Description

说 明 书 下载节目数据的方法、 系统和终端设备 本申请要求于 2008年 02月 27日提交中国专利局、 申请号为 200810007884.8、 发明名 称为"下载节目数据的方法、系统和终端设备"的中国专利申请的优先权,其全部内容通过引 用结合在本申请中。 技术领域
本发明涉及通信领域, 特别涉及一种下载节目数据的方法、 系统和终端设备。 背景技术
IPTV (IP Television, IP电视) 是一种新兴的热门业务, 通过 IP技术向用户提供视频 直播、 点播、 电视时移等基础业务, 提供 EPG (Electronic Program Guide, 电子节目索引) 供用户方便快捷地浏览直播、 点播的节目单和增值业务服务。
EPG是 IPTV业务向用户提供的门户, 是 IPTV的一个重要组成部分, EPG的响应速度 直接影响用户满意度。但是受网络速度和质量的影响, EPG的响应速度成为 IPTV的一个难 点问题。
EPG的展示可以通过传页面或者传数据的方式, 传页面采用比较流行的浏览器 /服务器 模式, 数据的解析由 Web服务器完成, 把生成的页面传给 IPTV终端的浏览器展示; 传数 据的方式采用客户端 /浏览器模式, 数据的解析由 IPTV终端完成, EPG服务器只需向 IPTV 终端发送更新的节目单数据。 由于传数据方式受网络影响小, 可扩展性好, 逐步被大家采 用。
受 IPTV终端性能的限制, 无论是传数据的方式还是传页面的方式, 图片 (包括广告、 海报等) 一般保存在 EPG服务器上, 当用户浏览某一个节目时, 再从服务器上下载图片。 由于图片比较大, 下载和解析图片需要花费很多的时间; 如果更新的节目数据比较多时, 也会耗费很长的时间下载和解析更新的数据; 进而影响 EPG的响应速度。
为此, 现有技术提供了一种下载 EPG数据的方法, 包括:
用户开机时,把所有的 EPG数据都下载到 IPTV终端上,用户浏览 IPTV终端的节目单 时, 从本地存储中读取 EPG数据, 当 EPG数据有更新时, 则下载更新部分的 EPG数据。
在实现本发明的过程中, 发明人发现现有技术提供的下载 EPG数据的方法至少存在以 下问题:
占用 IPTV终端存储空间大: 点播节目一般有几千个或上万个, 把这些节目的数据都下 载到 IPTV终端, 需要占用很大的存储空间, 而有些点播节目很少被访问, 这些节目的相关 数据很少用到, 造成终端设备空间使用的浪费;
IPTV终端开机时间慢: 每次 IPTV终端启动时, 都需要下载更新部分的 EPG数据。 发明内容

下面将结合附图对本发明实施方式作进一步地详细描述。
本发明实施例中的 IPTV终端确定用户浏览的焦点在当前节目停留的时间到达预设时间 时, 从电子节目索引服务器下载当前节目对应的节目数据, 能够及时下载用户真正需要的 节目数据, 不需要预先存储大量的节目数据, 节省了大量的空间。
其中, IPTV终端可以是机顶盒, 也可以是手机终端等设备; 节目数据不但包括用文字 描述的节目信息, 还包括以图片、 视频和音频形式表现节目的非纯文本内容, 这些非纯文 本内容占用的存储空间比较大, 本发明实施例对这些非纯文本内容采用延时下载的方式。
参见图 1, 本实施例提供了一种下载节目数据的方法, 该方法包括:
101: 接收电子节目索引服务器发送的数据;
102: 根据接收到的数据向用户展示节目信息;
103: 确定用户浏览的焦点在当前节 0停留的时间到达预设时间时, 从电子节 0索引服 务器下载当前节目对应的非纯文本内容, 其中, 非纯文本内容包括: 图片、 视频或音频中 的一种或者任意组合, 例如当前节目对应的数据有图片数据和视频数据时, 将同时下载图 片数据和视频数据。
