摘要： A broadcast signal is received that includes a data identifier that identifies data associated with the broadcast signal. The broadcast signal also includes the data associated with the broadcast signal encoded in the broadcast signal. The data associated with the broadcast signal includes an indicator to ignore the data identifier contained in the broadcast signal. The system decodes the data encoded in the broadcast signal while ignoring the data identifier contained in the broadcast signal. The indicator to ignore the data identifier contained in the broadcast signal may include an associated time period during which the data identifier should be ignored. The data identifier is broadcast in scan line twenty-one of a broadcast image. The data associated with the broadcast signal is encoded in vertical blanking interval lines of a broadcast image.

摘要： 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.

摘要： 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.

摘要： Described are a method and apparatus for incorporating broadcast television into Web pages. Broadcast television can be embedded into Web pages using, for example, a “tv:” attribute in conjunction with common HTML tags. Within the “tv:” attribute, a Web-page author can reference a TV station by channel number, network, or broadcast call letters. HTML documents are parsed to recover both the conventional tags and tags that include TV attributes. The resulting Web pages display the identified broadcast TV in a frame specified by the TV attribute. One embodiment supports the presentation of television in the background of an HTML document. In that embodiment, HTML tags corresponding to overlying HTML content are provided with an attribute that defines a level of transparency from zero to one-hundred percent. The transparency attribute allows content providers to overlay any type of HTML information over a broadcast television show without completely obscuring the underlying show. This aspect of the invention employs a z attribute that can be used to specify the relative position of broadcast television and overlying HTML content.

摘要： An interactive television system displays a television program having an associated channel. The system also displays an interactive television mode indicator if the displayed television program supports an interactive television mode. The interactive television mode is activated in response to a request from a viewer of the television program to activate the interactive television mode. The system updates a channel status list to indicate that the television program is being viewed in the interactive television mode. The system is also able to handle requests for activating an online television mode. When changing channels, the channel status list is used to restore a previously activated interactive television mode or online television mode for a particular television channel. Two different indicators may be displayed to indicate whether the television program supports an interactive television mode and/or an online television mode.

摘要： The invention involves transmission download of data to plural, mass storage medium-based remote users of content or software upgrades or multiple versions. Optionally provided are pre-download scheduling of one or more future download sessions and post-download remote scripted software execution by the remote clients. For purposes of more efficient use of the transmission link, low-volume scheduling information or content are transmitted within designated narrow-bandwidth sub-channels or trickle streams allocated within the broad bandwidth of the transmission channel and such allocation may be dynamic to vary the allocation based upon relative high-volume, high-speed and low-volume, low-speed demands. The invention is implemented in software residing primarily in the server computer connected with the transmission provider. The software schedules allotted bandwidth within the broadcast band of the transmission link and formats high-volume data for transmission within sub-allocation channels logically devised therein. Client software at the plural distributed home entertainment device sites reserves capacity on disk and receives such transmission data for storage thereon, optionally executing a downloaded execution script that may reconfigure the client software so that new options and features are available at the client site for operational enhancements as well as video program or content enhancements. Client software at the plural distributed home entertainment device sites reserves capacity on disk and receives such broadcast data for storage thereon, optionally executing a downloaded execution script that may reconfigure the client software.

摘要： Information from an information resource may be displayed with television video in a synchronized fashion. A trigger, broadcast along with the television video, identifies the resource and indicates how information from the resource should display. When a trigger is received, the receiver unit determines whether a rule stored in the receiver unit applies to the trigger. For example, if the rule applies, the receiver unit may take a predetermined action, or if the rule does not apply, the rule may have no effect and the receiver unit may act upon the trigger in a normal or default fashion. Based on one or more rules, the receiver unit may ignore certain triggers, but not others. Rules can be automatically loaded into the receiver unit on power-up by one-way broadcast communication, from a permanent storage device, or by downloading from the Internet. The rules can be updated periodically.
