Abstract:
A method for interactively changing an EEPROM data of a video cassette tape recorder, said method comprising the steps of:(i) displaying a service menu picture of a service mode on a television screen if the service mode is selected in response to a first remote controller input;(ii) displaying an EEPROM data change menu picture on the television screen if an EEPROM data change mode in the service menu picture is selected in response to a second remote controller input;(iii) 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 controller input; and(iv) 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 controller 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 of recorded and reproduced signals, a visibility factor of the reproduced signal, an image equalization characteristic and a record level.
