Notes: Although there are more sources from the physical inputs, the maximum
number of input streams supported is 8 for CE-x, CE-xA and CE-a, and 4 for
CE-a J2K, which can be from either of the input sources.
There must be a valid video source when using the Digital (AES/EBU) audio
input, the VCM is not designed for audio only encoding.
Any audio input can be associated with the video being processed, and the audio
encoding delay will be matched to the video encoding delay so that audio/video
synchronization (lipsync) is maintained.
All audio components are configurable on a per channel basis. Parameters include
the source of the audio, its encoding configuration and output PID.
6.9.1 Audio Input Interfaces
The Pre-processor function on the different VCMs accepts digital audio input from
either de-embedding from the HD/SD-SDI input or as a balanced (110
Ω) or
unbalanced AES/EBU input (75
Ω) from the D type back panel connector.
Additionally, on a CE-xA, analogue audio can be input through a 20 k
Ω balanced or
unbalanced input.
