Description

频道设置方法、 装置、 设备和计算机存储介庸 技术领域
本发明涉及电通信领域的频道设置技术， 尤其涉及一种频道设置方法、 装置、 设备和计算机存储介质。 背景技术
目前， 在互联网协议电视 ( IPTV， Internet Protocol Television )业务系 统中， 对于频道进行两种形式的混合排序（后续简称混排）： 基于用户侧的 混排 (简称用户频道混排 )和 IPTV业务系统侧的全局频道混排 (简称全局 频道混排）。 混排号码（包括用户频道混排号码和全局频道混排号码）， IPTV 业务系统 对频道的业务操作例如订购、 鉴权等都是基于全局频道混排来进行； 而电 子节目菜单（ EPG， Electronic Program Guide ) 系统向所有用户统一展示的 频道列表中频道的排序则与用户频道混排对应， 目前， 用户无法依据自己 的个人喜好对用户频道混排中的频道次序进行自定义操作。
例如， 某个用户喜欢观看的频道被运营商分配一个频道数量较大的用 户频道混排时， 用户请求播放该节目的操作比较繁瑣： 如果通过直播页面 方式请求播放该频道， 则需要先翻页找到该频道所在的页面， 再请求播放 频道的节目； 如果通过遥控器数字键输入频道号码的方式直接请求该频道 节目， 则需要记住该频道的用户频道混排号码去请求播放。
综上所述， 由于现网 IPTV业务系统侧频道数量多达几百甚至上千， 因 此通过上述方式请求播放频道节目， 对用户来说都显得非常不便， 影响了 用户体验。 发明内容

本发明实施例中， 为用户开通初始的用户频道混排的设置权限， 并根 据用户的设置更新从 EPG系统下载并緩存的业务频道数据； 根据更新后的 緩存的业务频道数据， 为用户侧终端加载用户请求的频道的数据。
下面结合附图及具体实施例对本发明^:进一步详细地说明。
本发明实施例记载了一种频道设置方法， 图 1 为本发明实施例的频道 设置方法的实现流程示意图， 如图 1所示， 所述方法包括以下步骤：
步骤 101 : 从 EPG系统获取并緩存初始的用户频道混排、 全局频道混 排、 所述初始的用户频道混排与所述全局频道混排的对应关系。
本发明实施例中， 初始的用户频道混排为用户订购频道的 （频道以初 始的用户频道混排号码标识） 的排序， 且可以采用列表的形式， 初始的用 户频道混排中的频道按照预设规则分配混排号码， 例如用户订购频道 a、 频 道 b和频道 c时， 可以为上述频道对应分配初始的混排号码 1、 2和 3； 全 局的用户频道混排为 EPG系统侧的所有频道的排序， 相应地， 所有频道对 应分配唯一的全局频道混排号码， 以由 EPG系统根据全局频道混排号码识 别频道， 进行鉴权、 订购等操作， 例如， 假设上述频道 a、 频道 b和频道 c 对应的全局频道混排号码为 4、 5、 6， 则上述对应关系为： 1 |4， 2|5 , 3|6， 其中分隔号 "I" 之前的为用户频道混排号码， 分隔号 "I" 之后的为全局频 道混排号码。
实际应用中， 上述传输流地址可以采用实时传输流协议（RTSP， Real Time Streaming Protocol )地址。
步骤 102: 根据接收到的用户关于用户频道混排的设置信息， 更新緩存 的初始的用户频道混 · 、 以及所述初始的用户频道混 4#与全局频道混排的 对应关系。
实际应用中， 步骤 101中还会从 EPG系统获取童锁混排（可以采用列 表形式）， 即初始的用户频道混排中对儿童限制播放的频道的用户频道混排 号码， 对应地， 本步骤中还会更新童锁用户频道混排。
实际应用中， 从 EPG系统下载的频道业务数据还包括： 频道名称、 频 道的代码（Code, 内容分发网络侧生成的频道标识）、 频道时移长度、 频道 级别等频道业务属性信息。
例如， 对应设置步骤 101中的用户频道混排号码 1、 3的频道对调， 则 更新对应关系为： 3|4， 2|5 , 1 |6； 若童锁混排中包括用户频道混排号码 1， 则更新该童锁混排中的用户频道混排号码 1为 3。
