图 1为本发明实施例的节目信息交流方法流程示意图一；
图 2为本发明实施例的节目信息交流方法流程示意图二；
图 3为本发明实施例的节目信息交流设备结构示意图一；
图 4为本发明实施例的节目信息交流设备结构示意图二；
图 5为本发明实施例的节目信息交流设备结构示意图三；
图 6为本发明实施例的通信系统结构示意图。 具体实施方式 以下描述中， 为了说明而不是为了限定， 提出了诸如特定系统结构、 接口、 技术之类的具体细节， 以便透切理解本发明。 然而， 本领域的技术人员应当清 楚， 在没有这些具体细节的其它实施例中也可以实现本发明。 在其它情况中， 省略对众所周知的装置、 电路以及方法的详细说明， 以免不必要的细节妨碍本 发明的描述。
用户设备， 可以是无线终端也可以是有线终端， 无线终端可以是指向用户 提供语音和 /或数据连通性的设备， 具有无线连接功能的手持式设备、 或连接到 无线调制解调器的其他处理设备。无线终端可以经无线接入网（例如， RAN, Radio Access Network ) 与一个或多个核心网进行通信， 无线终端可以是移动终端， 如移动电话 （或称为 "蜂窝" 电话） 和具有移动终端的计算机， 例如， 可以是 便携式、 袖珍式、 手持式、 计算机内置的或者车载的移动装置， 它们与无线接 入网交换语言和 /或数据。 例如， 个人通信业务 (PCS, Personal Communication Service) 电话、 无绳电话、 会话发起协议 （SIP) 话机、 无线本地环路 （WLL， Wireless Local Loop) 站、 个人数字助理 (PDA, Personal Digital Assistant) 等设备。 无线终端也可以称为系统、 订户单元 （Subscriber Unit) 、 订户站 (Subscriber Station) ， 移动站 (Mobile Station) 、 移动台 (Mobile) 、 远程站 ( Remote Station) 、 接入点 (Access Point) 、 远程终端 ( Remote Terminal ) 、 接入终端 ( Access Terminal ) 、 用户终端 ( User Terminal ) 、 用户代理 （User Agent) 、 用户设备 （User Device) 、 或用户装备 （User Equipment ) 。
本发明实施例提供一种节目信息交流方法， 如图 1所示， 该方法包括：
5101、 节目信息交流设备获取节目评论指令。
示例性的， 节目信息交流设备获取节目评论指令的方式可以为节目信息交流设 备接收用户通过遥控器等控制设备输入的节目评论指令。
用户在观看电视节目时， 若想对当前节目进行评论， 或想知道其他人对当前节目 的评论是什么， 可以通过遥控器等控制设备输入节目评论指令， 例如， 遥控器上可以 设置节目评论按钮， 用户仅需点击该节目评论按钮， 便可发出节目评论指令， 以触发 节目交流设备在预先建立的数据库中提取当前节目的信息。
5102、 节目信息交流设备根据节目评论指令从预先建立的数据库中提取当前节 目的信息。
这里， 需要对预先建立的数据库进行说明： 预先建立的数据库可以存储在服务器 端， 例如广电网络终端， 服务器将节目的音视频流与有关节目的信息， 如节目名称、 剧集、 评论地址、 服务器地址等打包在一起并通过有线或无线的方式进行广播， 本发 明实施例提出的打包， 是指将压缩后的文件进行数据分组， 以满足信号传输的需求。
那么， 节目信息交流设备在获取节目评论指令后， 会从预先建立的数据库中提取 出当前节目的信息， 该信息中可能包括节目名称、 剧集、 评论地址、 服务器地址等。
5103、 若信息中包括节目评论地址， 节目信息交流设备则将节目评论地址发送 至用户设备， 以使得用户根据节目评论地址获知当前节目的评论或对当前节目进行评 论。
节目信息交流设备在将当前节目的信息提取出来后， 会判断该信息中是否 包括节目评论地址， 若该信息中包括节目评论地址， 那么节目信息交流设备会 将节目评论地址发送至用户设备， 例如， 可以通过无线路由器发送至用户设备。 用户设备在接收到来自节目信息交流设备的节目评论地址后， 可以根据节目评 论地址连接到相关网页， 那么使用该用户设备的用户， 便可获知当前节目的评 论， 也可以通过用户设备对当前节目进行评论。
需要补充的是， 节目信息交流设备并不会对所有的用户设备都发送节目评 论地址， 节目信息交流设备会与用户设备进行权限验证， 那么就只与通过权限 认证的用户设备通信， 例如， 节目信息交流设备可以在设备开启时与用户设备 进行一次权限验证、 建立连接， 进而将节目评论地址发送至该用户设备。
S 104、 若信息中不包括节目评论地址， 节目信息交流设备则将信息中的服务器 地址发送至用户设备， 以使得用户设备根据服务器地址与服务器建立连接， 进而使得 用户通过用户设备对当前节目进行评论。
节目信息交流设备在将当前节目的信息提取出来后， 会判断该信息中是否 包括节目评论地址， 若该信息中不包括节目地址， 那么节目信息交流设备会将 该信息中的服务器地址发送至用户设备， 同样的， 可以通过无线路由器发送至 用户设备。 用户设备在接收到来自节目信息交流设备的服务器地址后， 可以根 据服务器地址连接到服务器， 进而， 服务器会为用户设备创建该节目的评论社 区， 那么使用该用户设备的用户， 便可通过用户设备对当前节目进行评论， 进 一步地， 服务器将新建立的节目评论地址存储在该节目的信息中， 并存储在预 先建立的数据库中。
