1. A method for annotating a delayed feed of a sporting activity with tracking information determined within a tracking apparatus for a plurality of objects, comprising:
- determining when continuous location tracking information for a primary one of the plurality of objects is not available;
when, for a period when the continuous location tracking information for the primary object is not available and based upon a highest probability defined within one or more predetermined scenarios of the sporting activity, speculatively associating the primary object with a first one of two secondary ones of the plurality of objects that are proximate a last location of the primary object;
when the continuous location tracking information for the primary object becomes available after the period, receiving an updated location for the primary object and evaluating correctness of the speculative association of the primary object with the first secondary object based upon the updated location, to produce a non-speculative association of the primary object with one of the secondary objects; and
outputting the delayed feed with the tracking information for the first object based upon tracking information of the non-speculatively associated one of the secondary objects during the period when the continuous location tracking information is not available.

Abstract
Systems and methods track a first object when continuous tracking information for the first object is not available. The systems and methods detect when the tracking information for the first object is not available. A last time of a last determined location of the first object is determined and a second object closest to the last determined location at the last time is determined. The location of the first object is associated with a location of the second object if tracking information for the first object is not available.

9. An associative tracking apparatus for annotating a delayed feed of a sporting activity with tracking information determined within a tracking apparatus for a plurality of objects, comprising:
-
a tracking reliability monitor for determining when continuous location tracking information for a primary one of the plurality of objects is not available; an associative tracker for (a) speculatively associating, when notified by the tracking reliability monitor that continuous location tracking information for the primary object is not available and based upon a highest probability defined within one or more predetermined scenarios of the sporting activity, the primary object with a first one of two secondary ones of the plurality of objects that are proximate a last location of the primary object, (b) when the continuous location tracking information for the primary object becomes available, receiving an updated location for the primary object and evaluating correctness of the speculative association of the primary object with the first secondary object based upon the updated location, to produce a non-speculative association of the primary object with one of the secondary objects; and
(c) producing the tracking information with tracking information for the first object, during period when the continuous location tracking information is not available, being based upon tracking information of the non-speculatively associated one of the secondary objects; andan output generator for outputting the tracking information with the delayed feed. - View Dependent Claims (10, 11, 12, 13, 14)