为避免上述对应关系掉电丟失， 优选地， 存储所述更新的用户频道混 排和所述全局频道混排的对应关系至非易失性存储器；
从 EPG系统重新获取并緩存初始的用户频道混排、 全局频道混排、 所 述初始的用户频道混排与所述全局频道混排的对应关系、 以及所述全局频 道混排中的频道对应的传输流地址后， 根据所述存储的对应关系更新所述 緩存的对应关系。
其中， 上述非易失性存储器可以位于 EPG系统侧， 也可以位于緩存所 述对应关系的用户侧设备中， 也可以同时位于 EPG系统侧和用户侧设备； 且当所述对应关系存储至 EPG系统侧的非易失性存储器时， 可以降低用户 侧设备宕机导致对应关系数据丟失的风险， 当用户侧设备恢复后， 可以从 EPG系统侧获取备份的对应关系。
当 EPG系统侧维护的频道发生更新， 例如新增频道或者删除频道时， 该对应关系中仍然保存删除的频道的信息， 并且没有新增频道的信息。 相 应地， 在一个实施方式中， 从 EPG系统重新获取并緩存初始的用户频道混 排与全局频道混排的对应关系后， 确定从 EPG系统重新获取并緩存的全局 频道混排中频道发生更新时， 将所述更新的频道的用户频道混排和全局频 道混排的对应关系， 同步至所述非易失性存储器存储的对应关系。
在上述实施方式中， 从 EPG系统重新获取并緩存初始的用户频道混排 与全局频道混排的对应关系后， 还可以存储从 EPG系统获取并緩存的全局 频道混排至非易失性存储器；
相应地， 所述存储的全局频道混排的混排号码的升序或降序排列字符 串， 与所述从 EPG系统获取并緩存的全局频道混排的混排号码对应的升序 或降序排列字符串不匹配时， 确定所述从 EPG系统获取并緩存的全局频道 混排中的频道发生更新。
其中， 所述确定从 EPG系统重新获取并緩存的全局频道混排中的频道 发生更新， 包括：
从所述存储的对应关系中提取全局频道混排， 所述提取的全局频道混 排的混排号码的升序或降序排列字符串， 与所述从 EPG系统获取并緩存的 全局频道混排的混排号码对应的升序或降序排列字符串不匹配时， 确定所 述从 EPG系统获取并緩存的全局频道混排中的频道发生更新。
例如， 存储的全局频道混排的混排号码的升序排列字符串， 或者， 从 存储的对应关系中提取全局频道混排的混排号码的升序排列字符串， 设为 1、 3、 5， 当 EPG系统侧的频道发生更新， 例如增加频道 9 ( 9为该增加频 道在 EPG系统侧的全局频道混排号码 )， 则 EPG系统侧的混排号码的升序 排列字符串为 1、 3、 5、 9， 与字符串 1、 3、 5不匹配， 表示 EPG系统侧的 全局频道混排发生更新， 则将全局频道混排号码 9存储至非易失性存储器， 或者， 根据频道 9 的全局频道混排号码和初始的用户频道混排号码的对应 关系， 更新非易失性存储器中存储用户频道混排和全局频道混排的对应关 系。
在一个实施方式中， 还从所述全局频道混排中的频道对应的传输流地 址； 相应地， 当接收用户请求的频道的用户频道混排号码时， 根据所述更 新后的緩存的用户频道混排、 所述全局频道混排以及所述用户频道混排和 所述全局频道混排的对应关系， 确定所述用户频道混排号码对应的全局频 道混排号码； 根据所述确定的全局频道混排号码、 以及緩存的所述全局频 道混排中的频道对应的传输流地址， 确定所述用户请求的频道的传输流地 址， 并为用户终端加载所述传输流地址对应的数据。
例如， 初始的用户频道混排号码为 5 (设该频道的全局频道混排号码为 7 ) 的频道， 初始的用户频道混排号码为 1 (设该频道的全局频道混排号码 为 9 ) 的频道的相应的对应关系为 5|7， 1 |9， 则当用户将初始的用户频道混 排号码为 5的频道与初始的用户频道混排号码为 1 的频道对调后， 更新后 的对应关系为： 5|9， 1 |7。
