现有计算机技术中, IE浏览器根据 URL ( Uni form / Univer sa l Resource Loca tor , 统一资源定位符) 从 Web Server (网站服务器) 获取 FTP (文件 传输协议) 或者 HTML ( Hyper Text Mark-up Language , 超文本标记语言) 数据, 并根据 HTML语言描述转为网页界面, 呈现在显示器上供用户查看。 因此, 只要能将 IE浏览器显示在显示器上的内容通过某种方法转换成视频 形式发送给电信视频资源平台, 再由电信视频资源平台发送给终端用户或 者直接发送给电信网络中的设备, 即可实现将网页内容播放给用户。 这样 就可以使用网页编辑工具快速、 方便的开发实时信息的电信视频业务, 达 到所见即所得的效果。
实施例一:

可选的, 发送视频形式的显示内容, 可以包括: 向电信视频资源平台发 送视频形式的显示内容, 其中, 所述视频形式为图片或者媒体流; 或者向 电信网络中的设备发送视频形式的显示内容, 该电信网络中的设备可以包 括如下之一: IP多媒体系统 (IP Multimedia Subsystem, IMS) 网络的终 端、 或下一代网络 (Next Generation Network, NGN) 的终端、 或电信网 络中的 3G视频网关 (Video Gateway, VIG) 。 视频形式的显示内容的网络 传输协议可以为实时传送协议 (Real-time Transport Protocol, RTP) 和 RTP控制协议 (RTP Control Protocol, RTCP) 。
可选的,可以通过如下会话建立方式之一与所述电信视频资源平台建立 会话后, 向所述电信视频资源平台发送所述视频形式的显示内容: FTP、 HTTP, 会话初始化协议 (Session Initiation Protocol, SIP) 、 实时流 传输协议 (Real Time Streaming Protocol, RTSP) 。
本发明实施例上述方法技术方案因为采用接收来自电信视频资源平台 的视频内容获取请求; 根据视频内容获取请求获取视频内容获取请求对应 的网站服务器的数据内容; 将数据内容转换为视频形式的显示内容; 发送 视频形式的显示内容的技术手段, 所以具有根据动态信息, 实时动态生成 视频内容的能力, 在电信网络中提供实时视频业务。
实施例二:
本发明实施例上述方法技术方案中将网页内容转换为视频内容的设备 可称之为视频转换服务器, 其和电信视频资源平台、 网站服务器和电信网 络中的设备的组网关系如图 2所示, 需要说明的是, 该视频转换服务器 23 可以位于电信视频资源平台 22 (该电信视频资源平台 22和电信网络中的设 备 21相连) 和网站服务器 24之间, 也可以集成在网站服务器 24上, 本发 明实施例并不以此为限。
如图 3所示,为本发明实施例一种在电信网络中提供实时视频业务的视 频转换服务器结构示意图, 所述视频转换服务器包括:
接收单元 301, 用于接收来自电信视频资源平台的视频内容获取请求; 获取单元 302,用于根据视频内容获取请求获取视频内容获取请求对应 的网站服务器的数据内容;
转换单元 303, 用于将数据内容转换为视频形式的显示内容;
发送单元 304, 用于发送视频形式的显示内容。
可选的, 获取单元 302, 进一歩可以用于根据视频内容获取请求中的统 一资源定位符 URL, 获取 URL对应的网站服务器的网页形式的数据内容。发 送单元 304,进一歩可以用于向所述电信视频资源平台发送所述视频形式的 显示内容, 其中, 所述视频形式可以为图片或者媒体流, 或者可以用于向 电信网络中的设备发送所述视频形式的显示内容, 所述电信网络中的设备 可以包括如下之一: IMS网络的终端、 或 NGN网络中的终端、 或电信网络中 的 VIG。 发送单元 304, 用于发送所述视频形式的显示内容的网络传输协议 可以为 RTP和 RTCP。

