Mobile TV can be seen on a clever. Both Attend Wireless and also Verizon Wireless use mobile TV solutions. For Verizon, it is VCAST TV and for Attend, it is Attend Mobile TV. Both Attend and also Verizon Mobile TV use Medial technologies from Qualcomm to relay the VHF 719 MHz Center regularity digital TV signals to the mobile phones. Mobile TV solution from various carrier bundle different collection of TV networks in its broadcast in the series of 10 to 12 TV networks in a fundamental bundle.
Mobile TV solution does not make use of the mobile phone network to transmit the TV signals. Rather, it utilizes a separate network to disperse, transmit and broadcast the TV signals to the cell phones. It just makes use of the smart phone network to supply interactivity and individual authorization with the TV service provider. Because the 3G smart phone network from and also Verizon are both qualified to lug IP traffic, it appears to be apparent that the most basic application for mobile TV is utilizing IPTV. A good example is already using IPTV in its Uverse solution net, phone and TV.
To recognize why mobile TV does not utilize IPTV, the uncast nature of the cell phone network requires to be explained. The current 3G UMTS, EVDO smart phone network are made to carry uncast website traffic just, i.e. point to factor connection needs to be develop in between the individual and the Media server in order for the network to provide the TV website traffic to the cell phone. Considering that TV is a broadcast service, i.e. a point to multipoint link is required for mobile IPTV solution. To implement point to multipoint link, the mobile phone network requires setting up an IP connection in between the Media web server and each mobile individual receiving the program all at once. These numerous connections will easily overwhelm the ability of the mobile phone network and obstructs other voice and data web traffic that needs to utilize the network.
For mobile TV to make use of IPTV, the IP multicast feature needs to be applied on the smart phone network. Multicasting is the method of transferring a single video clip signal concurrently to several end individuals. All visitors get the same signal at the very same time however there are no separate streams links for each recipient. IP multicast is commonly used in the delivery of program TELEVISION services over IP networks. It significantly minimizes the quantity of bandwidth called for to send top quality IPTV content across a network. This is because just a solitary duplicate of every video clip stream requires to be sent to a router, which subsequently makes a copy of that stream for the asking for tools. Not only does multicast minimize the transmission capacity demands of the network but the processing power of the Media server can likewise be maintained fairly low because it just sends one duplicate of an IPTV stream at once.
