    Abstract: A real time information display module and a method thereof are described. The real time information display module is coupled with a display device used for displaying TV signal. The real time information display module includes an information collection unit and an event detection unit. The information collection unit receives a setting instruction of an information category and collects share information corresponding to the information category according to a setting instruction. The event detecting module detects a TV event and an information event corresponding to the TV signal and the share information, respectively. When the TV event and information event exist at the same time, the real time information display module transmits a notification instruction to the display device. As a result, the display device retrieves and outputs the share information from the information collection module.
