Technical ModuleWorkspace >
The Technical Module provides technical expertise and is open to the technical experts of all Members. It also provides a forum for the co-ordination of R&D activities.
The Technical Module works according to Commercial Requirements set down by the Commercial Module. It delivers specifications for one or more Standards via the Steering Board to the recognized standards setting entities, notably the EBU/ETSI/CENELEC Joint Technical Committee.
It provides a conduit to other relevant standardization activities, including MPEG, for the purpose of meeting the objectives of the DVB Project.
While DVB is a commercially driven organization, it is clear that the TM is the “engine room” of the project. DVB members associate a very high priority to the TM and its work.
