Efficient MAC-layer packet fragmentation method and system having a priority queue for real-time video streaming is provided. Efficient MAC layer packet fragmentation method having a priority queue for a real-time video streaming proposed by the present invention is TS parser (TS Parser) an output classifying IP packets into TS packets and non -TS packet, the priority of each TS packet ranking analyzing the information bit map, a packet segmentation (packet Fragmenter) the prioritizing the short TS packet size by using the channel state information in the bitmap rate adaptation module based on the information, and the determined fragments provided by the TS parser TS packet order of the short TS packet by applying one of at the IP header, UDP header, RTP header, the steps and the order storage unit which divides the TS packet into a plurality of short TS packets, each fragment (order Preserver) TS packets according to the size a comprises the steps of maintenance and management.
