向机顶盒提供用于提示认证失败的页面。 优选地， 页面提供单元还用于在认证单元对认证请求认证失败后提供用 于提示重新输入认证信息或切换至其他频道的页面。 优选地， 设置单元还用于将频道列表中的播放预定频道需要的信息进行 力。密以作为认证信息； 发送单元还用于在认证单元认证成功后， 发送解密后 的播放频道所需要的信息。 才艮据本发明的另一方面， 提供了一种频道切换认证方法， 包括： 为频道 列表中的预定频道设置认证信息； 接收在用户切换到设置有认证信息的频道 时机顶盒发送的认证请求； 对认证请求进行认证； 在认证成功后， 发送播放 频道所需要的信息。 优选地， 为频道列表中的预定频道设置认证信息包括： 将认证页面地址 设置为预定频道的认证信息， 其中， 认证页面地址中携带有该频道的频道标 识； 接收认证请求包括： 在用户切换到设置有认证页面地址的频道时， 向机 顶盒提供认证页面地址对应的认证页面， 并通过认证页面用于接收机顶盒发 送的认证请求。 优选地， 在对认证请求进行认证之后， 上述方法还包括： 在认证失败的 情况下， 向机顶盒提供以下页面的至少之一： 用于提示认证失败的页面、 用 于提示重新输入认证信息的页面、 用于提示切换至其他频道的页面。 优选地， 在接收认证请求之前， 上述方法包括： 机顶盒根据本地保存的 进行认证所需要的信息发送认证请求。 优选地， 上述方法还包括： 频道列表中包括有未设置认证标识的频道的 频道地址； 在切换至未设置认证标识的频道时， 机顶盒 居未设置认证标识 的频道的频道地址播放。 通过本发明， 釆用为需要进行切换认证的频道设置认证信息， 以对该频 道进行切换认证， 解决了相关技术中业务系统需要对每次切换都进行认证而 导致增大业务系统压力的问题， 进而降低了业务系统压力。 附图说明 此处所说明的附图用来提供对本发明的进一步理解， 构成本申请的一部 分， 本发明的示意性实施例及其说明用于解释本发明， 并不构成对本发明的 不当限定。 在附图中： 图 1是 居本发明实施例的频道切换认证装置的结构框图； 图 2是 居本发明实施例的频道切换认证装置优选的结构框图； 图 3是才艮据本发明实施例的频道切换认证方法的流程图； 图 4是根据本发明实施例优选实施例的包括 IPTV频道切换认证装置的 系统的结构框图； 图 5是根据本发明实施例优选实施例的 IPTV频道切换认证的流程图。 具体实施方式 下文中将参考附图并结合实施例来详细说明本发明。 需要说明的是， 在 不冲突的情况下， 本申请中的实施例及实施例中的特征可以相互组合。 本实施例提供了一种频道切换认证装置， 该装置可以连接机顶盒， 也可 以设置在机顶盒的内部， 图 1是根据本发明实施例的频道切换认证装置的结 构框图， 如图 1所示， 该装置包括： 频道切换认证管理模块 （简称为认证管 理模块）， 该认证管理模块包括： 设置单元 12、 接收单元 14、 认证单元 16、 第一发送单元 18 , 下面对此进行详细的说明。 设置单元 12 , 用于为频道列表中的预定频道设置认证信息； 接收单元 14 ,

需要进行切换认证的频道）设置认证信息， 以使用户切换到设置有 认证信息的频道时，发送认证请求，在对用户发送的认证请求认证通过之后， 向用户发送该频道的真实的播放地址， 进而实现了只对特定频道进行认证， 而对于其他频道在频道列表中的播放地址不做处理， 机顶盒可以直接播放这 些频道， 降低了系统的压力。 优选地， 认证管理模块获取用户的认证请求可以通过艮多方式来实现， 例如， 可以向用户提示该频道需要认证， 请用户输入进行认证所需要的信息 (如密码等），或者，也可以由用户预先将认证所需要的信息保存在机顶盒内， 在用户切换到带有认证信息的频道时。 根据本地保存的认证所需要的信息自 动向认证管理模块发送认证请求。 其中， 向用户提示的方式， 实现方便， 但 是， 需要用户进行操作， 而自动发送认证请求需要提前保存与认证相关的信 息， 但是相比于向用户提示的方式避免了用户的操作， 提高了用户的体验。 优选地， 认证管理模块中的设置单元 12 还可以将频道列表中的频道的 地址进行加密， 并将加密后的地址作为认证信息， 在机顶盒切换至地址加密 的频道时， 发送认证请求， 认证管理模块认证通过之后， 发送没有加密的频 道的地址， 使机顶盒根据没有加密的地址进行播放。 