以下分别进行详细介绍:
1 ) 如图 4所示, 为本发明应用实例一在电信网络中提供实时视频业务 的流程示意图, 具体包括:
401、视频转换服务器接收来自电信视频资源平台的视频内容获取请求, 该视频内容获取请求包含了 URL。
402、 视频转换服务器解析上述视频内容获取请求, 获取视频内容获取 请求包含的 URL, 并根据 URL获取该 URL对应的网站服务器地址信息。 403、视频转换服务器根据上述网站服务器地址信息,使用 HTTP协议请 求网站服务器的网页内容。
404、 视频转换服务器接收上述网站服务器发送的网页内容。
405、 视频转换服务器将网页内容转换为视频内容。
此处, 视频转换服务器可以通过一台计算机实现该功能, 基于 IE浏览 器, 以 Tr ident 为内核, 利用抓屏的方式 ( VC6. 0 ) , 这种方式最简单, 访问的网页需要在屏幕上显示才能获取。 而且超出屏幕或被其他窗体挡住 就不能获取完整。 或者通过 WM_PRINT进行绘制, 可以抓取超出屏幕和被其 他窗体挡住的画面。 还可以使用 IHTMLDocument 2提供的接口实现不显示网 页 来 抓 图 , 例 如 IHTMLDocument 2_ IHTMLElement - IHTMLElement Render:: DrawToDC 方式 (VC7. 0) 、 IHTMLDocument 2 - IViewObject:: Draw (C# ...)等, 基于 IE内核的推荐最好的方式是使用 COM 对象 IViewObject提供的 Draw方法, 利用计算机通过上述方式即可以实现 将网页内容转换为视频内容。
406、 视频转换服务器将视频内容生成图片文件, 并将图片文件保存到 文件服务器。
需要说明的是,该文件服务器可以是独立存在的物理实体,也可以是集 成在视频转换服务器或者电信视频资源平台上的。 视频转换服务器保存到 文件服务器的图片格式只要电信视频资源平台支持即可, 例如 BMP、 JPG等 图片格式。
407、 视频转换服务器向电信视频资源平台发送转换成功消息, 该转换 成功消息表明了网页的视频内容已经成功转换为图片文件了, 并且该消息 还可以包含了该图片文件对应的图片文件名。
保存在文件服务器上的图片文件名也可以是电信视频资源平台在向视 频转换服务器发请求时就指定的, 在歩骤 406 中, 当视频内容生成图片内 容时, 相应的图片文件名就是电信视频资源平台指定的。 408、电信视频资源平台根据上述图片文件名向文件服务器中获取请求, 该获取请求包含了上述图片文件名。
409、 文件服务器接收到获取请求后, 根据图片文件名, 将该图片文件 名对应的图片文件发送给电信资源平台。
410、 电信视频资源平台将获取的图片文件转换为视频流数据, 发送到 电信网络中。
此处, 视频转换服务器可以通过一台计算机实现该功能。 可以通过 RTP 和 RTCP网络传输协议发送给电信网络中的设备, 需要说明的是, 还可以通 过 H. 324M协议等其他协议传输视频流, 本发明实施例并不以此为限。
上述本发明应用实例应用于动态信息变化较少的场景中,之所以要中途 生成图片文件, 是因为对于有些比如显示表格的视频流, 画面变化很少, 可以通过抓图软件截取不同的显示画面, 保存为图片文件, 节省存储空间, 还可以提升视频转换服务器和电信视频资源平台的处理性能。
2 ) 如图 5所示, 为本发明应用实例二在电信网络中提供实时视频业务 的流程示意图, 具体包括:
501、 视频转换服务器接收来自电信视频资源平台发送的视频内容获取 请求,该视频内容获取请求为 I nv i t e报文,该视频内容获取请求包含了 URL。
502、 视频转换服务器接收到上述视频内容获取请求后, 向电信视频资 源平台返回 1 00 Tryi ng消息。
503、 视频转换服务器向电信视频资源平台发送 180 A l er t ing报文。
504、 视频转换服务器解析上述视频内容获取请求, 获取到 URL对应的 网站服务器地址信息。

