Abstract

PURPOSE: A digital corresponding analog television receiver card is provided which a system upgrade to support digital broadcasting is easy with low cost. CONSTITUTION: A tuner(115) outputs a tuned signal to a specific channel by receiving a broadcast signal, and outputs an analog broadcast signal to the first tuning port if the specific channel is an analog broadcast channel, and outputs a digital broadcast signal to the second tuning port if the specific channel is a digital broadcast channel. An analog decoder(114) provides the first digital A/V data corresponding to the tuned analog broadcast channel by converting the analog broadcast signal from the first tuning port into digital data. An extended interface includes the first extension port to provide the digital broadcast signal to an external digital extension card, and the second extension port to provide a chip set control signal as to the external digital extension card to the external digital extension card, and the third extension port to receive the second digital A/V data being output from the external extension card in correspondence to the digital broadcast signal. And a digital integration connection part receives the first and the second digital A/V data and then provides them to a computer system through digital connection and provides the chip set control signal as to the external digital extension card.
