A unique solution to picture squeezing

LKEY-SQZ is a unique product offering the highest quality picture squeeze and picture-in-picture effects combined with flexible keying – all in a low-cost modular product.

Squeeze end creditsWorking with 31 different video standards, this squeeze back keyer is ideal for any applications where the programme needs to be resized or repositioned for another layer of video to be displayed – such as squeezing the end credits to preview the next programme, squeezing a presenter to allow room for additional graphic material, or picture-in-picture type applications such as news interviews.

You'll get the highest quality picture squeeze from this dedicated product. With eight example scenes included, sophisticated moves can easily be pre-built and then triggered manually or via automation systems.

Squeezing the picture

By including a simple DVE, LKEY-SQZ can smoothly resize the main video both horizontally and vertically, reposition it on the screen and put it inside another input or coloured border. The border is a moveable rectangle filled by a specific matte generator which lies behind the squeezed video in the layering and is most useful for picture-in-picture applications.

Graphics or text generated by an external device can then be keyed on top of and around the squeezed picture, with the option of filling the background area with a matte colour after the video has been squeezed. The video can transition back to full size or to another size or position as required.

The highest quality picture squeeze

It's the quality of the picture squeeze that makes LKEY-SQZ special. It uses sub-pixel processing, an excellent de-interlacer and an advanced algorithm to ensure extremely smooth movement from one size to another. This is particularly important on moving text which can be very demanding – LKEY-SQZ will ensure there is no distortion to the text during the picture squeeze.

It is also possible to adjust the filtering used on the squeezed image to optimise the effect, trading image sharpness against aliasing artefacts.

Keying

LKEY-SQZ allows the key to be generated in two different ways. External Key mode uses the luminance of the signal on the Key/Video B input to key a graphic on the Video A input over the background, while Self Key mode uses the luminance value in the graphic on Video A input to generate the key. LKEY-SQZ offers both additive and multiplicative linear keying, allowing you to choose a method to suit the graphics.

Key gain, offset and opacity controls allow the intensity of the key to be adjusted.

Two internally-generated rectangular masks – adjustable in position and size – can be used to force areas of video which may otherwise be hidden by the key layer. Adjustable edge softness is useful for blending between masked and unmasked areas for a more natural-looking mask edge.

Flexible fading

The key layer, squeezed video layer, bypass layer and border layer can each be faded up and down under timeline control. LKEY-SQZ can also be used to fade the complete programme to black if required.

Timing your signal

Line synchronisers will correct incoming signals up to one line apart in timing, with the output video timed to either one of the inputs or to an external SD Black and Burst or HD tri-level syncs analogue reference.

You can easily compensate for mistimed sources elsewhere in your system by adjusting the output timing relative to the reference through an entire frame using horizontal and vertical settings.

Select your output audio

View the scenesLKEY-SQZ is easy to use in a system with embedded audio. The audio selected for embedding into the output video can be taken from any of the inputs.

Alternatively all ancillary data including embedded audio can be blanked.

Working with scenes and timeline control

LKEY-SQZ can perform a sequence of operations – known as a 'scene' – using full timeline control of events. Timelines are a key part of LKEY-SQZ operation, with a timeline having five segments (delay, in, dwell, out, wait) and starting when it is triggered. Events can be timed in relation to each other as well as to the start of the scene.

With eight example scenes included, sophisticated moves can easily be pre-built and then triggered manually or via automation systems. The example scenes can be changed by editing nine XML files. The files themselves are simple because each file describes only one element and they can be edited using a basic text editor.

View the eight example scenes by downloading the brochure or watching the video.

The five layers on LKEY-SQZ are background, border, squeezed video, bypass path and downstream keyer, with layer priorities set using VisionWeb. Squeeze position, size, rate of movement and key fade rate can all be adjusted. The timeline XML files can be uploaded directly into the LKEY-SQZ board via FTP thanks to the dedicated Ethernet connector on the RM77 rear module.

