Abstract:
A digital video receiving apparatus comprising:a tuner receiving a multiplexed signal and converting the multiplexed signal to a digital base band signal;a demodulator demodulating the digital base band signal provided from said tuner;a demultiplexer demultiplexing and outputting a bit stream including a video signal and an audio signal, a clock, and a stream identification signal for each of a plurality of channels according to a selection signal, when the multiplexed signal is an SDTV signal, and demultiplexing and outputting a bit stream including a video signal and an audio signal, a clock, and a stream identification signal for each of a plurality of partial pictures according to a selection signal, when the multiplexed signal is an HDTV signal;a video decoder decoding the video signals demultiplexed by said demultiplexer;an audio decoder decoding the audio signals demultiplexed by said demultiplexer;a display synthesizer synthesizing a plurality of the signals outputted from said video decoder and generating a video signal to display on one monitor;an audio selector selecting an audio signal outputted from said audio decoder; andan NTSC/decoder;wherein said tuner branches a received multiplexed signal into an analog base band signal and a digital base band signal,said NTSC/decoder decodes the analog base band signal provided from said tuner to generate a decoded analog video signal, andsaid display synthesizer synthesizes the analog video signal from said NTSC/decoder and the digital video signal from said video decoder and generates a video signal to display the analog video signal and the digital video signal on one monitor.
