MECHANICAL
'Double decker' Crystal Vision module 266mm x 100mm
Weight: 300g
Power consumption: 16 Watts

VIDEO STORE
4 GB multi-port video store
Moving HD video: Clip N Key can store approximately 30 seconds in 50Hz (15 seconds with key signal) and approximately 25 seconds in 59.94Hz (12 seconds with key signal)
Moving SD video: Clip N Key can store approximately 150 seconds (75 seconds with key signal)
Can store any number of clips, dependent on total length of time used
Can read and write multiple images at once
Flash store retains video data when board is unpowered

VIDEO INPUTS
Up to two HD or SD inputs for clip or sting with optional key signal
270Mbit or 1.485Gbit serial compliant to EBU 3267-E, SMPTE 259M and SMPTE 292M
HD cable equalisation up to 140m with Belden 1694A or equivalent (approx. 100m with Belden 8281). SD cable equalisation >250m Belden 8281 or equivalent
Input return loss: -15dB for 50MHz to 1.5GHz
Auto 50/59.94Hz and video format selection

ANALOGUE REFERENCE
The output can be locked to an SD Black & Burst or HD tri-level syncs analogue reference

VIDEO OUTPUTS
One HD or SD clip output and one key output using RM52 and RM34 frame rear modules together
Relay bypass protection of the main input
Serial output: 270Mbit or 1.485Gbit serial compliant to EBU 3267-E, SMPTE 259M and SMPTE 292M. Output follows the input format

GRAPHICS SOFTWARE AND TRANSFER
Special drag-and-drop software running on the graphics PC will convert most common graphic file formats to the format required by Clip N Key
Can work with both named images and reference by timecode
100 MB Ethernet connectivity from the graphics PC straight into the video store on the board for fast transfer of clips and stings

TRIMMING OF RECORDED VIDEO CLIPS
The dedicated software can be used to step through a clip frame by frame by using the "Next" and "Previous" controls and set mark in and mark out points for the clip. The "Trim" control can be used to remove the unwanted section from the clip or the selection can be cancelled

DELAY THROUGH BOARD
The input has a one-line TBC to align the input signal timing
SD delay: 6.5us min - one line plus 6.5us max
HD delay: 1.7us min - one line plus 1.7us max
Output timing can be from either an analogue reference or the input, with a user offset

AUDIO
Audio data is transferred to and from the board via Ethernet using the PC drag-and-drop software. A single audio group can be embedded into the video outputs. Audio routing of the stereo pairs allowing selection of which of the possible sources are embedded. Audio can be played out separately, or audio and video ports can be locked together so files can be played out at the same time - allowing clips to have accompanying audio
Clip N Key can also be used as an audio clip player

GPI INPUTS
Three GPI inputs can recall one of seven presets
Active: pull to ground, pulled up to +5V through 10 kohm
The GPIs are shared with the second serial port (link selection)

GPI OUTPUTS
One GPI output
Other GPI output connection is used to control the bypass relay
Electrically: Open collector transistors 48V, 270 ohm current limit resistors. Pulled up to +5V through 6800 ohm

LED INDICATION OF:

SD/HD input

LOCAL CONTROL
Board edge with ten character alphanumeric display

REMOTE CONTROL
RS422/485
Port 1: 19200 baud, 8 bits, 1 stop no parity
Port 2: 38400 baud, 8 bits, 1 stop odd parity
Basic control from frame active front panel and remote panel
Statesman allows basic control from any PC on a network
SNMP monitoring and control available as a frame option
Clip N Key runs the uCLinux operating system
Second serial port (link select instead of GPI inputs) allows connection to control panels and automation systems
Industry standard software protocols help it to work with automation systems and video mixers
VTR protocol can be used to record and play clips using timecode labels
RM52 frame rear module includes dedicated RJ45 connector for RS422 control