Control options for LKEY-SQZ include board edge switches, an integrated control panel on the front of the frame, the VisionPanel remote control panel, SNMP or the VisionWeb web browser control. Try the LKEY-SQZ VisionWeb demo...

GPIs can be used to take a scene in or out and to trigger up to eight of the presets. 40 presets are available in total and are ideal for holding information on the static state of the device such as layering priority and key gains.

Save rack space - and protect your output

Crystal Vision frameLKEY-SQZ is a 100mm x 266mm board which fits in the Indigo frames (available in 2U, 1U and desk top box sizes) and saves you rack space by allowing up to six squeeze back keyers to be housed in 2U.

The Video A, Key/Video B, Squeeze Video and analogue reference inputs, one main output and one auxiliary output are accessed by using the dual height RM77 frame rear module. The RM77 additionally provides relay bypass protection of the squeeze video on power failure or board malfunction or removal.

DELAY THROUGH BOARD

SD: 85us min

HD: 18us min

3Gb/s: 10us min

TIMING ADJUSTMENTS

Reference timing can be selected to come from any of the video inputs or from SD Black and Burst or HD tri-level syncs. 3Gb/s, HD or SD source can use either type of reference. When cross-locking it is necessary for both the video input and reference to share the same frame rate

A line synchroniser on each input will automatically synchronise sources up to one line apart in timing for automatic correction of timing errors

Compensate for mistimed sources elsewhere in system by adjusting output timing relative to the reference through an entire frame using horizontal and vertical settings

Amplitude of syncs 150mV to 600mV

Link on PCB selects 75 ohm termination or high impedance

The delayed squeeze input is a non-squeezed version of the squeeze input which is delayed by the same amount as the squeezed video, allowing a switch away from a full-screen squeezed image to a completely unprocessed signal without a timing jump

PICTURE SQUEEZING

LKEY-SQZ includes simple DVE that can smoothly resize video horizontally and vertically and reposition it on the screen allowing another layer of video to be displayed

Can put video inside another input or coloured border (see BORDER section)

Can transition back to full size or to another size or position as required

Top quality video squeeze using smooth sub-pixel processing, motion and edge adaptive de-interlacer and advanced re-interlacing algorithm

KEYING MODES

Graphics or text generated by external device can be keyed on top of and around the squeezed picture

External Key mode uses luminance of signal on the Key/Video B input to key a graphic on the Video A input over the background, while Self Key mode uses luminance value in the graphic on Video A input to generate the key

Key processing can be additive or multiplicative

External Key controls: Enable, Multiply/Additive, Invert, Min Clip, Max Clip

Self Key controls: Enable, Multiply/Additive, Invert, Min Clip, Max Clip

The key can be made to have a semi-transparent effect by using areas of grey in the external key signal, by using the Min and Max Clip controls or by using the fade controls

Keyer FG control selects what is used as the fill when an external or self key is enabled

Keyer crop controls define an area for which an enabled external or self key is shown

PICTURE FILTERING

It is possible to adjust the filtering used on the squeezed image to optimise the effect, trading image sharpness against aliasing artefacts

H and V controls adjust how sharp the squeezed image looks, with a softer picture causing less flickering in moving areas of fine detail

The de-interlacing filters can be used to reduce flickering in the image in areas of fine detail due to de-interlacing and re-interlacing processes, following image scaling changes

INTERNAL MASK GENERATOR

Masks can be used to force areas of background or foreground video which may otherwise be hidden by a key layer

Two internal masks available (Foreground and Background) which can be turned on or off, inverted to force keying outside an area and adjusted in position and size. Masks have edge softness controls to prevent hard edge on mask, with each edge individually selectable

Foreground and Background mask controls: Enable, Invert, Mask Window: Left/Right/Top/Bottom edges adjustable from 0 to 100% (to set mask size and position), Mask Softness: Left/Right/Top/Bottom edges adjustable from 0 to 100%

