A method for generating and processing universal input codes, for which a universal remote control protocol is applied, and an apparatus thereof are provided. The method includes the steps of (a) setting a type code for indicating the type of an input device, and universal input codes which are mapped with local input codes according to the type of the input devices; (b) forming a data format by adding the type code and universal input codes set in step (a) and operation parameters for operating the type code and universal input codes. According to the method and apparatus, by unifying diverse input devices, manufacturing costs and developing time can be reduced, and user convenience can be provided.
