Mobile TV Format is a colloquial and collective name for technology standards set out for broadcasting TV services to mobile devices, mostly mobile handsets for now. Currently, there are four prevalent formats known as DMB, DVB-H, OneSeg and MediaFLO. As of December 2007, ITU approved T-DMB, DVB-H, OneSeg and MediaFLO as the global standard for real-time mobile video and audio broadcasting. Thus far, none of the four formats has secured a dominant position in the global market, except in their respective home markets.
