EZwindow Video Combiner

EZwindow Video Combiner

The EZwindow™ video combiner converts analog or digital video from multiple inputs into a common, synchronized output format, and then combines the video or blends video in one of a variety of user defined methods. Special attention has been given to minimize latency, while achieving broad area-of-interest control on inputs and outputs. In addition, EZwindow™ supports video overlays for specialty simulation applications.

EZwindow

Configured with 2 to 5 inputs combined into 1 output. Each EZwindow™ input channel can accept video in one of many formats, including: DVI-I (TMDS and analog RGB), RS-343, RS-170, NTSC, PAL, STANAG. The EZwindow™ can combine multiple inputs and support up to 2560×1600 resolution (dual link DVI) output.

EZwindowHR

Accepts up to (5) standard video inputs (Up to WUXGA) along with (1) dual link DVI input, combining the inputs into one dual link video output. This device enables dual link DVI monitors and projectors (eg 2560 x 1600) to be used in multi-window applications. Each standard input channel can accept video in one of many formats, including: DVI-I (TMDS and analog RGB), RS-343, RS-170, NTSC, PAL, STANAG. The dual link DVI input can accept DVI single link, DVI dual link, and analog RGB.

Features

• Alpha blend, RGB Key, HSV Key, Luma Key, windowing, split screen, PIP, programmable borders, and more

• Supports up to 2560×1600 dual link DVI displays. EZwindowHR™ supports dual link DVI input

• Output resolution and timing is completely independent of input timings. User-definable area-of-interest (AOI) within each input, mapping of the AOI onto the output resolution, and output content definition (how to combine the output streams)

• RoHS Compliant

Applications

• Combining multiple display images into a single instructor operator station (IOS) monitor feed in training and simulation environments

• Combining multiple desktop images in educational applications

• Any application that combines multiple video sources in real-time, with minimal latency and minimal video artifacts

Alpha Blend

Two video sources are mixed per a user defined ratio. This is the most common video blending technique.

RGB Keying

Two video sources are mixed, based on RGB content of one of the video sources. Allows Up to (4) different levels of mixing based on If-Then-Else logic statements for RGB content.

HSV Keying

Two video sources are mixed, based on the calculated HSV value of each RGB pixel in one of the video sources.

Stereo Mix

Two video sources are synchronized, and then output as alternating fields. This is used for creating active stereo outputs from separate left and right sources. The output is synchronized to one of the inputs. 120 Hz operation is possible, at up to 165 MPixel/sec.

Windowing

A window is defined within a background region, where the window may exhibit either the foreground or a mix of foreground and background.

Split Screen

A portion of the display (top or left) displays one image or a portion of an image, while the other portion (bottom or right) displays the other image, or portion of an image.

For simple windowing, inputs are mapped to the background channel as required for your application.

For complex video combining, such as RGB, luma, or chroma keying, inputs to be processed for keying are mapped to the foreground channel, and other video is mapped to the background channel.

As with all Westar video solutions, you have flexible area-of-interest control. You can select a specific area-of-interest in your input video, and map that area to any window size within an output foreground or background layer.

Spec Summary

   ¹ The Dual Link DVI video input (CH 6) cannot be re-sized or re-timed. If this
    input is used, the output timing will be locked to this input. If this input is not
    used, the EZwindowHR can be programmed to your desired output resolution.
