Digital cable broadcast processing apparatus and method thereof
Abstract:
A digital cable broadcast processing apparatus and a method thereof. A power supply supplies power, and an out-of-band (OOB) receiver receives additional OOB information from a transmission system. A cable card to descramble the received OOB information is mounted in an interface, and a controller controls the power supply in accordance with the presence and absence of the cable card, and accordingly controls the power supply to the OOB receiver. Whether or not the cable card is mounted is determined, and power is cut off or supplied in accordance with the result of the determination. As a result, unnecessary power consumption can be prevented when the cable card is not mounted.
