SCALABLE VIDEO BROADCAST ON A WIRELESS NETWORK FOR USING MULTIPLE TRANSMISSION RATE PHYSICAL LAYER ON 802.11 WIRELESS LAN MEDIA ACCESS CONTROL LAYER

摘要

PURPOSE: A scalable video broadcast on a wireless network for using multiple transmission rate physical layer is provided to compress a broadcast target video in H.264/SVC codec and to differentiate transmission rate according to the importance of video data.;CONSTITUTION: A transmission rate(101) is 6, 9, 12, 18, 24, 36, 48 or 54 Mbps when H.264/SVC(Scalable Video Coding) video data is broadcasted through a wireless terminal. A distance(102) implies the distance of data about the wireless terminal. When H.264/SVC codec video is classified from L0 to Ln by NAL(Network Abstract Layer), the L0 is transmitted to the wireless terminal.;COPYRIGHT KIPO 2012