用户在浏览节目的过程中, 当焦点移动到某节目时, 如果该节目有对应的海报、 广告、 视频或音频等节目数据保存在 EPG服务器上, IPTV终端需要到 EPG服务器下载对应的节 目数据, 因为图片 (海报或广告)、 视频或音频等节目数据传输会有一定的延时, 造成界面 焦点移动速度变慢, 影响用户的体验。 为了提高界面的响应速度, 本实施例采用延时下载 的方法, 参见图 2, 以 IPTV终端是机顶盒, 节目数据是 VOD ( Video On-demand, 视频点 播) 海报为例, 其下载过程具体如下:
201: 用户浏览 VOD节目单时, 通过遥控器移动 EPG上的焦点位置。
202: 当焦点从一个节目移到另外一个节目时, 计时器 (焦点停留在某一个节目上的时 间) 置 0, 并开始计时, 记录焦点停留在当前节目的时间;
203: 判断焦点在当前节目停留的时间是否达到计时器的预设阈值, 如果是, 执行 204; 否则, 执行 206; 其中, 预设阈值可以为计时器的默认值, 也可以根据需要进行设定; 204: 从 EPG服务器下载当前节目的海报;
此时, 计时器的计时达到预设阈值, 说明该用户希望获取该节目上的具体信息, 则从 EPG服务器下载当前节目的海报;
205: 更新显示界面上的图片为当前节目对应的海报;
206: 在计时器的计数未达到预设阈值时焦点移动, 不下载当前节目的海报, 计时器清
0。
在本实施例中, 当用户浏览的焦点在当前节目停留的时间达到预设时间时, 从 EPG服 务器下载当前节目对应的非纯文本内容, 在不影响用户读取 EPG数据的基础上, 不需要预 先将所有 EPG服务器上的 EPG数据都下载到 IPTV终端, 只下载用户真正需要的非纯文本内 容, 节省了非纯文本内容对 IPTV终端空间的占用, 进而降低了对 IPTV终端容量的要求, 提高了 IPTV终端的启动速度。 本发明实施例提供了一种下载节目数据的方法, 该方法通过分类下载数据的方式或分 段下载数据的方式实现, 该方法可以与图 1 所示的提供的下载节目数据的方法结合使用, 也可以独自使用。
1 ) 分类下载数据的方式如下:
当用户进入当前级别的点播栏 0时, IPTV终端将向 EPG服务器发送下载请求,通知 EPG 服务器用户进入的栏目的级别, 用以下载当前级别的点播栏目的下一级别子栏目数据或当 前级别的点播栏目的内容数据;
EPG服务器收到进入某一个级别的栏目请求时,读取数据库或内存中该级别栏目的下一 级子栏目或该级别栏目对应节目的内容数据, 然后将读取到的这一级别的节目数据传送给 IPTV终端。
例如: 在首次进入点播界面时, 只将第一级点播栏目相关的数据从 EPG服务器上下载 下来, 展示给用户, 当用户移动焦点进入下一级点播栏目时, 再向 EPG服务器发送对应的 点播栏目信息下载请求。
2) 分段下载数据的方式如下:
当用户进入的当前级别的点播栏目的子栏目或节目数据超过预设个数时, IPTV终端将 根据用户的浏览情况逐次从 EPG服务器下载指定个数的当前级别的点播栏目的下一级别子 栏目数据或当前级别的点播栏目的内容数据。
其中, 用户的浏览情况有多种, 例如: 当前级别的点播栏目的下一级子栏目总共为 200 个, 当用户初次浏览该当前级别的点播栏目时, 从 EPG服务器下载下一级子栏目的前 50个 子栏目, 当用户浏览到第 40个子栏目时, 从后面的 150个子栏目中下载前 100个子栏目, 当用户浏览到第 140个子栏目时, 下载剩余的 50个子栏目。
从 EPG服务器下载下一级别子栏目数据或当前级别的点播栏目的内容数据的个数可以 在 EPG服务器端进行设置, 也可以由 IPTV终端在请求下载数据时通知给 EPG服务器, 或者 采用系统默认的个数, 例如 20个。
上述分段下载数据的方式具体如下:
当用户进入当前级别的点播栏目时, IPTV终端向 EPG服务器发送当前点播的栏目的请 求;
EPG服务器收到当前点播的栏目的请求后,从数据库或内存中读取当前点播的栏目的子 栏目或节目数据, 如果这级栏目的子栏目或节目数据 M比较大, 则只把该栏目的前 N个子 栏目或节目数据传送给 IPTV终端。
