节目更新方法及多模机顶盒 技术领域
本公开涉及机顶盒技术领域，例如涉及一种节目更新方法及多模机顶盒。
背景技术
伴随着数字电视标准的推广和普及，多模机顶盒产业得到迅速的发展。目前很多国家包括中国的数字电视基本采用的都是欧洲的数字视频广播(Digital Video Broadcasting，DVB)标准，已经有些厂家开始尝试研发具有混合型接收功能的多模机顶盒产品，这种多模机顶盒产品硬件上具有多个调谐器和解调模块，这些调谐器和解调模块可以同时工作，分别负责数字卫星电视系统(DVB-Satellite，DVB-S)，数字有线电视系统(DVB-Cable，DVB-C)，数字地面电视广播系统(DVB-Terrestrial，DVB-T)信号的接收和解调，并把解调后的数字信号经过解复用模块和解码模块后，把得到的音视频信号经过数模转换传送给模拟电视，或直接把音视频信号经高清晰多媒体接口(High Definition Multimedia Interface，HDMI)输出至高清电视。
多模机顶盒的兴起，相对传统单一前端型多模机顶盒来说电视节目数目会翻几倍，用户在切换节目时，可能需要在成百上千套节目中进行上下切换操作。在使用时，可能会出现多模机顶盒一根或多根信号线没有连接的情况，那么在切换到节目时，多模机顶盒首先会从数据库中查找该节目对应的前端和频点信息，重新配置前端后尝试搜索信号，如果正好该节目是由断开的前端搜索到的节目，那么多模机顶盒有可能会连续多次搜索直至超时才放弃，增加了用户找 到可观看节目的时间，系统运行准备效率低。

具体实施方式
图1为本实施例提供一种节目更新方法的流程图，该方法可以应用于多模机顶盒，如图6所示，多模机顶盒610与前端系统620通信连接，其中，多模机顶盒与前端系统可以通过信号线进行连接也可以通过无线的方式进行连接，多模机顶盒中存储有节目列表，如图1所示，该方法可以包括：

例如，每个一预定时间，如1分钟，机顶盒获取前端系统的至少一个前端信号的通信状态的变化信息，当所述前端系统包括一个前端信号时，获取该前端信号的所述变化信息，当所述前端系统包括多个前端信号时，可以逐一获取各个前端信号的所述变化信息，当一前端信号的所述变化信息为从连接变为断 开时，则在列表中删除相应的节目，当一前端信号的所述变化信息为从断开变为连接时，则在列表中增加相应的节目，每次更新后的列表作为当前节目列表，并提供给用户，用户可以对当前节目列表提供的节目进行切换等操作。
本实施例提供的方法，可以实现在多模机顶盒与前端信号的连接状态发生变化时，及时更新多模机顶盒的节目列表，保证为用户提供有效的节目，减少了用户不必要的等待时间，提高系统的运行效率。
可选地，所述根据所述变化信息，获取通信状态发生变化的前端信号对应的节目信息的步骤包括：当所述变化信息为从连接变为断开时，获取通信状态变为断开的前端信号对应的第一节目信息；所述根据所述节目信息，更新所述节目列表为当前节目列表的步骤包括：通过过滤所述节目列表中的所述第一节目信息，更新所述节目列表为当前节目列表。
例如，获取通信状态从连接变为断开的前端信号对应的第一节目信息，其中，第一节目信息包括通信状态变为断开的前端信号所提供的至少一个节目，从多模机顶盒的节目列表中删除第一节目信息对应的至少一个节目，实现对节目列表的更新，可以及时过滤无效的节目，减少搜索节目时耗费的时间，减少用户不必要的等待时间，提高系统的运行效率。
可选地，所述根据所述变化信息，获取通信状态发生变化的前端信号对应的节目信息的步骤包括：当所述变化信息为从断开变为连接时，获取通信状态变为连接的前端信号对应的第二节目信息；所述根据所述节目信息，更新所述节目列表为当前节目列表的步骤包括：通过添加所述第二节目信息至所述节目列表，更新所述节目列表为当前节目列表。
例如，获取通信状态从断开变为连接的前端信号对应的第二节目信息，向多模机顶盒的节目列表中增加第二节目信息对应的至少一个节目，实现对节目 列表的更新，可以及时将有效的节目加入到节目列表中，保证为用户提供丰富的可选节目，改善用户的使用体验。
