Abstract
An apparatus for controlling a data rate in a data client for a digital audio broadcasting system includes a buffer for storing data, a codec for coding data, and a control module for controlling a bit rate of the codec in response to a level of the data in the buffer. A method performed by the apparatus is also included.
Claims20
An apparatus for controlling a data rate in a digital audio broadcasting system comprising:
- a buffer for storing streaming service data clocked at a first data rate;
- a bit rate controllable, phase continuous codec for compressing the streaming service data received from the buffer to produce compressed data, wherein the codec is phase continuous at bit rate changes in codec output;
- an importer requesting streaming service data from the codec at a second data rate different from the first data rate;
- an exporter to multiplex the streaming service data with digital audio data to generate multiplexed data in an output signal;
- and
- a control module for controlling a bit rate of the codec in response to a level of the streaming service data in the buffer, wherein the control module compares the level of the streaming service data in the buffer to a first threshold level and reduces the bit rate of the codec when the level of the streaming service data in the buffer exceeds the first threshold level.

A method for controlling a data rate in a digital audio broadcasting system comprising:
- storing streaming service data clocked at a first data rate in a buffer;
- using a bit rate controllable, phase continuous codec to compress the streaming service data read from the buffer, wherein the codec is phase continuous at bit rate changes in codec output;
- and
- controlling a bit rate of the codec in response to a level of the streaming service data in the buffer;
- multiplexing the streaming service data with digital audio data to generate multiplexed data in an output signal;
- requesting streaming service data from the codec at a second data rate different from the first data rate;
- and
- outputting the compressed data, wherein the step of controlling the bit rate of the codec comprises reducing the bit rate when the level of the streaming service data in the buffer exceeds a first threshold level.
