Our 1,000-plus different models now appear in 11 groups that are clearly defined

by function: GROUP 1: Distribution Amplifiers; GROUP 2: Switchers and Matrix

Switchers; GROUP 3: Control Systems; GROUP 4: Format/Standards Converters;

GROUP 5: Range Extenders and Repeaters; GROUP 6: Specialty AV Products;

GROUP 7: Scan Converters and Scalers; GROUP 8: Cables and Connectors;

GROUP 9: Room Connectivity; GROUP 10: Accessories and Rack Adapters and

GROUP 11: Sierra Products.

Congratulations on purchasing your Kramer VP-747 Universal Presentation Matrix

Switcher / Scaler. The VP-747 is a true multi-standard video to graphics scaler and

seamless switcher with eight universal inputs comprised of five BNC connectors

each of which can accommodate a composite video, s-Video (Y/C), component

video (RGB/YUV), RGBS, or RGBHV signal. Input 1 and input 2 also accommodate

DVI/HDMI inputs. (The HDMI connector connects to a DVD source via the Kramer

ADC DM/HF adapter). It has dual scalers, one for the preview and the other for the

program output. Dual scalers are required to do "live" seamless transitions from one

source to another. It is ideal for these typical applications:

•Presentation applications that require a preview option

•Projection systems in conference rooms, board rooms, auditoriums, hotels,

and churches

•Presentations requiring seamless switching between inputs, using special

effects, cuts and fades

2 VP-747 - Getting Started

2 Getting Started

We recommend that you:

•Unpack the equipment carefully and save the original box and packaging

materials for possible future shipment

•Review the contents of this user manual

•Use Kramer high performance high resolution cables

•Use only the power cord that is supplied with this machine

Go to http://www.kramerelectronics.com to check for up-to-date

user manuals, application programs, and to check if firmware

upgrades are available (where appropriate).

2.1 Achieving the Best Performance

To achieve the best performance:

•Use only good quality connection cables to avoid interference, deterioration

in signal quality due to poor matching, and elevated noise levels (often

associated with low quality cables)

•Avoid interference from neighboring electrical appliances that may adversely

influence signal quality

•Position your Kramer VP-747 away from moisture, excessive sunlight and

dust

VP-747 - Overview 3

3 Overview

The VP-747 Universal Presentation Matrix Switcher/Scaler is a true multi-standard

video to graphics scaler and presentation switcher for a wide variety of

presentation and multimedia applications. It consists of a very high quality scaler

with many user-selectable graphics or HDTV output resolutions, as well as a user-

definable output mode (recommended for advanced users only – non-standard

settings may not be recognized by the display device).

The VP-727A Audio Switcher and VP-727A-BA Balanced Audio Switcher are

audio companion switchers for the VP-747, and either can operate in conjunction

with it and the VP-747T Presentation Switcher Control Panel and also with the

VP-727T.

In particular, the VP-747 features:

•Silicon Optix HQV® Video Processing (Hollywood Quality Video) which

represents the state-of-the-art in video processing technology, with the

highest quality de-interlacing, noise reduction, and scaling performance for

both standard-definition and high-definition signals

•Eight sets of universal INPUT BNC connectors: R/PR, G/Y/CV, B/PB/C,

HS/CS, and VS.Each set can be programmed to operate as: composite

video, s-Video, component video, RGsB/YUV, RGBS, or RGBHV

Sometimes called YUV, or Y, B-Y, R-Y, or Y, Pb, Pr. The component input type (HDTV

or YCbCr) may be set as HD or SD.

•Two DVI/HDMI inputs (the HDMI connector connects to a DVD source via the

Kramer ADC DM/HF adapter) (for input 1 and input 2) that support up to

1.65Gbps bandwidth per graphic channel (suitable for resolutions up to

UXGA at 60Hz, and for all HD resolutions)

•HDTV compatibility and HDCP compliance

The HDCP (High Definition Content Protection) license agreement allows copy-

protected data on the HDMI input to pass to the HDMI output only.

•Scaling of selected sources to DVI/HDMI, RGBHV (Y, Pb, Pr) and VGA

outputs simultaneously

4 VP-747 - Overview

•Dual scalers—for “live” seamless transitions from one source to another—

with two independent outputs: a PREVIEW OUT and a PROGRAM OUT

(see Section 7.2

The PREVIEW output—including an OSD menu for making adjustments—is for

determining how the scaled output looks before displaying live during a presentation, as

well as for setting the special effects that harmonize the transition when changing

between sources.

Both outputs have separate sets of connectors for DVI/HDMI, VGA (a 15-pin HD

computer graphics video connector), and RGBHV/YPbPr (on BNC connectors)

•Eight PREVIEW input buttons for switching a selected input to the PREVIEW

output and eight PROGRAM input buttons for switching a selected input to

the PROGRAM output

•Two transition modes (accessible via the OSD): the Swap mode and the

Follow mode. When pressing the TAKE button in the Swap mode, the

preview and program inputs switch positions; when pressing in the Follow

mode, the program input follows the preview input

•Scaling and zooming (to up to 400% of the original size)

•High quality de-interlacing 3:2/2:2 pull down

•The frame-rate of a converted movie (24 frames per second) to video

frequencies (25 frames per second (PAL); 30 frames per second (NTSC)

•K-IIT XL™ Picture-in-Picture Image Insertion Technology with ultra stable

picture-in-picture, picture-and-picture, and split screen capability for both the

PREVIEW and the PROGRAM outputs. Any video source can be inserted

into or positioned next to a computer graphics video source or vice versa

with window positioning and sizing controls

•Saving of all settings in non-volatile memory in the unit

•Support for firmware upgrade via USB

•A sophisticated front panel lockout (see Section 7.5

•A Take button for executing preview to program switching (with transition

effects, which include cuts, fades, and wipes The direction of the wipe may

be selected by the user. The speed of each transition can be adjusted)

)

•ProcAmp controls for both outputs (processing amplification enables

adjustment of different video and audio signal parameters)

•Multi-standard video support: PAL, SECAM, and NTSC (3.58/4.43)

VP-747 - Overview 5

•A built-in Time Base Corrector (TBC) that stabilizes video sources with

unstable sync

•Multiple color space, outputting RGB or YUV

•Support for embedded audio on the HDMI inputs and outputs

The embedded audio feature is not available for the RGB resolutions 1920x1200 and

1920x1080. (It is

•Digital reprocessing of the signal to correct mastering errors, and

regenerates the video at a chosen line and pixel rate format, providing, for

example, native-resolution video for LCD, DLP and Plasma displays

available for 1080p)

•Scaling of graphics resolutions to other resolutions

•A unique graphics-scaling engine with image enhancement algorithms, which

are built into the firmware

•A special design to improve video quality by reducing chroma and temporal

noise

•Reduced digital artifacts such as mosquito and block noise

•T-bar emulation via RS-232

•A rugged, professional 19" 3U rack-mountable metal enclosure

•A universal 100-240V AC automatic power supply, and rear panel power

switch

Control the VP-747 via the:

•Front panel and a user-friendly menu-driven OSD (see Section 8.1

•High contrast LCD Display (see

)

Section 8.2

•IR remote control transmitter (see

)

Section 8.3

•Ethernet/RS-232 (see

)

Section 8.4

•Kramer VP-747T Presentation Switcher Control Panel
