12 Why IPTV over WiMAX? The features of the WiMAX is multicast capability. Increase the Number of Subscribers Scheduled Live Content and Quality Assurance. Mobility.

13 Challenge WiMAX Bandwidth. Instance Channel Change. Mobility. Jitter. Overhead. Transceiver Design. Power Consumption.

14 System Model

15 Protocol Stack

16 System Design （ 1 ） VLAN divided by IP address Multicast Group divided by VLAN and Channel Select one prefix group （ 225 ）： first byte Reserved ： second byte VLAN ： third byte Channel ： fourth byte

17 System Design （ 2 ） In the third byte, Define 255 is broadcast. WiMAX Quality of Service Setup

18 System Design （ 3 ） WiMAX Packet Identify Rule Service Class Creation Packet Identify Rule Service Flow Class Subscriber Station Class Relationship ： SS Class  SF Class  PIR Subscriber Station List
