  • the service key is usually divided into two modes: In the PULL mode, if there is no service key when the user plays, the service key is acquired and stored by interacting with the information of the network platform and the card; In the mode, when the network platform pushes the service key, the terminal is used to trigger the terminal to perform the service key acquisition process.
  • the current service key update mechanism is a combination of network active push and client/terminal request acquisition. There are three ways for the client/terminal to obtain the service key:
  • the client/terminal obtains the service key during the ordering process: When the user subscribes to a channel/program, the network platform authenticates the user in the ordering process. If the authentication succeeds, the service key is sent to the client/terminal in the subscription response message, and the client/client forwards the authentication key to the user authentication module.
  • the client/terminal When the client/terminal discovers that there is no service key locally, the client/terminal will actively obtain the service key from the platform: The client/terminal determines whether the local service key is saved or not. If the local service is not saved, the valid service key is not saved. The key, the client/terminal queries the subscription relationship table to determine whether the user has subscribed to the service. If ordered, initiates the process of initiating a service key request to the network.
  • the client/terminal also supports requesting multiple service keys in one message.
  • Active push mode of the service platform After the user subscribes to a certain channel/program, the platform will notify the user through the PUSH message at the appropriate time, triggering the terminal to start the service key acquisition process. From the perspective of the user, the user does not frequently perform the operations related to order unsubscribing, and the probability of obtaining the service key during the ordering process is not high. Moreover, for data cards, netbooks, etc., the average power is re-powered at least once a day. If the power is turned on again, the previously saved service key will be invalid. For the mobile terminal, once the computer is turned off and then turned on, the service key will become invalid. .

Abstract

