Please be aware that power restrictions will not allow you to fill a frame to full capacity with Up-and-down-AAFD. If you wish to use all frame slots, please mix them in a frame with lower-powered boards

VIDEO INPUT
One HD or SD input with reclocking
270Mbit or 1.485Gbit serial compliant to EBU 3267-E, SMPTE 259M and SMPTE 292M
HD cable equalisation up to 140m with Belden 1694 or equivalent (approx. 100m with Belden 8281). SD cable equalisation >250m Belden 8281 or equivalent

VIDEO OUTPUTS
Two HD or SD scaled outputs using RM34 frame rear module
Two equalised and reclocked input loop-throughs
Auto detection of input standard will ensure the output is always in the desired format, whatever the input

INPUT TO OUTPUT CONVERSIONS
Up conversions:
625/50 to 720p50
525/59.94 to 720p59.94
625/50 to 1080i50
525/59.94 to 1080i59.94

Down conversions:
720p50 to 625/50
720p59.94 to 525/59.94
1080i50 to 625/50
1080i59.94 to 525/59.94

Cross conversions:
720p50 to 1080i50
720p59.94 to 1080i59.94
1080i50 to 720p50
1080i59.94 to 720p59.94

PICTURE PROCESSING
Pixel based motion adaptive de-interlacing means that Up-and-down-AAFD 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
Colour space conversion from SD Rec. 601 to HD BT. 709
RGB gain and dc offset adjustments allow control of the image brightness, contrast and colour

ASPECT RATIO CONVERSION (HD TO SD OR SD TO HD)
HD is always 16:9. SD may be 16:9 or 4:3. When converting up or down the aspect ratio of the picture may therefore need to be changed

The available aspect ratio conversions for HD to 4:3 SD are:
Full image: 16:9 to 4:3 Letterbox (the full 16:9 source with horizontal black bands)
Fill screen: 16:9 to 4:3 Full Screen (a centre cut with left and right of the picture lost)
Compromise: 16:9 to 14:9 Letterbox (slight picture loss on left and right and thin horizontal black bands)
Anamorphic: the whole input picture fills the whole output image and is distorted

The available aspect ratio conversions for 4:3 SD to HD are:
Full image: 4:3 to 16:9 Pillarbox (the full 4:3 source with vertical black bands)
Fill screen: 4:3 to 16:9 Full Screen (a centre cut with top and bottom of the picture lost)
Compromise: 4:3 to 14:9 Pillarbox (slight picture loss on top and bottom and thin vertical black bands)
Anamorphic: the whole input picture fills the whole output image and is distorted

ASPECT RATIO CONVERSION (SD TO SD)
When the input and output are both SD, Up-and-down-AAFD can be used as a fully flexible 10 bit aspect ratio converter
Has presets for the six standard conversions to put a 16:9 source on a 4:3 monitor, or a 4:3 source on a 16:9 monitor. The available presets are: 16:9 to 4:3 Letterbox, 16:9 to 14:9 Letterbox, 16:9 to 4:3 Full Screen, 4:3 to 16:9 Pillarbox, 4:3 to 14:9 Pillarbox and 4:3 to 16:9 Full Screen. It is also possible to select no conversion with the same delay
Custom aspect ratios can be created with vertical and horizontal picture size adjust of + or - 100 lines and pixels and vertical and horizontal picture offset of + or - 100 lines and pixels
Vertical and horizontal cropping allows up to 31 lines to be cropped from the top and bottom of the picture and up to 31 pixels from the left and right
Closed captions on line 21 in 525 line can be passed
Widescreen signaling on line 23 in 625 line can be passed or blanked

BYPASS MODE
To maintain the best picture quality the Up-and-down-AAFD 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

DELAY THROUGH BOARD
One video frame

ACTIVE FORMAT DESCRIPTION
Up-and-down-AAFD will insert SMPTE 2016 picture aspect ratio data into the output video for aspect ratio correction by downstream equipment

EDH
EDH insertion to SMPTE RP165 and SMPTE 292M

EMBEDDED AUDIO HANDLING
Four audio groups can be detected in the video input
The two lowest numbered audio groups are de-embedded then re-embedded on the output

LED INDICATION OF:
SD/HD input or input not present
