1 Introduction Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront video, audio, presentation, and broadcasting professionals on a daily basis.
2 Getting Started We recommend that you: Unpack the equipment carefully and save the original box and packaging materials for possible future shipment i 2.1 Review the contents of this user manual Go to http://www.kramerelectronics.com/support/product_downloads.asp to check for up-to-date user manuals, application programs, and to check if firmware upgrades are available (where appropriate).
2.3 Recycling Kramer Products The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC aims to reduce the amount of WEEE sent for disposal to landfill or incineration by requiring it to be collected and recycled. To comply with the WEEE Directive, Kramer Electronics has made arrangements with the European Advanced Recycling Network (EARN) and will cover any costs of treatment, recycling and recovery of waste Kramer Electronics branded equipment on arrival at the EARN facility.
3 Overview The Kramer VP-461 is a high quality Video Scaler. It accepts one of three inputs: a computer graphics signal on a 15-pin HD connector, an HDMI and a DisplayPort signal. It scales the video, embeds the audio and outputs the signal to the HDMI output, as well as to the PC output together with an unbalanced audio output. The VP-461 Video Scaler features: K-Storm™ Scaling Technology - Kramer’s extremely high performance scaling technology.
HDCP Compliant - The HDCP (High Definition Content Protection) license agreement allows copy-protected data on the HDMI input to pass only to the HDMI output In addition, the VP-461 Video Scaler: Includes luma keying via the PiP window Features advanced EDID management (native resolution and color depth) per input Analyzes the connected output’s EDID for optimal scaling Supports picture zooming both on main and PiP window from 100% to 1600%, including separate V and H sharpness control
3.1 HDCP Compliance i If the HDMI signal is HDCP protected, it can only appear on the HDMI output if it is connected to an HDCP compliant display. The VP-461 will not output a picture on an HDMI display that is not HDCP compliant, nor will a picture be shown on the PC output; instead it will show a black screen. In the dual window display mode (see Section 6.2), even if only one of the inputs is HDCP protected, and is output to a non compliant display, it will affect the entire screen and turn it black.

5.8.1 The Luma Keying Feature The luma keying feature is an easy-to-use method of compositing two video sources into a single image. By setting up a “key” image or clip on a black background, it can be merged – or overlaid – onto the primary video. The key image is transparent in the areas of its dark background, resulting in a picture which looks as if the key image is cut out and pasted over the primary image.
6 The Display Modes The VP-461 can function in the single window display mode (the factory default setup) or the dual window display mode. 6.1 The Single Window Display Mode The single window mode shows one window on the screen. The window size can be customized, and its parameters modified via the OSD menu. 6.1.
The dual window mode appears in the following preset PiP configurations: Picture-in-Picture, with a smaller PiP window superimposed over a full main window image Picture + Picture, where both images appear side-by-side and the aspect ratios of both images are maintained Split, where both images are placed side-by-side with the same height The window customization feature (see Section 5.2) lets you customize the dual window mode layout (main window and PiP window) to any size.
6.2.1 Activating the Dual window Mode You can activate the dual window mode (indicated by an illuminated PIP front panel button) in any of the following ways: Press and hold (for 3 seconds) the front panel PIP button The latest PiP configuration appears Press the PIP button on the IR remote control transmitter (see Section 7.
