Systems and methods for communicating real-time sporting event and participant announcement information received from a sport timing system (STS). The system comprising an announcement interface system having a processor, a memory, a first data interface communicating over the a stateless packet data communication network with the sport timing system, and a second interface communicating with an announcement system. The first data interface receives a multicast datagram ANNC message including an identification of the sport timing system and participant data including a participant identifier for uniquely identifying each participant in the sporting event and participant timing data. The announcement interface system formats the received portion of the participant data into an announcement system message and transmitting the announcement system message including the participant data, the participant identifier and participant timing data.
