Abstract: The first triax camera (the PC-100) was introduced to the broadcast industry in 1969. It was designed to solve a number of problems associated with conventional multicore cable cameras. A second-generation triax camera, the LDK-5, was introduced in 1975. It offered additional capabilities and was selected by ABC for three mobile units. A narrow-bandwidth digital control channel is used for microwave applications. The microwave configuration was ruled out, however, for the 1980 Winter Olympics, and a triax repeater was designed and used for this location. The compact, lightweight EFP LDK-14 camera was designed for easy conversion to triax. A major design consideration for a triax system is the choice of whether to transmit encoded video or RGB video from the camera head to the camera control unit (CCU). Although the majority of triax cameras are presently used for field applications, changes in camera design now offer the prospect of cost-effective triax studio cameras.
