7. 7 A. Magenta DEFINITIONS Scope Study Group 6 “Broadcasting Services” Scope of 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.
