Standard Crystal Vision module 266mm x 100mm
With DA6 top board fitted: 'Double decker' module 266mm x 100mm (uses two frame slots)
Weight: 180g; 240g with DA6 fitted
Power consumption: 11.9 Watts (plus 3 Watts for DA6 and 0.6 Watts for FIP or FOP)
INTEGRATED FIBRE OPTIONS
Up-Down-AS 3G can be given integrated fibre connectivity by fitting either the FIP fibre input option or FOP fibre output option. The chosen option should be fitted at the factory
To access the optical inputs or outputs an RM57 frame rear module must be used
When fitted with a FIP or FOP, Up-Down-AS 3G can be housed in any frame slot position but due to its extra height it is not possible to place Standard Definition or audio boards directly above it when the Up-Down-AS 3G is in even numbered slot positions. 3Gb/s and HD boards do not share this restriction. If a DA6 top board is also fitted, this positioning restriction does not apply
FIP and FOP meet the SMPTE 297-2006 short-haul specification, allowing operation with single-mode and multi-mode fibre

VIDEO INPUT
One 3Gb/s, HD or SD input with reclocking
When using FIP fibre input option allows selection between one optical and one electrical input
270Mb/s or 1.5Gb/s or 3Gb/s serial compliant to EBU 3267-E, SMPTE 259M, SMPTE 292M and SMPTE 424M
3Gb/s cable equalisation up to 80m using Belden 1694A. HD/SD cable equalisation up to 140m with Belden 1694A or equivalent (approx. 100m with Belden 8281)
Input return loss: -15dB for 50MHz to 1.5GHz and -10dB for 1.5GHz to 3GHz
VIDEO OUTPUTS
Up-Down-AS 3G can perform two different conversions at the same time, making it easy to create HD and SD copies of a feed. Each output will either be converted from the input or given a matching delay to ensure they remain co-timed
There are two output groups, A and B. The A-B matrix control allows the user to select whether an output group will be either SD or 3G/HD. The output groups can be configured as either:
A=SD and B=SD
A=3G/HD and B=3G/HD
A=SD and B=3G/HD
A=3G/HD and B=SD
If High Definition is selected for any group, the HD format control will determine the output format (720p, 1080i or 1080p). If Output A and Output B are both selected as 3G/HD, the outputs will be identical
Once set the output selection will remain true, irrespective of any change in the input standard
Should the input format change, Up-Down-AS 3G will reconfigure itself cleanly in a single frame blanking period
Using RM41 rear module: Two co-timed outputs, with two feeds of Output A and three feeds of Output B
Using RM57 rear module with FIP fibre input option: Two co-timed outputs, with one feed of Output A and three feeds of Output B (select between one fibre and one electrical input)
Using RM57 rear module with FOP fibre output option: Two co-timed outputs, with one feed of Output A and three feeds of Output B along with a copy of Output B on fibre
Outputs can be individually configured as either 3G/HD or SD. If outputs are both selected as 3G/HD, the outputs will be identical
If a DA6 top board is fitted, the Up-Down-AS 3G will also output six reclocked loop-throughs of the 3Gb/s, HD or SD input. In this case Up-Down-AS 3G will use two frame slots and the RM41 or RM57 rear modules need to be used with an RM34 to create a 'double height' rear module
Output frame rate same as input frame rate
PICTURE PROCESSING WHEN UP AND CROSS CONVERTING
Pixel based motion adaptive de-interlacing means that Up-Down-AS 3G will automatically chose the best processing method based on the video content. In video containing significant movement the output picture will look natural and smooth
Adjustable detail enhancement allows the user to sharpen the edges in the image, reducing the perceived softness of an up converted image. Fine Detail Enhancement applies sharpening to the entire image, while the Edge Enhancement applies sharpening only to object edges
Noise reduction is available and can be used to ensure that MPEG encoders do not waste unnecessary bandwidth on detail that is not really part of the picture
RGB and YUV lift and gain controls allow independent digital image adjustments in both the RGB and YUV domains
PICTURE PROCESSING WHEN DOWN CONVERTING
Up-Down-AS 3G uses Crystal Vision's proprietary down conversion, which avoids aliasing while retaining picture sharpness
