Click on the Audio 2 tab to view and make changes to the packet processing and
audio level settings.
Packet Processing Control
HANC Data -
When
Pass
is selected, all incoming HANC packets are passed unless
the embedder settings require all or part of them to be over-written.
When
Remove
is selected, all incoming HANC packets are dropped before
embedding any new audio packets. The embedder settings determine all
embedded audio output. Disembedding is not affected.
NOTE: 2048x1080p/psf 29.97 and 30 formats support a maximum of 8 channels of
embedded audio. When one of these formats is present and embedding is turned
on, the PASS HANC setting will be ignored and all incoming packets will be
dropped before embedding any new audio packets.
3G-
SDI Level B - For 3G Level B signals, this control selects either the 16 audio
channels of input Stream A or the 16 audio channels of input Stream B for
disembedding. This setting also controls whether output Stream A or output
Stream B will receive embedded audio. This control has no effect if a 3G Level
B signal is not detected.
Sample Rate Converter
This setting determines whether AES audio inputs are passed through the sample
rate converter before embedding. Turn this setting Off for compatibility with
non-PCM bitstreams such as Dolby-E or Dolby-B.
Choose
Auto
,
On
, or
Off
for each of the indicated input channel pairs: (Ch 1/2, Ch
3/4, Ch 5/6, Ch 7/8).
• Auto - Automatically selects whether incoming AES audio is sample rate
converted. If channel status bits are detected that indicate the audio is PCM
