    • An interactive television trigger has a time attribute value that indicates a future time when the trigger is to be executed. In many situations, the trigger is sent to the receiver unit prior to the future time (e.g., to account for bandwidth limitations or to allow prefetching of an information resource associated with the trigger). Redundant triggers may be sent as the future time draws closer. In this way, if the receiver unit did not receive a previously sent trigger for some reason, a redundant trigger is available for execution. The receiver unit may ignore duplicate triggers. The time attribute value also may indicate a life span during which the trigger is valid so that, if a user switches video channels but returns to a video channel for which execution of the trigger is desired, the trigger may be re-executed during the life span.
    • 交互式电视触发器具有时间属性值,其指示将要执行触发的将来时间。 在许多情况下,在未来的时间(例如,考虑带宽限制或允许预取与触发相关联的信息资源)的触发器被发送到接收器单元。 随着未来时间的延长,可能会发送冗余触发器。 以这种方式,如果由于某种原因接收器单元没有接收到先前发送的触发,则冗余触发可用于执行。 接收器单元可能会忽略重复触发。 时间属性值还可以指示触发有效期间的寿命,使得如果用户切换视频通道但是返回到期望触发器的执行的视频通道,则可以在生命期间重新执行触发 跨度。

    • Described are methods and apparatus for enhancing a television advertisement simultaneously displayed on a number of remote receivers. In one embodiment, one or more advertisement templates are stored in memory on each of the remote receivers. The templates include formatting information and data fields into which can be inserted predefined types of information. For example, a selected template may be adapted to receive and display an advertiser's name, product, and a hyperlink to the advertiser's web site. A content creator, (e.g., a program producer, broadcaster, affiliate, cable company or satellite provider), embeds an advertisement summary in a data service channel of a broadcast signal. The advertisement summary includes a resource identifier unique to a selected one of the advertisement templates. Upon receiving an advertisement summary directed to a resident advertisement template, the receiver combines custom advertisement information provided in the advertisement summary with formatting information provided in the advertisement template. The receiver employs the combined information to create and display a custom advertisement, which may include hyperlinks to additional produce or service information.

    • 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。

    • Described are methods and apparatus for enhancing an information resource, such as a Web page, simultaneously residing in memory on a number of remote receivers. A content creator, (e.g., a program producer, broadcaster, affiliate, cable company or satellite provider), embeds a trigger in a data service channel of a broadcast signal. The trigger includes a resource identifier unique to the information resource and a script capable of modifying the information resource. The script might be a script or a segment of a script written in a conventional scripting language. Each receiver that includes the targeted information resource monitors the data service channel of the broadcast video signal for script-bearing triggers directed to that resource. If a receiver receives a script-bearing trigger directed to the resident resource, the receiver executes the script contained within the trigger to alter the resource and/or the displayed video defined by the resource.
    • 描述了用于增强同时驻留在多个远程接收器上的存储器中的诸如网页的信息资源的方法和装置。 内容创作者(例如,节目制作人,广播公司,联盟,电缆公司或卫星提供商)将触发信号嵌入在广播信号的数据服务信道中。 触发器包括信息资源唯一的资源标识符和能够修改信息资源的脚本。 该脚本可能是一个脚本或一段以常规脚本语言编写的脚本。 包括目标信息资源的每个接收器监视广播视频信号的数据服务信道,用于指向该资源的脚本触发触发。 如果接收器接收到指向驻留资源的脚本触发触发器,则接收器执行包含在触发器内的脚本来改变由资源定义的资源和/或所显示的视频。
