PURPOSE: A multi radio signal transmission system for a smart device and a computer is provided to transmit a control signal and a data signal on a real time basis through a transmitter/receiver module. CONSTITUTION: A connection unit (100) transmits or receives an ultra-wideband signal using a second transmitter/receiver module (210) built in a video output device (200). The connection unit converts the ultra-wideband signal into either a recognizable control signal or a recognizable data signal and inputs the converted signal into a mobile device (10) so that the mobile device can process the signal. The video output device includes a second power supply unit (220), the second transmitter/receiver module (210), a second control unit (230), a display unit (240), and a sound output unit (250). A video signal processing unit (231) analyzes a video control signal, converts the signal at maximum resolution provided, and transmits the signal to the display unit. As a first transmitter/receiver module (110) and the second transmitter/receiver module uses ultra-wideband telecommunication, high-definition video data can be transmitted and received at a high transmission speed.