图2为本实施例提供的一种多模机顶盒，多模机顶盒与前端系统通信连接，多模机顶盒中存储有节目列表，如图2所示，该多模机顶盒可以包括：
状态变化获取模块210，设置为每隔一预定时间，获取所述前端系统的至少一个前端信号的通信状态的变化信息，所述变化信息包括从连接变为断开和从断开变为连接；
节目信息获取模块220，设置为根据所述变化信息，获取通信状态发生变化的前端信号对应的节目信息；
更新模块230，设置为根据所述节目信息，更新所述节目列表为当前节目列表。
可选地，所述节目信息获取是设置为当所述变化信息为从连接变为断开时，获取通信状态变为断开的前端信号对应的第一节目信息；
所述更新模块是设置为通过过滤所述节目列表中的所述第一节目信息，更新所述节目列表为当前节目列表。
可选地，所述节目信息获取还设置当所述变化信息为从断开变为连接时，获取通信状态变为连接的前端信号对应的第二节目信息；
所述更新模块还设置为通过添加所述第二节目信息至所述节目列表，更新所述节目列表为当前节目列表。
图3a为本实施例提供的一种多模机顶盒节目过滤方法的流程图，多模机顶盒与前端系统通信连接，所述多模机顶盒中存储有节目列表，如图3a所示，该方法可以包括步骤310-步骤330。
在步骤310中，每隔一预定时间，获取至少一个前端信号的当前连接状态。
以多模机顶盒通过前端信号线与前端信号进行通信连接为例，在多模机顶盒启动后，每隔一预定时间获取与多模机顶盒连接的至少一个前端信号线的连接状态，还可以存储所述前端信号线的连接状态。
其中，多模机顶盒的模式可以包括3种，如DVB-S卫星传输，DVB-C有线传输，DVB-T地面传输。若当前3种模式的前端信号都处于连接状态，则每个前端类型搜索到的节目累加在一起构成节目列表。多模机顶盒每隔一预定时间获取至少一个前端信号线的连接状态并存储起来，用于和下次获取的前端信号线的连接状态进行比较。其中，预定时间可以为1分钟～3分钟。
可选地，在步骤310之前还包括：存储所述多模机顶盒中的至少一个前端信号的连接状态的状态值。
例如，可以预先在多模机顶盒中设置一寄存器，在该寄存器中存储上述三个前端信号的连接状态，分别用不同的状态值表示不同的连接状态。当前端信号与机顶盒连接状态发生变化时，寄存器中存储的状态值也将对应变化，上述寄存器也可以设置在多模机顶盒外部，与多模机顶盒通信连接。
可选地，如图3b所示，步骤310可以包括步骤312-步骤314。
在步骤312中，每隔一预定时间，获取所述至少一个前端信号的连接状态的当前状态值。
例如，多模机顶盒启动后，每隔一预定时间读取多模机顶盒中的寄存器中的至少一个前端信号线的当前状态值；
在步骤314中，根据所述当前状态值解析出所述至少一个前端信号的当前连接状态。
例如，根据寄存器中的状态值解析出多模机顶盒中的至少一个前端信号线的连接状态，还可以存储解析结果。再例如，多模机顶盒启动后，每隔3～5min 从多模机顶盒中的寄存器中读取数据，分析寄存器中对应的信号连接状态值并存储。
在步骤320中，检测到所述至少一个前端信号的当前连接状态相比所述至少一个前端信号的前一连接状态发生变化时，获取所述连接状态处于断开的前端信号。
例如，每次获取到前端信号线的当前连接状态后，均和对应的信号线的前一次的连接状态进行对比，检测到当前获取的各个前端信号线的连接状态相比前一次获取的各个前端信号线的连接状态发生变化，根据寄存器中的信号连接状态参数确定当前处于连接状态，断开状态对应的前端信号，获取信号连接状态处于断开的前端信号。
可选地，在步骤320之后还包括步骤322。
在步骤322中，当检测到所有前端信号的连接状态都处于断开状态时，发送所有信号线处于断开状态的提示信息。
例如，当检测到多模机顶盒中所有前端信号线都处于断开状态时，多模机顶盒生成提示信息，发送给显示设备，在显示菜单中提示用户所有信号线处于断开状态。
在步骤330中，在所述节目列表中过滤掉所述连接状态处于断开的前端信号对应的节目。
例如，获取多模机顶盒的节目数据库中的原始节目，从原始节目中过滤掉断开的前端信号线对应的节目，其中原始节目包括多有前端信号线对应的节目，根据解析出的当前状态处于断开的前端信号线，从节目数据库的全部节目信息中过滤掉连接状态变为断开的前端信号线对应的节目，剩下的节目为正常连接的节目，实现排除没有信号连接的节目，减少了用户切换可看节目的时间。