507、 视频转换服务器将网页内容转换为视频流, 并确定视频编解码格 式, 以及确定发送 RTP和 RCTP网络传输协议的视频流的 IP地址信息, 该 IP地址信息即为上述电信视频资源平台的地址信息。
此处,视频转换服务器可以通过一台计算机实现该功能,具体实现参见 上文。
508、 视频转换服务器向电信视频资源平台反馈 S IP 标准协议 200 0K 报文。
509、视频转换服务器根据确定的 IP地址信息发送转换的视频流到电信 视频资源平台, 最后通过电信视频资源平台发送到电信网络中。
上述本发明应用实例应用于动态信息变化较多的场景中,此处之所以要 把视频流发送电信视频资源平台, 是因为电信视频资源平台需要处理视频 流, 例如当电信网络中的设备支持的是 H. 324 复用流方式的视频流且电信 网络中无独立 VIG设备时, 需要通过电信视频资源平台进行 H. 324复用流 方式的视频流的打包。 另外, 当电信网络中的设备和视频转换服务器没有 编解码交集时, 需要通过电信视频资源平台进行视频流编解码格式的转换, 转换成电信网络中的设备可以接受的编解码格式。
3 ) 如图 6所示, 为本发明应用实例三在电信网络中提供实时视频业务 的流程示意图, 具体包括:
601、 视频转换服务器接收来自电信视频资源平台发送的视频内容获取 请求和远端会话描述协议 (Ses s ion Descr i pt ion Protocol , SDP) 报文, 该视频内容获取请求和 SDP报文为 Invi te报文, 该视频内容获取请求包含 了 URL, 该 SDP报文包含了电信网络中的设备的地址信息。
602、视频转换服务器接收到上述视频内容获取请求和远端 SDP报文后, 向电信视频资源平台返回 100 Trying消息。
603、 视频转换服务器向电信视频资源平台发送 180 Aler t ing报文。

605、视频转换服务器根据上述网站服务器地址信息,使用 HTTP协议请 求网站服务器网页内容。
606、 视频转换服务器接收上述网站服务器发送的网页内容。
607、 视频转换服务器将网页内容转换为视频流, 并确定视频编解码格 式, 以及确定发送 RTP和 RCTP网络传输协议的视频流的 IP地址信息, 该 I P地址信息即为上述电信网络中的设备的地址信息。
608、 视频转换服务器向电信视频资源平台反馈 S IP 标准协议 200 0K 报文。
609、 视频转换服务器根据确定的上述电信网络中的设备的地址信息发 送转换的视频流到电信网络中的设备。
该电信网络中的设备可以是 IMS中的终端,或 NGN网络中的终端,也可 以是电信网络中的 VIG网关。
上述本发明应用实例应用于动态信息变化较多的场景中,此处如果确定 转换成的视频流电信网络中的设备可以接受, 则可以直接发送给电信网络 中的设备, 而不用通过电信视频资源平台进行视频流编解码格式的转换, 转换成电信网络中的设备可以接受的编解码格式。
4 ) 如图 7所示, 为本发明应用实例四在电信网络中提供实时视频业务 的流程示意图, 具体包括:
701、视频转换服务器接收来自电信视频资源平台发送的 RTSP协议描述 报文。
702、 视频转换服务器向电信视频资源平台发送 200 0K报文。

706、 视频转换服务器解析上述视频内容获取请求, 获取到 URL对应的 网站服务器地址信息。
707、视频转换服务器根据上述网站服务器地址信息使用 HTTP协议请求 网页内容。
708、 视频转换服务器接收上述网站服务器发送的网页内容。
709、 视频转换服务器将网页内容转换为视频流, 并确定视频编解码格 式, 以及确定发送 RTP和 RCTP网络传输协议的视频流的 IP地址信息, 该 IP地址信息即为上述电信视频资源平台的地址信息。
710、 视频转换服务器向电信视频资源平台反馈 RTSP标准协议 200 0K 报文。
711、视频转换服务器根据确定的 IP地址信息发送转换的视频流到电信 视频资源平台, 最后通过电信视频资源平台发送到电信网络中。
上述本发明应用实例应用于动态信息变化较多的场景中,此处之所以要 把视频流发送电信视频资源平台, 是因为电信视频资源平台需要处理视频 流, 例如当电信网络中的设备支持的是 H. 324 复用流方式的视频流且电信 网络中无独立 VIG设备时, 需要通过电信视频资源平台进行 H. 324复用流 方式的视频流的打包。 另外, 当电信网络中的设备和视频转换服务器没有 编解码交集时, 需要通过电信视频资源平台进行视频流编解码格式的转换, 转换成电信网络中的设备可以接受的编解码格式。
5 ) 如图 8所示, 为本发明应用实例五在电信网络中提供实时视频业务 的流程示意图, 具体包括:
801、视频转换服务器接收来自电信视频资源平台发送的 RTSP协议描述 报文。
802、 视频转换服务器向电信视频资源平台发送 200 0K报文。 803、视频转换服务器接收电信视频资源平台发送的设置本端 SDP报文, 该报文包含了电信网络中的设备的地址信息。
需要说明的是, 该歩骤与图 7中的对应歩骤 703相比, SDP报文包含的 地址信息是不一样的, 歩骤 703 中, 电信视频资源平台如果确定转换成的 视频流电信网络中的设备可以接受, 则可以直接在 SDP报文包含电信网络 中的设备的地址信息, 将包含该地址信息的 SDP报文发送给视频转换服务 器, 后期由视频转换服务器直接将转换成功的视频流发送给电信网络中的 设备, 而不用通过电信视频资源平台进行视频流编解码格式的转换, 转换 成电信网络中的设备可以接受的编解码格式。 由于该实施例与图 7 中的实 施例中电信视频资源平台都是应电信网络中的设备的请求 (该请求包含电 信网络中的设备的地址信息) , 从而向视频转换服务器发送的视频内容获 取请求, 所以电信视频资源平台可以通过电信网络中的设备的请求获取电 信网络中的设备的地址信息。
804、视频转换服务器向电信视频资源平台发送 200 0K视频转换服务器 SDP确认报文。
805、视频转换服务器接收来自电信视频资源平台的视频内容获取请求, 该视频内容获取请求包含了 URL。
806、视频转换服务器解析上述视频内容获取请求中的 URL,获取到 URL 对应的网站服务器地址信息, 并通过上述设置本端 SDP报文得知电信网络 中的设备的地址信息。

