Error Checking
Errors are checked and concealed to ensure high quality audio. MPEG error checking uses frame-size calcu-
lations for each frame. Audio bitstream error concealment is performed, either by sample repeats or muting,
due to loss of Audio Frame synchronization or detection of CRC errors.
Dolby Digital (IBM STB13010 only)
The IBM STB13010 device is fully compatible with Dolby Digital. This device can decode Dolby Digital input,
and can output three audio data out signals to support the six channels in Dolby Digital. An S/PDIF output is
also available for either two channels of decoded data or output of the Dolby Digital stream.
Additionally, Dolby Digital Karaoke mode and Dolby Digital Surround mode (DSMOD) are supported.
DSMOD pins interface to external surround mode circuitry.
Support is also provided for several downmix combinations, dialog normalization, and dynamic range control.
