HD-SDI Video Inserter/Recorder
2.0 GENERAL
The Model 6520 integrates the overlay, timing and metadata insertion capabilities of a 6055C-nGHD with
the capability of recording uncompressed video to volatile DDR3 or a non-volatile solid state disk (SSD).
Features include:
Accepts SD, HD and 3G SDI video sources per SMPTE 259M/292M/424M
Auto-detects and formats insertion for 480i, 576i, 720p and 1080i/p for both NTSC and
PAL field/frame rates
Records continuously to SSD (1TB) up to 172K Frames 1080p/60 Uncompressed
Event/Loop record up to 5.8K Frames 1080p/60 Uncompressed
Save more than 32 event clips to SSD
Live Monitor Video while recording
Plays back HD-SDI
Inserts, decodes and can overlay MISB 0605.3 format compliant timestamp and up to 2
SMPTE 291M Type 02 KLV metadata packs of user formatted data in VANC space
1
Inserts up to 3000 characters of alphanumeric data on each video frame
Inserts movable and fixed boresite crosshairs independently in color.
HD-SDI playback speeds: 1/32x-1x slow motion, single-frame stepping, or search 2x-32x
Extracts data of KLV metadata to Ethernet data file frame x frame with/without timestamps
Clear DDR3 and/or SSD compliant with DOD 5220.22-M
Camera Sync (optional); GPS/IRIG phase locked with adjustable offset
TTL strobe aligned with Camera Sync with adjustable delay
Disciplined Stratum 3 (Optional) clock delivering < 5µs/hr unlocked drift
Synchronizes time to within 25±20 ns of the GPS time mark generated by an internal 12
channel GPS receiver or 5±3µs of and applied IRIG.
Samples time to 3±2µsec of any vertical sync (EAV) detected in the SDI video stream.
Inserts time as collected from GPS, IRIG or read from previously recorded metadata in a
selectable resolution from 1second to 1µs.
Records collected time to a 1 µs resolution into the MISB Microsecond Timestamp when
processing 720 and 1080 formats
Remotely controlled via Ethernet port by commands, ITS GUI or embedded webserver.
There are four modes of recording possible; Event Record (ER), ER and-save event clips to SSD, event
record to DDR (pre-event) and SSD (post event) or Continuous Record to SSD. An internal DDR3
facilitates ER where 6520 can be set to continuously record incoming HD-SDI video in a “loop”. The loop
length is programmable from 10 frames to the capacity of the DDR3. When in ER mode, the recorder will

6520 Inserter-Recorder Operation Manual Page 3
continuously record the number of frames set by the user (up to 26,000; 480i). On trigger, either a discrete
input or command via Ethernet, the recorder will continue to record the number of post event frames
previously specified by the user. The result is a clip surrounding the event. Another event mode will
continuously record to the loop length as before, but when the event is marked, the entire loop as recorded
prior to the event marker will be saved to SSD and recording will continue until a STOP is commanded or
the capacity of the SSD is exhausted. The clip may played back and presented as SDI to the output video
port. Event recording has many benefits including the capture of important video sequences with a
minimum of control input and highly efficient use of the SSD capacity.
The 6520 includes a live monitor channel that is active while recording. Video presented at this port while
recording is less than 8µsec behind real time. The live monitor channel includes a metadata decoder and
overlay engine. These capabilities enable one to monitor not only the video, but the data being captured in
the metadata. The record and playback channels have the capability to independently overlay text, time and
crosshairs.
The 6520 records and plays back all HANC (payload, AES audio and other metadata) and VANC metadata.
Text and crosshairs may be overlaid at record time. More importantly MISB format metadata timestamps
and up to two user defined KLV metadata packets may be recorded with each frame1. At playback the
metadata may be decoded and overlaid if desired and concurrently extracted to the Ethernet port as a data
stream. This data set may include the timestamps permitting exact identification of the frame with which
each block of data was collected.
During any playback, the video may be stopped, played back 1 frame at a time or at 1/32xFR to 1xFR in 32
in either direction where FR is the original frame rate of the recorded video. Search may also be
accomplished at 2xFR to 32xFR in either direction. Playback speeds greater than the originally recorded
frame rate is accomplished by frame skipping.
Metadata packs are SMPTE 291M type 02 structures the content of which may be designed using ITS KLV
SOFTWARE TOOLKIT or software supplied by others. The ITS toolkit is currently delivered at no
additional cost with all of our HD-SDI video products having the KLV capability.
Source video may be 720p or 1080p at 25, 30, 50 and 60 frames/sec (also at the NTSC comparable rates).
Source video may also be 480i/60 or 1080i/60 also at the NTSC comparable rates. Frame formats supported
comply with SMPTE 274M (1080) SMPTE 296M (720) and SMPTE 125M (480); ITU 709 10-bit 4:2:2
sampling. The 6520 will detect the format and synchronize to any of these formats automatically. No user
intervention is required. Clips may be of different formats as well.
When the camera sync option is purchased, the 6520 may be programmed or if the camera always outputs
SDI, will auto detect the camera format (must be one of the supported formats) and set the tri-level sync
(TLS) to match. TLS may be phase locked to either GPS or IRIG. TLS may also be delayed in 1µsec steps
to 32 msec in order to synchronize actual picture taking across a variety of imaging technologies (e.g. CCD,
CMOS, IR). Supporting data collection time coherent to imagery, the camera sync option also provides a
TTL strobe output that may be adjusted ±16ms in 1µ steps to help align data acquired with each image.
The 6520x-NN may be ordered in a shelf mount or 19” 2U rack mount enclosure. Input power
may also be specified at order to support 10-36 VDC (power adapter is available), or by 100 to
240VAC 50/60 Hz.
