• Paraphrasing the start of the Gospel of ST JOHN, I would say:

<< In the beginning was the… “COMMUNICATION”,“COMMUNICATION”, and the communication was based on the “SERVICES“SERVICES”>>.

– The first Service was the “LANGUAGE”– The second `` `` `` “HIEROGLYPHIC”– The third `` `` `` “WRITING”

All of these Services are “INTERACTIVE”“INTERACTIVE” in due time.

• Historically, the use of Electromagnetic - Waves for Telecommunication, has originated the following Services :

– Telegraph / Data– Telephone– Broadcasting (Sound and Television)

• The new technical developments (e.g. digitalisation) and the new techniques lead to the “Convergence”, and I can say that:

““INTERACTIVITY is daughter of CONVERGENCE”INTERACTIVITY is daughter of CONVERGENCE”

Scope Scope of Study Group 6 “Broadcasting Services”Study Group 6 “Broadcasting Services” - (agreed by RA 2000)-

• Radiocommunication broadcasting (terrestrial and satellite), including vision, sound, multimedia and data services principally intended for delivery to general public.

Broadcasting make use of point-to-everywhere information delivery widely available consumer receivers. When return channel capacity is required ( e.g. for access control, interactivity, etc.) broadcasting typically use an asymmetrical distribution infrastructure that allows high capacity return delivery link to the service provider. The production and distribution of programs (vision, sound, multimedia, data etc.) may employ contribution circuits among studios, information gathering circuits (ENG, SNG, etc.), primary distribution to delivery nodes,and secondary distribution to consumers.

The Study Group, recognizing that radiocommunication broadcasting extends from the production of programs to their delivery to general public, as detailed above, studies those aspects related to production and radiocommunication, including the international exchange of programs as well as the overall quality of service.
