1. A method for broadcasting information about a live event that is constituted by a plurality of subevents, each subevent including at least one action, comprising the steps of:
- producing a first information signal comprising an audio description of the event;
producing a second information signal, said second information signal including a sequence of symbolic representations for each subevent of the event, each sequence including a value for at least one status variable that defines the status of the event at a particular time in relation to the subevent represented by that sequence, said second information signal comprising a signal from which a computer simulation of the event described by the first information signal can be produced;
producing a broadcast signal by combining said first and second second information signals;
transmitting said broadcast signal from a first location;
receiving said broadcast signal at a second location;
separating said broadcast signal into said first and second information signals;
analyzing said second information signal using pattern-matching techniques to detect subevents and status information of interest;
selectively producing an audio representation of the event using said first information based on the detection of subevents and status information of interest by said step of analyzing.

Abstract
A live event may be broadcast with a combination signal that includes a computer coded description of subevents that constitute the event and an audio or visual signal. The viewer'"'"'s computer then provides an indication to the viewer of the occurrence of subevents of interest and allows the viewer of the event to search for such subevents in a recording of the event.

10. In a system for broadcasting information about an event, including descriptions of subevents and a status of the event associated with each subevent, a method for detecting subevents of interest comprising the steps of:
-
entering codes in a first computer, said codes defining information of interest; generating a pattern from said codes; entering subevent descriptors in a second computer, said subevent descriptors describing the subevents and status of the event; transmitting said subevent descriptors to said first computer; comparing said codes of said pattern to said subevent descriptors at said first computer; and when said step of comparing detects a subevent descriptor that matches one of said codes, producing a signal indicating such a match. - View Dependent Claims (11, 12, 13, 14, 15, 16)
