The DVB Project has published details of a new profile for its terrestrial broadcasting standard, designed to support low capacity applications such as mobile broadcasting.
Version 1.3.1 of the Blue Book for DVB-T2 adds the new T2-Lite profile. At the same time the previous single profile has been renamed as the T2-base profile.
According to the DVB, 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.
A study initiated in 2007 to develop a second generation version of the DVB-H mobile standard was later dropped.
