机顶盒加载驱动的方法及系统 技术领域
本公开涉及机顶盒技术领域，例如涉及一种机顶盒加载驱动的方法及系统。
背景技术
通常说的机顶盒升级程序(loader)，一般由两部分组成，一部分负责引导浏览器/服务器(Browser/Server，简称“BS”)，一部分负责启动装载(BootLoader，简称“BL”)。BS是机顶盒开机起来后执行的第一段程序，他首先判断有无升级程序，如果有升级程序则执行升级程序中的BL，没有升级程序则执行机顶盒中的应用程序(Application，简称“APP”)。
为了满足人们日益增长的生活水平，增加更多更丰富的内容及修正原有机顶盒中的bug，对已经出厂后的机顶盒进行升级显得尤其重要，因此loader已成为机顶盒中必不可少的一部分。市场上绝大多数的机顶盒loader包含各种驱动程序。在实际生活中，机顶盒厂商经常会遇到这种情况：已经生产出货的机顶盒如果运营商或者消费者比较满意，会继续和机顶盒厂商合作，为了减少研发费用并大大缩短研发周期，他们会要求机顶盒厂商在此机顶盒的基础上对硬件稍作修改。
然而，目前普遍使用的机顶盒，其驱动程序与上层应用程序存储在一起。当硬件的细微改动导致驱动程序更改时，上层应用程序也需要相应的修改，导致了开发及测试的人员成本增加。同时，带高安功能的机顶盒都要发给CA(Conditional Access，条件接收)公司认证，认证后的机顶盒如果有任何改动需要重新认证，认证过程需要时间，也需要重新缴纳认证费用，延长了生产周期，同时增加生产成本。

具体实施方式
为使本公开采用的技术方案更加清楚，下面将结合附图对本公开实施例的技术方案作详细描述，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。在不冲突的情况下，以下实施例以及实施例中的技术特征可以相互任意组合。
实施例一
本公开实施例中，通过将机顶盒硬件的更新驱动程序与上层应用程序分开存储，将更新驱动程序对应的硬件信息以及存储地址采用配置文件形式存储于flash内。当机顶盒启动时，通过查找flash内的配置文件，根据配置文件判断是否存储更新程序，当存储更新程序时对相应的硬件信息进行更新。这样解决了现有的机顶盒在换硬件后需要 重新修改上层应用程序，导致的开发和测试上的人力成本以及需要重新认证的缺陷的问题。
请参见图1，图1为本公开提供一种机顶盒加载驱动的方法的实施例一的流程图。所述方法包括：
步骤101、机顶盒启动时，查询flash中是否存储配置文件，其中，配置文件至少存储有配置选项及驱动程序地址。
具体地，当机顶盒启动系统的时候，首先查找flash中是否存储有配置文件。也就是说，在启动系统时，首先判断机顶盒中是否存在需要更新的硬件。
在本实施例中，所述配置文件内至少配置有配置选项和驱动程序地址，所述配置选项用于配置需要更新的硬件名称，如tuner硬件、遥控器、网口、av、dmd或者smart模块等，可以根据配置选项确定需要更新的硬件。所述驱动程序地址表示配置选项中配置的硬件的更新驱动程序的存储地址，根据所述驱动程序地址可以获取该更新驱动程序。从而，在查询flash内存储的配置文件之前，还应该包括一个驱动程序存储及配置文件生成的过程，其具体包括：
步骤10、将机顶盒中需要更新的驱动程序单独存储，以使所述需要更新的驱动程序和应用功能分开。
步骤20、根据所述需要更新的驱动程序对应的硬件名称，及所述更新的驱动程序的存储地址生成配置文件，并将所述配置文件存储与flash内。
具体地，所述配置文件文件内配置需要升级的硬件信息以及用于升级该硬件的驱动程序的存储地址。在实际用于中，所述硬件更新的驱动程序可以从厂家或者网站，并将获取的文件存储于flash内，并与应用程序分离存储。
步骤102、若查询到配置文件时，读取所述配置文件中的配置选项，并根据所述配置选项判断是否需要更新驱动程序。
具体地，若查询到配置文件时，读取所述配置文件中的配置选项。所述配置选项内存储有需要更新的硬件信息，根据所述配置文件可以判断是否需要采取外部的驱动程序来初始化硬件。例如，所述配置选项中配置了更新tuner的驱动选项，那么确定需要更新tuner的驱动之后才能完成驱动程序初始化，加载系统应用。如果配置文件的配置选项内配置需要采用外部的驱动程序来初始tuner，那么就采用系统默认的驱动初始化硬件。值得说明的，所述配置选项中可以配置一个需要更新的硬件，可以配置多个需要更新的硬件以及每个硬件对应的新的驱动程序的存储地址。所述配置选项中的硬件可以为av，遥控器，网口，dmd或smart模块等。
步骤103、若需要更新驱动程序时，根据配置文件中的驱动程序地址获取与应用程序分离存储的更新驱动程序。
具体地，若需要更新驱动程序时，那么就根据驱动程序地址调用与应用程序分离存储的驱动程序，初始化硬件。如tuner需要更新驱动，那么根据配置文件中的新的tuner的驱动的地址，从flash中读取新的tuner的驱动程序，来初始配置tuner硬件。当配置选项中配置多个需要更新的硬件时，依次根据所述需要更新的硬件获取配置文件中与其对应的新的驱动程序的存储地址，根据存储地址获取相应的驱动程序，对其进行更新。当配置选项中所配置的所有需要更新的硬件的驱动程序都更新完成后，加载系统应用。
