Abstract
An audio input interface (122) receives a digital audio signal and identifies an audio bitstream which is optionally decrypted by a decryption unit (123), and decoded by an audio decoding unit (124). An audio digital to analog converter (126) converts the decoded audio bitstream to an analog audio signal which is optionally decrypted by an audio analog decryption unit (127). An analog transmitter (150) transmits the analog audio signal to a radio (110).
Claims20
A system for broadcasting audio content of a digital audio signal to a radio, comprising:
- an audio input interface receiving the digital audio signal and identifying an audio bitstream, wherein the audio bitstream comprises audio data based on a plurality of encoding methods;
- an audio decoding unit connected to the audio input interface and decoding the audio bitstream;
- an audio digital to analog converter connected to the audio decoding unit and converting the audio bitstream to an analog audio signal;
- and
- an analog transmitter connected to the audio digital to analog converter and transmitting the analog audio signal to the radio.
A method for broadcasting audio content of a digital audio signal to a radio, comprising the steps of:
- receiving the digital audio signal and identifying an audio bitstream, wherein the audio bitstream comprises audio data based on a plurality of encoding methods;
- decoding the audio bitstream;
- converting the audio bitstream to an analog audio signal;
- and
- transmitting the analog audio signal to the radio.
