Põhitekst
The present document specifies technical characteristics and methods of measurements for transmitting equipment for broadcast sound services using the Digital Audio Broadcast (DAB) modulation system operating in VHF band III (174 MHz to 240 MHz). DAB transmissions are licensed by national administrations. The Final Acts of the CEPT T-DAB Planning Meeting Constanţa, 2007 (WI95revCO07) and the Final Acts of the Regional Radiocommunication Conference for planning of the digital terrestrial broadcasting service in parts of Regions 1 and 3, in the frequency bands 174 MHz to 230 MHz and 470 MHz to 862 MHz (RRC-06) provide spectrum masks for Out-of-Band emissions under different conditions. These requirements are represented by four transmission cases in the present document, see table 0. The license conditions set by the national administration stipulate which transmission case (Out-of-Band spectrum mask) applies. Table 0: Transmission cases Case; Description; Identification in WI95revCO07; Identification in RRC-06. 1; Applicable to DAB transmissions operating in areas critical for adjacent channel DAB to DAB interference, and in any case when it is necessary to protect other services operating on adjacent frequencies on a primary basis; 1: critical; 2: sensitive. 2; Applicable to DAB transmissions when no other case applies; 2: non-critical; 1: non-critical. 3; Applicable to DAB transmitters in exceptional circumstances to protect safety services; Critical case considering protection of distress and safety frequencies; ;. 4; Applicable to DAB transmissions operating on a case-by-case basis in certain areas; ; 3: sensitive in certain areas where channel 12D is in use. NOTE: The relationship between the present document and essential requirements of article 3.2 of Directive 2014/53/EU is given in annex A.
