8.3 Statesman error reporting
The Statesman Toolkit, which is accessible from the Audio Delay tab, has been provided
to provide comprehensive error reporting and status information.
TANDEM-300 Toolkit
Toolkit provides details of the general status of the de-embedder, embedder, and HANC
space data which includes the following:
•
'low / high sample rates' indicate incorrect number of incoming audio samples
beyond manageable error rates [both high+low = wildly varying sample rate]
•
'hanc error' indicates insufficient spare space in HANC to insert further
embedded audio, or HANC space is filled with unspecified signals, such as
'blank' space that is not true black [e.g. analogue blanking prior to A-to-D
conversion without true digital blanking applied]
•
'format' error refers to errors in the format or structure of the embedded audio
data packets
•
'invalid' digital audio signals fed to the ‘C’ embedder is indicated by the "V"
bits set to logic 'high'
•
"V" bit high is set by the AES standard as indicating 'invalid' audio data, or
possibly non-linear audio data, such as compressed multichannel audio data
which can not be directly converted back to audible signals
•
Mux ‘C’ errors indicate non operational status for that embedder, such as lack
of HANC space [HANC blanking may cure that], or some other error settings
or application error
Note:
Card–edge warnings do not appear within Statesman.