例如， 当用户请求用户频道混排号码为 5 的频道时， 根据更新后的对 应关系 （上述 5|9， 1 |7 )确定该频道对应的全局频道混排号码为 7， 以该混 排号码 7为索引查询该频道对应的传输流地址。
本发明实施例所提供的技术方案中， 接收用户关于用户频道混排的设 置信息， 根据所述设置信息更新緩存的初始的用户频道混排、 以及所述初 始的用户频道混排与全局频道混排的对应关系， 从而， 能够根据上述更新 的用户频道混排、 以及用户频道混排与全局频道混排的对应关系响应用户 播放指定混排号码对应频道的请求， 解决了用户请求频道节目时操作繁瑣 的问题； 并且， 解决了现有用户侧的用户频道混排不能由用户进行设置的 问题， 用户可以对自己喜欢的频道按喜好进行排序， 方便了用户的个人使 用习惯， 提高 IPTV系统频道直播业务的交互性， 实现了用户对频道设置的 主导权和控制权， 进一步增强了用户体验
本发明实施例还记载一种频道设置装置， 图 2 为本发明实施例的频道 设置的组成结构示意图， 如图 2所示， 所述装置包括： 获取模块 21、 更新 模块 23和緩存模块 22; 其中，
所述获取模块 21，配置为从 EPG系统获取并存储初始的用户频道混排、 全局频道混排、 所述初始的用户频道混排与所述全局频道混排的对应关系 至所述緩存模块 22;
所述更新模块 23， 配置为根据接收到的用户输入的频道设置信息， 对 緩存模块 22存储的初始的用户频道混排进行更新、 并对所述緩存模块 22 存储的所述初始的用户频道混排与全局频道混排的对应关系进行更新。
优选地，

优选地， 所述存取模块 26， 还配置为存储从 EPG系统获取并緩存的全 局频道混排至非易失性存储器；
所述确定模块 24， 还配置为在所述非易失性存储器存储的全局频道混 排的混排号码的升序或降序排列字符串， 与所述緩存模块 22緩存的全局频 道混排的混排号码对应的升序或降序排列字符串不匹配时， 确定所述緩存 的全局频道混排中的频道发生更新。
优选地， 所述确定模块 24， 还配置为在从所述非易失性存储器存储的 对应关系中提取全局频道混排， 并所述提取的全局频道混排的混排号码的 升序或降序排列字符串， 与所述緩存模块 22存储的全局频道混排的混排号 码对应的升序或降序排列字符串不匹配时， 确定所述緩存模块 22存储的全 局频道混排中的频道发生更新。
实际应用中， 所述获取模块 21、 所述更新模块 23、 所述确定模块 24 和所述加载模块 25 可由频道设置装置中的中央处理器 （CPU， Central Processing Unit ), 数字信号处理器（DSP， Digital Signal Processor )或现场 可编程门阵列 （FPGA， Field Programmable Gate Array ) 实现； 所述緩存模 块 22可由频道设置装置中易失性存储介质实现； 所述存取模块 26可由频 道设置装置中的非易失性存储介质实现。
本发明实施例还记载一种频道设置设备， 包括前述的频道设置装置， 该频道设置设备可以替代相关技术机顶盒（STB， Set Top Box )使用。
实际应用中， 本发明实施例所提供的频道设置装置可以模块的形式嵌 入在 IPTV业务 STB中， STB不受型号、 规格及生产厂商的限制。
需要说明的是， 后续实施例中以设置上述频道设置装置的机顶盒为例， 对本发明进行说明， 但不构成对本发明的不当限定。
图 3为本发明实施例中频道设置的实现流程示意图一， 如图 3所示， 包括以下步骤：
步骤 301 : EPG系统将频道业务数据下发到机顶盒。
其中， 频道业务数据包括： 初始的用户频道混排、 全局频道混排、 所 述初始的用户频道混排与所述全局频道混排的对应关系以及所述全局频道 混排中的频道对应的传输流地址。
其中， 机顶盒在本地緩存中保存将该频道业务数据， 供机顶盒的浏览 器模块调用。
该步骤为机顶盒开机登录 IPTV业务系统时的默认操作。
步骤 302 ~步骤 303: 终端通过设置页面接收用户对当前用户频道混排 的自定义设置信息， 并将该设置信息发送至机顶盒。
