A central controller and a number of image projection lighting devices ("IPLD"), a type of multiparameter light, are interconnected by an enhanced performance communications path that is capable of simultaneously carrying different digital signals on various bidirectional channels, such as various content signals, including continuous video and/or audio, in digital form on respective content transfer channels, a command signal on a control channel, and a control or content signal in digital form on an auxiliary channel. In accordance with commands transmitted from the central controller over the control channel, content signals may be sent from any of the IPLDs to any other of the IPLDs, or from the central controller to any of the IPLDs, or from any of the IPLDs to the central controller. The IPLDs have respective unique device addresses, and the control channel, the auxiliary channel, and the content transfer channels also have respective unique channel addresses.
