1、Res. ITU-R 4-5 1 RESOLUTION ITU-R 4-5 Structure of Radiocommunication Study Groups (1993-1995-1997-2000-2003-2007) The ITU Radiocommunication Assembly, considering a) No. 133 and Article 11 of the ITU Convention; b) that the work of the Radiocommunication Study Groups is involved with developing the
2、 technical, operational and procedural bases for efficient use of the radio spectrum and the geostationary-satellite orbit; c) that cooperation between the Radiocommunication Sector and international and regional organizations with regard to the development of standards for radiocommunication system
3、s and operations would provide considerable benefits, resolves 1 that six Radiocommunication Study Groups shall be set up as shown in Annex 1; 2 that, in liaison with the Telecommunication Standardization Sector, the Telecommunication Development Sector, the ITU General Secretariat and with other in
4、terested organizations, the Radiocommunication Bureau organizes the work of a Coordination Committee for Vocabulary, the scope of which is given in Annex 2. Res.

14、r K.-J. WEE (Korea (Rep. of) STUDY GROUP 6 (BROADCASTING SERVICE)1 Scope: Radiocommunication broadcasting, including vision, sound, multimedia and data services principally intended for delivery to the general public. Broadcasting makes use of point-to-everywhere information delivery to widely avail
15、able consumer receivers. When return channel capacity is required (e.g. for access control, interactivity, etc.), broadcasting typically uses an asymmetrical distribution infrastructure that allows high capacity information delivery to the public with lower capacity return link to the service provid
16、er. This includes production and distribution of programmes (vision, sound, multimedia, data, etc.) as well as contribution circuits among studios, information gathering circuits (ENG, SNG, etc.), primary distribution to delivery nodes, and secondary distribution to consumers. The Study Group, recog
17、nizing that radiocommunication broadcasting extends from the production of programmes to their delivery to the general public, as detailed above, studies those aspects related to production and radiocommunication, including the international exchange of programmes as well as the overall quality of s
