Abstract
An ITV application definition language (ADL) used to generate ITV applications for different types of target platforms and devices. The ADL provides a plurality of core data structure types upon which one or more data structures may be built. Data structures storing ITV content presentation and behavior information are referred to as resources. A resource is associated with a globally unique identifier that allows the data structure to be efficiently stored and retrieved from a hash table. A resource is also associated with an expiration time stamp that indicates when the resource is to be freed from memory. A resource is of arbitrary length, and contains values that differ from the default values stored at a receiving client device. Resources are also packaged into a module that may be catered to a platform and/or profile of a receiving client. The client may quickly determine whether the module is relevant to it by examining the platform and/or profile ID contained in a header of the module.
Claims (23)
1. An interactive television (ITV) system comprising:
an authoring tool generating an ITV application, the ITV application including presentation information represented via a plurality of data structures built based on one or more predetermined data structure types; and an execution engine receiving and executing the ITV application and providing an associated interactive event, the execution engine storing a plurality of default values for the presentation information and retrieving the default values in response to an absence of corresponding values in the plurality of data structures.
an authoring tool generating an ITV application, the ITV application including presentation information represented via a plurality of data structures built based on one or more predetermined data structure types; and an execution engine receiving and executing the ITV application and providing an associated interactive event, the execution engine storing a plurality of default values for the presentation information and retrieving the default values in response to an absence of corresponding values in the plurality of data structures.
2. The system of claim 1, wherein the ITV application includes behavior information describing how the application behaves in response to an external event, the behavior information being stored in a data structure separate from the data structure storing the presentation information.
3. The system of claim 1, wherein the plurality of data structures are of variable length.
4. The system of claim 1, wherein each data structure is referenced by a unique identifier associated with a memory location for the data structure.
5. The system of claim 4, wherein a portion of the unique identifier uniquely identifies a creator of the data structure.
6. The system of claim 1 further comprising:
an interchange formatting system generating a compact representation of the ITV
application prior to delivery to the execution engine.
an interchange formatting system generating a compact representation of the ITV
application prior to delivery to the execution engine.
7. The system of claim 6, wherein the compact representation is a binary representation.
8. The system of claim 1, wherein a first of the plurality of data structures inherits properties associated with a second of the plurality of data structures.
9. The system of claim 8, wherein the plurality of data structures are packaged into a module having header information.
10. The system of claim 9, wherein the execution engine examines the header information for determining a relevance of the module to the execution engine.
11. The system of claim 8, wherein the plurality of data structures are packaged into a module catered to a particular platform of a receiving client.
12. The system of claim 8, wherein the plurality of data structures are packaged into a module catered to a particular profile of a receiving client.
13. The system of claim 1, wherein one of the plurality of data structures are built based on a dictionary data structure type that maps symbols to unique identifier values.
14. The system of claim 13, wherein a symbol is associated with an event, and the unique identifier value mapped to the event identifies an action data structure.
15. An authoring tool generating an ITV application, the authoring tool comprising:
means for storing and organizing a first portion of interactive content presentation or behavior information in a first data structure generated based on one or more base data structure types, the first data structure including a symbol mapped to a unique identifier value, the unique identifier value referencing a second data structure; and means for storing and organizing a second portion of interactive content presentation or behavior information in the second data structure.
means for storing and organizing a first portion of interactive content presentation or behavior information in a first data structure generated based on one or more base data structure types, the first data structure including a symbol mapped to a unique identifier value, the unique identifier value referencing a second data structure; and means for storing and organizing a second portion of interactive content presentation or behavior information in the second data structure.
16. The authoring tool of claim 15, wherein a portion of the unique identifier uniquely identifies a creator of the data structure.
17. The authoring tool of claim 15, wherein the second data structure inherits properties defined by the first data structure.
18. The authoring tool of claim 17, wherein the properties are visual presentation properties.
