DOLBY CONFIGURATIONS IN XT[2] SERVERS
Case 1: The 5.1 audio signal is carried on 6 discrete PCM audio channels
•
Available on an XT2 in all configurations
• The audio can be analogue, digital or embedded depending on the configuration
• In AES audio, if the audio is correctly genlocked to the video, the sample rate
converter can be switched off.
Case 2: The 5.1 audio signal is coded in the two-channels Dolby E
standard
•
Dolby E over AES/EBU links
o Set the configuration of the pair of channels carrying the Dolby E signal to
“DY” in the AVCFG. This has two effects :
• It disables the sample rate converter on the input channels
• It forces all transitions to a hard cut.
If the sample rate converter is activated and the audio configuration is a mix
between PCM audio over AES and Dolby E over AES, the sample rate converter
will only be applied to the PCM over AES signal.
• Dolby E Embedded in the SDI/HD SDI stream
o Set the configuration of the pair of channels carrying the Dolby E signal to
“EY” in the AVCFG. This will force the transition to a hard cut.
o The sample rate converter parameter does not apply to embedded audio.
The Dolby E transitions will be correct as long as :
• the configuration is correct
• the AES stream containing Dolby E is correctly synchronised with the video
Dolby E transitions will not
be correct (2 frames of mute at the transitions) if the
AVCFG is set to E instead of EY or D instead of DY.
Audio effects (scrub, slow motion) are not possible in Dolby E. If they are used
anyway, the audio will be muted.
1.3.6 3 D & 1080P DUAL-STREAM MANAGEMENT
PRINCIPLE
The 3D and 1080p features is based on the use of two physical channels
(recorders or players) seen by the server as a logical channel. Consequently, two
physical recorders or players are required but only one is assigned in the
Channels Configuration. These two configurations require the record and playout
on synchronous channels.
