OmniTek 2.3 User Manual

 

 

The Options menu in the Mini-Pic window includes the following options: 

Pulse/cross 

The Pulse/cross mode delays the video by half a frame both horizontally and 
vertically, to emulate the HV delay mode of CRTs. This can give a clearer view of 
data adjacent to blanking  

 This mode can be more useful if the ‘TRS Pass’ mode is also enabled in the 

Analyzer menu of the main application. 

Colour options 

The Mini-Pic display defaults to normal, full colour mode. When using OmniTek XR 
in a colorist environment, where brightly coloured displays can be a distraction, it 
may be helpful to switch the Mini-Pic into the monochrome mode. 

The Mini-Pic can also be switched into a blue or green mode, whereby the blue (or 
green) data is applied to all three channels. This can be very helpful in looking for 
noise or for macroblocks, which tend to be more pronounced in chroma channels 
than in luma channels, especially in HD. 

Show Closed Captions 

This option is for use where the incoming material (or test sequence) contains closed 
captions or teletext subtitles in any of the supported formats. ‘Line 21’, EIA-608 and  
OP-47 teletext are supported as standard. EIA-708 captions can be displayed on systems 
that include the 708 Decode option.  

   The type of caption must first be selected either by taking the Closed Caption Source 

option below or by using the equivalent option in the main Analyzer menu (see page 17). 
For teletext subtitles, it is also essential to set the necessary page/line details on the 
Teletext: Reader page of the Engineering Settings control window (page 29). Additional 
settings are also required where ‘Line 21’ captions are delivered in a video format other 
than NTSC and on a line other than Line 21 (see page 30).
