OmniTek 2.3 User Manual

•  Luminance Content 

This control works in exactly the same way as the Motion Content control, and detects if 
the picture is black. 

•  Chrominance Content 

This control works in exactly the same way as the Motion Content control, and detects if 
the picture is black and white. 

The results of these detectors are displayed in the Video Status window, described on 
page 84 of this manual. These same detectors may also be used in the logging or in 
SNMP alerts, as described in the section starting on page 104. 

OmniTek XR is able to read and display VITC, LTC and ATC time codes. 

 

 

There are important differences between the three types of time code and hence in how 
they are handled. LTC time codes use a dedicated feed. VITC time codes are embedded 
in the video data stream (SD only). ATC time codes are packets in either SD or HD video 
containing either LTC, VITC #1 or VITC #2 data. 

To read ATC packets, the reader needs to know the type of time code contained within 
the time code packets. 

To read VITC time codes, the reader needs to know which lines the VITC time code data 
is to be read from. The Link Fields option makes entering this data easier by 
automatically setting the Field 2 value from the Field 1 value. The typical lines used for 
PAL and NTSC are shown in the above screen dump.  

To display LTC time codes, OmniTek XR needs to be fitted with an LTC reader. At the 
time of writing, the only LTC reader to be supported is the Miranda “Little Red” which 
feeds the LTC to an RS232 port (available from your OmniTek dealer). The presence of 
the reader (when fitted) is detected automatically and shown in this dialogue.
