Statesman error reporting
The Statesman Toolkit, which is accessible from the Toolkit tab, provides comprehensive
error reporting and status information.
TANDEM-110 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" & "D" embedders are 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" or Mux "D" 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
