VP-774 - 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

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).

2.1 Achieving the Best Performance

To achieve the best performance:

Use only good quality connection cables (we recommend Kramer high-

performance, high-resolution cables) to avoid interference, deterioration in

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

associated with low quality cables)

Do not secure the cables in tight bundles or roll the slack into tight coils

Avoid interference from neighboring electrical appliances that may adversely

influence signal quality

Position your Kramer VP-774 away from moisture, excessive sunlight and dust

This equipment is to be used only inside a building. It may only be

connected to other equipment that is installed inside a building.

2.2 Safety Instructions

Caution:

There are no operator serviceable parts inside the unit

Warning:

Use only the power cord that is supplied with the unit

Warning:

Do not open the unit. High voltages can cause

electrical shock! Servicing by qualified personnel only

Warning:

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. For details of Kramer’s recycling arrangements in your particular country go

VP-774 - Overview

3 Overview

The Kramer VP-774 is a high quality presentation switcher and scaler. It accepts

one of nine inputs: an SDI signal on a BNC connector, a DisplayPort (DP) signal on

a DisplayPort connector, one composite video signal on an RCA connector, two

computer graphics signals on 15-pin HD connectors, and four HDMI signals on

HDMI connectors. It scales the video, embeds the audio, and simultaneously outputs

the signal as follows: to two HDMI outputs, to an SDI output and to an HDBaseT TP

output, together with a digital audio output and a balanced stereo audio output.

The VP-774 Presentation Switcher / Scaler features:

PixPerfect™Scaling Technology –Kramer’s precision pixel mapping and

high quality scaling technology. High-quality 3:2 and 2:2 pull down de-

interlacing and full up and down scaling of all video input signals

State-of-the-art video processing technology, with the highest quality de-

interlacing, noise reduction, and scaling performance for both standard-

definition and high-definition signals

K-IIT XL™ Picture-in-Picture Image Insertion Technology - Ultra stable

picture−in−picture, picture−and−picture and split screen capability, or fully

customizable windows’size and position control: any source can be inserted

into or positioned next to any other source and resized as desired

Ultra Fast Fade-Thru-Black (FTB™) Switching - Video switching transitions

are clean and ultra-fast. The video fades to black and the new input fades

from black for smooth, glitch-free switching. The output signal provides

constant sync so the display never glitches

An emergency alert system that can have a national or campus-wide

notification immediately displayed when an emergency situation develops, by

means of automatic text overlaying, either via a crawler or a full screen cover

up, as well as an optional audio alert

Port tunneling, bidirectional RS-232 interface –simple control commands

and data can flow in both directions from a controller to the VP-774 via the

Ethernet, allowing status requests and control of the destination unit

Advanced deinterlacing functions - including 3D comb filtering, film mode,

diagonal correction and motion detection

VP-774 – Overview

Scaled Outputs –2 HDMI outputs, an SDI output and an HDBaseT TP

output simultaneously

HDBaseT™ technology with a bandwidth of up to 6.75Gbps (2.25Gbps per

graphic channel)

Up to 130m (430ft) normal mode; up to 180m (590ft) Ultra mode (1080p

@60Hz @24bpp) when using BC-DGKat623 cables

For optimum range and performance, use Kramer's BC−DGKat524,

BC−DGKat623 and BC−DGKat7a23 shielded twisted pair (STP) cables.

Note that the transmission range depends on the signal resolution,

graphics card and display used. The distance using non−Kramer CAT 5,

CAT 6, and CAT 7 cables may not reach these ranges.

Output Resolutions –HDTV and Computer Graphics up to 2K and

1080p/UXGA with selectable refresh rates

Multiple Aspect Ratio Selections –Follow input, follow output, best fit,

letterbox

Multi-Standard SDI support - SDI (SMPTE 259M), HD-SDI (SMPTE 292M)

and 3G HD-SDI (SMPTE 424M)

Looping 3G HD-SDI Input

SDI channeling, letting you select one active audio signal and three

bypassed signals from eight embedded stereo audio channels

Multi-Standard Video support - NTSC (3.58/4.43), PAL (M/N/60) and SECAM

Built-in Time Base Corrector - Stabilizes unstable video sources

Built-in Proc-Amp with enhanced functions such as color correction, gamma

and dither

Input and output audio level adjustment

Balanced stereo audio inputs, with two microphone inputs as well as digital

stereo and balanced stereo outputs

Selectable Microphone talkover or mix modes

Automatic detection and selection of the HDMI and DP embedded audio.

The VP-774 automatically outputs the signal from the HDMI and DP

embedded audio inputs or performs an analog takeover to output the

respective analog audio input
