Spotlight #15 - HD-SDI Video

Are you working with HD-SDI video ?   If so, please read on.

We now have some new stand-alone compact products for inserting time and data extremely accurately into high definition (HD) serial digital interface (SDI) video streams.

The time stamps may be inserted into the visible part of the images, or encoded to within 1 microsecond accuracy in the (non-visible) VANC metadata in compliance with STANAG 4609.   Our method of encoding the time in KLV packets of VANC line 9 complies with the MISB 605.3 standards.

In addition we offer the ability to insert data (up to 4.6 MBytes/sec for a 60 frame per second 1080p stream) into the "metadata" area of the video frames.   For instrumentation applications this means that a HD-SDI video recorder may also act as a data recorder when used with our HD-SDI video inserters.

The time inserters are accurate to within 100 nanoseconds of the GPS time.   This allows them to be used as a time reference, even over large distances at remote locations.   If HD-SDI video is encoded and transmitted via one 6980G-HD and then read at another location using a second 6980G-HD the latency of the transmission may be measured to an accuracy of +/- 5.2 microseconds.

Our HD-SDI time code inserters will automatically detect and synchronise to 1080p, 1080i, 720p, and 480i signals, be they NTSC or PAL.
