Description
发明领域
本发明一般涉及基于万维网(“WWW”)的广播数据系统。具体地说,本发明涉及用于提供在数字广播电视网上提供单向因特网数据传递的系统和服务。
发明背景
在接下来的几年里,数字电视在美国将变成广播电视和电缆信号的基本标准。这将需要所有用户家庭购买新的数字电视机或允许旧型模拟电视将入局数字信号转换成模拟信号来观看的数字-模拟变换器系统。由于电缆信号如今是大多数电视内容的普遍提供者,所以用户还将必须购买或备有可设置在用户家里并悬挂在数字电视机上的数字机顶盒(set-top box),数字机顶盒将适于接收来自本机或区域电缆头端(headend)的入局数字信号,并转换或将它们去扰频成带有所需内容的信号以便由数字电视机广播。根据由政府和标准委员会规定的特殊标准建立数字机顶盒,而且它将改变计算功能。
因特网或WWW还在过去的20世纪成为我们生活的一部分。如今因特网的一个缺陷(downside)是为了访问它,人们必须拥有昂贵的个人计算机。尽管当今个人计算机的价格已大幅下降,但是很多人还是不希望为了访问WWW而购买一台电脑并学习它的复杂内容。此外,用当前的个人计算机还不能提供实时访问复杂的视频内容,因为必须将因特网信号带到个人计算机的传送媒体和调制解调器不够快且没有足够的带宽来使这成为可能。
一些现有技术通过将有限的专用服务器设置在用户的家里并将服务器挂在用户的模拟电视机上,尝试传送因特网信号到当前模拟电视机系统。该服务器比个人计算机要廉价得多,但是它的功能并不强。同样还存在速度问题和带宽问题,而且这些服务器在不用附近的上述数字机顶盒的情况下不与数字电视机连接。
然而,如今随着数字电视的进步以及在美国的多个社区内快速建立混合光纤同轴电缆(fiber-coax)基础结构,很快就能提供足够的带宽来有意义地向能够处理具有大量内容的数字信号的装置提供高度内容视频信号。使信号传送可行的剩下问题是传递速度,如果数字的话,那么这可由电缆调制解调器等来实现。
因此,在现有技术中长期以来都需要一种能够将因特网与将来的能够从电缆网获得内容丰富的数字信号的数字电视机体系综合起来。非常希望能通过因特网访问WWW并且因特网在将来的数字电视机上广播。此外,非常需要因特网服务与数字电视机信号无缝地结合,从而两者的客户都能够容易地访问因特网并在不中断地观看所需的内容。目前为止,在现有技术中还没有满足这些要求。
发明概述
通过一种根据本发明提供的单向广播系统来满足上述长期需要并解决上述问题。该系统最好包括适于接收MPEG数据、模拟信号和来自因特网的信号的头端电缆系统。更佳的是,本系统包括用于将模拟信号转换成MPEG信号的装置和将MPEG数据和经转换的MPEG信号组合起来的装置。更佳的是,该系统包括将组合信号传送到数字信号的装置。
根据本发明提供的广播系统还满足了上述长期需求。广播系统最好包括将因特网数据流和视频数据流组合的装置、将组合数据流传送到数字电视机的装置和综合并转换传送数据流以供数字电视机用的装置。
更佳的是,单向广播的丰富满足了这些长期需求。它们最好包括将因特网数据流和视频数据流组合、将组合数据流传送到数字电视机和综合并转换传送数据流以供数字电视机使用的步骤。
根据本发明提供的系统和方法还将因特网服务和将来的数字电视信号无缝地集成起来。本系统在电缆系统的头端中提供将MPEG视频信号与因特网信号的多路复用为能适于每个用户的特殊使用和要求的MPEG信道的功能。提供单向交互性且在本机数字机顶盒的专用软件允许系统是通用的和廉价的。而在现有技术中至今还没有达到这种结果。
MoreCast服务是运用数字电视机传送流携带的单向万维网传播(webcasting)服务。MoreCstSM向在单向数字广播电视网(诸如,混合光纤同轴电缆(HFC)或DBS(直接广播卫星))中的数字机顶盒提供万维网传播服务。该服务可为在大多数单向数字视频服务覆盖区中的网络操作者或内容提供者提供附加收入。通过利用高速宽带网带宽,MoreCastSM可从万维网向在家里的电视观众提供广播新闻、体育、本地天气和股市摘录信息。MoreCom系统还允许在广播数字视频节目的前提下广播万维网内容。对于每个数字视频节目段,用户还可接收与节目同步的万维网传播信息。例如,人们可附加访问基于万维网的信息,诸如关于当前在电视上播放的电视广告的网页。此外,用户可交互访问万维网传播信息,就象通过万维网进行网络冲浪。此外,用户可根据他的或她的爱好(例如,个人股票摘录或喜欢的体育队消息)访问专用万维网传播内容。在单向网络中,MoreCastSM使得用户能够以非常低的成本进行实时交互。