808、 视频转换服务器接收上述网站服务器发送的网页内容。
809、 视频转换服务器将网页内容转换为视频流, 并确定视频编解码格 式, 以及确定发送 RTP和 RCTP网络传输协议的视频流的 IP地址信息, 该
I P地址信息即为上述电信网络中的设备的地址信息。 810、 视频转换服务器向电信视频资源平台反馈 RTSP标准协议 200 0K 报文。
811、 视频转换服务器根据确定的上述电信网络中的设备的地址信息发 送转换的视频流到电信网络中的设备。
该电信网络中的设备可以是 IMS中的终端,或 NGN网络中的终端,也可 以是电信网络中的 VIG网关。
上述本发明应用实例应用于动态信息变化较多的场景中,此处如果确定 转换成的视频流电信网络中的设备可以接受, 则可以直接发送给电信网络 中的设备, 而不用通过电信视频资源平台进行视频流编解码格式的转换, 转换成电信网络中的设备可以接受的编解码格式。 可选的, 上述图 3中的接收单元 301, 进一歩可以用于通过视频转换服 务器管理节点分发视频内容获取请求后, 接收电信视频资源平台发送的所 述视频内容获取请求。 如图 9所示, 为本发明实施例在图 2 的基础上的增 加视频转换服务器管理节点后的改进结构示意图, 该视频转换服务器管理 节点 25负责管理和分配多个视频转换服务器 23。
如图 10所示, 为本发明应用实例六在电信网络中提供实时视频业务的 流程示意图, 具体包括:
1001、视频转换服务器管理节点接收电信视频资源平台发送的视频转换 服务请求, 该视频转换服务请求为 Invi te报文, 用于请求视频转换服务。
1002、视频转换服务器管理节点在视频转换服务器集群中选择一个视频 转换服务器。
需要说明的是,本发明实施例可以根据负荷分担原则(比如可以考虑视 频转换服务器的忙碌情况、 负荷情况等因素) 在视频转换服务器集群中选 择一个视频转换服务器, 这只是一个实例, 也可以是其它的分配方式, 本 发明实施例并不以此为限。 1003、视频转换服务器管理节点向电信视频资源平台发送 SIP消息,该 SIP消息中包含分配的视频转换服务器 IP地址信息, 由分配的该视频转换 服务器为电信视频资源平台提供视频转换服务。
1004、 视频转换服务器接收电信视频资源平台发送的视频内容获取请 求, 该视频内容获取请求包含了 URL。
1005、 视频转换服务器向电信视频资源平台发送 100 Trying消息。

1012、 视频转换服务器根据确定的 IP地址信息发送转换的视频流到电 信视频资源平台, 最后通过电信视频资源平台发送到电信网络中。
上述本发明应用实例应用于视频内容获取请求业务量大的场景中,随着 业务量的增大, 系统中可能会存在多套视频转换服务器, 此时即可由电信 视频资源平台统一管理, 可以采用上述应用实例中的方式和增加的一个视 频转换服务器管理节点部件交互, 由该视频转换服务器管理节点管理和分 配视频转换服务器, 电信视频资源平台需要视频转换服务时, 只需先和视 频转换服务器管理节点交互获取分配的视频转换服务器资源即可。
