A ceiling suction type digital television device includes a wireless signal received through an aerial, whereupon the wireless signal having a carrier wave is converted into a general signal by means of a demodulator decoding unit and transmitted to a sound processing unit, a video signal processing unit and a sub-title processing unit, whereat encoding and modulation of each respective signal arriving at each of the processing units is carried out, whereafter the signals are sent to an images and sounds output unit. Signal communication coordination is implemented by means of a central processing unit. Furthermore, a video signal circuit board is connected to a connecting terminal of a display circuit board through a connecting cable, further connected to a connector of a ceiling suction type display unit through a connecting cable, whereat the images, sounds and video are televised through a liquid crystal display.
