When the mute function is selected, the present invention automatically outputs the closed caption screen of the channel being watched, so that the caption screen can be checked through the caption even when the audio output cannot be heard. A satellite broadcasting receiving system having a providing function, comprising: a satellite broadcasting receiving system having a key input unit for a user command and a control unit for controlling the operation of the entire apparatus according to a user command input through the key input unit. A BS tuner that tunes a channel selected by a user from a satellite broadcast signal received by the user; and a QPSK demodulator for demodulating the original digital data stream from a quadrature phase modulated (QPSK) broadcast signal output from the BS tuner; From the data stream packetized according to a predetermined control signal from the controller A decoder unit which separates the data of each area and restores the original signal from the video and audio signals received in a compressed form, and the hue and luminance for image reproduction based on the video signal restored and output by the decoder unit. The image processor outputs a signal, the CRT driver for driving the CRT according to the color tone and luminance signal output from the image processor, and the audio signal output from the decoder according to a control command from the controller. And a voice processing unit configured to execute a voice processing unit. The control unit controls the voice processing unit to mute the audio output when the voice muting function is selected through a key input unit, and to decode the caption screen for the viewing channel through the decoder unit. It is characterized by controlling.
