Output Rate Mode (DD 2.0)
The Output Rate parameter sets the current output audio bit rate for the audio channel. The
output rate value is affected by the DD 2.0 Coding Scheme and Encoding Mode parameters. This
results in different available options for each combination of Coding Scheme and Encoding
Modes. The following table details the available values of the DD 2.0 Output Rate for each
available Encoding mode.
The DD 2.0 Output Rate default value is 192 Kbps. The following table details the available values
of the DD 2.0 Output Rate for each available Encoding mode.
The Output Rate default value is 192 Kbps.
NOTE:
When setting the latency control parameter to low delay, the audio output rate must be set to a high
rate (minimum of 384 Kbps). If the rate is not high enough, the encoder displays a
Dependency Check
message.

5.4.1 Latency Control (MPEG-2/MPEG-4 AVC)
