Geneva hosted last 24-31 October a meeting of working party (WP) 6A (terrestrial broadcasting) of Study Group 6 of the ITU Radiocommunication Sector (ITU-R).
Some 33 documents were approved at the meeting, with most concerning digital terrestrial broadcasting and the interference of other services in broadcasting service. The following stand out among the approved documents:
- Modification of Recommendation ITU-R BT. 1368-7 - Planning criteria for digital terrestrial television service in the VHF and UHF bands;
- Modification of ITU-R BT.1306-4 - correction of mistakes, data structure, methods of modulation and emission for digital terrestrial television;
- Revision of the new recommendation on the necessary requirements for using wireless microphones and the spectrum to be used;
- Revision of the new recommendation on protection requirements for broadcasting systems emitting in the long wave (LF), middle wave (MF), short wave (HF) and metric wave (VHF) bands in frequencies below 80 MHz, against radiation from power line telecommunications (PLT);
New reports on:
- Diversity in the reception of digital terrestrial television signals;
- Methods to predict coverage and planning software for digital terrestrial television;
- Characteristics of the radiation diagrams of antennas for receiving television in the ultra high frequency (UHF) band;
- Protection requirements for digital terrestrial television services against interference from mobile networks and systems;
- The switch from analogue to digital in terrestrial broadcasting;
- Calculation of coverage limits for digital terrestrial television;
- Guidelines and techniques for evaluating digital terrestrial television systems, including their coverage areas;
- Protection of broadcasting systems operating in bands below 80 MHz against radiation from PLT systems;
- Parameters for planning and coverage of the Digital Radio Mondiale (DRM) system in bands below 30 MHz.
