7814UDX-4K Series
HD/3G/UHD Up/Down/Cross Converters
Revision 1.2
Page - 35
Enable Enables the sample rate converters for PCM audio.
Bypass
Bypasses the sample rate converters.
This setting should be used for non-PCM audio.
Auto
The module will automatically detect PCM and non-PCM audio and automatically turn
on/off the SRCs as required. Note that all SRCs are set to bypass as soon as a source of
non-PCM audio is detected within any of the 16 internally processed audio channels
Audio Embedder Enable: The module has four audio embedders that each inserts one group of audio
into the outgoing serial digital video. For the sake of brevity, only the control for Audio Embedder 1 is
discussed in further detail. Each embedder has an Enable and Disable function as shown below.
Disable Audio embedding for group 1 will be disabled.
Enable Audio embedding for group 1 will be enabled.
C-Bit: This control allows the user to set the C-Bit Control. Using the C-Bit Control drop down menu, the
user can select from the following options:
Preserve This option preserves/passes the C-Bit settings from audio inputs to audio outputs.
Replace This option replaces the C-Bit settings to the default values by the module.
Audio Monitor
The Audio Monitor section allows the user to view video and audio parameters that are monitored. This
section is for read-only purposes and the parameters herein cannot be modified.
SRC Status: This parameter displays the status of the Sample Rate Converters (SRC). The SRC status
will display either E nable or Bypass .
Audio Delay: The Audio Delay parameter displays the current delay/latency through the audio
processing path in milliseconds ( ms).
Video Delay: The Video Delay reports the current video processing delay/latency through the module in
milliseconds (ms).
Audio Group Presence: The Embedded Group 1 Input parameter displays the presence of audio in
Group 1.
Group 2, 3 and 4 have the same functionality.
