其中, 所述补位码可以为 0或者 1。 具体的, 若所述最大值获取单元 2计 算得到的最大值为 16, 则对于卡号位仅为 10位的卡号 0123456789, 所述补位 操作, 即为: 0000000123456789, 从而使所述卡号的卡号位的长度与最大值相 等, 以 1作为补位码进行补充操作与以 0作为补位码时相同, 在此不赘述。 转换单元 4, 用于将所述智能卡卡号集合中各智能卡卡号分别转换为二进 制数组,所述二进制数组的长度值与所述计算单元 3计算得到的所述存放一个 智能卡卡号的二进制数组长度值相等, 其中,将各智能卡卡号转换为二进制数 组包括: 将各智能卡卡号的每两位转换为所述二进制数组中的一个字节。

图 2是本发明智能卡卡号处理方法的第一实施例的流程示意图。 如图 2 所示, 该方法具体可以包括:
S201 : 获取智能卡卡号的集合。 当数字电视系统中的消息播发系统需要对 各数字电视用户终端播发消息时, 所述消息播发系统创建完需要播发的消息 时, 可同时获取相应的一个或者多个数字电视用户终端的智能卡卡号。
S202: 获取所述智能卡卡号集合中智能卡卡号的长度值的最大值,并根据 所述最大值, 计算得到存放一个智能卡卡号的二进制数组长度值。
数字电视用户终端的智能卡卡号的长度并不完全相同, 包括 10位卡号位 的智能卡卡号或者 16位卡号位的智能卡卡号等, 具体的, 可通过对智能卡卡 号集合中的各智能卡卡号进行比较,得出所述智能卡卡号集合中智能卡卡号的 长度值的最大值。假设比较得出所述智能卡卡号集合中智能卡卡号的长度值的 最大值为 16, 则所述存放一个智能卡卡号的二进制数组长度值为: 16+1的和 值为 17, 17除以 2取整后结果为 8, 最后 8加上 1的结果为 9, 即用于存放一 个智能卡卡号的二进制数组长度值为 9, 其中所述二进制数组中包括长度值为 1的卡号长度表示位。
S203: 将所述智能卡卡号集合中各智能卡卡号分别转换为二进制数组,所 述二进制数组的长度值与计算得到的所述存放一个智能卡卡号的二进制数组 长度值相等, 其中, 将各智能卡卡号转换为二进制数组包括: 将各智能卡卡号 的每两位转换为所述二进制数组中的一个字节。

在方法第一实施例中,通过将播发消息对应的一个或多个智能卡卡号中各 智能卡卡号以每两位转换为二进制数组中的一个字节的方式转换为二进制数 组进行存储, 节省了存储空间。 另外, 由于将长度不同的智能卡卡号转换成长 度相等的二进制数组, 可方便简单的实现了智能卡卡号的拆分以及比较。
图 3 是本发明智能卡卡号处理方法的第二实施例的流程示意图。 如图 3 所示, 该方法具体可以包括:
S301 : 获取智能卡卡号的集合。 当数字电视系统中的消息播发系统需要对 个数字电视用户终端播发消息时, 所述消息播发系统创建完需要播发的消息 时, 可同时获取相应的一个或者多个数字电视用户终端的智能卡卡号。
S302: 获取所述智能卡卡号集合中智能卡卡号的长度值的最大值,并根据 最大值, 计算得到存放一个智能卡卡号的二进制数组长度值。
其中, 存放一个智能卡卡号的二进制数组长度值等于所述最大值加上 1 的和值除以 2的结果取整数后加 1。 具体的, 可通过对智能卡卡号集合中各智 能卡卡号的长度值进行比较以得到所述智能卡卡号集合中智能卡卡号的长度 值的最大值。根据所述最大值,通过将所述最大值加上 1的和值除以 2的结果 取整数后加 1得到存放一个智能卡卡号的二进制数组长度值。例如, 当长度值 的最大值为 16时, 通过((16+1 ) 12 ) +1计算可得到存放一个智能卡卡号的 二进制数组长度值为 9。
S303: 根据所述智能卡卡号集合中智能卡卡号的长度值的最大值,将所述 智能卡卡号集合中的各智能卡卡号的长度值与所述最大值进行比较,当存在智 能卡卡号的长度值小于所述最大值时,在长度值小于所述最大值的智能卡卡号 前面补充补位码以使小于所述最大值的智能卡卡号的长度值与所述最大值相 等。
