Video record (encoder) problems
Problem Possible Causes Corrective Action
Encoder# %d failed to initialize
on slot J-N. Defective board, or problem
with internal software. Check
system status. Do one or more of the following:
• Restart the Profile XP
system.
• Replace the board.
• Contact Support.
Encoder# %d failed to initialize
on slot J-N.
The video system is unable to
establish inter-processor
communications for the encoder
on slot J-N. Media recording
tasks may fail.
The encoder on slot J-N failed to
initialize because it was
deprived of a system wide
resource (such as a DMA
channel).
Interprocessor communication
error between the encoder's
media driver on the
Real-Time-System board and
the driver on Encoder board.
Recording tasks may fail.
The storage system is
responding too slowly to the
encoder media driver. Video
may be dropped shortly. Verify
that the storage system is not
exceeding bandwidth limits.

The Profile has detected
frequent CRC errors (more than
10 times an hour) on SDI input
on slot J-N. This could result in
bad recording. Check the SDI video input(s) for
bad signal sources or bad
cabling