优选地， 设置单元 12 还可以 夺认证页面的地址加上频道标识 （即频道 切换认证页面地址 +频道标识） 作为认证信息， 当切换至该频道时， 机顶盒 才艮据认证页面的地址直接跳转到认证页面， 并在该认证页面输入认证相关的 信息（即，该认证页面是用来接收用户的认证请求的）， 然后，该通过该页面， 认证单元 16 获取到认证相关的信息。 为了实现这种提示用户进行认证的方 式，该频道切换认证装置还可以包括一个频道切换认证页面模块， (简称为认 证页面模块） 认证页面模块包括： 页面提供单元 22、 第二发送单元 24 , 下 面对此进行说明。 页面提供单元 22 , 用于向机顶盒提供认证页面， 其中， 认证页面用于接 收机顶盒发送的认证请求； 第二发送单元 24连接至认证单元 16 , 用于将来 自认证页面的认证请求发送给认证管理模块的认证单元。 通过上述认证页面模块提供的认证页面，可以接收用户输入的认证密码， 并于与频道切换认证管理模块交互进行认证， 还可以由认证页面模块获得频 道的真实的播放地址， 触发机顶盒根据该地址进行频道播放。 优选地， 页面提供单元还用于在认证单元认证对认证请求认证失败后， 向机顶盒提供用于提示认证失败的页面。 页面提供单元还用于在认证单元对 认证请求认证失败后提供用于提示重新输入认证信息或切换至其他频道的页 面。 通过上述认证管理模块和认证页面模块， 利用机顶盒的页面跳转功能， 通过增加功能模块实现了频道观看加密功能， 可以实现频道认证、 订购等业 务功能， 同时， 也避免对现有系统关键流程和关键功能模块的改造， 实现方 式简洁高效。 对应于上述的认证管理模块， 还提供了一种频道切换认证方法， 图 3是 根据本发明实施例的频道切换认证方法的流程图， 如图 3所示， 该流程包括 如下步 4聚： 步骤 S302 , 为频道列表中的预定频道设置认证信息； 步骤 S304,接收在用户切换到设置有认证信息的频道时机顶盒发送的认 证请求； 步骤 S306 , 对认证请求进行认证； 步骤 S308, 在认证成功后， 发送播放该频道所需要的信息（例如， 播放 地址）。 例如， 可以直接将该地址发送给机顶盒， 在以下的优选实施例中， 也 可以经由认证页面模块发送给机顶盒。 例如， 将认证页面地址设置为预定频道的认证信息， 其中， 认证页面地 址中携带有该频道的频道标识；在用户切换到设置有认证页面地址的频道时， 向机顶盒提供认证页面地址对应的认证页面， 并通过认证页面用于接收机顶 盒发送的认证请求。 优选地， 在认证失败的情况下， 还可以向机顶盒提供以 下页面的至少之一： 用于提示认证失败的页面、 用于提示重新输入认证信息 的页面、 用于提示切换至其他频道的页面。 优选地， 在接收认证请求之前， 机顶盒可以才艮据本地保存的进行认证所 需要的信息发送认证请求。 优选地， 频道列表中包括有未设置认证标识的频道的频道地址； 在切换 至未设置认证标识的频道时， 机顶盒根据未设置认证标识的频道的频道地址 播放。 下面结合附图对本实施例的优选实施例进行说明。 图 4是才艮据本发明实施例优选实施例的包括 IPTV频道切换认证装置的 系统的结构框图， 如图 4所示， 认证页面模块提供的认证页面 101包括， 用 于接收用户输入认证密码的认证密码输入单元 301、 与频道切换认证管理模 块 （简称为认证管理模块） 102 进行交互完成密码校 -险和实际播放地址获取 的观看认证单元 302 (第二发送单元 24的功能在此单元实现）； 此外， 还可 以包括一个调用机顶盒使用实际播放地址进行频道播放的频道播放单元 303。 频道切换认证管理模块 102 包括： 播放地址加密单元 205 (用于实现设 置单元 12的功能；)， 用于对频道播放列表 103中需要进行切换认证的频道播 放地址进行加密； 频道播放地址解密单元 203 , 用于在进行频道切换认证时， 由频道釆用频道切换认证页面地址和频道标识取代实际的播放地址； 切换认 证信息管理单元 204 , 用于以频道标识为索引保存频道的实际播放地址； 切 换认证密码校验单元 201 (用于实现认证单元 16的功能）， 用于在进行频道 切换认证时， 由根据切换认证管理单元 202中的密码信息对输入的密码进行 校验。 