Abstract
A method and device for transmitting audio data and text data to an RDS capable radio receiver by a wireless device is disclosed. The device includes a receiver for scanning a frequency range to detect an available radio frequency based on predetermined criteria. The device also includes a transmitter for transmitting data on a detected frequency that comprises RDS message data. Other systems and methods are also disclosed.
Claims20
A method for a transmission of data from a mobile device to a RDS capable radio receiver, comprising:
- scanning a frequency range to detect a frequency channel that meets a predetermined criteria of availability;
- and
- transmitting data on the detected frequency channel that comprises RDS message data comprising at least one of:
- a Travel Announcement, Traffic Program, or Enhanced Other Network.
A device for radio transmission of data for being received by a RDS capable radio receiver, comprising:
- a receiver for scanning a frequency range to detect an available frequency based on a predetermined criteria of availability;
- and
- a transmitter for transmitting data on the detected frequency that comprises RDS message data comprising at least one of:
- a Travel Announcement (TA), Traffic Program, or Enhanced Other Network.
A communication device, comprising:
- a receiver for scanning a frequency range to detect available radio frequencies on which no broadcast transmissions or interfering signals are currently received as determined by a predetermined criteria for availability;
- and
- a transmitter for transmitting audio data on the detected available frequency channel to an RDS radio receiver as a Travel Announcement, or Traffic Program, and/or Enhanced Other Network;
- wherein the transmitter transmits data on the detected frequency and causes the RDS radio receiver to automatically switch to the detected frequency and therein transmit the data received from the communication device on the detected frequency.
