Method and apparatus for generating and resetting melody for remote controller function keys

An apparatus for setting and generating a melody for a remote controller input signal, comprising:

• an on-screen display processing means for outputting an on-screen display control signal and displaying a melody set video on a screen of a display device in the case of a melody set mode corresponding to each inputted key press of a remote controller;
• a memory for storing melody information corresponding to each inputted key;
• a remote controller signal receiving means for receiving a remote controller signal corresponding to each operating input key of the remote controller;
• a control means for decoding an output signal from the remote controller signal receiving means, and in the case of the melody set mode corresponding to each inputted key, outputting the on-screen display control signal to the on-screen processing means, and when a specific key and a melody corresponding to the key from a melody set video displayed on the screen of the display device are selected, storing the selected key and melody information in the memory, and in the case of a function key input, decoding the output signal from the remote controller signal receiving means, reading the melody information corresponding to the inputted key and outputting the melody information;
• an audio generating means for outputting a melody signal which corresponds to the melody information of the control means;
• and
• an audio synthesizing means for synthesizing a reproduced audio signal and the output signal from the audio generating means, and outputting the synthesized signal to the speaker.

A method for generating a melody for a remote controller input signal, comprising:

• reception of an input signal by a remote controller signal receiving unit;
• determining whether the input signal corresponds to a remote controller signal;
• taking no further action if the input signal corresponds to a signal other than a remote controller signal;
• determining if the input signal corresponds to depression of a function key on a remote controller;
• searching for melody information in said remote controller input signal receiving unit corresponding to the function key depressed on a remote controller, the melody having been preset by a user according to said user's preference;
• generating a melody corresponding to the function key depressed, said melody not having been received along with any input signal;
• and
• generating an error sound or displaying an error caption in the case that the inputted key does not have a function.

A method for changing a pre-set melody corresponding to a function key on a remote controller, comprising:

• selecting a melody set mode for changing a melody corresponding to an inputted key to a different melody corresponding to the same inputted key based on a user preference;
• displaying a detailed list of choices of the melodies that are available to be selected for assignment to a function key on screen;
• designating a predetermined key and selecting a melody for assignment to the desired corresponding function key;
• and
• storing the newly assigned melody to correspond to the specific key selected and pressing a confirmation key to confirm the user selection.