MoreCast服务有三种类型:
MoreCast广播数据:这些是在所有数字信道中到处广播到于头端相关的所有客户的HTML数据。例子包括:电子节目指南(Electronic ProgramGuide)(EPG)、MoreCom主页导航、社区信息(community information)、犯罪消息、本地天气信息、本地学校信息,等。这一般需要这些信息是关于所有物理信道的广播数据传送带(carousal)上。这样用户可以始终访问HTMC数据并在同时观看TV信道。MoreCast联播数据:基于HTML的万维网传播内容与每个数字广播电视信道相关。对于具有多个节目传送流的每个MPEG-2节目,存在数据传送带,它携带来自特定网站的用于不同服务类型的HTML数据。该传送带与数字广播节目内容同步。例子包括:节目提供者的关键网页、关于该节目的广告、关于该节目的新闻,等等。联播数据对于调谐到与该数据相关的电视节目段的所有用户都是可获得的。MoreCast个人化数据:根据每个用户的个人情况和观看时间专用化基于HTML的万维网传播内容。按统计,在特定观看期间,许多用户可能想要访问实时信息的不同子集。该信息还与每个MPEG电视节目相关,但是可不与电视内容同步。它应在所有时间内根据每个用户的要求可从数据传送带上获得。
MoreCom系统包括服务器产品和客户产品。在单向HFC网或基于卫星的传递系统中,可通过在本机头端上或卫星分布中心的MoreCom服务器启动单向万维网传播服务。可在卫星上或通过本机头端,结合数字视频,多点传播基于万维网的内容,以在MoreCom客户的电视机上提供个人化的基于因特网的内容。(MoreCast)。

较佳实施例的详细描述
现在,参照附图,其中相同标号表示相同元件,图1是本发明的单向数字电缆网10的结构的方框图。网络10包括头端20,它最好连接到混合光纤同轴电缆(“HFC”)传送网的头端20。虽然希望HFC,但是熟悉本技术领域的人员应认识到可用其它传送媒体,诸如(但不局限于)标准同轴电缆或无线。所有这些实施例都在本发明的范围内。
模拟接收机30和数字接收机40分别与MPEG-2编码器50和集成电子接收机60相连,以接收视频信号来广播到客户。在模拟信号的情况下,MPEG-2编码器50把模拟信号转换成数字MPEG-2格式。如果在数字MPEG-2格式下接收信号,那么集成接收机60以常规方式接收它们。在70处重新多路复用MPEG-2信号,并通过总线传送到根据本发明提供的广播服务器80。
最好,广播服务器80还连接到LAN90,它通过服务器100拨号访问因特网和WWW110。广播服务器80把合成数字电视和因特网信号传送到调制器120,它调制信号并把它们上变频到适当频率。变换器130把调制信号输出到HFC网140,它把信号传送到在用户家里的数字机顶盒150。MPEG-2传送流最好排列成多个数据信道,以每个传送流在一个6MHZ信道内。数字机顶盒最好包括根据本发明提供的适当软件以集成因特网和数字电视信号,并为用户提供交互性。
根据本发明,图1的系统将以超文本标记语言(HTML)的数据广播到与头端20相关的所有用户。例如,这些包括电子节目指南、导航页、社区信息、犯罪消息、天气,等等。这些数据通常是在所有6MHZ信道的广播传送带上,从而用户可以经常在同时访问这些HTML页和观看电视。为了联播数据,HTML内容与每个数字或广播电视信道相关联。对于具有多个节目传送流的每个MPEG-2节目,存在数据传送带,它携带来自特定网站的用于不同类型服务的HTML数据。传送带与数字广播节目内容同步。例如,这些包括提供者关键网页、正观看的节目有关的广告、正观看节目有关的新闻,等等。为了发送个人化数据,可根据每个用户的个人情况和观看时间定制基于HTML数据万维网传播内容。统计上,许多用户可能希望在特定观看期间访问实时信息的不同子集。该信息还与每个MPEG电视节目有关但是不与电视内容同步。它将在任何时刻根据每个用户的要求从数据传送带获得。