需要说明的是， 在本发明实施例中， 步骤 S 103与步骤 S 104并没有先后的 顺序， 步骤 S 103所描述的是当信息中包括节目评论地址时的情况， 步骤 S 104 所描述的是当信息中不包括节目评论地址时的情况， 因此并没有时间顺序的限 定。
本发明实施例提供的节目信息交流方法， 通过在获取节目评论指令后， 根 据节目评论指令从预先建立的数据库中提取当前节目的信息， 若该信息中包括 节目评论地址， 则将节目评论地址发送至用户设备， 以使得用户根据节目评论 地址获知当前节目的评论或对当前节目进行评论， 若该信息中不包括节目评论 地址， 则将该信息中的服务器地址发送至用户设备， 以使得用户设备根据服务 器地址与服务器建立连接， 进而使得用户通过用户设备对当前节目进行评论。 通过该方案， 能够使得用户通过用户设备对当前观看的节目进行评论， 并且不 增加外接输入设备。
本发明实施例提供一种节目信息交流方法， 如图 2所示， 该方法包括： S201、 节目信息交流设备与用户设备进行权限认证， 只与通过权限认证的 用户设备通信。
示例性的，节目信息交流设备可以在设备开启时与用户设备进行权限验证、 建立连接， 那么就只与通过权限认证的用户设备通信。
需要说明的是， 本发明实施例将节目信息交流设备与用户设备进行权限认 证设置为节目信息交流方法的第一步仅是一个优选方案， 即目信息交流设备在 开启时与用户设备只进行一次权限验证、 建立连接是一个优选方案， 但具体地 实施方式并不限制于此， 还可以在信息交流设备需要向用户设备发送信息是进 行权限验证， 本发明实施例不做限制。
S202、 节目信息交流设备获取节目指令， 节目指令用于指示用户需要观看 的节目。
示例性的， 节目信息交流设备获取节目指令的方式可以为节目信息交流设备接 收用户通过遥控器等控制设备输入的节目指令， 该节目指令用于指示用户想要观看哪 些节目。
S203、 节目信息交流设备根据节目指令从预先建立的数据库中提取相应的 节目音视频流。
节目信息交流设备在获取节目指令后， 会从预先建立的数据库中提取相应 的节目音视频流， 在上一实施例已经指出， 服务器将节目的音视频流与有关节 目的信息， 如节目名称、 剧集、 评论地址、 服务器地址等打包在一起并通过有 线或无线的方式进行广播， 那么， 节目信息交流设备便可以提取出相应的节目 音视频流。
5204、 节目信息交流设备对音视频流进行解扰解码。
由于服务器在将节目的音视频流与有关节目的信息打包时会对打包后的文 件进行加扰编码， 即预先建立的数据库为服务器将节目的信息和节目音视频流 加扰编码后所形成的节目流， 例如， 某些需要付费的节目需要通过解扰解码后 才能够观看， 那么， 节目信息交流设备会对提取出的音视频流进行解扰解码。
5205、 节目信息交流设备输出解扰解码后的音视频流。
节目信息交流设备对音视频流进行解扰解码后， 会输出解扰解码后的音视 频流， 具体地， 可以输出至显示设备， 例如， 电视机， 用户便能够通过显示设 备观看节目了。 5206、 节目信息交流设备获取节目评论指令。
用户在观看电视节目时， 若想对当前节目进行评论， 或想知道其他人对当前节目 的评论是什么， 可以通过遥控器等控制设备输入节目评论指令， 例如， 遥控器上可以 设置节目评论按钮， 用户仅需点击该节目评论按钮， 便可发出节目评论指令， 以触发 节目交流设备在预先建立的数据库中提取当前节目的信息。
5207、 节目信息交流设备根据节目评论指令从预先建立的数据库中提取当 前节目的信息。
节目信息交流设备在获取节目评论指令后， 会从预先建立的数据库中提取出当前 节目的信息， 该信息中可能包括节目名称、 剧集、 评论地址、 服务器地址等。
S208、 若信息中包括节目评论地址， 节目信息交流设备则将节目评论地址 发送至用户设备， 以使得用户根据节目评论地址获知当前节目的评论或对当前 节目进行评论。
节目信息交流设备在将当前节目的信息提取出来后， 会判断该信息中是否 包括节目评论地址， 若该信息中包括节目评论地址， 那么节目信息交流设备会 将节目评论地址发送至用户设备， 例如， 可以通过无线路由器发送至用户设备。 用户设备在接收到来自节目信息交流设备的节目评论地址后， 可以根据节目评 论地址连接到相关网页， 那么使用该用户设备的用户， 便可获知当前节目的评 论， 也可以通过用户设备对当前节目进行评论。
S209、 若信息中不包括节目评论地址， 节目信息交流设备则将信息中的服 务器地址发送至用户设备，以使得用户设备根据服务器地址与服务器建立连接， 进而使得用户通过用户设备对当前节目进行评论。
节目信息交流设备在将当前节目的信息提取出来后， 会判断该信息中是否 包括节目评论地址， 若该信息中不包括节目地址， 那么节目信息交流设备会将 该信息中的服务器地址发送至用户设备， 同样的， 可以通过无线路由器发送至 用户设备。 用户设备在接收到来自节目信息交流设备的服务器地址后， 可以根 据服务器地址连接到服务器， 进而， 服务器会为用户设备创建该节目的评论社 区， 那么使用该用户设备的用户， 便可通过用户设备对当前节目进行评论， 进 一步地， 服务器将新建立的节目评论地址存储在该节目的信息中， 并存储在预 先建立的数据库中。
同样的在本发明实施例中， 步骤 S208与步骤 S209并没有先后的顺序， 步 骤 S208所描述的是当信息中包括节目评论地址时的情况， 步骤 S209所描述的 是当信息中不包括节目评论地址时的情况， 因此并没有时间顺序的限定。
