A program guide offerer of analog and digital broadcasting system and a method for offer using the same

PURPOSE: An apparatus and a method for providing analog and digital broadcasting program guides is provided to display both analog and digital broadcasting program guides, having their respective transmission formats, to users through a single electronic program guide screen at the same time. CONSTITUTION: A ground wave tuner(32), receiving a digital ground wave broadcasting signal through a ground wave antenna(31), synchronizes to a channel and outputs a transport stream. A satellite tuner(34), receiving a satellite broadcasting signal through the ground wave antenna(31), synchornizes a repeater signal of a desired channel among many repeaters and outputs a transport stream. A host processor(36) constructs a database by analyzing extrinsic information in the bit streams outputted from the ground wave tuner(32) and the satellite tuner(34), and outputs a control signal if a channel is inputted through a remote control(35) by a user. A multiplexer(37) selectively outputs either of the bit streams according to a control signal outputted from the host processor(36). A transport demultiplexer(38) selects and outputs packets for a desired channel in the selected bit stream. A video decoder(39) comprising an OSD processing part(391) reproduces a video signal by receiving and decoding a video packet among the packets outputted from the transport demultiplexer(38). An audio decoder(40) receives and decodes an audio packet among the packets outputted from the transport demultiplexer(38) and regenerates an audio signal.
