vtrsyncinfo(1)
NAME
vtrsyncinfo - MSB video sync information tool
SYNOPSIS
- /usr/vtr/bin/vtrsyncinfo [ -host hostname ]
DESCRIPTION
vtrsyncinfo is a video synchronization information utility for MSB.
It can be used to determine if a system's video input and output ports
are in-sync.
vtrsyncinfo has the following options:
- -host hostname
- Check the video sync of the video ports on the host
specified by hostname.
If this option is not specified, vtrsyncinfo will check the local
host.
- -baseport
- Specify the video port against which other ports will be compared in
determining their sync phase differences. If this option is not
specified, vtrsyncinfo
will use the first video port found. A video port is specified in the same
manner as it is displayed by this tool: "MFCODEC_2.DigitalInput" or "MFCODEC_3.DigitalOutput".
For example, to specify the input port of MFCODEC_2, use
"MFCODEC_2.DigitalInput".
(NOTE: a house timecode port cannot be specified as the baseport)
- -probe
- Cause vtrsyncinfo to attempt to start all video ports in the
system
before sampling their video sync. Choosing this option will cause color
bars to be output by all output video ports not currently in use, so use
with caution. If this option is not specified, sync information for any
video ports that are not running will be missing or inaccurate.
- -tc
- Cause vtrsyncinfo to display sync phase information for any
configured
house timecode inputs in the system.
- -loop
- Cause vtrsyncinfo to re-sample and re-display sync information
once
per second.
- -help
- Display vtrsyncinfo usage information
- -verbosity level
- Specify level greater than 0 for debugging information.
DISPLAYED INFORMATION
vtrsyncinfo displays three pieces of information for each port:
- video standard
- Indicates if the port is synced to a 525-line or 625-line signal. For
house-timecode ports, this also indicates drop-frame or non-drop-frame
mode in 525 mode.
- sync source
- Indicates the video sync signal to which the port is synced. For input
ports, this is always the input signal. For output ports, it will be one
of the following:
- internal
Internal clock
- external
External genlock (GEN-IN) video ref signal
- digital-input-link-a External
genlock to digital input link A
- digital-input-link-b External
genlock to digital input link B
- phase offset
- Indicates the vertical and horizontal phase offset of this port with
respect
to the base port. Vertical phase offset is displayed in lines. Horizontal
phase offset is displayed in microseconds.