MoreCast(这是本发明的拥有者的商标并在通篇用来表示本发明)端到端系统提供在现有数字电视网和机顶盒广播的宽带因特网数据。图1还示出提供数字电视广播的在单向HFC网中的典型系统结构。
在数字电视网结构中,HFC头端接收来自卫星系统的模拟电视广播信道,而实时MPEG-2编码器将该信号编码成MPEG-2单个节目传送流,一般以3Mbps至8Mbps的速率传送。压缩数字格式将更加有效的把节目传送到本机HPC网。如果头端具有数字卫星下行链路集成接收机变码器(IRT),它应能够接收携带数字MPEG-2压缩流的卫星信号。它执行解调、FEC(前向纠错)和解密、然后,它输出检索到的MPEG-2多节目传送流到MPEG-2传送重多路复用器。MPEG-2重多路复用器可通过DVB(数字视频广播)ASI(异步串行接口)以最多达270Mbps的数据速率,接收单个节目传送流或多个节目传送流。由于运用64QAM调制每个6MHZ电缆信道只能适应大约27Mbps,所以需要重多路复用器来重多路复用节目以便适合这些信道。重多路复用器可以不同比特速率将单个或多个节目传送流重多路复用成多个节目传送流、重新分配PID(数据包ID)、调节PCR(节目时钟基准)和修正PAT/PMT(节目相关表/节目映射表)和插入条件访问消息,诸如ECM和EMM。
在物理层,一般64QAM调制器用于每个6MHZ电缆信道来提供27Mbps的数字容量下行流。此外,调制器还提供前向纠错(FEC)、带内下行流信道一般占模拟和数字节目共享的HFC频谱中的50MHZ到750MHZ。
用于单向万维网传播服务(MoreCastSM)的MoreGateTM(也是本发明的拥有者的商标)服务器80被设在头端以作为从本机或万维网因特网到数字视频网的万维网传播网关。可通过因特网从远程位置产生万维网传播内容。可将它们下载到MoreGateTM服务器和通过数字网“推”到数字机顶盒。将与数字电视信道相关的与节目同步的万维网内容映射到多个数据传送带上的MPEG-2传送流。该系统还允许通过万维网传播内容由数字机顶盒交互导航。
MoreGateTM服务器最好通过以太网与因特网代理服务器相连以检索万维网内容。它具有DVB ASI格式的输出,该输出携带MPEG-2的传送流。该输出馈送MPEG-2重多路复用器。由MoreCom资源管理器155(MoreManageTM)通过以太网运用SNMP对带宽和PID管理。
将MoreManage发展成管理由MoreCom(本发明的拥有者)提供的万维网传播服务。MoreManage的三个主要功能包括:(1)管理MPEG-2资源分配(PID,带宽,等)用于由MoreGate服务器提供的服务;(2)收集和保持客户情况和用途,并与记帐、OSS(操作支持系统)和用户管理系统相连;和(3)将管理接口与管理MPEG编码器、IRT、Remux(重多路复用器)和调制器的系统控制器相连。
参照图2,示出提供上述参考功能的服务器环境的系统图。在服务器侧160,设有超文本传送协议(HTTP)代理服务170,它包括希望传送的特定应用180。设置应用节目接口(API)190,它与由服务器80执行的HTML/MPEG网关和节目库200连接。由高速MPEG输入/输出接口210输出内容。
在客户侧220,将应用输入到HTTP引擎230,在此,控制块240允许客户根据特殊协议260(例如,UDP和/或IP270)导航250。MPEG-2传送驱动器280和解码器290处理输入数字信号。
在网关服务器80中,MoreCast应用模块180是主模块,它控制何时将万维网数据广播到数字视频网中。它可通过HTTP代理模块执行HTML数据读取、把该数据转换成数字机顶盒可处理的格式、安排数据事件广播的时间表请求所需的网络资源并管理数据和控制接口。HTTP代理服务器负责根据MoreCast应用模块的请求从因特网读取万维网数据。在HTML/MPEG数据协议模块中将HTML数据映射到MPEG-2传送流上。最好在控制协议模块295中产生控制映射,用于单向广播服务的导航,信道链接。通过MPEG高速I/O(诸如,DVB ASI)将数据和控制发送到数字视频网。