Sophisticated two dimensional filtering gets broadcast results and avoids the complication of looking at multiple fields or movement detection, resulting in reliable, artefact-free conversion with broadcast filter quality
When down converting the performance can be optimised by choosing one of four alternative vertical filter characteristics (sharpest, sharp, soft, softest)
RGB and YUV lift and gain controls allow independent digital image adjustments in both the RGB and YUV domains
BYPASS MODE
To maintain the best picture quality the Up-Down-AS 3G will automatically enter a bypass mode when the input is the same as the selected output standard, bypassing the major processing blocks and adding a matching delay
TIMING ADJUSTMENTS
There are two synchronisers downstream of the converter, one in the 3G/HD path and one in the SD path - means Up-Down-AS 3G can give a clean output in two different formats even when the input standard changes
Up-Down-AS 3G takes its timing from the analogue external reference and will automatically synchronise sources between 0 and 1 frame
Cross-locking allows a 3Gb/s, HD or SD source to be referenced to either HD tri-level syncs or SD Black and Burst
Full vertical and horizontal timing adjustment between 0 and 1 frame, independently adjustable on each synchroniser
DELAY THROUGH BOARD AND VARIABLE VIDEO DELAY
Minimum delay of one video frame less 16 lines
On top of the minimum delay, a variable video delay of up to one frame plus 16 lines, adjustable in lines and pixels, allows it to compensate for video delays generated by other equipment (maximum delay is therefore two frames in total)
ASPECT RATIO CONVERSION
The following standard aspect ratio conversions are available when up converting from SD to HD or 3Gb/s: 16:9 Anamorphic (for 16:9 SD systems) and either 4:3 to 16:9 Pillarbox, 4:3 to 14:9 Pillarbox compromise or 4:3 to 16:9 Full Screen (for 4:3 SD systems)
The following standard aspect ratio conversions are available when down converting from 3Gb/s or HD to SD: 16:9 Anamorphic (for 16:9 SD systems) and either 16:9 to 4:3 Letterbox, 16:9 to 14:9 Letterbox compromise or 16:9 to 4:3 Full Screen with centre cut (for 4:3 SD systems)
The eight standard aspect ratios can be adjusted from their default values by using independent sets of size, position and crop controls:
Vertical and horizontal picture size adjustment: continuous adjustment of appoximately +/- 25% of nominal image size
Vertical and horizontal picture position adjust +/- 50%
Vertical and horizontal picture crop adjust +/- 100% of picture size
Copes with both analogue and digital SD blanking widths. When analogue blanking width is selected, the Anamorphic conversion uses 702 pixels of SD (rather than 720 pixels) to create the 1920 pixels of 1080i or 1080p, and all other aspect ratios are adjusted by a similar amount
EMBEDDED AUDIO PASSING
De-embeds and re-embeds the first four numbered audio groups
Bypass: Audio bypassed in HANC space, with the same delay as the video
VIDEO SIGNAL CHECKS
Checks can be performed on four video parameters, with warnings of any problems provided via Statesman alarms or SNMP traps
The video parameters are: input missing, video black, video frozen and input incompatible
The video black and video frozen parameters can be delayed before an alarm is asserted to prevent false alarming during brief video pauses
AUDIO SIGNAL CHECKS
Checks can be performed on nine audio parameters, with warnings of any problems provided via Statesman alarms or SNMP traps
The audio parameters are: input audio missing, silence group 1 channels 1 and 2, silence group 1 channels 3 and 4, silence group 2 channels 1 and 2, silence group 2 channels 3 and 4, silence group 3 channels 1 and 2, silence group 3 channels 3 and 4, silence group 4 channels 1 and 2 and silence group 4 channels 3 and 4
All parameters can be delayed before an alarm is asserted to prevent false alarming during quiet audio periods
BASIC TIMECODE TRANSPORT
Can pass Ancillary Timecode from the input to the output
The Ancillary Timecode can be used to get the interlace timing correct and maintain a correct field sequence when down converting from 1080p or 720p to an interlaced output
