MobiTV Hits 4 Million, Upgrades Tech

MobiTV has hit the 4-million subscriber mark, adding a million subscribers in the last six months as well as the six months before that, reports RCRNews. It has also announced a combination unicast/multicast system, so that if 50 subscribers are watching the same channel in one sector it will switch from unicast to multicast — saving on backhaul. CTO Kay Johansson also said that the time required to change channels is now less than a second, putting it on par with other TV services. The time required to change channels is important — when mobile TV first came out the lag in changing channels was an inhibitor to uptake. (release)
