Claim 0:
1. A computer program product for auto-focusing one or more cameras on selected persons in a venue, wherein the selected persons in the venue are performers of a performance occurring at the venue, the venue including a real-time location system (RTLS) having a plurality of RTLS tags and a RTLS receiver for locating a position of each of the RTLS tags in three-dimensional space, wherein each of the RTLS tags is worn by, or attached to, one of the performers, or is attached to an object that one of the performers is wearing, carrying, or holding, and each of the RTLS tags transmits a signal including a unique RTLS tag identifier that is received by the RTLS receiver, and wherein one or more databases stores (i) a plurality of scenes of the performance, (ii) the performer or performers who are active during the respective scenes, and (iii) the unique RTLS tag identifier associated with each performer, the computer program product comprising a computer readable medium tangibly embodying non-transitory computer-executable program instructions thereon that, when executed, cause one or more computing devices to:
(a) receive at a controller a signal indicating the scene that is currently being performed;
(b) identify, using the controller and the database of the performer or performers who are active during respective scenes, which performer or performers are active during the currently performed scene;
(c) identify, using the RTLS, the position of the RTLS tags in three-dimensional space in the venue of the performer or performers who are active during the currently performed scene by using (i) the signals transmitted from the RTLS tags and received by the RTLS receiver to calculate the position of the RTLS tags in three-dimensional space, and (ii) the database that stores the unique RTLS tag identifier associated with each performer,
wherein the identified positions of the RTLS tags in three-dimensional space in the venue are presumed to be the same positions as the performers associated with the respective RTLS tags; and

(d) auto-focus the one or more cameras on the identified positions of the RTLS tags in three-dimensional space in the venue during the currently performed scene, the one or more cameras thereby (i) outputting a video signal of an area that is in proximity of the identified RTLS tags which are presumed to include the performers in the venue who are active in the currently performed scene, and (ii) following the respective performers during any movement by the respective performers during the currently performed scene.
