Automatically fine tuned pictures and sounds can be obtained from a novel color television system having a video/audio signal adjusting circuit, a remote controller operable for generating a program mode selection signal, a memory having a plurality of memory locations for storing operating parameter data for the video and the audio processing circuit corresponding to program modes, a microprocessor responsive to the program mode selection signal for receiving the operating parameter data corresponding thereto and for generating an audio control signal and a video control signal, a video signal adjusting circuit responsive to the video control signal for adjusting the video signal to have a video characteristic corresponding to the program mode selection signal, and an audio signal adjusting circuit responsive to the audio control signal for adjusting the audio signal to have a frequency band characteristic corresponding to the program mode selection signal.

DETAILED DESCRIPTION It is, therefore, an object of the invention to provide a color television system having a video/audio signal adjusting apparatus which is capable of providing a finely tuned picture and sound for each type of broadcast programs.
Another object of the invention is to provide a color television system having a video/audio signal adjusting apparatus which is capable of providing a convenient adjustment of the video and the audio signal processing circuits contained therein for each type of broadcast programs.
In accordance with one embodiment of the present invention, there is provided a color television system having a video and an audio processing circuits for receiving and reproducing a broadcast program having an audio and a video signals, which comprises: a remote controller operable for generating a program mode selection signal; a memory having a plurality of memory locations for storing predetermined operating parameter data for the video and the audio processing circuits corresponding to the program mode; a microprocessor responsive to the program mode selection signal for receiving the operating parameter data corresponding thereto and for generating an audio and a video control signals; a video signal adjust circuit responsive to the video control signal for adjusting the received video signal to have a video characteristic corresponding to the program mode selection signal; and an audio signal adjusting circuit responsive to the audio control signal for adjusting the received audio signal to have a frequency characteristic corresponding to the program mode selection signal.
In accordance with another embodiment of the present invention, the remote controller includes a program mode selection key and a plurality of digit keys and the television system further comprises an OSD(on-screen display) character generator responsive to the operation of the program mode selection key for displaying a numbered list of the program modes and for enabling the digit keys to select the program modes
