EDID Minder and Key Minder

To enhance and simplify integration of sources and displays, the DSC 301 HD features two exclusive Extron technologies: EDID Minder and Key Minder^®. EDID Minder manages EDID communication between the display device and input sources. For HDMI signals with protected content, Key Minder authenticates and maintains continuous HDCP encryption between input sources and displays to ensure quick and reliable switching.

When receiving an HDCP-encrypted HDMI input source signal, the DSC 301 HD outputs a full-screen green signal on any video output connected to a non-HDCP compliant display. This provides immediate visual confirmation that the protected content cannot be viewed on this display. In addition, the DSC 301 HD provides real-time verification of the HDCP status for the HDMI input and output, offering valuable feedback to system operators and helpdesk support staff.

High Performance Video Processing

The DSC 301 HD features advanced video processing with the ability to scale HDMI, HDTV, RGB, and standard definition video signals to a common high resolution output. It accepts and outputs signals up to 1920x1200, including 1080p/60 and 2K. The DSC 301 HD also provides high performance deinterlacing of all interlaced signals up to 1080i, and Deep Color processing to deliver optimal image quality. In addition, the color space and chroma subsampling of the HDMI output can be automatically set to ensure compatibility with a connected DVI or HDMI display.

The DSC 301 HD features automatic 3:2 and 2:2 pulldown detection, which maximizes image quality for content sources originating from film. The DSC 301 HD also uses a digital 3D adaptive comb filter that optimizes decoding of NTSC, PAL, and SECAM sources for integration into systems worldwide.

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.

Enhanced Audio Capabilities

The DSC 301 HD features HDMI audio embedding and flexible audio switching to accompany incoming video sources. Any input audio signal can be embedded onto the HDMI output for simplified system connections. In addition, the DSC 301 HD provides gain and attenuation adjustments for each analog input.

Multiple Options for Control and Operation

The DSC 301 HD features front panel controls for quick access to functions. Remote configuration and control are available via RS-232 and USB, plus easy-to-use on-screen menus. The on-screen menus provide full control over the unit's functions and settings, including quick access to key parameters such as input and output video formats and resolutions. The DSC 301 HD is housed in a 1" (2.5 cm) high, half rack width metal enclosure and can easily be integrated into a variety of environments.

Features

HDMI and analog video scaling to HDMI — Digital and analog video sources can all be scaled to high resolution HDMI output.

Inputs: One HDMI, one RGBHV or component video on 15-pin HD, one composite video on BNC, three 3.5 mm stereo mini jacks for audio

Output: One HDMI

Auto-switching between inputs — Auto-switching allows for simple, unmanaged installation in locations such as in a lectern or under a conference table. When multiple inputs are active, the switching priority is configurable.

HDMI audio embedding — Analog input audio signals can be embedded onto the HDMI output signal.

Selectable output rates from 640x480 to 1920x1200, including 1080p/60 and 2K — Available output rates include computer and video up to 1920x1200, including 1080p/60 and 2K.

Advanced scaling engine with 30‑bit precision processing and motion-adaptive deinterlacing for signals up to 1080i — Image scaling and video format conversion are performed at 30‑bit precision for enhanced color accuracy and picture detail. Advanced deinterlacing for all interlaced signals up to 1080i delivers optimized image quality.

HDCP compliant — Ensures display of content-protected media and interoperability with other HDCP-compliant devices.

User-selectable HDCP authorization — Allows the unit to appear HDCP compliant or non-HDCP compliant to the connected source, which is beneficial if the source automatically encrypts all content when connected to an HDCP-compliant device. Protected material is not passed in non-HDCP mode.

Supported HDMI specification features include data rates up to 6.75 Gbps, Deep Color, and HD lossless audio formats

Key Minder^® continuously verifies HDCP compliance for quick, reliable switching — Key Minder authenticates and maintains continuous HDCP encryption between input and output devices to ensure quick and reliable switching in professional AV environments.

EDID Minder^® automatically manages EDID communication between connected devices — EDID Minder ensures that all sources power up properly and reliably output content for display.

Aspect ratio control — The aspect ratio of the video output can be controlled by selecting a FILL mode, which provides a full screen output, or a FOLLOW mode, which preserves the original aspect ratio of the input signal.

HDCP authentication and signal presence confirmation — Provides real‑time verification of HDCP status for each digital video input and output. This allows for simple, quick, and easy signal and HDCP verification through front panel LEDs, RS‑232, or USB, providing valuable feedback to a system operator or helpdesk support staff.

HDCP Visual Confirmation — When HDCP‑encrypted content is transmitted to a non‑HDCP compliant display, a full‑screen green signal is sent to the display for immediate visual confirmation that protected content cannot be viewed on that display.

HDMI to DVI Interface Format Correction — Automatically enables or disables embedded audio and InfoFrames, and sets the correct color space for proper connection to HDMI and DVI displays.

Selectable seamless switching transitions — Seamless cut through black, and fade through black transition effects are available at the scaled video outputs.

AFL™ - Accu-RATE Frame Lock — A patented technology exclusive to Extron that locks the output frame rate to a designated input to eliminate stuttering caused by frame rate conversion.

Image freeze control — A live image can be frozen using RS-232 serial control or USB.

Auto-Image setup — When activated, the unit automatically optimizes the image by analyzing and adjusting to the video input signal. This can save time and effort in setting up a newly connected source, particularly in presentation environments where different guest presenter laptops with various output resolutions will be connected.

Auto Input Memory — When activated, the unit automatically stores size, position, and picture settings based on the incoming signal. When the same signal is detected again, these image settings are automatically recalled from memory.

On-screen menus — Intuitive on-screen menus allow for easy system setup using the front panel controls. Key parameters such as input and output video formats and resolutions are conveniently grouped on the initial Quick Setup screen, while additional screens provide full control over the unit's other functions and settings.

Output Standby Mode — The unit can be set to automatically mute video and sync output to the display device when no active input signal is detected. This allows the projector or flat-panel display to automatically enter into standby mode to save energy and enhance lamp or panel life.
