Abstract:
A receiver having an analog video mode for receiving television signals analog-processed by a predetermined analog broadcasting method and a digital video mode for receiving television signals digitally processed by a predetermined format, comprising:a first input terminal for receiving a channel-demodulated analog television signal;a second input terminal for receiving a channel-decoded digital television signal;a generator for generating a mode selection signal which represents one of said analog video mode and said digital video mode;a memory for storing data during a process of source-decoding said channel-decoded digital television signal during a process of processing said channel-demodulated analog television signal;a microprocessor for writing/reading one of said digital television signal during said digital video mode and a digitized analog television signal during said analog video mode, to and from said memory according to said mode selection signal;analog processing means having an input terminal for receiving said channel-demodulated analog television signal, an input terminal for receiving the data read from said memory through said microprocessor, an output terminal for outputting the data to said microprocessor to store said data into said memory and an output terminal for outputting a processed analog television signal;digital processing means having an input terminal for receiving said channel-decoded digital television signal, input and output terminals connected to said microprocessor, and a terminal for outputting a digital video signal reconstructed from said channel-decoded digital television signal;switching means for selecting one of said reconstructed digital video signal and said processed analog television signal according to said mode selection signal; anddisplay controlling means for controlling the signal output from said switching means to display the signal on a display.
