A digital television receiving system includes a tuner, a demodulator, a known data detector, an equalizer, a transmission detector, and a block decoder. The door securing device includes a housing comprising a perimeter wall. In such structure, the motor and the control unit may be electrically coupled and decoupled, without the use of a special tool. The power supply provides the necessary energy and electric voltage level for the apparatus to operate and the solar conversion system provides a means for recharging andor maintaining a sufficient energy level within the power supply.
