… applications such as digital TV or video conference,this paper considers real time video multicast for users with diverse screen sizes.By transmitting a video over a wireless channel accessed by the multiple users,the video can be transmitted to the all users.However,in order to gain from multicasting,quality of the channel has to be sufficiently high for the all users,and probability that such channel happens become lower as the number of the users grows.In this paper,orthogonal frequency division multiple access (OFDMA) scheme is considered to solve …

… To solve this problem, Non-ordered Block Transfer (NBT) has been proposed as an efficient transfer system for large-capacity stored files using asynchronous transfer mode (ATM) multicast. … In this paper, to solve this problem we propose an NBT protocol using XCAST (NBT on XCAST), which is proposed as a multicast scheme. …