在本实施例中，在所述系统采用更新后的驱动初始化硬件，并加载系统应用之后还可以包括一个验证过程，其具体包括：
判断更新后的驱动是否能正常工作；
如果判断出能正常工作，则提示替换硬件成功；
如果判断出不能正常工作，则提示替换硬件失败。
本实施例提供的机顶盒加载驱动的方法，所述方法包括机顶盒启动时，查询flash中是否存储配置文件；若查询到配置文件时，读取 所述配置文件中的配置选项，并根据所述配置选项判断是否需要更新驱动程序；若需要更新驱动程序时，根据配置文件中的驱动程序地址获取驱动程序。本申请通过查询flash内的配置文件，根据配置文件内存储的配置选项和驱动地址，加载存储与外部的更新驱动，更新配置选项内配置的硬件的驱动，实现了驱动与上层应用的分离，解决现有的机顶盒在换硬件后需要重新修改上层应用程序，导致的开发和测试上的人力成本以及需要重新认证的缺陷的问题。
为了进一步理解本公开提供的加载机顶盒驱动的方法，下面结合几个实例做进一步说明。
实施例二
本实施例提供了一种机顶盒加载驱动的方法，如图2所示，其包括：
步骤201、机顶盒启动时，以一个block为步长查询flash中该block长度数据中是否存在指定字符串，若查询到flash中存在指定字符串，则执行步骤202；若未查询到flash中存在指定字符串，则执行步骤206。
具体地，Flash存储器中包括若干个block，其中，block的中文简称为块。当机顶盒启动时，以flash存储器中的block为单位按顺序查询flash中存储的内容。也就是说，每次查询一个block内的数据，判断所述block存储的数据内是否存在指定字符串。在实际应用中，可以将flash以block为步长，按照数据存储顺序划分为若干杆数据块，分别为第一数据块，第二数据块，......，第n数据块，按照数据块的编号顺序依次查询各数据块内是否存储指定字符串。
所述按照数据块的编号顺序依次查询各数据块内是否存储指定字符串的具体过程为：首先查询第一数据块内没有存储指定字符串，如果第一字符存在指定字符串，则完成查询。如果第一数据块内没有查询到指定字符，则查询第二数据块，如果查询到则完成查询，如果 未查询到则依次按照编号顺序循环查询所有数据块。
所述指定字符串为系统需要设置的，如，123456789”。所述字符串用于标示该数据块内可能存在配置有需要升级硬件信息及相应更新驱动程序的配置文件。对于不同的厂商的机顶盒所述指定字符串可以相同也可以不同。
所述未查询到flash中存在的指定字符串指的是所有数据块全部查询完，没有查询到指定字符串。当没有查询到指定字符串时，说明flash内没有存储配置文件，也就是没有需要升级的硬件，则采用默认驱动初始化硬件。并且当硬件初始化完成后，加载系统应用程序，机顶盒正常运行。
步骤202、确定包含该指定字符串的block为配置文件，结束flash内容的查询。
步骤203、读取所述配置文件中的配置选项，根据所述配置选项确定是否需要更新驱动程序；当需要更新驱动程序时，执行步骤204；当不需要更新驱动程序时，执行步骤205。
步骤204、根据配置文件中的驱动程序地址获取与应用程序分离存储的更新驱动程序，初始化硬件。
步骤205、采用默认的驱动初始化硬件。
本实施例提供的一种机顶盒加载驱动的方法，其在以block为步长在flash内查询预先设定的指定字符串的方法确定配置文件，其操作简单，减少机顶盒启动的时间。
实施例三
一种机顶盒加载驱动的方法，如图3所示，其包括：
步骤301、机顶盒启动时，以一个block为步长查询flash中该block长度数据中是否存在指定字符串，若查询到flash内容中存在指定字符串，则执行步骤302；若未查询到flash内容中存在指定字符串，则执行步骤306。
步骤302、获取所述字符串所属的block内的crc值。
步骤303、将所述crc值与存放于所述block尾部的四个字节数值进行比较，若相同，则执行步骤304；若不同，则执行步骤301。
步骤304、确定包含该指定字符串的block为配置文件；
步骤305、读取所述配置文件中的配置选项，并根据所述配置选项判断是否需要更新驱动程序，当需要更新时，执行步骤306；当不需要更新时，执行步骤307。
步骤306、根据配置文件中的驱动程序地址获取与应用程序分离存储的更新驱动程序，初始化硬件。
步骤307、采用默认的驱动初始化硬件。
本实施例提供的一种机顶盒加载驱动的方法，其在通过指定字符串查询配置文件后，进一步对包含所述指定字符串的block进行crc计算，将crc值与block尾部的四个数值进行比较，如果相同才确定该文件为配置文件。提高了配置文件的准确性，保证了硬件更新驱动加载的成功率。
本公开还提供了一种机顶盒加载驱动的系统，如图4所示，其包括：
