EN 62106:2009

Specification of the Radio Data System (RDS) for VHF/FM sound broadcasting in the frequency range from 87,5 MHz to 108,0 MHz

IEC 62106:2009(E) describes the Radio Data System, RDS, intended for application to VHF/FM sound broadcasts in the range 87,5 MHz to 108,0 MHz which may carry either stereophonic (pilot-tone system) or monophonic programmes. The main objectives of RDS are to enable improved functionality for FM receivers and to make them more user-friendly by using features such as Programme Identification, Programme Service name display and where applicable, automatic tuning for portable and car radios, in particular. The relevant basic tuning and switching information therefore has to be implemented by the type 0 group (see 6.1.5.1), and it is not optional unlike many of the other possible features in RDS. This edition constitutes a technical revision. The main changes with respect to the previous edition are: - the list of RDS country codes, inclusive of the extended country codes, has been updated in Annexes D and N; - Annex E, containing the character code tables to be used in RDS has been updated; - RadioText Plus has been added as a new feature in Annex P; - Enhanced RadioText has been added as a new feature in Annex Q.

Spécification du système de radiodiffusion de données (RDS) pour la radio à modulation de fréquence dans la bande 87,5 MHz à 108,0 MHz

Specifikacija radijskega podatkovnega sistema (RDS) za zvokovno radiodifuzijo VHF/FM v frekvenčnem območju od 87,5 MHz do 108,0 MHz (IEC 62106:2009)

Ta mednarodni standard opisuje radijski podatkovni sistem RDS, namenjen  uporabi za zvokovno radiodifuzijo VHF/FM v območju od 87,5 do 108,0 MHz, ki lahko nosi bodisi stereofonične (sistem za pilotski ton) ali monofonične programe (glej klavzulo 2 – Normativne reference ITU-R priporočil BS450-3 in BS 643-2). Glavna cilja sistema RDS sta omogočiti izboljšanje funkcionalnosti za FM sprejemnike in jih z značilnostmi, kot so prepoznavanje programov, prikazovanje imen programov in samodejno uravnavanje zlasti za prenosne in avtomobilske radie, kjer se uporablja, narediti bolj prijazne uporabniku. Ustrezne osnovne informacije glede uravnavanja in preklapljanje morajo potemtakem biti dopolnjene s skupino tipa 0 (glej točko 6.1.5.1), kar je obvezno, za razliko od mnogih drugih možnih značilnosti v sistemu RDS.
