RDS Time Display Device
Technical Field
The invention relates to a time display device, and in particular to a RDS time display device.
Background
A RDS (Radio Data System, RDS for short) is used for sending out station name, program type, program content, traffic announcements, advertising 10 information, standard time, weather information and other information in a digital form by the use of sub-carrier in the FM radio transmission signal.
These digital signals can be recognized by a tuner with a RDS function and converted into characters to display on a display screen. The frequency modulation of the RDS receiver is in the range of 75.0-108.0MHz. The receiver 15 receives the program, and at the same time, the received station and its transmission frequency can be known through the RDS, and the other frequencies of the station will be given, and thus ensuring the received signal is in the strongest frequency via a frequency switching button.
The radio essence of the RDS is its AF function and TA function, wherein AF is 20 Alternative Frequencies. The AF function will alternatively search for the other transmission frequency of the current station. A RDS radio system is further provided with a TA function of playing traffic information. In case of emergency, the station will send a special signal to force the radio to play. In addition, a time reference transmission function, a self-aligning radio time
2015200295 30 Jan 2019 function and other functions are provided. Currently, the RDS is more widely used on cars, mobile phones and other mobile device, but not applied in the time display device, such as clocks. Moreover, it is not that the digital time sent from all stations are all accurate. As some errors incur in the time display of different clocks and it is not very accurate to tell time, so it is necessary to design a RDS time display device, which can choose between the stations with reliable time, providing people with more accurate time.
Nothing above should be read as necessarily falling within the common general knowledge.
