TODAY’S PATENT – METHOD AND DEVICE FOR LOW-POWER FM TRANSMISSION OF AUDIO DATA TO RDS CAPABLE FM RADIO RECEIVER

Today’s patent was invented by Ken Mason on December 25, 2013, bearing patent no. EP1867077B1.

Recently, portable electronic gadgets that can play music have gained a lot of popularity. These music players are typically used in conjunction with headphones or earphones. The technique and apparatus for sending audio data from an audio playback device to an FM radio receiver with RDS capability are the subject of the current invention. It specifically has to do with sending audio data from a mobile playback device to an RDS-capable car radio system. Utilizing RDS to control the transmitter so that only open channels are used is the primary feature of the current innovation. The process includes scanning an FM frequency range to find available radio frequencies where there aren’t any broadcast transmissions or competing signals right now. These are channels that are free from legitimate broadcast transmission and, ideally, free from other signals that could obstruct or tamper with the audio transmission.
