Method and apparatus for controlling a device on a network

摘要

A system for controlling a device using a computer coupled to the device through a communication medium. The device contains an program code capable of generating control signals used by the device. A message is broadcast from the device across the communication medium indicating the existence of the device on the communication medium. The computer requests transmission of the device program code across the communication medium. The device then transmits the program code from the device to the computer. The program code is executed by the computer to generate control signals for controlling the device.
