ABSTRACT:
A real-time compensation apparatus and method for a digital TV that can update the present time without addition of a non-volatile memory or RTC. The apparatus includes a first control section for controlling a power supply of a system, updating a time by dividing a system clock, and outputting a reserved recording signal according to comparison result of the present time with a user's reserved recording time; and a second control section for transmitting the reserved recording information stored in a flash memory and the present time to the first control section if the power supply is off, and outputting a load control signal so that output of video and audio is performed according to the signal outputted from the first control section according to the user's reserved recording time. The apparatus and method can reduce the loss of the real-time function such as the user's reserved recording by updating the present time without addition of any separate device even if the power supply is resumed due to the power failure and so on, and thus improve the reliability of the product.
