  • Publication number: 20030131360
    Abstract: Disclosed are an interface system for stream source and display devices and an interfacing method thereof. The present invention includes a stream source device receiving analog/digital signals from external analog/digital equipments to generate a transmission packet stream corresponding to the analog/digital signal and transmitting the transmission packet stream by wireless and a display device receiving the transmission packet stream transmitted from the stream source device, the display device decoding the transmission packet stream to separate into a video signal and an audio signal to output respectively. Therefore, the present invention needs no additional cables to transmit various video, audio, and various control signals between the stream source and display devices, thereby enabling to overcome the problem of defiling the appearance of the cables exposed on the wall.
