Genlock
Reference lock; Input lock; free run.
Reference Lock and Input Lock modes allow output formats to be locked to same frame rate reference or input -
e.g. 1080i 50 can be locked to 50Hz SD. Locking is not possible for differing frame rates, e.g. 1080i50 to
720p59.94.
Genlock phase adju0.5F in output pixel steps. (Control allows range to cover worst-case standards). Only
available when reference locked (also see limitation above). This control is disabled when input locked, when a
fixed, minimum delay is set.
If the genlock source and video output are the same frame rate (50 or 59.94Hz) genlock will lock the output to the
vertical phase of the source, giving consistent and repeatable processing delay.
Sync mode
Disables ARC feature when input and output formats are the same. This gives the lowest latency.
Signaling reader
The unit can be configured to automatically control the conversion depending on the read value of the incoming
L23, VI, or SMPTE2016-1 (AFD) active format descriptors.
When no valid signaling is recognized, the user can select whether to hold the current conversion or default to the
current manual conversion setup. These conversions, assuming the input and output are of the same frequency,
will be clean. Additional controls are provided to allow configuration of the format and standard of each of the
signaling types:
L23
- Standard ETSI/AFD
- Line 10-23
VI
- Standard SMPTE/AFD
HD inputs only support SMPTE2016-1 (AFD), L23 is valid only on 625 inputs and VI on all SD inputs.
Output signaling
Individual control for each of L23, VI and SMPTE2016-1 (AFD) to be inserted on the output, to allow Automatic
generation, deletion, passing or always forcing to a user configured value. There are also a number of controls to
allow configuration of the format and standard of the output signaling:
L23
- Standard ETSI/AFD
- Line 10 – 23
- pass/setting of non Aspect ratio bits
VI
- standard SMPTE/AFD
- pass/delete non AFD data
SMPTE 2016 is valid on all output standards, VI is valid on SD outputs and L23 is valid only on 625 outputs.
DHCP
Enables/disables DHCP address discovery.
IP Address
Manual setting of static IP address for non-DHCP networks (Default IP address 192.168.0.100), net mask, default
gateway.
