Providing multiple levels of interactive television service using triggers and trigger filters
First Claim
1. In an interactive system that includes a receiver having customizable configuration information specifying whether the receiver is connected or disconnected, wherein the receiver can receive both connected content that can be accessed when the receiver is connected and disconnected content that can be accessed when the receiver is disconnected, a method for preventing a viewer from being interrupted by links to inaccessible enhanced content when the receiver is disconnected, the method comprising:
- storing configuration information specifying whether a receiver is connected to, or disconnected from, a bi-directional connection to a remote source, wherein the configuration information can be customized to control when the receiver will execute a connected-content trigger that links to connected content and when the receiver will execute a disconnected-content trigger that links to disconnected content, the connected content comprising enhanced content that is accessed by the receiver when the receiver is in a connected state and the disconnected content comprising enhanced content that is accessed by the receiver when the receiver is in a disconnected state, and wherein the receiver will only execute a connected-content trigger and thereby access the connected content when the configuration information specifies that the receiver is connected;
receiving a content trigger linking to enhanced content, wherein the content trigger includes a plurality of fields, the plurality of fields including at least a location field referencing a location of the enhanced content, and a separate connectivity field indicating whether the enhanced content is connected content or disconnected content;
determining, based on a connectivity value within the connectivity field within the content trigger, whether the content trigger is a connected content trigger or a disconnected-content trigger; and
upon determining that the connectivity value distinguishes the trigger as a connected-content trigger, and upon waiting a prescribed period of time and until the configuration information indicates that the receiver is connected, executing the connected-content trigger to thereby access the enhanced content from a remote source over the bi-directional connection to the remote source.

Abstract
An interactive television system includes “connected” receiver units capable of establishing bi-directional connections to remote information stores, such as Web servers, and “disconnected” receiver units unequipped to make such connections. The system supports the use of broadcast triggers that include connectivity values indicating whether an information resource identified by a trigger refers to “connected content” or “disconnected content.” The term “connected content” refers to information resources that require bi-directional connections to remote information stores; the term “disconnected content” refers to information resources, such as a locally stored program guide, that do not require such bi-directional connections. Disconnected receiver units identify and reject connected-content triggers by examining connectivity values broadcast as part of triggers. Thus, content providers can broadcast connected-content triggers to connected and disconnected receiver units without interrupting disconnected receiver units with links to inaccessible content. Furthermore, the ability to distinguish between connected and disconnected content allows vendors who sell or lease receiver units to offer a lower level of service to those customers who do not wish to pay for the ability to access connected content.

16. A receiver having customizable configuration information specifying whether the receiver is connected or disconnected, wherein the receiver can receive both connected content that can be accessed when the receiver is connected and disconnected content that can be accessed when the receiver is disconnected, and wherein the receiver prevents a viewer from being interrupted by links to inaccessible enhanced content when the receiver is disconnected, the receiver comprising:
-
means for storing configuration information specifying whether a receiver is connected to, or disconnected from, a bi-directional connection to a remote source, wherein the connection information can be customized to control when the receiver will execute a connected-content trigger that links to connected content and when the receiver will execute a disconnected-content trigger that links to disconnected content, the connected content comprising enhanced content that is accessed by the receiver when the receiver is in a connected state and the disconnected content comprising enhanced content that is accessed by the receiver when the receiver is in a disconnected state, and wherein the receiver will only execute a connected-content trigger and thereby access the connected content when the configuration information specifies that the receiver is connected; means for receiving a content trigger linking to enhanced content, wherein the content trigger includes a plurality of fields, the plurality of fields including at least a location field referencing a location of the enhanced content, and a connectivity field indicating whether the enhanced content is connected content or disconnected content; means for determining, based on a connectivity value within the connectivity field in the content trigger, whether the content trigger is a connected content trigger or a disconnected-content trigger; and means for, upon determining that the connectivity value distinguishes the trigger as a connected-content trigger, and upon waiting a prescribed period of time and until the configuration information indicates that the receiver is connected, executing the connected-content trigger to thereby access the enhanced content from a remote source over the bi-directional connection to the remote source. - View Dependent Claims (17, 18, 19, 20)
