Abstract

An exemplary method and system for evaluating media-playing sets evaluates the likelihood of a selected performance condition occurring in a subject set including based on source data automatically collected from a sample group of the sets, systematic analysis of this data to form a decision tree model revealing prescribed values for characteristic input parameters that are determined to best relate to the condition, and automated comparison of the respective parameter values of the subject set to these prescribed values in order to screen each subject set for the likelihood of the condition occurring within a specified timeframe, which screening can be repeated for different conditions and timeframes using different decision tree models.

Claims

1. A method for evaluating media-playing sets, each set being characterized by a plurality of input parameters having respective values, said method comprising:

(a) collecting data identifying for each member of a sample group of said sets whether a selected performance condition has occurred;

(b) analyzing said data so as to relate said selected performance condition to characteristic ones of said input parameters and, also, to prescribed values of said characteristic ones of said input parameters; and

(c) evaluating the likelihood of said selected performance condition occurring in a subject set by detecting the respective values of at least those ones of said input parameters of said subject set corresponding to said characteristic ones and comparing said respective values to said prescribed values.

2. The method of claim 1 wherein said analyzing step includes developing a diagnostic algorithm expressible as a decision tree, said characteristic ones of said input parameters being represented by nodes on said tree and said prescribed values of said characteristic ones of said input parameters being represented by at least one branch extending from each node.

3. The method of claim 2 wherein said decision tree has a root node and branches leading away to other nodes, said characteristic ones of said input parameters being ranked beginning at said root node and continuing along said branches in order from that showing the strongest correlation with said selected performance condition to that showing the weakest.

4. The method of claim 1 further including adapting said method to a plurality of media-playing sets dispersed over locations geographically remote from each other by providing a support site that communicates through a network connection with each media-playing set and remotely detecting said respective values of each set from said support site.

5. The method of claim 4 including regularly detecting said respective values of each set from said support site to identify changes in said respective values signaling an increased likelihood of said performance condition occurring in at least one of said sets.

6. The method of claim 5 further including remotely alerting the user of said at least one of said sets where said increased likelihood of said performance condition occurring is deemed undesirable.

7. The method of claim 4 wherein said analyzing step includes developing a diagnostic algorithm expressible as a decision tree for use in said comparing step and updating said algorithm by modifying said decision tree whenever said support site detects said selected performance condition has occurred in one of said plurality of media-playing sets.

8. A system for evaluating media-playing sets, each set being characterized by a plurality of input parameters having respective values, said system comprising:

(a) an incident database for recording data identifying for each member of a sample group of said sets whether a selected performance condition has occurred;

(b) an analyzer for analyzing said data and relating said selected performance condition to characteristic ones of said input parameters and, in particular, to prescribed values of said characteristic ones of said input parameters; and

(c) a diagnostic tool for evaluating the likelihood of said selected performance condition occurring in a subject one of said sets including by obtaining the respective values of at least those ones of said input parameters of said subject set corresponding to said characteristic ones and comparing said respective values to said prescribed values.

9. The system of claim 8 wherein said analyzer, in performing the analyzing operation, develops a diagnostic algorithm expressible as a decision tree, said characteristic ones of said input parameters being represented by nodes on said tree and said prescribed values of said characteristic ones of said input parameters being represented by at least one branch extending from each node.

10. The system of claim 9 wherein said decision tree has a root node and branches leading away to other nodes, said characteristic ones of said input parameters being ranked beginning at said root node and continuing along said branches in order from that showing the strongest correlation with said selected performance condition to that showing the weakest.

11. The system of claim 8 further including a support site, a network adapter in each set enabling network connection to said support site despite a plurality of said sets being geographically dispersed remotely from each other, and a detector at said site for remotely detecting status information about each set including the respective values of said input parameters of each set.

12. The system of claim 11 wherein said detector regularly detects said respective values of each set from said support site to identify changes in said respective values signaling an increased likelihood of said performance condition occurring in at least one of said sets.

13. The system of claim 12 further including an alarm at said site for remotely alerting the user of said at least one of said sets where said increased likelihood of said performance condition occurring is deemed undesirable.

14. The system of claim 11 wherein said analyzer develops a diagnostic algorithm expressible as a decision tree for use by said diagnostic tool in said comparing operation and said algorithm is updated by said analyzer modifying said decision tree whenever said support site detects said selected performance condition has occurred in one of said plurality of media-playing sets.
