In this situation, stereo enhancement devices combined with aggressive audio processing could render the RDS subcarrier unreceivable.This allows for quick identification of radio program type, based on country, coverage area, and program reference number.
Le Radio Data System (RDS) est un service de transmission de données numériques en parallèle des signaux audio de la radio FM en bande II. The way to turn traffic announcements on and off on varies between radios. First block of every group, will always be the program identification code. More modern composite clippers include filtering to protect the RDS subcarrier.There are a growing number of RDS implementations in portable audio and navigation devices thanks to lower-priced, small-footprint solutions.The data-link layer describes the baseband coding of which the largest element in the structure is called a "group" sized 104 bits wide.
RDS Radio Data System Acronyms and Abbreviations; RDS Code Meaning Description; AF: Alternative Frequencies: A list of a station's frequencies in adjacent transmitter areas. The RDS system is set up to detect local radio travel news. RDS standardizes several types of information transmitted, including time, station identification and program information.

Youâll also see information about the station (the station name and other data), rather than just the frequency on the radio display in your car.Press the Seek/Track button to turn RDS on if itâs off.Press the Menu button until you see RDS (On/Off).Our certified mechanics come to you ã»Backed by 12-month, 12,000-mile guaranteeã»Fair and transparent pricingYour carâs radio is equipped to access the Radio Data System (RDS), which lets you do a number of different things. Each group type may have a secondary version availableThe station name and decoder identification code is sent progressively over 4 groups, where the offset is defined by bit C1 and C0.As we have already described previous fields above, these dot points below show just the application specific fields.As far as implementation is concerned, most car stereos will support at least AF, EON, REG, PS and TA/TP.The RDS sub-carrier at 57 kHz occupies ±2 kHz of the composite spectrum which in theory keeps it above the upper cutoff of the stereo subcarrier at 53 kHz.
