Abstract: A network device for A/V products having IR remote control has first and second network transmitters connected to a common network media to transmit network packages to each other. The first network transmitter is connected to one A/V terminal and converts IR signals to command packages. The second network transmitter is connected to at least one A/V player and converts command packages to IR signals corresponding to the A/V player. When an IR signal from a IR remote control is sent to the first network transmitter, the second network transmitter will receive the command packages from the first network transmitter and output the same IR signal to an A/V player to control functions of the A/V player. Since network media are being built into houses as the advent of digital home era, the present invention easily integrates all A/V products to make remote control more convenient.
