The DVB Project has introduced a new profile for its popular DVB-T2 terrestrial standard for lighter applications such as mobile TV: T2-Lite.

Version 1.3.1 of the DVB-T2 specification document introduced a T2-Lite profile. This profile is intended to allow simpler receiver implementations for very low capacity applications such as mobile broadcasting, although it may also be received by conventional stationary receivers. T2-Lite is based on a limited sub-set of the modes of the T2-base profile, and by avoiding modes which require the most complexity and memory, allows much more efficient receiver designs to be used.

One possible use for T2-Lite enables the simulcasting of two different versions of the same service, with different bit-rates and levels of protection, which would allow better reception in fringe areas.

You can also see DVB-T2-Lite in action at the DVB stand 1.D81 at IBC from 9-13 September in Amsterdam.
