ITU-R REPORT BT.2140-2 PDF

Purpose of Report

Throughout the World, countries are in various stages of switching over from analog to digital terrestrial broadcasting. The digital systems utilized in different parts of the world are described in Recommendations ITU-R BS.1114-5 (for sound) and ITU-R BT.1306-3 (for television).

This Report attempts to provide an overview of the digital switch-over situation world-wide and will be updated regularly.

In 2006, the ITU's Regional Radiocommunication Conference (RRC-06) comprising 120 Administrations in Region 1 (except Mongolia) and Iran from Region 3, adopted a treaty Agreement (GE06 Agreement) that includes a frequency Plan for the digital sound and television broadcasting service. The Plan was developed based upon the digital sound T-DAB system and the digital television DVB-T system. This is a long-term Plan which is based on a mask concept and defined protection and interference criteria that would allow for further evolution of this Plan¹.

¹ Art. 5.1.3 of GE06 Agreement:

"5.1.3 A digital entry in the Plan may also be notified with characteristics different from those appearing in the Plan, for transmissions in the broadcasting service or in other primary terrestrial services operating in conformity with the Radio Regulations, provided that the peak power density in any 4 kHz of the above-mentioned notified assignments shall not exceed the spectral power density in the same 4 kHz of the digital entry in the Plan. Such use shall not claim more protection than that afforded to the above-mentioned digital entry."
