Both AT&T and also Verizon Mobile TV use Medial technologies from Qualcomm to transmit the VHF 719 MHz Center frequency electronic TV signals to the mobile phones. Mobile TV service from various service provider bundle various set of TV networks in its broadcast in the array of 10 to 12 TV channels in a fundamental package. Mobile TV solution does not utilize the mobile phone network to transfer the TV signals. Rather, it uses a different network to distribute, transfer and broadcast the TV signals to the mobile phones. It utilizes the mobile phone network to offer interactivity and user consent with the TV provider. Because the 3G mobile phone network from AT&T and Verizon are both qualified to lug IP website traffic, it appears to be apparent that the simplest implementation for mobile TV is using IPTV. A good example is AT&T already using IPTV in its U-verse solution net, phone and TV.

To recognize why mobile TV does not utilize IPTV, the uncast nature of the mobile phone network requires to be explained. Since TV is a broadcast solution, i.e. a factor to multipoint connection is required for mobile TV service. For mobile TV to make use of IPTV, the IP multicast feature requires to be implemented on the smart phone network. Multicasting is the method of transmitting a solitary video clip signal concurrently to multiple end customers. All audiences receive the exact same signal at the same time yet there are no different streams links for every recipient. IP multicast is commonly utilized in the distribution of broadcast TV solutions over IP networks. It significantly decreases the amount of bandwidth required to send top quality IPTV web content across a network. This is since only a single copy of every video clip stream needs to be sent out to a router, which in turn makes a copy of that stream for the asking for devices. Not only does multicast decrease the bandwidth requirements of the network however the handling power of the Media server can additionally be kept reasonably low because it only transmits one copy of an IPTV stream each time

The current 3G mobile network from AT&T and Verizon does not have IP multicast, nonetheless, the following 3G mobile network upgrade from both carriers may consist of the IP multicast attribute. The future mobile TV solution from both AT&T Wireless and also Verizon Wireless may make use of IPTV implementation.
