APPARATUS AND A METHOD FOR CHANNEL SCANNING IN A SET-TOP-BOX, PARTICULARLY FOR PROVIDING VISUAL CHANNEL SEARCHING INFORMATION IN A SET-TOP BOX

摘要

PURPOSE: An apparatus and a method for channel scanning in a set-top-box are provided to efficiently search a channel based on user-preferred channel information by performing channel searching through a DVR(Digital Video Recorder) function in a set-top box.;CONSTITUTION: A demultiplexer(104) separates a data stream, an image signal and an audio signal from a demodulated broadcasting signal. A recording unit(106) converts the signals and the data stream into a recordable signal for a data storage unit(110). Whenever a user selects each channel, a scanning management unit(108) generates scanning data. A reproduction unit(112) provides the recorded broadcasting data of the data storage unit or scanning data to an output unit(114).;COPYRIGHT KIPO 2010