终端调用机顶盒开放的自定义接口， 实现用户对机顶盒緩存的初始用 户频道混排的设置。
步骤 304: 机顶盒利用接收的设置信息更新本地緩存的频道业务数据。 例如， 利用接收的设置信息， 更新初始的用户频道混排、 所述初始的 用户频道混排与所述全局频道混排的对应关系。
步骤 305: 机顶盒将所述对应关系存储至本地非易失性存储器， 和 /或 EPG系统非易失性存储器。
其中， 机顶盒的非易失性存储器可以采用闪存（Flash Memory ), 保证 机顶盒断电重启后存储的对应关系数据不丟失。
本步骤中，机顶盒通过 EPG系统开放的接口上传对应关系至 EPG系统 存储。
步骤 305之后为机顶盒断电重启后的处理。
步骤 306: 机顶盒读取本地非易失性存储器和 /或 EPG系统非易失性存 储器中存储的对应关系至緩存。
步骤 307: 机顶盒从 EPG系统重新下载频道业务数据。
相应地， 机顶盒緩存该频道业务数据。
其中， 步骤 306和步骤 307的执行顺序可以对调。
步骤 308: 机顶盒利用读取的对应关系更新緩存的频道业务数据。
例如，利用读取的对应关系更新 EPG系统下发的初始的用户频道混 4非、 以及初始的用户频道混 和全局频道混 的对应关系；
若步骤 305之后机顶盒宕机导致本地非易失性存储器的对应关系数据 丟失， 且步骤 304中对应关系同时存储至本地和 EPG系统的非易失性存储 器， 则本步骤中通过 EPG系统开放的接口获取步骤 304上传备份的对应关 系， 并利用该对应关系更新緩存的 EPG系统下发的初始的用户频道混排、 以及初始的用户频道混 和全局频道混 的对应关系。
图 4为本发明实施例中频道设置的实现流程示意图二， 如图 4所示， 包括以下步骤：
步骤 401 ~步骤 402: 终端接收用户对某个频道的用户频道混排号码的 设置信息， 并将该设置信息发送至机顶盒。 终端通过调用 EPG系统开放的接口， 向用户展示用户频道混排的设置 页面， 并接收用户的设置。
步骤 403:机顶盒判断用户设置的混排号码进行合法性校验，如果合法， 则执行步骤 404; 否则转入步骤 407， 向终端返回混排号码校验失败的设置 结果。
合法性校验是指判断用户设定的用户频道混排号码是否在用户频道混 排对应的混排数组当中， 比如当前用户可见的频道的混排号码为 1、 2、 3 (假如 1订购， 2和 3未订购）， 用户将 1频道的混排号码从 1设置为 4， 即 1频道和 4频道对调， 由于 4频道的混排号码 4不在用户频道混排对应 的混排数组（1、 2、 3 ) 中， 则不允许用户进行上述设置。
步骤 404:机顶盒机顶盒利用接收的设置信息更新本地緩存的频道业务 数据。
例如， 利用接收的设置信息， 更新初始的用户频道混排、 初始的用户 频道混排与全局频道混排的对应关系； 相应地， 如果机顶盒还获取到童锁 混排列表形式， 则对应更新童锁混排。
步骤 405:机顶盒将所述更新后的緩存的对应关系存储至本地非易失性 存储器。
机顶盒还可以将步骤 404更新后的对应关系存储至 EPG系统非易失性 存储器。
其中， 机顶盒的非易失性存储器可以采用闪存， 保证机顶盒断电重启 后存储的对应关系数据不丟失； 机顶盒通过 EPG系统开放的接口上传对应 关系至 EPG系统存储。
步骤 406: 机顶盒将自定义混排标志位置 1。
标识位置 1表示步骤 404所述的非易失性存储器的至少之一存储有用 户频道混排和全局用户频道混排的对应关系。 步骤 407: 机顶盒返回自定义混排设置结果给终端。
步骤 408: 终端向用户展示用户设置结果。
例如， 用户设置的用户频道混排号码校验失败时， 提示校验失败； 机 顶盒返回自定义混排设置结果时， 向用户展示设置结果。
图 5为本发明实施例中频道设置的实现流程示意图三， 如图 5所示， 包括以下步骤：
步骤 501： EPG系统加载频道业务数据。
其中， 频道业务数据包括： 初始的用户频道混排、 全局频道混排、 初 始的用户频道混排与全局频道混排的对应关系以及全局频道混排中的频道 对应的传输流地址。
