This document provides the necessary specifications to construct a Data Return Link (DRL) system for automatic transmitter control (ATPC) applications. This document further specifies the mechanisms necessary for basic identification and power control of TV Broadcast Auxiliary Service (BAS) transmitters, in either an automatic or manual mode. The initial, and default, operating mode is known as the “Beacon Mode.” An optional, lower-power operating mode, known as the “Transport Mode,” may be used if the RF environment permits. Both modes include the necessary mechanisms to permit the carriage of specialized private data (e.g., camera control information and operator communications) that is applicable to remote field production.
