Mobile TELEVISION can be seen on a smart or 3G smart phone, such as the LG Vu or Samsung SCH u620 smart phone. Both AT&T Wireless and Verizon Wireless offer mobile TELEVISION solutions. For Verizon, it is VCAST TELEVISION and for AT&T, it is AT&T Mobile TELEVISION. Both AT&T and Verizon Mobile TELEVISION use MediaFLO innovations from Qualcomm to relay the VHF digital TELEVISION signals to the mobile phones. Mobile TV solution from various provider bundle different set of TELEVISION channels in its program in the variety of 10 to 12 TV networks in a fundamental bundle. Mobile TELEVISION service does not utilize the smart phone network to transfer the TV signals. Rather, it uses a different network to distribute, send and transmit the TV signals to the cell phones. It only makes use of the smart phone network to provide interactivity and customer authorization with the TV provider. Because the 3G smart phone network from AT&T and also Verizon are both qualified to carry IP web traffic, it seems to be noticeable that the most basic execution for mobile TV is utilizing IPTV.
To understand why mobile TELEVISION does not make use of IPTV, the uncast nature of the cell phone network has to be discussed. The existing 3G (UMTS, EVDO) smart phone network are developed to carry uncast website traffic just, i.e. point to point link needs to be establish between the user and the Media server in order for the network to supply the TV website traffic to the mobile phone. Since TV is a program solution, i.e. an indicate multipoint link is required for mobile TV solution. To apply indicate multipoint link, the cell phone network needs to set up an IP link between the Media web server and each mobile individual obtaining the broadcast concurrently. These several links will conveniently overrun the capability of the mobile phone network and also obstructs other voice and information traffic that should utilize the network.
For mobile TV to use iptv providers, the IP multicast feature needs to be implemented on the cell phone network. Multicasting is the strategy of transmitting a solitary video clip signal simultaneously to numerous end customers. All customers get the same signal at the same time however there are no different streams (connections) for each and every recipient. IP multicast is widely used in the distribution of program TV services over IP networks. It considerably minimizes the amount of transmission capacity called for to transfer excellent quality IPTV content across a network. This is due to the fact that only a solitary duplicate of every video clip stream should be sent out to a router, which then makes a copy of that stream for the requesting devices. Not just does multicast lower the transmission capacity demands of the network yet the handling power of the Media web server could additionally be kept reasonably low due to the fact that it just transmits one duplicate of an IPTV stream at a time.
