Mobile TV may be watched on a smart or 3G mobile telephone, such as the LG Vu or Samsung SCH u620 clever phone. Both AT&T Wireless and Verizon Wireless provide cell TV offerings. For Verizon, it is VCAST TV and for AT&T, it’s far AT&T Mobile TV. Both AT&T and Verizon Mobile TV use MediaFLO technologies from Qualcomm to broadcast the VHF (719 MHz Center frequency) virtual TV alerts to the cellular telephones. Mobile TV provider from extraordinary carrier package unique set of TV channels in its broadcast (within the range of 10 to 12 TV channels in a primary package).
Mobile TV provider does not use the mobile iptv service provider phone network to transmit the TV alerts. Instead, it uses a separate network to distribute, transmit and broadcast the TV signals to the cell phones. It only makes use of the mobile smartphone network to offer interactivity and user authorization with the TV provider provider. Since the 3G cell cellphone community from AT&T and Verizon are both succesful to hold IP traffic, it appears to be obvious that the most effective implementation for mobile TV is using IPTV. A appropriate instance is AT&T already the use of IPTV in its U-verse carrier (internet, smartphone and TV).
To understand why cellular TV does no longer use IPTV, the unicast nature of the mobile telephone community desires to be explained. The current 3G (UMTS, EVDO) mobile smartphone community are designed to carry unicast visitors only, i.E. Point to point connection desires to be establish between the consumer and the Media server in order for the community to supply the TV visitors to the cellular smartphone. Since TV is a broadcast carrier, i.E. A factor to multipoint connection is needed for mobile TV provider. To put in force point to multipoint connection, the cell smartphone network needs to installation an IP connection between the Media server and every mobile person receiving the printed simultaneously. These many connections will without difficulty overrun the capability of the mobile cellphone community and blocks different voice and information traffic that wishes to use the community.
For cell TV to use IPTV, the IP multicast characteristic desires to be implemented at the mobile cellphone community. Multicasting is the approach of transmitting a single video signal concurrently to more than one give up users. All viewers get hold of the identical signal on the identical time but there aren’t any separate streams (connections) for each recipient. IP multicast is broadly used within the transport of broadcast TV offerings over IP networks. It notably reduces the amount of bandwidth required to transmit excessive great IPTV content material across a network. This is due to the fact handiest a single replica of every video circulation desires to be despatched to a router, which in turn makes a duplicate of that flow for the asking for devices. Not only does multicast lessen the bandwidth requirements of the network but the processing strength of the Media server also can be saved fantastically low as it only transmits one replica of an IPTV circulate at a time.