本发明公开了一种终端及其电视业务的播放方法，其中，该方法包括：终端向业务平台获取业务密钥；终端接受用户对节目的选择；终端使用获取到的业务密钥播放用户选择的节目。本发明保证了用户选择节目进行播放时本地已经保存有有效的业务密钥，加快了播放加密节目的响应速率，增强了用户体验。

Description

终端及其电视业务的番放方法 技术领域 本发明涉及通信领域， 尤其涉及一种终端及其电视业务的播放方法。 背景技术 在通信技术中， 对于传输的信息进行保密已经成为客户越来越正常的需 求， 在通信技术中进行加密的主要目的在于帮助保护用户的标识或数据不被 读取， 帮助保护数据不被更改， 以及确保数据发自特定的一方。 归纳而言， 即要满足保密性， 数据完整性， 和身份验证的需求。 在手机电视业务中， 业务密钥是用于对节目密钥进行加密的密钥。 业务 密钥的获取通常分为两种模式： 在 PULL模式下， 若在用户播放时没有业务 密钥， 则通过与网络平台和卡的信息交互， 实现业务密钥的获取和存储； 而 在 PUSH模式下， 在网络平台推送业务密钥时， 通过短信通知方式触发终端 进行业务密钥获取流程。 目前的业务密钥更新机制是釆用网络主动推送和客户端 /终端请求获取 相结合的方式。 其中， 客户端 /终端获取业务密钥的方式有三种：
( 1 )客户端 /终端在订购过程中获取业务密钥： 当用户订购某个频道 /节 目后， 网络平台会在订购流程中对用户进行鉴权。 如果鉴权成功， 则在订购 响应消息中将业务密钥发送给客户端 /终端， 客户端 /客户端再转发给用户认 证模块。 ( 2 ) 客户端 /终端在播放节目时发现本地没有业务密钥， 会主动向平台 获取业务密钥： 客户端 /终端判断本地是否保存有有效的业务密钥， 如果本地 未保存有效的业务密钥， 则客户端 /终端查询订购关系表判断用户是否订购了 该业务。 如果已订购， 则启动向网络发起业务密钥请求的流程。 另外， 客户 端 /终端还支持在一条消息中请求多个业务密钥。 ( 3 ) 业务平台主动推送方式： 在用户订购某个频道 /节目以后， 平台会 在适当的时候通过 PUSH消息通知用户， 触发终端启动业务密钥获取流程。 从用户角度考虑， 用户不会频繁进行订购退订的相关操作， 在订购过程 中获取业务密钥的机率不高。 况且， 对于数据卡、 上网本等， 平均每天最少 重上电一次， 重上电会使之前保存的业务密钥无效， 对于手机终端， 关机一 次再开机进入手机电视， 业务密钥也会变得无效。 每次进入业务为了获取业 务密钥先退订， 再订购是不可能的。 因此， 大多数情况下， 在实际应用时客 户端 /终端主要是在播放节目时主动向平台发起获取业务密钥的流程。 图 1为才艮据相关技术的终端播放加密节目的流程图， 包括以下步骤： 步骤 S 102,终端响应于用户选择进入手机电视业务的操作指令启动电视 业务， 并进行电视业务的初始化； 步骤 S 104, 终端接受用户选择节目进行播放； 步骤 S 106, 终端会先判断本地是否保存有有效的业务密钥。 若有业务密 钥则执行步骤 S 114, 若没有有效的业务密钥， 则执行步骤 S 106; 步 4聚 S 108, 终端进入业务密钥的获取流程； 步骤 S 110, 经过一段时间的鉴权交互后判断获取业务密钥是否成功， 若 是， 则转入步骤 S 114, 若否， 则转入步骤 S 112; 步骤 S 112, 终端给出相关提示； 以及 步骤 S 114 , 终端直接进行播放。 才艮据上述流程， 步 4聚 S 106判断为有业务密钥直接执行步 4聚 S 114, 其所 需的时间大致为 1.5秒左右， 和进入播放未加密的节目花费时间一样； 而步 骤 S 106判断为没有有效的业务密钥到执行步骤 S 114进行播放， 所需要花费 的时间平均为 10秒左右， 与之前的 1.5秒相比所需时间明显增加。 因此， 在相关技术中由于获取业务密钥的流程是位于用户选择播放节目 与开始播放之间， 从而会导致进入播放的时间加长， 影响用户体验。 另外， 还需要考虑对于免费的频道的处理， 平台会对开通了业务的终端 主动下发业务密钥 ,此业务密钥的下发是随着订购关系表的下发一起进行的。 若平台下发业务密钥失败（业务密钥没有下发下来）， 此时， 终端还是需要在 播放该免费节目时向平台获取业务密钥， 因此同样存在上述问题。 发明内容 本发明的主要目的在于提供一种终端及其电视业务的播放方法， 以至少 解决上述问题。 根据本发明的一个方面，提供了一种终端的电视业务的播放方法， 包括： 终端向业务平台获取业务密钥； 终端接受用户对节目的选择； 终端使用获取 到的业务密钥播放用户选择的节目。 优选地， 终端向业务平台获取业务密钥包括： 终端启动电视业务， 并在 启动过程中获取业务密钥。 优选地， 终端向业务平台获取业务密钥是在终端启动电视业务之前。 优选地， 终端向业务平台获取业务密钥包括： 终端向业务平台获取用户 的订购关系， 其中订购关系包括业务密钥标识与业务密钥的对应关系； 终端 使用订购关系中的业务密钥标识向业务平台获取业务密钥标识所对应的业务 密钥； 终端将获取到的业务密钥保存到本地。 优选地， 终端使用订购关系中的业务密钥标识向业务平台获取业务密钥 标识所对应的业务密钥包括： 终端向业务平台发送业务密钥获取请求消息， 其中， 业务密钥获取请求消息中包含多个电视节目套餐和 /或免费电视节目的 业务密钥标识； 终端接收业务平台返回的多个电视节目套餐和 /或免费电视节 目的业务密钥标识所对应的多个电视节目套餐和 /或免费电视节目的业务密 钥。 