Video Adjustments
The digital Video processing provides adjustment for; Brightness, Contrast, Saturation and Hue.
Time Stamping*
Processes External VANC extracted UTC#1 and SMPTE-12M time stamps from the digitized Video stream
input of the HD-SDI/SDI input interface. The secondary UTC#2 is also generated using an external 1PPS signal
and EIA-232/422 serial configuration commands.
Key Length Value (KLV)
Implementation of the KLV Metadata meets standards set by the National Geospatial-Intelligence
Agency (NGA) Motion Imagery Standards Board (MISB). The KLV Metadata is input into the M2ECHPT either
via embedding it in the VANC space of the HD-SDI/SDI input interface and/or the separate serial RS-422
interface.
Time Stamp Processing*
The Picture Timing SEI messages allow each Video frame to be assigned a time value. This time can represent
time of origin, capture or alternative ideal display. As such, it can be used to navigate to a frame with a
particular time.
The H.264 format, specified in ISO/IEC 14496-10 provides for an optional time stamp to be defined in the
Supplemental Enhanced Information (SEI) message. The picture timing SEI message (pic timing) specified
HH:MM:SS:FF IAW RP 0604 page 5. Additionally, the standard allows for
a particular Video frame using the
stamp UTC#1 is inserted into the pic timing SEI element of the NAL packets in the H.264's output stream. The
secondary M2ECHPT time stamp UTC#2 is a 64 bit value indicating the number of microseconds since August
rd
23 1999 and is inserted into the unregistered user data SEI element.
