Mobile IPTV services over wireless cellular networks become more and more popular, owing to the significant growth in access\nbandwidth of wireless cellular networks such as 3G/4G andWiMAX.However, the spectrumresources of wireless cellular networks\nis rare. How to enhance the spectral efficiency of mobile networks becomes an important issue. Unicast, broadcast, and multicast\nare the most important transport schemes for offering mobile IPTV services over wireless cellular networks. Therefore, bandwidth\nusages and blocking rates of unicast, broadcast, andmulticast IPTV services were analyzed and compared in this paper. Simulations\nwere also conducted to validate the analytical results. Numerical results demonstrate that the presented analysis is correct, and\nmulticast scheme achieves the best bandwidth usage and blocking rate performance, relative to the other two schemes.
