Abstract

The present invention defines a news story document format that supports a wide variety of news story information in a structured manner. The news story markup language of the present invention provides constraints to define timing information for a news story, to define machine control commands that may be used to automate control functions, or to associate multiple elements within one or more documents for the purpose of synchronizing the elements. The present invention defines a system and method for editing and processing news story documents.

Claims

1. A process for processing markup language documents relating to a news story, comprising the steps of:

reading an input file having a first file format including a plurality of elements, the input file further including at least one of;

timing information for representing distribution timing of the news story; and

synchronization information for synchronizing a distribution of one of the plurality of elements with a distribution of another of the plurality of elements;

the input file further including news story information for representing the news story; and

verifying the first file format of the input file based on a document type definition defining a news story markup language.

2. The process of claim 1, further comprising the steps of:

producing output data having a second file format wherein the second file format is formatted according to the document type definition; and

creating an output file based on the output data.

3. The process of claim 2, further comprising a step of converting the output file to a document file having a format different than the format of the output file.

4. The process of claim 3, wherein the format of the document file is HTML format.

5. The process of claim 3, wherein the step of converting includes the step of excluding information from the output file when converting the output file to the document file format.

6. The process of claim 1, further comprising a step of importing an import file having a file format different than the first and second file formats to produce an imported file having a format according to the document type definition.

7. The process of claim 6, wherein the step of importing includes the step of adding step import file information to a template document having a format according to the document type definition.

8. The process of claim 1, further comprising a lexical analysis step of analyzing the input file format for a plurality of elements and identifiers, and of producing an output token stream based on the plurality of elements and identifiers.

9. The process of claim 1, wherein the step of verifying further includes the steps of:

checking usage of a plurality of elements and identifiers according to the document type definition to produce a parse tree from the plurality of elements and identifiers; and

generating an output file having a hierarchical file structure based on the parse tree that conforms to the document type definition.

10. The process of claim 9, further comprising a step of interpreting the output file by a viewer.

11. A data processing system for interpreting a news story markup language document, the system comprising:

means for obtaining a news story markup language document from a storage location;

means for parsing the news story markup language document, producing a plurality of markup language tags and associated text;

means for converting the plurality of markup language tags and associated text to system instructions; and

means for converting one of said plurality of markup language tags and associated text to a machine control instruction for execution by a machine control server.

12. The data processing system of claim 11, further comprising means for rendering the system instructions as a visual interpretation of the news story markup language document.

13. The data processing system of claim 11, wherein the machine control server controls a media presentation device based upon the machine control instruction.

14. A data processing system for interpreting a news story markup language document, the system comprising:

means for obtaining a news story markup language document from a storage location;

means for parsing the news story markup language document, producing a plurality of markup language tags and associated text;

means for converting the plurality of markup language tags and associated text to system instructions;

a teleprompter; and

means for displaying story information in the teleprompter.

15. A method of anchoring document text to a control field in the same electronic document in an electronic document editor, comprising the steps of:

creating an electronic document in a markup language, said electronic document including a declarative tag enclosing the document text;

creating the control field in the electronic document, the control field having a unique identification and containing machine control information for controlling a machine control server;

referencing, at a location within the document text, the control field by the unique identification.

16. The method of claim 15, wherein the markup language is a news story markup language having news story information for representing content of the news story, the news story information including:

look information for controlling appearance of news story information; and

head information for identifying the news story.

17. The method of claim 16, wherein the machine control information identifies a presentation element associated with a media presentation device.

18. The method of claim 16, wherein the presentation element is a video element.

19. A data processing system for viewing a markup language document having a plurality of elements, the system comprising:

means for obtaining a markup language document from a storage location;

means for parsing the plurality of elements of the markup language document, producing a plurality of markup language tags and associated text, wherein the markup language document further includes at least one of;

timing information for representing distribution timing of the markup language document;

synchronization information for synchronizing a distribution of one of the plurality of elements with a distribution of another of the plurality of elements;

means for converting said markup language tags and associated text to system instructions; and

means for rendering the system instructions as a visual interpretation of the markup language document.

20. The data processing system of claim 19, wherein the markup language document includes news story information for representing content of a news story, the new story information further including:

look information for controlling appearance of news story information; and

head information for identifying the news story.