The External Key signal can also be enabled as an External Mask, to force the background through a self key. Controls are: Enable, Multiply/Additive, Invert, Min Clip, Max Clip

INTERNAL MATTE GENERATOR

Three separate matte generators available

Background matte is one option for the background

Foreground matte is one option for the keyed foreground video source, allowing a selectable flat colour to be put in the keyed areas

Border matte defines the colour used for the border layer – a rectangle that can be moved, scaled and faded on the basis of the scene timeline

BORDER

The border is a moveable rectangle filled by a specific matte generator which lies behind the squeezed video in the layering. The typical use will be to size and move this in combination with the squeezed video to provide a border that visually separates the squeezed video from the background, such as for picture-in-picture applications

FADES

Each layer can be faded up and down under timeline control:  Key layer, Squeezed video layer, Bypass layer and Border layer (NB. Background layer cannot be faded)

Fade programme to black on main and auxiliary outputs

EMBEDDED AUDIO

Embedded audio is taken from any chosen input, allowing selection of audio from either the Video A, Video B/Key or Squeeze Video input to output with the final video

All ancillary data including embedded audio can be blanked

SCENES AND TIMELINE CONTROL

Timeline control is used to perform a sequence of operations (a 'scene') relative to a start signal. Multiple scenes can be programmed, allowing quick selection of different moves. Events can be timed in relation to each other and not just the start of the scene

LKEY-SQZ has 16 built-in example scenes. Scenes 9-16 are a carbon copy of scenes 1-8 and provide a backup of the original. Scenes 9-16 will remain as default until a user changes them and will not reflect any changes made to scenes 1-8. See pages four and five for description of built-in scenes

Possible objects in each scene are bypass (top, hides everything else if faded up), squeezed video, border, keyed video and background (anything appears on top of this)

Layering control is set using VisionWeb, with layer 1 appearing in front. When set to 'Squeeze over keyer', object priorities are: 1. Bypass;  2. Squeeze;  3. Border;  4. Keyed video;  5. Background. When set to 'Keyer over squeeze', object priorities are: 1. Keyed video;  2. Bypass;  3. Squeeze;  4. Border;  5. Background

Example scenes can be changed by editing nine XML files. The files themselves are simple because each file describes only one element and they can be edited using a basic text editor. The XML files define the priority and triggering relationships between the layers, the timeline for each layer (in, dwell and out times and the size, position and alpha parameters for each object at each static state) and the colour, size and default position of the unprocessed object

A timeline consists of five segments: delay, in, dwell, out, wait. Each segment can have a time, defined in milliseconds from zero to one hour. If dwell time is not defined it is treated as infinite and timeline will stay in dwell state until scene is taken out or until a triggerout event occurs

There are parameter values (scale, position and alpha) at each static segment (delay, dwell and wait),  with the position and scaling of the object defined in percentages of the screen size for position and default size for scaling. The value of parameters during 'in' and 'out' is linear ramp between the relevant static values

Squeeze setup on VisionWeb allows the effect to be previewed in a static way, allowing settings to be tested before they are added to the XML files

FTP timeline files directly into LKEY-SQZ board using dedicated Ethernet connector on RM77 rear module

PRESETS

The current board settings can be saved in one of 40 locations to be recalled as required

Presets store the entire state, including the selected scene, and are ideal for holding information on the static state of the device such as layering priority and key gains

GPI INPUT LEVELS

Active: pull to ground, pulled up to +5V through 10 kohm

GPI INPUTS

Six GPI inputs

Three are used for the recall of up to eight presets

One is used to take the scene in

One is used to take the scene out

One acts as a tally when the scene is in

LOCAL CONTROL

Intuitive board edge interface with two select buttons, shaft encoder and ten character alphanumeric display

REMOTE CONTROL

Control from integrated control panel on AE frames and remote panel

VisionWeb Control is available via the web server on the frame and allows operation using a standard web browser on a PC or tablet

SNMP monitoring and control available as a frame option
