The Extron DSC HD‑HD 4K PLUS A and DSC HD‑HD 4K PLUS A xi are high-performance scalers capable of converting between HDMI resolutions up to 4096x2160 at 60 Hz. These HDCP 2.3‑compliant scalers feature HDMI 2.0 connections that support data rates up to 18 Gbps. They incorporate the Extron-exclusive Vector 4K™ scaling engine, specifically designed for critical-quality 4K applications including full-motion video and highly detailed computer graphics. Both models support single path 4K signals at 60 Hz with 4:4:4 processing. The DSC HD‑HD 4K PLUS A xi also supports dual path 4K/60 signals at 4:4:4 using two connections. Integrator-friendly features include on‑screen display, stereo audio embedding and de‑embedding, internal test patterns, and the ability to display custom images and logos for on‑screen messages and corporate branding.

Versatile 4K Signal Integration

The DSC HD‑HD 4K PLUS A scaler can process single-path 4K signals. For applications requiring more advanced 4K signal management, the DSC HD‑HD 4K PLUS A xi features a pair of HDMI inputs and outputs. The additional input and output allow integration with PC graphics cards and large-venue projectors that support 4K as two columns. For digital signage applications, a pair of 1080p inputs can be displayed side-by-side on a single 4K output. Alternatively, the DSC HD‑HD 4K PLUS A xi can deliver two simultaneous scaled outputs up to 4096x2160 at 60 Hz for feeding two downstream displays without the need for a distribution amplifier.

Vector 4K Scaling

Both scalers incorporate the Extron-exclusive Vector 4K scaling engine, developed in‑house and engineered to deliver best-in-class image upscaling and downscaling. The Vector 4K engine embodies several Extron-patented scaling technologies, plus a new set of image processing algorithms that deliver uncompromising scaling performance. This enables sharp, accurate scaling of standard definition and high definition signals up to 4K, as well as downscaling of 4K source signals for lower resolution displays without losing critical image detail.

High Performance Video Processing

The DSC HD‑HD 4K PLUS A scalers provide high performance deinterlacing of all interlaced signals up to 1080i, and Deep Color processing to deliver optimal image quality. Automatic 3:2 and 2:2 pulldown detection maximizes image quality for content sources originating from film. Additionally, the color space and chroma sampling of the HDMI output can be automatically set to ensure compatibility with a connected DVI or HDMI display.

Selectable FILL and FOLLOW modes are also available to ensure the proper aspect ratio of the output. FILL mode provides full screen output, while FOLLOW mode preserves the original aspect ratio of the input signal.

Display Custom Images and Logos

These scalers provide the convenience of uploading custom images, which can be displayed as a screen saver after a predefined duration of inactivity at the video input, or whenever the input is disconnected between presentations. A customized image can also be displayed whenever HDCP‑encrypted content is transmitted to a non‑HDCP compliant display.

A custom graphic logo, such as a company logo, can be inserted into any presentation. Several key effects are available, and a logo can be positioned anywhere on‑screen.

Enhanced Audio Capabilities

DSC HD‑HD 4K Series A scalers include a convenient two‑channel analog audio input for embedding audio onto the HDMI output, as well as a two‑channel analog audio output for sending de‑embedded audio to a sound system or other audio destination. They also deliver essential audio integration capabilities, including discrete, selectable analog and digital audio muting, input gain and attenuation, and output volume control.

Multiple Options for Control and Operation

DSC HD‑HD 4K PLUS A scalers feature front panel controls for quick access to functions. Remote configuration is available via USB and Ethernet, while external control is available through RS‑232 and Ethernet. The on‑screen menus provide control over the unit's functions and settings, including quick access to key parameters such as input and output video formats and resolutions. Additionally, LED indicators on the front panel provide visual confirmation of video input and output signals, audio input and output signals, and the presence of HDCP encryption. They are housed in 1U, half rack width metal enclosures and can be easily integrated into a variety of environments.
