Radio Data System RDS is a communications protocol standard for embedding small amounts of digital information in conventional FM radio broadcasts. RDS standardizes several types of information transmitted, including time , station identification and program information. Both versions carry data at 1, The data is sent with an error correction code , but receivers may choose to use it only for error detection without correction. RDS defines many features including how private in-house or other undefined features can be "packaged" in unused program groups. The EBU Technical Committee launched a project at its Paris meeting to develop a technology with similar purposes to ARI, but which was more flexible and which would enable automated retuning of a receiver where a broadcast network transmitted the same radio programme on a number of different frequencies.

The HD seek function helps to identify stations broadcasting in High Def and those so-called "hidden channels" be easily tuned in and enjoyed. Fill the presets with Auto Seek, which finds the active stations automatically. This stylish radio features 3 alarm timers with HWS that wakes you to your choice of buzzer or radio, starting with a soft low volume. Radio stations may not satisfy your craving for tunes, which is where AUX-In comes in for other devices to play through the HDR's premium speaker. A built-in stereo headphone output is offered for private listening. We Use Cookies. Read More Accept. Overview Features Specs Bundle Support. Color White Go to White page White. Buy Now.

The RBDSPhyDecoder helper receives the captured signal from a file or the live signal from the radio and performs these steps:. Pilot tones at 38 kHz and 57 kHz can be generated by doubling and tripling the frequency of the 19 kHz pilot tone [ 2 ]. Frequency tripling : Raise the complex representation of the 19 kHz pilot tone to the 3rd power to triple its frequency and obtain a 57 kHz pilot tone. Typically, the frequency-tripled 19 kHz pilot tone suffices for coherent demodulation. The PHY receiver contains a Costas loop to compensate for such time-varying phase offsets.

This standard was improved over the years and later adopted within the United States in , with slight modifications, by the National Radio Systems Committee. Because the concepts I am discussing often are interchangeable between the European and American standards, I will refer to these standards collectively as RDS. Earlier in this decade, major U.

History of radio International broadcasting. Read Edit View history. While the country code is specified by the standard, bit 11 to bit 0 is specified by each country local authorities. A distinct bit offset word is modulo-2 added to the parity bits of each block. Content Subscription-Free Access digital entertainment and technology, and discover fresh digital content including more stations, better sound and no subscription fees. Enabling scopes requires extra computational effort and may preclude real-time decoding. The station name and decoder identification code is sent progressively over 4 groups, where the offset is defined by bit C1 and C0. In other projects. Modified Julian Day Number.

The RDS subcarrier typically uses 2—4 kHz of carrier deviation. Buy Now.

As we have already described previous fields above, these dot points below show just the application specific fields. Real Time Clock with Functions This stylish radio features 3 alarm timers with HWS that wakes you to your choice of buzzer or radio, starting with a soft low volume. In this situation, stereo enhancement devices combined with aggressive audio processing could render the RDS subcarrier unreceivable. Electronics Notes. This allows the RDS decoder to tolerate phase inversion of its input. We Use Cookies. Note, Current affairs. The new clock-wide amplitude level corresponds to the symbol's bit representation. The receiver synchronizes to groups and blocks by checking CRCs on each 26 bits until synchronization is achieved. PDF Technical report. There is no gap between blocks.