具体的, 所述补位码可以为 0或者 1等数字, 以 0作为补位码为例, 可根 据所述智能卡卡号集合中智能卡卡号长度值的最大值与所述长度值小于所述 最大值的智能卡卡号的差值,在所述长度值小于所述最大值的智能卡卡号前面 补零,如,当最大值为 16时,对于卡号长度为 10位的智能卡卡号 0123456789, 根据最大值 16减去本智能卡卡号长度 10等于 6, 在智能卡卡号位前面补 6个 零, 从而将原智能卡卡号转换成为: 0000000123456789。
S304:将所述智能卡卡号集合中各智能卡卡号的每相邻的两位按先后顺序 相应的转换为二进制数组中的一个字节的前 4位和后 4位。
即使用二进制数组中的一个字节记录智能卡卡号的两个卡号位,分别以一 个字节的前 4 位和后 4 位记录相邻的两个智能卡卡号位, 如对于卡号为 0123456789ABCDEF 的智能卡, 以相邻的每两个卡号位为一组记录在二进制 数 组 中 , 二 进 制 数 组 为 : 1001101][11101111] ,其中第一个字节的二进制数组 [00010000]为卡号长度表示 位表示该二进制数组所对应的智能卡卡号长度为 16。 同理。 若智能卡卡号为 0123456789, 则先根据 S303步骤得到 0000000123456789, 然后釆用每两位记 录于二进制数组中一个字节中的形式, 将所述 0000000123456789转换为二进 制 数 值 , 则 所 述 二 进 制 数 组 为 :
1100111][10001001],其中,二进制数组的第一个字节 [00001010]为本智能卡卡 号长度表示位, 即表示本二进制数组所对应的智能卡卡号的长度为 10。
S305: 存储所述二进制数组。
具体实现中,将所述记录智能卡卡号所对应的二进制数值的数据库消息表 存储在存储介质中。
S306: 根据所述计算得到存放一个智能卡卡号的二进制数组长度值, 并根 据所述二进制数组中的卡号长度表示位对存储的所述二进制数组进行拆分,得 到对应的各智能卡卡号。
具体的,根据所述计算得到的存放一个智能卡卡号的二进制数组长度值将 智能卡卡号集合转换而成的二进制数组依次拆分成定长的二进制数组,同时根 据所述二进制数组的第一个字节即卡号长度表示位,确定本二进制数组记录的 智能卡卡号的长度值, 以相应的去掉添加在智能卡卡号前面的补位码, 如 0 或 1 , 从而正确的根据二进制数组还原智能卡卡号。
S307: 将录入的智能卡卡号分别与拆分出的各智能卡卡号进行比较, 以判 断所述录入的智能卡卡号是否在所述智能卡卡号集合中。
具体的,将录入的智能卡卡号与拆分还原的智能卡卡号进行比较, 若存在 与所述录入的智能卡卡号相同的智能卡卡号,则判断出所述录入的智能卡卡号 在所述智能卡卡号集合中。
另外, 上述的对二进制数组的拆分, 以及相应的比较的步骤, 也可以釆用 将所述二进制数组集合拆分为定长的二进制数组,并将用户录入的智能卡卡号 按照前述规则转换成相应的二进制数组,将由用户录入的智能卡卡号转换而成 的二进制数组与拆分为定长的二进制数组进行比较,也可查询出用户录入的智 能卡卡号是否在所述智能卡卡号集合中。
在方法第二实施例中,将播发消息对应的一个或多个智能卡卡号中各智能 卡卡号以相邻的每两卡号位转换为二进制数组中的一个字节的形式转换成定 长的二进制数值进行存储, 节省了存储空间。 另外, 长度不统一的数字电视用 户终端的智能卡卡号以补充补位码的方式转换成定长的二进制数组并组合存 储, 可方便简单的实现智能卡卡号的拆分以及比较。
以上所揭露的仅为本发明的较佳实施例而已,当然不能以此来限定本发明之权 利范围, 因此依本发明权利要求所作的等同变化, 仍属于发明所涵盖的范围。
