What is RBDS on my radio?
What is RBDS on my radio?
The Radio Broadcast Data System (RBDS) is the American equivalent of the Radio Data System (RDS) protocol, which is the standard protocol for the distribution and propagation of data by FM radio signals. The two standards (RDS and RBDS) are more or less the same.
Does FM use radio waves?
The longest waves on the electromagnetic spectrum–radio waves–carry information from a station to a receiver. But radio waves don’t carry information all by themselves. There are two ways radio stations modulate their carrier waves: amplitude modulation, or AM, and frequency modulation, FM.
What is meant by FM radio with RDS?
The Radio Data System (RDS) enables FM radio stations to send additional information along with the regular program signal. NOTE: Not all FM radio stations provide RDS service, nor do they provide the same type of service.
Where does the FM broadcast band located in the spectrum band?
Broadcast bands Throughout the world, the FM broadcast band falls within the VHF part of the radio spectrum. Usually 87.5 to 108.0 MHz is used, or some portion thereof, with few exceptions: In the former Soviet republics, and some former Eastern Bloc countries, the older 65.8–74 MHz band is also used.
What does Pty mean on a radio?
program type
PTY is for program type. Some stations put a digital encoding on the program type and you can scan for pre-defined program types like rock, news, jazz, etc.
How do you set an FM preset?
Press the TUNE + button to select the desired station. Press and hold down the ENTER button. While holding down the ENTER button, press the MEMORY PRESET + button to select the desired preset number. Hold down the MEMORY PRESET + button until the radio beeps and PRESET stops flashing in the display.
Is RDS the same as DAB?
RDS is the radio data system, a technology invented in the late 1980s which allows some data to be broadcast alongside an FM radio station. It’s not the same as DAB digital radio, which is an entirely different type of transmission. Digital radio offers crackle-free reception and a much wider range of services.
What does PTY on radio mean?
Radio programme types
Updated 7/23/2018. One or more radio programme types, such as pop and classical music can be selected for DAB*-radio. After selecting a programme type navigation only occurs among the channels transmitting that type.
What’s the difference between RDS and radio broadcast data system?
Radio Broadcast Data System ( RBDS) is the official name used for the U.S. version of RDS. The two standards are only slightly different. Both carry data at 1,187.5 bits per second on a 57 kHz subcarrier, so there are exactly 48 cycles of subcarrier during every data bit.
What can a RBD be used for on a radio?
RBDS can be used to transmit various types of data, such as data related to the transmitted radio program, including the name of the station or the name of the track or the artist. It can be used for many other purposes, particularly for hidden messages and signals.
When was the Radio Broadcast Data System published?
In 1992 the U.S. National Radio Systems Committee issued the North American version of the RDS standard, called the Radio Broadcast Data System. The CENELEC standard was updated in 1992 with the addition of Traffic Message Channel and in 1998 with Open Data Applications and, in 2000, RDS was published worldwide as IEC standard 62106.
Is the 57 kHz subcarrier compatible with RDS?
RDS compatibility. 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. However the 53 kHz cutoff is entirely dependent on the performance of the 15 kHz low pass filters used before the stereo encoder.
