Mobile TV service from different service provider package various collection of TV channels in its program (in the series of 10 to 12 TELEVISION networks in a basic bundle).
Mobile TV service does not utilize the cellphone network to send the TV signals. Instead, it uses a separate network to distribute, transfer as well as broadcast the TV signals to the smart phones. It just utilizes the cellphone network to offer interactivity and individual consent with the TV provider. Since the 3G cellphone network from AT&T as well as Verizon are both qualified to lug IP website traffic, it seems to be obvious that the simplest execution for mobile TELEVISION is using IPTV. A good example is AT&T already using IPTV in its U-verse service (internet, phone and also TELEVISION).
To comprehend why mobile TV does not use IPTV, the unicast nature of the smart phone network needs to be explained. The existing 3G (UMTS, EVDO) cellphone network are created to bring unicast website traffic only, i.e. indicate factor link requires to be develop in between the user as well as the Media web server in order for the network to deliver the TV traffic to the mobile phone. Because TV is a broadcast service, i.e. an indicate multipoint link is needed for mobile TELEVISION service. To execute point to multipoint connection, the mobile phone network needs to establish an IP link in between the Media server and each mobile individual receiving the program simultaneously. These several connections will conveniently overwhelm the capacity of the cellphone network and also blocks other voice and data website traffic that requires to utilize the network.
For mobile TELEVISION to make use of IPTV, the IP multicast attribute needs to be implemented on the mobile phone network. Multicasting is the technique of transmitting a single video clip signal simultaneously to multiple end customers. All visitors get the very same signal at the very same time but there are no different streams (links) for each recipient. IP multicast is extensively utilized in the distribution of broadcast TELEVISION services over IP networks. It considerably lowers the quantity of transmission capacity needed to send premium quality IPTV web content throughout a network. This is due to the fact that only a single duplicate of every video clip stream needs to be sent to a router, which subsequently makes a copy of that stream for the asking for gadgets. Not just does multicast lower the bandwidth demands of the network but the processing power of the Media server can also be kept relatively low due to the fact that it only sends one duplicate of an IPTV stream at once.
Although the existing 3G mobile network from AT&T as well as Verizon does not have IP multicast, nevertheless, the following 3G mobile network upgrade iptv server from both carriers might consist of the IP multicast feature. For AT&T Wireless, the next network upgrade will certainly be HSPA (High Speed Packet Accessibility) which sustains the MBMS (Multimedia Program Multicast Provider) attribute. For Verizon Wireless, the following upgrade will certainly be EVDO Rev A which sustains the BCMCS (Broadcast and also Multicast Providers) feature. Therefore, the future mobile TV solution from both AT&T Wireless and Verizon Wireless may utilize IPTV execution.