当用户即将浏览该栏目的第 N个子栏目或节目数据时, IPTV终端向 EPG服务器请求新 的节目数据, EPG服务器将读取该栏目的下 N个子栏目或节目数据给 IPTV终端, 由 IPTV 终端生成对应的文件显示给用户。
例如: 某个点播栏目下有 1000个点播节目, 当用户选择进入这个点播栏目的时候, 首 先下载前 200个点播节目, 进行解析和展示。 当用户通过翻页、 移动焦点到第 180个点播 节目的时候, 再向 EPG服务器发送请求, 请求后 200个点播节 0信息。
当上述分类下载数据的方式或分段下载数据的方式与实施例 1 提供的下载方法结合使 用时, 先通过分类或分段下载数据的方式将当前点播栏目下的部分内容显示给用户, 当用 户浏览的节目下没有子栏目时, 如果用户浏览的焦点在该节目停留的时间到达预设时间时, 从 EPG服务器下载当前节目对应的非纯文本内容。
本实施例提供的分类和分段下载方式下载节目数据, 并不是在 IPTV终端开机时将所有 的节目信息都下载到本地, 而是等到用户真正需要的时候再下载相关内容, 提高了 IPTV终 端的开机速度, 加快了界面的响应, 进而提升了用户体验。 参见图 3, 一种下载节目数据的系统, 包括终端设备 300和服务器 400, 其中, 终端设 备包括:
接收模块 301, 用于接收服务器发送的数据;
展示模块 302, 用于根据接收模块 301接收到的数据向用户展示节目信息;
延时下载模块 303, 用于确定用户浏览的焦点在当前节目停留的时间到达预设时间时, 向服务器发送下载当前节目对应的非纯文本内容的请求, 非纯文本内容包括图片、 视频或 音频中的至少一种;
服务器 400 用于接收终端设备发送的下载当前节目对应的非纯文本内容的请求, 从数 据库或内存中读取当前节目对应的非纯文本内容, 将当前节目对应的非纯文本内容发送给 终端设备。
下面以机顶盒作为 IPTV终端, EPG服务器作为提供节目数据的服务器进行说明, 本实 施例中的机顶盒的功能是响应遥控器的按键,从 EPG服务器上下载节目数据并展示给用户, 接收和控制来自多媒体服务器的媒体流并播放出来。参见图 4, 为下载节目数据的系统的结 构图, 该系统包括: 机顶盒 500和 EPG服务器 600, 其中, 机顶盒 500包括:

数据读取模块 601, 用于接收机顶盒发送的下载请求, 根据请求的内容从数据库或内存 中读取对应的数据;
数据发送模块 602, 用于将数据读取模块 601读取的数据发送给机顶盒。
通过图 4提供的系统下载节目数据的具体过程如下:
1 ) 机顶盒接收用户发送的请求命令, 例如: 遥控器的按键操作信息, 通过网络传输协 议 (例如, HTTP (Hypertext Transfer Protocol, 超文本传输协议)) 将请求命令发送给 EPG 服务器的数据读取模块 601 ;
2) EPG服务器的数据读取模块 602收到请求命令后, 从数据库或内存中读取请求对应 的数据交给数据发送模块 602;
3 ) EPG服务器的数据发送模块 602通过 HTTP协议把数据发送给机顶盒的接收模块
501; 4) 机顶盒的接收模块 501接收到的数据后, 将数据交给展示模块 502, 展示模块 502 通过数据解析单元 5021把数据按照一定的结构存储;
5 ) HTML封装单元 5022对按结构存储的数据和 HTML标签进行封装, 生成 HTML文 件;
6) HTML解析单元 5023解析生成的 HTML文件, 并以网页的形式在机顶盒上展示出 来;
7)当用户焦点在当前网页停留的时间到达预设时间, 且该网页有非纯文本内容(图片、 视频或音频)时, HTML解析单元 5023通知延时下载模块 503下载该网页的非纯文本内容, 然后由展示模块 502播放或显示下载的非纯文本内容。 其中, 预设时间可以根据需要, 提 前设置, 例如为 1秒或 2秒等, 具体实现时, 可以通过显示界面上的计时器进行计时实现。
