Abstract: A data recording and playback system and method with a memory device adapted to receive and temporarily store input signal data as data frames with time stamps, the memory device having addresses associated thereto, and a circular storage buffer having a memory mapped file with same address space as the memory device for storing the input signal data. In one embodiment, an event controller provides an event signal associated to time of an event, and an event processor is provided that copies plurality of data frames stored in the circular storage buffer that have time stamps proximate to the time of the event. Another embodiment is adapted to allow playback of stored input signal data from the circular storage buffer without interrupting simultaneous recording of new input signal data into the circular storage buffer.

Abstract: A system for monitoring a sporting event includes devices for monitoring characteristics of the event and collecting monitored data. Devices address different aspects of the event and monitor and collect real-time data. The devices process the data into digitized frames, and a digital storage device receives and stores the frames in a random access storage buffer as time-stamped digitized data frames with unique addresses. The storage device is capable of both time-shifting and relational association. The system includes a controller and devices for monitoring and extracting a digitized data frame according to a predetermined criterion. A viewer communicates with the storage device and controller and selects, manipulates, and extracts the digitized data frame. The system records and plays back the monitored data using a circular storage buffer with a memory mapped file and allows playback of stored data without interrupting simultaneous recording of new input data.