在密码校验成功， 由频道播放地址解密单元 203依据频道标识通过频 道切换认证信息管理单元 204获得实际的播放地址，并返回给认证页面 101。 如图 4所示， 该装置还通过频道播放列表 103与机顶盒进行交互， 该列 表是用户有权限观看的频道播放信息列表， 包括频道标识和播放地址信息， 其中， 需要进行切换认证的频道， 其播放地址已进行加密。 如图 4所示， 该系统还包括一个机顶盒 104 , 支持用户输入认证密码， 才艮据加密的播放地址 （频道切换认证页面地址 +频道编号） 进行页面调转， 并根据获得的实际播放地址进行频道播放。 下面结合图 4对频道切换认证流程进行说明， 图 5是根据本发明实施例 优选实施例的 IPTV频道切换认证的流程图， 该流程包括如下步骤： 步骤 1 , 通过频道切换认证管理模块 102对需要进行切换认证的频道进 行播放地址加密（即， 进行频道观看认证控制）。 例如， 釆用加密的播放地址 (频道切换认证页面地址 +频道标识） 替换该频道的实际播放地址， 并维护 该频道的频道标识和实际播放地址； 步骤 2至步骤 4对此进行了详细说明。 步骤 2, 频道切换认证管理模块 102发起对频道播放列表 103进行频道 切换加密的请求。 步骤 3 , 认证管理模块 102需要进行切换认证的频道釆用频道切换认证 页面地址 +频道标识取代频道播放列表 103中的实际播放地址。 步骤 4, 完成频道播放列表 103的指定频道的播放地址加密， 并向返回 该频道的实际播放地址。 步骤 5 , 频道切换认证管理模块 102以频道标识为索引保存该频道的实 际播放地址。 步骤 6, 用户登录。 步骤 7, 机顶盒 104向频道播放列表 103发起获取用户的频道播放列表 请求。 步骤 8, 频道播放列表 103根据用户权限查询符合条件的频道信息。 步骤 9, 频道播放列表 103向机顶盒 104返回用户的频道播放列表。 步骤 10, 机顶盒 104在本地保存用户的频道播放列表。 步骤 11 , 用户切换到需要进行认证的频道。 步骤 12, 机顶盒 104根据该频道被加密的播放地址， 跳转到频道切换认 证页面 101。 步骤 13 , 频道切换认证页面 101向机顶盒 104返回认证密码输入提示。 此时， 用于用户可以选择不观看该频道， 切换到其他其他频道， 用户也可以 观看该频道， 在用户选择观看此频道的情况下， 进行后续步骤。 步骤 14, 用户输入认证密码。 步骤 15 , 机顶盒 104 4巴认证密码转发给频道切换认证页面 101。 步骤 16, 频道切换认证页面 101根据频道标识和认证密码， 向频道切换 认证管理模块 102发起观看认证请求。 步骤 17, 频道切换认证管理模块 102对用户输入的认证密码进行校验。 步骤 18, 如果密码校验失败， 则返回校验失败， 提示重新输入或切换至 其他频道， 还可以提示校验失败。 步 4聚 19, 密码校-险通过， 频道切换认证管理模块 102 居频道标识， 查 询该频道的实际播放地址。 步骤 20,频道切换认证管理模块 102向频道切换认证页面 101返回实际 播放地址。 步骤 21 ,频道切换认证页面 101釆用实际播放地址调用机顶盒 104进行 频道播放。 步骤 22, 机顶盒 104釆用实际播放地址进行频道播放。 通过本发明的上述实施例， 实现了对于无需进行切换认证的频道直接播 放， 对于需要进行切换认证的频道， 在切换时引导用户进入业务系统进行认 证，认证通过后为用户播放频道，从而在实现对频道切换的认证控制的同时， 降低了业务系统的压力。 显然， 本领域的技术人员应该明白， 上述的本发明的各模块或各步骤可 以用通用的计算装置来实现， 它们可以集中在单个的计算装置上， 或者分布 在多个计算装置所组成的网络上， 可选地， 它们可以用计算装置可执行的程 序代码来实现， 从而， 可以将它们存储在存储装置中由计算装置来执行， 并 且在某些情况下， 可以以不同于此处的顺序执行所示出或描述的步骤， 或者
