Remote Configuration
Output Status and Settings Web Page
Use the Output Status and Settings web page ( Figure 27 on page 45 ) to
monitor the audio outputs and to set the AES CUV Bits Pass Through and the
AES Resolution controls.
• Processed Stream Name – displays the name for each channel.
• AES CUV Bits Pass Through – the control bits that are part of each subframe
of AES data are defined as C (Channel status), U (User), and V (Valid)
bits and the Z bit, which carries the AES block frame position block
start. For the control and status bits in the CUV positions of each audio
channel, and the Z marker for each stream (pair of channels), there is a
buffer on the module that handles the asynchronous timebase slips
between the input and output AES stream frequency.
This buffer will drop or repeat an entire block (occurring every 192 sam-
ples) of CUV bits when the two timebases cross a block boundary rather
than drop or repeat individual bits from the block.
A control is provided on the AES Outputs web page for enabling or dis-
abling the controls bits in an AES signal called the
AES C/U/V Bit Pass
Through ( Figure 27 on page 45 ). These bits may be generated locally at
the AES output of the module (Pass Through disabled) or taken from
the AES stream coming from an audio input.
• If the box is checked, refer to Table 2 on page 44 .
• If the box is not checked, the C bit is calculated.
Note When a Force Audio Mode selection is changed on the Input Status and Set-
tings Web Page on page 34 , you must manually set the AES CUV Bits Pass
Through control to Enabled or Disabled as desired.
• AES Resolution –
• If the AES CUV Pass Through box is checked, the AES Resolution is dis-
played Non-Applicable and the AES resolution is 24 bits.
• If the AES CUV Pass Through box is not checked, the resolution can be
chosen between 20 and 24 bits.
