Abstract

A live event may be broadcasted by producing a computer coded description of the sub-events that constitute the event. The coded description is stored in a centralized computer data base and the information thus stored is accessible by a viewer'"'"'s computer. That viewer computer then produces a computer simulation of the live event using the coded description.

Claims

1. A method of broadcasting information about a live event that is composed of a sequence of discrete sub-events wherein a set of rules governs the event so that a status change resulting from the occurrence of a sub-event is determined by the set of rules, comprising the steps of:

creating a set of symbols useful in a computer simulation, wherein each symbol is representative of an action involving physical exertion and skill;

generating a sequence of symbolic descriptions, each description being a representation of one of the discrete sub-events, and includes at least one symbol from said set of symbols wherein said symbol may be used in a computer simulation to effect a change in an indicated status of an event in connection with a computer simulation program that operates in accordance with the set of rules governing the event;

creating a database file corresponding to the event;

updating said database file with a generated sequence of symbolic descriptions; and

broadcasting said symbolic descriptions in said updated database file.

2. The method of claim 1, in which each said symbolic description includes at least one action description, each action description including a value for at least one parameter associated with said action code.

3. The method of claim 2 further comprising the steps of:

creating said predetermined discrete set of action codes representative of a finite set of actions which can occur during the live event; and

predetermining a set of parameters for each of said action codes.

4. The method of claim 2 wherein said step of generating occurs at a first location remote from said step of creating a database file, and wherein said step of updating comprises the step of automatically transmitting said symbolic descriptions representing a sub-event from said first location to said database file after said symbolic description is generated.

5. The method of claim 2 wherein said sequence of symbolic descriptions is generated by a computer based on inputs received, said inputs describing the actions that comprise the live event and wherein said symbolic descriptions are source information for a computer simulation of the live event.

6. The method of claim 5 wherein said step of generating occurs at a first location remote from said step of creating a database file and wherein said step of updating comprises the step of automatically transmitting said symbolic descriptions representing a sub-event from said first location to said database file after said symbolic description is generated.

7. The method of claim 6 wherein in said step of broadcasting, a symbolic description received by said database file in updating the database file of an event is retransmitted so as to be receivable, either immediately after the database file is updated or at a later time, at a second location remote from said database file.

8. The method of claim 6 wherein in said step of broadcasting said symbolic description received by said database file of an event is stored, the stored symbolic description being accessible upon request from a computer at a second location remote from said data base file.

9. A method for simulating a live event that is composed of a sequence of discrete sub-events at a viewer computer at a location different from the location of the live event, with the event being governed by a set of rules that predetermines the consequences of actions that define the sub-events, comprising the steps of:

creating a set of symbols useful in a computer simulation, wherein each symbol is representative of an action involving physical exertion and skill;

generating a sequence of symbolic descriptions wherein each symbolic description is a representation of a discrete sub-event of the live event and includes at least one symbol from said set of symbols, wherein an indicated status of the event may be affected by an action described by the symbol;

creating a database file corresponding to the event;

updating said database file with a generated sequence of symbolic descriptions;

broadcasting said symbolic descriptions after updating said database file;

receiving the broadcasted symbolic descriptions at the viewer computer;

storing the received symbolic descriptions;

generating a computer simulation of the live event at the viewer computer using said received symbolic descriptions by calculating new status information from a combination of the received symbolic descriptions and previously calculated status information in accordance with the rules that govern the event.

10. The method of claim 9 wherein each sub-event comprises a plurality of actions and each action has associated therewith at least one parameter and wherein each symbolic description includes a separate value for each parameter associated with a given action.

11. The method of claim 9 wherein said symbolic description is generated on an observing computer and said data base file is located at a location distinct from the observing computer.

12. The method of claim 11 wherein the viewer computer, at a location distinct from that of the live event is also at a location distinct from that of said database file and further includes a viewer event file, which is periodically updated with information from said database file.