可选地，如图3c所示，步骤330可以包括步骤332-步骤334。
在步骤332中，在接收到预设指令时，更新所述节目列表。
例如，根据用户输入的操作指令，对多模机顶盒中节目数据库的节目进行更新。
在步骤334中，获取更新后的节目列表中的节目；过滤掉所述更新后的节目列表中所述连接状态处于断开的前端信号对应的节目。
例如，获取更新后的节目数据库中的原始节目，在原始节目中过滤掉断开的前端信号线类型对应节目生成目标节目，还可以将目标节目作为多模机顶盒切换节目或显示节目列表时的节目源。
多模机顶盒可以分配两个内存空间A和B，上述步骤可以由任务一和任务二组成，启动任务一，任务一检查节目数据库是否有更新，数据库更新的原因包括用户搜索节目或编辑节目(如用户删除了某节目)，当数据库更新时，刷新内存A中的节目信息，保证内存A中是最新的所有节目，同时发送节目信息有变化的消息给任务二。启动任务二，任务二收取前端信号的当前连接状态信息和任务一的消息，发送内存A中的数据到内存B中，使内存B中存储当前节目数据库最新的所有节目，分析前端信号的当前连接状态消息，解析出当前连接状态处于断开的前端信号，过滤掉内存B的全部节目信息中上述连接状态为断开的前端信号对应节目。
实时地更新内存B中的节目，保证内存B中的节目信息均为连接正常的节目，当用户全屏切换节目或显示节目列表时，机顶盒所提供的节目信息都来自内存B中的节目，排除没有信号连接的节目，减少了用户切换可观看的节目的时间。假如当前所有前端的信号线都没有连接，那么内存空间B中也将不含有任何节目信息，多模机顶盒生成提示信息，通过菜单系统，使显示设备显示提 示信息，提示用户所有信号线都没有连接，需要连接信号线才能播放节目。
本实施例还提供另一种多模机顶盒节目过滤方法的流程图，以多模机顶盒的音乐播放器应用为例，如图4所示，该方法包括如下步骤：
在步骤10中，开始，即开启机顶盒；
在步骤12中，分配内存空间A和B，之后执行步骤14和步骤24；
在步骤14中，启动任务一；
在步骤16中、监视数据库节目；
在步骤18中，判断数据库中的节目是否有更新，若是，则执行步骤20，若否，则返回执行步骤16；
在步骤20中，更新内存空间A中节目内容；
在步骤22中，发送消息至任务二；
在步骤24中启动任务二；
在步骤26中，接收任务一和前端信号连接状态的监控消息；
在步骤28中，判断是否收到消息，若是，则执行步骤30，若否，则返回执行步骤26；
在步骤30中，发送内存A中内容至内存B；
在步骤32中，解析前端信号的连接状态消息，并获取连接状态为断开前端信号；
在步骤34中，过滤内存B中连接状态为断开前端信号对应的节目数据；
在步骤36中，判断内存B中节目个数是否为零，若是，则执行步骤38，若否，则执行步骤26；
在步骤38中，发送提示信息至显示设备，以使显示设备通过节目菜单提示用户插入信号线，并返回执行步骤26。
通常多模机顶盒对前端信号提供的全部节目呈现给用户，用户可以手动选择选择要过滤的前端类型对应的节目，多模机顶盒无法自动对前端信号对应的节目过滤，当用户切换节目时，多模机顶盒会从数据库中查找该节目对应的前端信号和频点信息，重新配置前端后尝试搜索信号，如果正好该节目是由断开的前端搜索到的节目，那么多模机顶盒有可能会连续多次搜索直至超时才放弃，耗费时间较长，如果连续用户切换的多个节目都是由于信号线断开的原因都没有信号，则会耗费更多搜索节目的时间。
本实施例中，能够实时监测当前多模机顶盒每个前端信号的连接状态，自动过滤掉没有信号线连接的节目，可以保证在全屏切换节目、或通过遥控器显示节目列表并在节目列表中上下切换节目时，不会出现因为信号线连接问题而导致的提示没有信号的情况。减少多模机顶盒因节目无效而多次尝试搜索节目的次数，不仅提高了系统运行的效率，还可以减少用户的等待时间。并且不需要用户对DVB传输标准有一定的了解，也不需要通过菜单去选择前端类型，就可以自动过滤无效的节目，真正做到老少皆宜，易使用，更智能。