在客户侧220,MoreCast应用模块180具有用户接口。它把请求发送到MoreCast客户引擎,它反过来与MoreCast数据协议和MoreCast控制协议相连。MoreCast数据协议将根据来自由MoreCast控制协议提取的控制映射的导航和信道信息,通过MPEG传送专用数据部分提取万维网数据。从控制数字机顶盒中的MPEG-2传送硬件的MPEG-2传送驱动器提取数据和控制信息。
为了在上述各种选项之间导航,最好提供浏览器和导航菜单。参照图3,最好示出导航层。用户可选择数字视频信道和可在电视屏幕上启动用户界面。将启动浏览器300,而且主菜单310将示出广播320、万维网330、视频340和邮件350,它们是一些较佳的选项。例如,选择广播320启动广播子菜单360。例如,这启动广播370、联播380或个人化390选项。选择广播370启动在410中启动对于公共HTML流1、2、3的导航页400。选择联播380启动导航页420,它转到与6MHZ信道相关的一系列数据信道,从而具有在430的多个HTML事件1,2用于观看。通过选择个人化390,用户将只选择与他的或她的机顶盒相关的MAC或IP地址匹配的信道。
在用户从菜单中选择所需的特定服务之后,提供来自数据信道的相关根信道导航页。例如,如果有线新闻网(CNN)确定支持联播服务,那么它将需要产生具有到所有起始页的URL440的CNN特定信道导航页,其中所有起始页都与构成联播服务的每个簇页(cluster page)相关。用户可转到与所选流有关的万维网内容,且在每个流中,用户可转到链接到所需页的每个URL。
假定通过MoreCast提供上述服务,用户可在任何给定时刻从上述服务之一,访问任何信息。可存在多种不同的导航模块。导航模块的设计目的在于对用户友好和基于标准万维网内容。
·菜单:这是与浏览器本身不同的导航菜单。菜单系统可识别用户想访问的MoreCast服务的类型:广播、联播和个人化,因为一个人每次不能访问多于一个服务。这是完全基于HTML的并为所有用户和信道共有。大约每月下载更新一次。
·内容:通过许多数据信道可观看三种服务的所有MoreCast内容。每个数据信道具有根页,它表示数据流表。每个数据流包括一组超链接网页。在联播的情况下,流变成具有起始时间和持续时间的事件。所有内容都是基于标准的HTML。可由内容提供者通过标准万维网授权工具产生所有内容
可在下列图片中解释导航层:
1.用户可选择一个数字视频信道,例如,CNN。可在屏幕上启动MoreCast服务用户接口。它将示出MoreCom浏览器按扭,诸如“MoreCast”“MoreWeb”和“MoreVideo”和“MoreMail”等等。
2.用户可在电视机上选择MoreCast服务按扭。这将带来用于MoreCast服务的本机菜单。它将示出MoreCast服务按扭,诸如“MoreCast广播”、“MoreCast Simulcast(联播)”“MoreCast Personalized(个人化)”。选择“MoreCast Simulcast”在观看CNN同时将进到与CNN相关的数据信道。只有一个数据信道与一个视频节目相关。在一个物理信道中存在多个联播数据信道。而且只有一个广播信道为每个6MHZ共享,它们不与视频节目相关。在一个物理信道中可存在多个个人化信道。
3.在用户在本机菜单上选择MoreCast服务类型之后,它将从数据信道中获得相关根信道导航页。例如,如果CNN确定支持MoreCast联播服务,那么它将需要产生CNN特定信道导航页,它具有到关于每个簇页(数据流或事件)的所有起始页的URL,其中每个簇页构成诸如CNNfn、CNNevent(关于每个商业)等等的服务。
4.现在,用户可转到关于所选流的万维网内容。用户可在任何时刻容易地回到流的起始或信道导航页。
5.在每个流内,用户可转到按照需要链接到网页的每个URL。