优选地，在终端将获取到的业务密钥保存到本地之后， 上述方法还包括： 对于获取到的业务密钥中具有业务平台所标记的确认标记的业务密钥， 终端 向业务平台进行确认。 根据本发明的另一方面， 提供了一种终端， 包括： 业务密钥获取模块， 用于向业务平台获取业务密钥； 接受模块， 用于接受用户对节目的选择； 播 放模块， 用于使用获取到的业务密钥播放用户选择的节目。 优选地， 在上述的终端中， 还包括： 启动模块， 用于启动电视业务； 其 中， 业务密钥获取模块在启动模块启动电视业务的过程中获取业务密钥， 或 者在向业务平台获取业务密钥是在启动模块启动电视业务之前。 优选地， 业务密钥获取模块包括： 第一获取单元， 用于向业务平台获取 用户的订购关系， 其中订购关系包括业务密钥标识与业务密钥的对应关系； 第二获取单元， 用于使用订购关系中的业务密钥标识向业务平台获取业务密 钥标识所对应的业务密钥； 保存单元， 用于将获取到的业务密钥保存到本地。 优选地， 第二获取单元包括： 发送子单元， 用于向业务平台发送业务密 钥获取请求消息， 其中， 业务密钥获取请求消息中包含多个电视节目套餐和 / 或免费电视节目的业务密钥标识； 接收子单元， 用于接收业务平台返回的多 个电视节目套餐和 /或免费电视节目的业务密钥标识所对应的多个电视节目 套餐和 /或免费电视节目的业务密钥。 通过本发明， 由于在终端接受用户对节目的选择播放节目之前预先获取 业务密钥， 解决了现有技术中进入播放的时间较长的问题， 从而保证了用户 选择节目进行播放时本地已经保存有有效的业务密钥， 加快了播放加密节目 的响应速率， 增强了用户体 -险。 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为根据相关技术的终端播放加密节目的流程图； 图 2示出了才艮据本发明实施例的终端的示意图； 图 3示出了才艮据本发明实施例的业务密钥获取模块的示意图； 图 4为根据本发明实施例的终端的电视业务的播放方法的流程图； 图 5为根据本发明优选实施例一的电视业务的具体播放流程图； 图 6为根据本发明优选实施例二的电视业务的具体播放流程图。 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。 图 2示出了才艮据本发明实施例的终端的示意图， 包括： 业务密钥获取模块 20 , 用于向业务平台获取业务密钥； 接受模块 30 , 用于接受用户对节目的选择； 播放模块 40 , 用于使用获取到的业务密钥播放用户选择的节目。 该实施例由于在终端接受用户对节目的选择播放节目之前预先获取业务 密钥， 解决了现有技术中进入播放的时间较长的问题， 从而保证了用户选择 节目进行播放时本地已经保存有有效的业务密钥， 加快了播放加密节目的响 应速率， 增强了用户体验。 优选地， 在上述的终端中， 还包括： 启动模块 10 , 用于启动电视业务； 其中， 业务密钥获取模块 20在启动模块 10启动电视业务的过程中获取 业务密钥。 该优选实施例的终端由于 4巴业务密钥的获取置前， 将获取业务密钥的步 骤放在电视业务的启动 （即初始化） 过程中， 解决了相关技术中进入播放的 时间较长的问题， 从而保证了播放时本地已经保存有有效的业务密钥， 加快 了播放加密节目的响应速率， 增强了用户体 -险。 或者， 优选地， 在上述的终端中， 还包括： 启动模块 10 , 用于启动电视业务。 其中， 业务密钥获取模块 20向业务平台获取业务密钥是在启动模块 10 启动电视业务之前。 该优选实施例的终端由于 4巴业务密钥的获取置前， 将获取业务密钥的步 骤放在启动电视业务之前， 解决了相关技术中进入播放的时间较长的问题， 从而保证了用户选择节目进行播放时本地已经保存有有效的业务密钥， 加快 了播放加密节目的响应速率， 增强了用户体验。 其中， 如图 3所示， 在上述的优选实施例中， 业务密钥获取模块 20 包 括： 第一获取单元 201 , 用于向业务平台获取用户的订购关系， 其中订购关 系包括业务密钥标识与业务密钥的对应关系； 第二获取单元 202 , 用于使用订购关系中的业务密钥标识向业务平台获 取业务密钥标识所对应的业务密钥； 保存单元 203 , 用于将获取到的业务密钥保存到本地。 该优选实施例提供了业务密钥获取模块在电视业务的初始化过程中， 终 端获取业务密钥的具体实施方案。 终端通过与业务平台的交互更新订购关系 表， 从而可以根据更新的订购关系表中的各电视节目套餐或各频道的电视节 目 （包括免费电视节目 ） 的业务密钥标识来获取到这些用户订购的以及免费 的电视节目的业务密钥。 其中， 第二获取单元 202包括： 发送子单元 2021 , 用于向业务平台发送业务密钥获取请求消息， 其中， 业务密钥获取请求消息中包含多个电视节目套餐和 /或免费电视节目的业务 密钥标识； 接收子单元 2022 , 用于接收业务平台返回的多个电视节目套餐和 /或免 费电视节目的业务密钥标识所对应的多个电视节目套餐和 /或免费电视节目 的业务密钥。 与相关技术中只能一次获取单个电视节目套餐或单个频道相比， 该优选 实施例中的业务密钥获取模块由于将业务密钥的获取步骤置前， 即预先获取 业务密钥， 可以同时把多个电视节目套餐 (包括免费频道）放在一条业务密 钥获取请求消息中一起进行请求， 因此终端能够一次同时获取到多个电视节 目套餐的业务密钥。 上述的终端可以是数据卡或上网笔记本电脑等， 也可以是移动终端， 如 手机等。 图 4示出了根据本发明实施例的终端的电视业务的播放方法， 包括以下 步骤： 步骤 S402, 终端向业务平台获取业务密钥； 步骤 S404, 终端接受用户对节目的选择;
