Mobile TELEVISION service from various carrier bundle various collection of TV channels in its program (in the range of 10 to 12 TELEVISION channels in a basic bundle).
Mobile TV service does not make use of the mobile phone network to transfer the TV signals. Instead, it utilizes a separate network to disperse, transmit and transmit the TELEVISION signals to the smart phones. It just utilizes the cellphone network to give interactivity as well as customer consent with the TV service provider. Since the 3G mobile phone network from AT&T as well as Verizon are both qualified to bring IP web traffic, it seems to be evident that the easiest implementation for mobile TELEVISION is using IPTV. A good example is AT&T currently utilizing IPTV in its U-verse service (net, phone as well as TELEVISION).
To comprehend why mobile TV does not use IPTV, the unicast nature of the smart phone network requires to be clarified. The current 3G (UMTS, EVDO) mobile phone network are created to lug unicast web traffic just, i.e. point to factor connection needs to be establish in between the individual and the Media server in order for the network to provide the TELEVISION web traffic to the smart phone. Considering that TELEVISION is a broadcast service, i.e. a point to multipoint link is needed for mobile TELEVISION solution. To implement point to multipoint link, the mobile phone network needs to set up an IP connection between the Media server as well as each mobile customer getting the broadcast at the same time. These many links will easily overwhelm the capacity of the cellphone network and also obstructs various other voice as well as information website traffic that needs to utilize the network.
For mobile TELEVISION to utilize IPTV, the IP multicast function requires to be carried out on the mobile phone network. Multicasting is the technique of transmitting a solitary video signal simultaneously to numerous end customers. All visitors receive the same signal at the same time however there are no different streams (connections) for each recipient. IP multicast is widely utilized in the distribution of program TV solutions over IP networks. It dramatically lowers the quantity of data transfer called for to transmit excellent quality IPTV web content throughout a network. This is due to the fact that just a solitary copy of every video stream requires to be sent to a router, which in turn makes a duplicate of that stream for the asking for devices. Not just does multicast reduce the bandwidth demands of the network but the processing power iptv server of the Media web server can also be kept reasonably reduced because it just transmits one copy of an IPTV stream each time.
Although the present 3G mobile network from AT&T and Verizon does not have IP multicast, however, the next 3G mobile network upgrade from both carriers may consist of the IP multicast attribute. For AT&T Wireless, the following network upgrade will certainly be HSPA (Broadband Package Gain access to) which supports the MBMS (Multimedia Broadcast Multicast Solutions) function. For Verizon Wireless, the next upgrade will certainly be EVDO Rev A which sustains the BCMCS (Program and also Multicast Solutions) attribute. For this reason, the future mobile TV service from both AT&T Wireless as well as Verizon Wireless may utilize IPTV implementation.
