Video Processors and Scalers

The Aurora DIDO-X4 represents an advanced example of modern video processing capability, functioning as a 4x4 scaler matrix processor with features including contrast edge blending for projector alignment. Also features image rotation for portrait-mode video walls, chroma keying for source overlay effects, and built-in USB 3.1 capture for software video conferencing integration. The modular input card architecture accommodates different source types to match installation requirements.

Key Digital's KD-VW4x4ProK addresses video wall applications with a 4K UHD 4-input, 4-output video wall processor supporting multiple layout modes, seamless matrix switching, plus both HDMI and UHDoTP (HDBaseT) outputs. The included receiver units enable distribution of processed video to remote displays over category cable.

Video processor capabilities span multiple functional categories. Scalers convert input resolutions to match display native resolutions, optimizing image quality and eliminating compatibility issues. Matrix routing enables any input to be directed to any output or multiple outputs simultaneously. Window processors allow multiple sources to be displayed in adjustable windows on a single output. Edge blending processors align and overlap multiple projector images for seamless wide-format displays.

These processors find application in executive boardrooms, command and control centers, broadcast facilities, digital signage networks, and house of worship environments. Integration capabilities typically include RS-232 and IP-based control for room automation systems, web-based configuration interfaces, and support for professional video formats and frame rates.

Video processors range from compact units handling basic scaling needs to enterprise-class systems managing complex video wall installations.

Frequently Asked Questions

Q1. What is the difference between a video scaler and a video processor?

A. A scaler performs the specific function of converting input video resolution to a different output resolution. A video processor is a broader term encompassing scalers plus additional capabilities like matrix switching, window manipulation, edge blending, color correction, and format conversion. Most modern video processors include scaling functionality among their features.

Q2. Can video processors capture content for video conferencing systems?

A. Some advanced video processors like the Aurora DIDO-X4 include USB capture outputs that present the processed video as a camera source to computers, enabling integration with software video conferencing platforms like Zoom and Teams. This allows conference participants to view switched or processed content.

3. What is edge blending and when is it needed?

A. Edge blending is a technique used when multiple projectors create a seamless wide image by overlapping their projection areas. Video processors with edge blending capability adjust the brightness and geometry of overlapping regions to create invisible transitions between projector images, essential for immersive presentations and video walls.

Q4. How do video processors integrate with room control systems?

A. Video processors typically support RS-232 serial control, IP-based control via TCP/IP, and sometimes IR remote control. These interfaces enable integration with room automation systems from Crestron, Extron, AMX, and others, allowing preset recall, input selection, and output routing through centralized control interfaces.
