，在查询到当前获取的运营商对应的逻辑频道号配置表时，获取子单元获取该运营商对应的逻辑频道号配置表中包含的各个属性参数对应的起始比特位和所占比特位数。例如，获取业务ID(Service ID)对应的始比特位(Service ID first bit offset)和所占比特位数(Service ID total bits)，频道号(Logical channel number)对应的始比特位(Logical channel number first bit offset)和所占比特位数(Logical channel number total bits)，可见性(visible)对应的始比特位(Visible first bit offset)和所占比特位数(Visible total bits)，数字换台(only changed by numerical)对应的始比特位(Only changed by numerical bit offset)和所占比特位数(Only changed by numerical total bits)，优先级(Priority)对应的始比特位(Priority first bit offset)和所占比特位数(Priority total bits)等。然后解析子单元根据获取的各个属性参数对应的起始比特位和所占比特位数解析当前频点对应的逻辑频道号数据，确定当前频点对应的逻辑频道号数据中的各个属性参数。例如，若获取子单元获取到频道号(Logical channel number)对应的始比特位(Logical channel number first bit offset)为“****”位，所占比特位数(Logical channel number total bits)为4位，则解析子单元解析出当前频点对应的逻辑频道号数据中从第“****”位开始的四位所对应的属性参数为频道号(Logical channel number)。
进一步地，在本实施例中，所述逻辑频道号解析装置还包括：
存储模块，用于当存在已存业务ID与获取的所述属性参数中的业务ID一致，且所述已存业务ID关联的优先级低于获取的所述属性参数中的优先级时，以获取的所述属性参数更新所述已存业务ID关联的属性参数，其中，在当前进行锁频操作的频点为第一个进行锁频操作的频点时，将获取的各个属性参数关联保存；当已存业务ID与获取的所述属性参数中的业务ID均不同时，保存获取的所述属性参数。
当解析模块30解析了当前频点对应的逻辑频道号数据，获取到逻辑频道号数据中包含的各个属性参数后，存储模块将获取的各个属性参数关联保存。根据各个频点所对应的关联保存的属性参数即可获取频道列表，之后就不用再进行节目搜索操作。优选地，在第一次获取到频段内第一个频点所对应的逻辑频道号数据中的各个属性参数后，存储模块将第一次获取到频段内第一 个频点所对应的逻辑频道号数据中的各个属性参数关联保存。之后，当提取频段内第二个频点对应的逻辑频道号数据，解析模块30根据预存的获取的运营商所对应的逻辑频道号配置表解析出第二个频点对应的逻辑频道号数据中包含的各个属性参数后，存储模块比较解析获取的业务ID与保存的业务ID是否一致。若获取的业务ID与保存的业务ID不一致，则说明这两个频点对应的逻辑频道号数据是对应两个频道的，此时，存储模块将解析获取的第二个频点对应的逻辑频道号数据中包含的各个属性参数关联保存。若获取的业务ID与保存的业务ID一致，则说明这两个频点对应的逻辑频道号数据是对应同一个频道的。此时，再比较获取到的优先级与保存的优先级，当获取到的优先级高于保存的优先级时，存储模块以获取的各个属性参数更新关联保存的各个属性参数。当获取到的优先级低于保存的优先级时，则将获取的各个属性参数不进行关联保存。依此方法，在每次接收到当前频点对应的逻辑频道号数据时，解析模块30根据预存的运营商对应的逻辑频道号配置表解析当前频点对应的逻辑频道号数据，获取逻辑频道号数据中包含的各个属性参数。当存在保存的业务ID与获取的业务ID一致，且与该业务ID关联保存的优先级低于获取的优先级时，存储模块以获取的各个属性参数更新关联保存的各个属性参数。直至对运营商的频段内的各个频点对应的逻辑频道号数据均进行解析，以获取该运营商对应的频道列表。
本实施例提供的方案，在进行节目搜索时，解析模块30通过预存的运营商对应的逻辑频道号配置表对各个频点对应的逻辑频道号数据进行解析，简化了逻辑频道号的解析操作，从而提高了节目搜索的效率。
以上仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
