V6418 Short Delay Mode 

 

The V6418 can be set in Short Delay Down Conversion mode in the menu: 

ENG’ING

 : 

DownConv 

: 

ShortDel

. This mode applies only when the V6418 operates as a HD to SD down converter or a SD to 

SD bypass. 
 
This is a limited feature operation mode, designed for monitoring purposes and not intended for 
broadcasting. Its main characteristic is a reduced input to output delay, compared to the standard down 
conversion or standard SD bypass modes. The image quality in the short delay down converter is slightly 
lower than in the standard down converter. In the short delay SD bypass there is no quality loss compared 
to the standard SD bypass. 
 
When the short delay mode is selected, the input to output delay is < 1 ms for down conversion and < 10 
us for SD bypass. 
 
For down conversion, only 1080i50, 1080i59, 720p50 and 720p59 input standards are supported. In the 
same way, only anamorphic and centre cutout aspect ratio conversions are implemented. In SD bypass 
the aspect ratio cannot be changed. 
 
For both short delay down conversion and short delay SD bypass modes, only Video Processor Amplifier 
(VP), Audio Handling (AH) and Closed Caption (CP) options are available. In case of input video failure, 
the output is switched to black.
