US Patent 7339470 Digital integrated motion system

A process that records, transmits and analyzes moment-to-moment data of objects of interest at an event for the production of a digital representation of the event. This representation is the result of a short-range radiolocation system used for tracking objects. Computing systems re-create timed sequences of event and broadcasts the digital representation to both local interactive PDA's and to internet virtual casts. Four or more receivers are situated so as to cover the entire area of the event. Transmitter tags are placed on all objects (e.g., players, ball etc). The processor receives the data and compiles it for digital recreation and transmission to the aforementioned destination devices.
