TERMINOLOGY

DDC

Short form for Display Data Channel. It is a VESA standard for communication between a monitor and a video adapter. Using DDC, a monitor can inform the video card about its properties, such as maximum resolution and color depth. The video card can then use this information to ensure that the user is presented with valid options for configuring the display.

DDWG

Digital Display Working Group DDWG are the creators of the DVI specification.

DVI

Digital Visual Interface. Connection standard developed by Intel for connecting computers to digital monitors such as flat panels and DLP projectors. A consumer electronics version, not necessarily compatible with the PC version, is used as a connection standard for HDTV tuners and displays. Transmits an uncompressed digital signal to the display. The latter version uses HDCP copy protection to prevent unauthorized copying.

HDCP

High-Bandwidth Digital Content Protection. Created by Intel, HDCP is used with HDTV signals over DVI and HDMI connections and on D-Theater D-VHS recordings to prevent unauthorized duplication of copy written material.

HDMI

The High-Definition Multi-media Interface (HDMI) is an industry-supported, uncompressed, all-digital audio/video interface. HDMI provides an interface between any compatible digital audio/video source, such as a set-top box, DVD player, and A/V receiver and a compatible digital audio and/or video monitor, such as a digital television (DTV).

HDTV

High-Definition Television. The high-resolution subset of our DTV system. The ATSC defines HDTV as a 16:9 image with twice the horizontal and vertical resolution of our existing system, accompanied by 5.1 channels of Dolby Digital audio. The CEA defines HDTV as an image with 720 progressive or 1080 interlaced active (top to bottom) scan lines. 1280:720p and 1920:1080i are typically accepted as high-definition scan rates.

RS-232

Recommended Standard 232. This is the de facto standard for communication through PC serial ports. It can refer to cables and ports that support the RS232 standard.

VESA

Video Electronic Standards Association, a consortium of manufacturers formed to establish and maintain industry wide standards for video cards and monitors. VESA was instrumental in the introduction of the Super VGA and Extended VGA video graphics standards with a refresh rate of 70 Hz, minimizing flicker and helping to reduce user eyestrain and fatigue.

Home Theater Scaler PLUS specifications

The Gefen Home Theater Scaler PLUS is a versatile device designed to enhance the viewing experience for home theater enthusiasts. It functions as both a video scaler and switcher, allowing users to connect multiple input sources to their display while improving video quality.

One of the standout features of the Gefen Home Theater Scaler PLUS is its ability to upscale video resolutions up to 1080p. This means that it can take lower-resolution feeds, such as 480i or 576p, and convert them to high-definition outputs, ensuring that all content looks crisp and clear on modern HDTVs. The scaler supports a variety of input formats, including HDMI, Component, Composite, and S-Video, making it suitable for a wide range of devices, from gaming consoles and Blu-ray players to older VHS systems.

Another key technology in the Gefen Home Theater Scaler PLUS is its advanced de-interlacing capability. This technology helps smooth out video playback and reduce artifacts that may occur when handling interlaced video signals. The scaler also features a comprehensive set of video adjustments, including brightness, contrast, saturation, hue, and sharpness, giving users the ability to fine-tune their viewing experience based on specific preferences and room lighting conditions.

The device operates with an embedded scaling engine that supports various output formats, including native resolutions for most modern TVs. It intelligently selects the best scaling process for each input, ensuring optimal image quality regardless of the source material. Additionally, the Gefen Home Theater Scaler PLUS is equipped with an easy-to-use on-screen menu, allowing users to navigate its settings effortlessly.

Another noteworthy characteristic is the built-in audio extraction feature. This allows users to separate audio from the video signal, sending it to an external audio system or receiver. This is particularly useful for those who want to enjoy immersive surround sound while integrating multiple multimedia sources into their home theater setup.

With its convenient form factor and comprehensive features, the Gefen Home Theater Scaler PLUS is a valuable addition for anyone seeking to upgrade their home entertainment experience. It bridges the gap between older and newer technologies, ensuring compatibility while maximizing video quality across all devices.
