    • A method and apparatus for communicating logical addresses within a broadcast television signal are provided. According to one aspect of the present invention, a logical address of a resource, e.g., a Uniform Resource Locator (URL), may be communicated to a receiving device, such as a set-top box, by way of a data service channel of a video signal. A sequence of data complying with a predetermined syntax and including the logical address is embedded in either a text service channel (e.g., T1, T2, T3, T4) or a captioning service channel (e.g., CC1, CC2, CC3, CC4) of the vertical blanking interval (VBI) of the video signal. According to another aspect of the present invention, a logical address of a resource may be received by way of a data service channel of a video signal. A video signal including data associated with one or more data services is received. Subsequently, a sequence of data complying with a predetermined syntax is retrieved from either a captioning service or a text service. Ultimately, a logical address may be extracted from the video signal by parsing the sequence of data. importantly, features of the present invention are applicable to many broadcast television (TV) systems including National Television Standards Committee (NTSC), Phase Alternate Lines (PAL), and Sequential Couleur Avec Memoire (SECAM) as well as the proposed High Definition Television (HDTV) standard. Further, the present invention is transport-independent thereby allowing a variety of transport mechanisms, such as analog cable, digital satellite, digital TV, cable TV and others, to be employed.
    • 提供一种用于在广播电视信号中传送逻辑地址的方法和装置。 根据本发明的一个方面,资源(例如统一资源定位符(URL))的逻辑地址可以通过数据服务信道的方式传送到诸如机顶盒的接收设备 视频信号。 符合预定语法并包括逻辑地址的数据序列被嵌入在文本服务信道(例如,T1,T2,T3,T4)或字幕服务信道(例如,CC1,CC2,CC3,CC4)中 视频信号的垂直消隐间隔(VBI)。 根据本发明的另一方面,可以通过视频信号的数据服务信道来接收资源的逻辑地址。 接收包括与一个或多个数据服务相关联的数据的视频信号。 随后,从字幕服务或文本服务检索符合预定语法的数据序列。 最终,可以通过解析数据序列从视频信号中提取逻辑地址。 重要的是,本发明的特征可应用于许多广播电视(TV)系统,包括国家电视标准委员会(NTSC),相位交替行(PAL)和顺序Couleur Avec Memoire(SECAM)以及所提出的高分辨率电视 HDTV)标准。 此外,本发明是独立于传输的,从而允许使用各种传输机制,例如模拟电缆,数字卫星,数字电视,有线电视等。

    • In interactive television, information from an information resource may be displayed along with television video in a synchronized fashion. When information is to be displayed at a point in the television video, a Uniform Resource Identifier (URI) that identifies the information resource is broadcast along with the television video on a one-way broadcast communication channel. A receiver unit receives the URI from the broadcast channel. If the information resource identified by the URI is available locally (for example, is present in local storage on the receiver unit), then the receiver unit uses the URI to retrieve the information resource locally. If, on the other hand, the information resource is not available locally, then the receiver unit uses the URI to retrieve the information resource from the Internet. The information resource can therefore be received from a high speed source (for example, from VBI lines 10-20) if such reception is possible, but if such reception is not possible then the information resource can be retrieved. from another source (for example, from the Internet). Once the receiver unit has retrieved the information resource, the receiver unit can display the information along with the television video.
    • 在交互式电视中,来自信息资源的信息可以以电视视频同步显示。 当在电视视频中的某个点显示信息时,识别信息资源的统一资源标识符(URI)与电视视频一起在单向广播通信信道上被广播。 接收机单元从广播信道接收该URI。 如果URI识别的信息资源在本地可用(例如,存在于接收机单元的本地存储器中),则接收器单元使用该URI来本地检索信息资源。 另一方面,如果信息资源在本地不可用,则接收器单元使用URI从因特网检索信息资源。 因此,如果这样的接收是可能的,则可以从高速源(例如,从VBI线10-20)接收信息资源,但是如果这样的接收是不可能的,则可以检索信息资源。 来自另一个来源(例如,从互联网)。 一旦接收器单元检索到信息资源,接收器单元就可以显示与电视视频一起的信息。
