Mobile IPTV can be watched on a wise phone that was intelligent or 3G mobile phone, like Samsung SCH or the LG Vu. It is VCAST IPTV and it’s AT and T Mobile IPTV. The two AT and T and Verizon Mobile IPTV use Medial technology from Qualcomm to broadcast the VHF digital IPTV signals to the cellular phones. Mobile IPTV service from various carrier packages different set of IPTV stations in its air. Mobile IPTV service does not use the phone system to transmit the IPTV signals. It uses another system transmit to distribute and broadcast the IPTV signals. It uses the cell phone network to give the IPTV service provider to interactivity and user consent. Since the 3G cell phone system from AT and T and Verizon are equally able to carry IP traffic, it appears to be evident that the easiest implementation for mobile IPTV is using IPTV. A fantastic example is AT and T already using IPTV in its U-verse support.
To understand why IPTV does not use IPTV, the cell phone network’s nature has to be explained. The current 3G cell phone network are made to carry uncast traffic only point to point link should be set between the consumer and the Media server for the network to deliver the iptv traffic to your cell phone. Since IPTV is a broadcast service that is a point to multipoint connection is necessary for mobile IPTV services. To execute point to multipoint connection, the cell phone network should set up an IP link between the Media server and every mobile user receiving the broadcast concurrently. These many connections will easily overrun the capacity of the cell phone system and blocks other voice and data traffic that should use the network.
For IPTV, the IP multicast feature has to be implemented on the cell phone network. Multicasting is the method of transmitting a video signal simultaneously. All viewers get the exact same signal at exactly the exact same time but there are no separate streams for each receiver. IP multicast is utilized in the delivery of broadcast IPTV services. It reduces the amount of bandwidth necessary to transmit high quality IPTV content across a network. Although the current 3G network from Verizon and AT and T does not have IP multicast, On the other hand the 3G network update from both carriers might include the IP multicast feature. For AT and T Wireless, the network upgrade will be HSPA which affirms the MBMS feature. For Verizon Wireless, the update will be EVDO Rev A that supports the BCMCS feature. The future mobile IPTV support from Verizon and both AT and T Wireless can use IPTV implementation.
