RDS can send a clock signal with sub-second precision but with an accuracy no greater than 100 ms and with no indication of clock stratum. Not all RDS networks or stations using RDS send accurate time signals.
Introduction to FM-Stereo-RDS Modulation
· PDF 檔案The basic clock frequency is obtained by dividing the transmitted RDS sub-carrier frequency (57 kHz) by 48. Consequently, the basic data-rate of the system is 1187.5 bits/second.

RDS for FM Radio
Your RDS-equipped receiver picks it up and automatically resets itself even if you’ve never even looked at the clock before! And RDS is smart enough to figure out Daylight Savings Time, different time zones (an important feature for long distance truckers).

CT (Clock Time) : RDS 데이터를 통해서 1분 간격으로 시간 정보를 보내 준다. 따라서 라디오 시스템의 시간을 항상 정확하게 동기화 할 수 있다. 참고로 정밀도는 100ms 이다.
RDS joined over 70 exhibitors at the Automotive Management Live 2019 event held at the NEC, Birmingham on 7th November. The one day event saw visitors from over 500 organisations connect with a full range of suppliers to the automotive industry.
Annex WiFI RDS
Annex WI-FI RDS is a powerful scripts interpreter for the popular ESP8266 WI-FI module. The module can be managed with a dedicated WEB ID E and an associated AnnexToolKit utility suite . Annex WI-FI RDS provides the following main functionalities:
RDS/RBDS and RadioText Plus (RT+) FM Receiver
Clock extraction: To perform biphase symbol decoding, a clock matching the RDS/RBDS symbol rate of 1187.5 Hz is extracted from the 19 kHz pilot tone. Note, 1187.5 Hz x 16 = 19 kHz. To account for frequency offsets, frequency division is used to extract the
It´s an simple RDS decoder based on TDA7330B RDS demodulator and AT90S2313 (obsolete part, replace with Atmel ATtiny2313) controller. The RDS data is displayed on an 2×16 character LCD. It shows program service name, RDS clock, TA flag status and scrolling 64 characters long radio text.

Radio-controlled clock showing incorrect time
If the clock uses both mains power and a battery, remember to switch on the mains power and allow the clock to set before inserting the battery. If this is not done, the clock may well run an hour fast or an hour slow (If the clock’s manual indicates a different procedure to this, follow that instead)
Amazon RDS Database Monitoring
RDS monitoring helps maintain the availability and performance of Amazon RDS instances and other AWS solutions. RDS monitoring provides DBAs with data associated with different aspects of their AWS solutions, so they can better troubleshoot issues before they impact the performance of the database or web-based service.
