6-1-1. SDI IN SYNC MODE
Parameter
Channel
Default
Description
SDI SYNC
Group1 to 4
Auto
Selects the sync mode for embedded audio
processing. (3G/HD-SDI)
Auto
Automatically selects Sync or Async
mode according to the information in
embedded audio.
Sync
Processes audio in synchronous
mode.
Async
Processes audio in asynchronous
mode.
* The "asx" of the UDW (user data word) bits in embedded audio packets indicates the
audio sync mode.
* If
Sync
or
Async
is selected, it is also set in the "asx" of the UDW bits in output audio.
NOTE
Asynchronous audio mapping can only be performed on a per-group basis.
Otherwise, some audio channels may be noisy or output improperly due to the mixture
of synchronous and asynchronous audio channels in a group.
SDI embedded audio input cannot be assigned to output audio in Mininum Delay
mode.
6-1-2. SDI IN PCM MODE
Parameter
Channel
Default
Description
SDI PCM
Group1 to 4
Auto
Selects PCM (linear PCM, uncompressed) or
non-PCM (non-linear PCM) mode for embedded
audio processing.
Auto
Automatically selects PCM or
non-PCM mode according to the
information in embedded audio.
PCM
Processes audio in PCM mode.
NonPCM
Processes audio in non-PCM mode.
* The PCM or non-PCM information is included in the corresponding Channel Status bit.
PCM and NonPCM
Linear PCM audio
indicates raw and uncompressed digital audio data, which is encoded
from analog audio signals using the Linear Pulse Code Modulation (LPCM) method.
NonPCM (non-linear) audio
indicates digital audio data other than linear PCM audio and
includes compressed audio streams such as Dolby E or AC3.
IMPORTANT
Note that some audio channels may be output improperly if PCM and non-PCM or
non-PCM of different-format audio channels are included in a group.
