![]() With this exception, RDS and RBDS have quite different Program Types.Īs an example, transmissions with RDS PTY5 are categorized as “Education” broadcasts, while RBDS PTY5 refers to “Rock” transmissions. This is available both for the European RDS and the American RBSD. PTY31 is intended for emergency announcements, in case of imminent dangers, natural disasters, and so on. By doing this, your receiver will tune itself only to those stations of your preferred type. The most useful part of this code is that you can set the radio to a certain PTY. Thus, each transmission falls into one of the 31 existing types. RDS has the ability to identify the type of each radio transmission. Without the driver having to get his hands off the wheel, RDS does all the work, re-tuning the radio to whatever the driver was initially listening to. This feature is most useful on long trips, when the car (and implicitly, the radio) goes out of range of a radio station. Whenever the signal of a station becomes too weak, AF will re-tune your radio automatically to a stronger signal, as long as that signal belongs to the same transmission. If the radio is connected to the car, CT can also synchronize the time and date displayed on the car’s board computer. Thanks to this, the date and time of your radio can be synchronized with the date and time transmitted by the Radio Data System. There are stations that prefer to transmit a static message, such as a motto, etc. Most of the time, Radio Text is used to display the name of the song you are listening to, as well as its artist. Unlike PS, Radio Text is a feature that allows the radio station to transmit messages of up to 64 letters and numbers. This one is very similar to the first one, PS. Moreover, most radios are able to associate PS (The Program Service Name) of a station along with its frequency and Program Identification code (PI). Program Identification is one of the most fundamental features of RDS, and also one of the simplest.īy this, the name of the radio station is displayed by no more than 8 letters. Thus, it can connect to either of the two depending on which has a stronger signal. ![]() ![]() When two transmissions use the same code, the radio considers them to be the same unique transmission. Programme Identification is the most important code for the Radio Data System, as most of the other functions are based on it.Įvery radio station has a completely unique 4-character code, called a PI. In what follows we are going to cover as many facilities offered by RDS. In this way, the driver no longer has to do this task manually.īesides, these are just two of the many possibilities of using the Radio Data System. In addition to this, when the radio goes out of range of a transmitter, the radio will automatically re-tune to the nearest transmitter of a similar kind. The role of the Radio Data System – or RDS – is to provide the radio listener with useful information, such as traffic reports, program information, and so on. One example would be the auto-tuning feature.RDS provides the listener with more information.The benefits it brings are useful especially for drivers who travel long distances by car.Īlthough this system was first developed and used in Europe, RDS has become popular all around the world due to its advantages. Nowadays, Radio Data System is used by almost all radios, especially by car radios. version of this has a slightly different name (RBDS or Radio Broadcast Data System) but the facilities are almost the same. RBDS stands for Radio Broadcast Data System.After reading this article, you will know what RDS radio is, how it came to be and how it helps us every day.Īs you will see, this communications protocol has allowed radios to be much more than just simple devices that receive certain electromagnetic waves. On the contrary, we could argue that radios have remained relevant to this day precisely because of the constant upgrades over time. Since they were first conceived and until now, radio technology hasn’t stood still at all.
