The invention discloses a method and a system for reporting infrared remote controller events. The method comprises steps of A, when an intelligent television receives a key event of an infrared remote controller, entering an infrared driving service-interrupting program, reading a register to obtain infrared carrier wave information, determining whether or not the infrared carrier wave is a wave head, and if so, entering a step B; and B, starting a timer, entering an overtime interruption function when the timer exits due to overtime, determining the value of a flag bit, if the value of the flag is a first flag value indicating that the key event of the remote controller is not analyzed, regarding the current key event as an unknown key event, reporting a key value of the current key event to an upper level space, and the upper level space broadcasting an appointed message to inform an upper level application for performing corresponding logic motions. The invention modifies television core infrared driving, so that the television can receive and analyze key information of equipment such as a set top box, thereby informing the upper level application for performing related logic operation.
