Following a T2 Study Mission which reported to the joint
TM/CM meeting in June 2006, this group
aims to define the physical layer for the next generation of terrestrial
DVB. The intention is to specify a
system which improves on the performance of the current DVB-T standard
according to requirements specified by the CM-AMT (Advanced Modulation for Terrestrial DTV) group.
The specific goals are:
- To develop
methodologies for comparing likely candidate technologies for DVB-T2, and
perform initial studies.
- Once indicative
commercial requirements have been drafted, issue a Call for Technologies
in the areas of modulation, channel coding and signal pre-conditioning
- To take into account
the requirements of higher layers (e.g. MAC layer and application layers)
in the definition of the radio interface.
- To assess and select
candidate technologies according to the commercial requirements and
timescales to design a system suitable for terrestrial broadcasting
- To draft a candidate
specification(s) (based on final commercial requirements) to be taken to
- To steer and assist
in the verification of the specification(s) (e.g. by testing equipment
- To maintain the
specification(s) as required.
