Abstract

A method and apparatus for controlling the operation of electronic entertainment devices in an entertainment system is described herein. A hardware system is coupled to a plurality of electronic entertainment devices to receive and transmit audio-video signals Transmit logic is coupled through a digital computer interface, preferably a SCSI interface, to the hardware system. The transmit logic has a plurality of ports and a memory associated with each port for storing control data sequences for each respective port. Each portis independently addressable by the hardware system A plurality of transmitters, each coupled to a respective one of the transmit logic ports transmits the respective store; control data sequences to respective ones of the electronic devices. In a preferred embodiment, the hardware system has a microprocessor, user interface and system memory and the transmitters are infrared light transmitters, one of which is a blaster transmitter for transmitting control data sequences simultaneously in multiple directions.
