Method and apparatus for interactively changing an EEPROM data of a video cassette tape recorder

A video cassette recorder, which comprises:

• a video processing section for processing a video signal according to recorded and reproduced characteristics;
• an EEPROM for storing characteristic values of the recorded and reproduced characteristics of the video processing section;
• an input means for inputting a remote control signal;
• an on-screen generating means for outputting an on-screen picture signal to a television after receiving an on-screen data;
• and
• a control section for displaying a service menu picture of a service mode on a television screen by the on-screen generating means if the service mode is selected in response to a first remote controller input, displaying an EEPROM data change menu picture on the television screen if an EEPROM data change mode in the in the service menu picture is selected in response to a second remote control input, displaying a characteristic value selection picture of a selected item on the television screen if the item in the EEPROM data change menu picture is selected in response to a third remote control input and changing an EEPROM data to a selected characteristic value if the characteristic value in the characteristic value selection picture is selected in response to a fourth remote control input,
• wherein the EEPROM data is a control characteristic of a recorded video signal or a reproduced video signal, the control characteristic being a pre-emphasis gain of the recorded signal, a ratio of a luminance signal to a noise therein of the recorded and reproduced signals, a visibility factor of the reproduced signal, an image equalization characteristic and a record level.
