APPARATUS AND METHOD FOR RECEIVING A BROADCASTING DATA IN HANDHELD DIGITAL BROADCASTING SYSTEM

摘要

A broadcasting data receiving device in a portable digital broadcasting system and a method are provided to shorten delay time when requesting channel conversion in a receiver of the portable digital broadcasting system, and to decrease power consumption of the receiver. An RF(Radio Frequency) receiver(702) receives a broadcasting signal. A baseband processor(704) demodulates the received broadcasting signal. An application processor(708) outputs a channel conversion signal if a broadcasting-related key input signal for channel conversion is received, and outputs demodulated broadcasting data through audio/video decoding. If the channel conversion signal is received, a time slicing controller(706a) controls so that the receiver(702) and the processor(704) receive and demodulate the received broadcasting signal irrespective of time slicing. A memory(710) stores the demodulated broadcasting data.