步骤 502: 机顶盒从 EPG获取系统频道业务数据。
相应地， 机顶盒緩存获取的频道业务数据。
机顶盒通过内置的浏览器模块获取频道业务数据到本地 JavaScript对 象， 以緩存频道业务数据。
步骤 503: 机顶盒读取本地自定义混排标志位， 如标志位为 1， 则执行 步骤 504， 否则停止处理。
步骤 504:机顶盒读取非易失性存储器中的用户频道混排和全局用户频 道混排的对应关系， 利用读取的对应关系更新緩存的频道业务数据。
所述非易失性存储器位于机顶盒本地和 /或位于 EPG系统。
例如， 机顶盒从本地非易失性存储器或 EPG系统非易失性存储器中读 取对应关系， 更新步骤 502緩存的用户频道混排、 用户频道混排与全局频 道混排的对应关系； 相应地， 如果步骤 502 中机顶盒还获取童锁混排， 则 更新该童锁混排。
步骤 505: 机顶盒判断 EPG系统侧的全局用户频道混排中的频道是否 发生更新， 如果更新， 则执行步骤 506; 否则， 停止处理。 本步骤中， 判断 EPG系统侧的全局频道混排中的频道是否发生更新， 可以通过步骤 5051至步骤 5054实现：
步骤 5051 : 机顶盒解析非易失性存储器的对应关系， 提取出该对应关 系中的频道的全局频道混排号码， 生成对应的全局频道混排数组。
步骤 5052:将全局频道混排数组转化为按照升序或降序排序的字符串。 步骤 5053: 解析步骤 502获取并緩存的全局频道混排， 转化为字符串。 该字符串的排序与步骤 5052的排序相同， 即同时采用升序或同时采用 降序排列。
步骤 5054: 判断步骤 5052与 5053的字符串是否匹配， 如果匹配， 则 判定发生更新，标识 EPG系统侧的全局频道混排中的频道发生更新； 否贝 J , 判定未发生更新。
步骤 506:机顶盒利用发生更新频道的对应关系更新非易失性存储器存 储的对应关系。
如果 EPG系统侧全局频道混排中的频道增加，则机顶盒将 EPG系统侧 为该频道预设的初始的用户频道混排和全局频道混排的对应关系存储至非 易失性存储器； 如果 EPG系统侧全局频道混排中的频道删除， 则将非易失 性存储器中存储的该删除频道的对应关系删除。
步骤 506中， 机顶盒也可以将非易失性存储器存储器存储的对应关系， 更新为步骤 504 中更新后的緩存的对应关系， 以将发生更新频道对应关系 同步至非易失性存储器。
步骤 507: 机顶盒返回更新后的用户频道混排至终端。
步骤 508: 终端展示用户频道混排信息。
图 6为本发明实施例中频道设置的实现流程示意图四， 如图 6所示， 包括以下步骤：
步骤 601 : 机顶盒登陆 EPG系统时， EPG系统将频道业务数据下发到 机顶盒。
步骤 602: 终端向机顶盒发送用户频道混排的设置信息。
步骤 603: 机顶盒存储当前的用户频道混排、用户频道混排和全局频道 混排的对应关系至非易失性存储器。
所述非易失性存储器位于机顶盒本地和 /或位于 EPG系统。
相应地， 如果 EPG系统还下发童锁混排， 则同时备份该童锁混排。 后续步骤机顶盒根据用户设置信息更新频道业务数据的操作与以上所 述相同。
步骤 604: 终端向机顶盒发送用户频道混排的重置信息。
终端通过调用机顶盒的重置接口触发机顶盒进行重置操作。
步骤 605: 机顶盒将步骤 603存储的用户频道混排、用户频道混排和全 局频道混排的对应关系替换当前的緩存的用户频道混排、 用户频道混排和 全局频道混排的对应关系。
相应地， 如果步骤 603还存储了童锁混排， 则将当前的童锁混排替换 为步骤 603存储的童锁混排。
步骤 606: 机顶盒将自定义混排标志位置 0。
标识位置 0标识用户没有对用户频道混排进行设置。
步骤 607: 机顶盒清空非易失性存储器存储的对应关系。
步骤 608: 机顶盒返回用户频道混排重置结果给终端。
步骤 609: 终端显示用户频道混排重置成功。