参照图4,可在MPEG-2传送流上以在该附图中定义的格式携带数据和控制信息。基本上,将HTML页(URLs)和它们的控制映射信息直接映射或者通过中间层(诸如UDP/IP)映射到MPEG-2传送流部分,然后封装在MPEG-2传送流部分中。多个部分形成表格。可将每个表格分开并由机顶解码器通过tableID和/或tableID_extension字段滤波。MPEG-2表结构分段并在MPEG-2传送数据包中携带。由解码器通过PID(packetID)滤波MPEG-2数据包。
图5示出根据本发明MPEG网络的HTML导航分级。产生HTML节目相关表450。这些表格识别在所选6MHZ内的传送流中的数据信道(节目)的列表。它们还识别数据信道的类型和视频节目的链接(如果有的话),并给出节目映射表的位置。节目映射表识别在每个数据信道内的数据流以及它们的类型和性能的列表,诸如UPR至MPEG资源映射,并给出信道导航页的位置。描述符(descriptor)给出在节目表内的每个流的细节。同时,产生HTML节目映射表460、HTML事件信息表470、HTML会话信息表480。例如,节目表460支持几个HTML流490和相关URL500。事件信息表470支持特定事件510和相关URL520。类似地,会话信息表480支持HTML流530以及相关URL540。该图描述在单项数据广播环境中,导航和信道链接所需的控制映射分级。
由在头端中的服务器产生控制映射,并通过数字广播网定期将它们发送到客户。最好将控制映射分成下列分级:
·HPAT:HTML节目相关表。该表识别在所选6MHZ内的该支持流中的数据信道(节目)表。它还识别数据信道和视频节目链接的类型,如果有的话。它还给出下述其他控制映射的位置。
·HPMT:HTML节目映射表。该表识别在每个广播数据信道内的数据以及它们的类型和性能(诸如,URL至MPEG资源映射)的列表。它还给出信道导航页的位置。
·HEIT:HTML事件信息表。该表识别在联播信道内关于每个视频节目的数据事件和它们的类型以及性能(诸如URL到MPEG资源映射)的列表。
·HSIT:HTML会话信息表。该表识别在个人化数据信道内的数据流和它们的类型以及性能(诸如URL到MPEG资源映射)的列表。
参照图6,例如在550单个6MHZ信道被调谐,电视调谐到节目560和在570启动服务器主菜单。用户用本机远程装置选择所需特殊服务580(诸如,关于节目相关表450的广播)。最好,根据它相关节目映射表470,在590启动信道选择。于是,最好在600显示导航页。在任一情况下,在610完成网页导航,且观看对于信道的URL。
一旦由用户选择特殊视频信道,选择6MHZ频谱并选择在该频谱内的数字视频节目。机顶将分析在所选MPEG传送流中的HPAT。这将给出在传送流中的HPMT和HEIT和HSIT的位置。
在选择广播模式中,识别HPMT的位置,并从传送流检索。机顶将用由HPMT提供的控制信息通过在数据传送带中的广播数据导航。
在选择联播模式下,识别关于当前视频节目的HEIT的位置并从传送流检索。机顶可用由HEIT提供的控制信息通过在数据传送带中的联播数据同步和导航。
在选择个人化模式中,识别HSIT的位置,并从传送流检索。机顶可用由HSIT提供的控制信息来提供数据传送带中的个人化数据识别、更新和导航。
运用面向对象的设计,通过模块方法来构成执行本发明的计算机和软件结构。这允许改变和精炼(refine)模块以及系统设计改进。系统还满足实时代理性能。实际上,该系统可移植到任何平台,并例如可在PC视窗NT平台上执行,或者在UNIX中执行。最好用C和Visual C++5.0编程该系统,并用SQL 5.0数据库服务器。图形用户界面是万维网浏览器或以Visual C++编程。利用APACHE代理服务器或MICROSOFT代理服务器。
根据本发明提供的系统和方法提供因特网服务和将来数字电视信号的无缝一体化。该系统提供在电缆系统的头端中将MPEG视频信号和因特网信号多路复用成可适于每个用户的特殊使用和要求的MPEG信道的功能。提供单向交互,且在本机数字机顶盒中的专用软件允许该系统是通用的、经济的。这在现有技术中至今还没有达到过。
这里,描述了根据本发明提供的单向广播系统的某些较佳实施例。虽然描述和揭示了一些较佳实施例,但是熟悉本技术领域的人员应认识到修正都落在本发明的真实原理和范围内。所附权利要求书覆盖所有修正。
