3 Overview
The Kramer VP-728 is a 9-input Proscale™ Presentation Switcher / Scaler
with unbalanced stereo and digital S/PDIF audio.
The VP-728 scales any composite, s-Video (Y/C), component video (YUV),
HDMI or computer graphics video signal, as well as jpeg files (via USB) up
or down to a selectable graphics or HDTV output resolution and provides
glitch-free switching between sources through FTB™ (fade-thru-black)
switching technology. The output signal is available simultaneously on a
15-pin HD computer graphics video (UXGA) connector and on an HDMI
connector.
The VP-728 features include:
•Silicon Optix HQV® Video Processing - HQV (Hollywood Quality Video)
processing 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
•Fade-Thru-Black (FTB™) Switching - the video fades to black and then the
new input fades from black for glitch-free and smooth switching. The output
signal provides constant sync so the display never glitches
•K-IIT XL™ Picture-in-Picture Image Insertion Technology - ultra stable
picture-in-picture, picture-and-picture, and split screen capability. 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
•Four user definable (universal) video inputs (each can be set as composite
video, s-Video (Y/C) or component video), two computer graphics video inputs,
two HDMI inputs and 1 USB input (for reading JPEG picture files1
•HDTV compatible component input
)
•HDTV output resolutions - 720p 1080i, and 1080p
•Scaled video outputs - HDMI and computer graphics video
•HDMI support of up to 2.25Gbps bandwidth per graphic channel2
•Multiple computer graphics output resolutions - including a user-defined output
resolution with selectable refresh rates
•Multiple aspect ratio selections
•Companion AFV (audio-follow-video) for every analog video input
•Embedded audio on the two HDMI inputs and output3
•Built-in noise reduction and picture enhancement features
1 JPEG files are recognized up to 2048x1536
2 Suitable for resolutions up to UXGA at 60Hz, and for all HD resolutions
3 The embedded audio feature is not available for the 1920x1200 and 1920x1080 resolutions

•Audio inputs - four (stereo audio or S/PDIF on two RCA connectors) for each
of the four universal video inputs; two stereo audio (on 3.5mm connectors) for
the two computer graphics video inputs; and embedded audio on the HDMI
inputs
•Audio outputs - S/PDIF and stereo audio (RCA connectors). Transcodes stereo
or S/PDIF audio to both stereo and S/PDIF audio and embeds audio onto the
HDMI output1
•Built-in Time Base Corrector - stabilizes video sources with unstable sync
•Built-in video Proc-Amp - color, hue, sharpness, contrast, and brightness are set
individually for each input
•A BLANK button, a FREEZE button, a RESET TO XGA/720P button (to
hardware-reset the output resolution); and a PANEL LOCK button2
•Built-in audio Proc-Amp - with bass, treble, balance and loudness control, as
well as audio delay
•Firmware upgrade3
•The slideshow option, letting you run a slideshow via the USB port
via the USB port
•An OSD (On-Screen Display) – for making adjustments – that can be located
anywhere on the screen4
In addition, the VP-728:
•Includes non-volatile memory that retains the last settings, after switching the
power off and then on again
•Digitally reprocesses the signal to correct mastering errors, and regenerates the
video at a higher line and pixel rate format, providing native-resolution video for
LCD, DLP and plasma displays
•Is specifically designed to improve video quality by reducing chroma noise
•Scales and zooms (to up to 400% of the original size)
•Can provide non-linear scaling for 4:3, 16:9 transformation
Control your VP-728 directly via the front panel push buttons, or:
•By RS-232 serial commands transmitted by a touch screen system, PC, or other
serial controller
•Remotely, from the infrared remote control transmitter (with on-screen menus)
1 Tip: if you want to use a 5.1 digital audio source, connect this HDMI or S/PDIF source (for example, a Blu-ray player)
directly to your receiver or display
2 The front panel blank, freeze and lock buttons can be programmed via the OSD menu (see Table 15)

3.1 About HDMI
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital1
In particular, HDMI
audio/video interface, widely supported in the entertainment and home cinema
industry. It delivers the maximum high-definition image and sound quality in use
today. Note that Kramer Electronics Limited is an HDMI Adopter and an HDCP
Licensee.

•Provides a simple
:
3interface between any audio/video source, such as a set-top
box, DVD player, or A/V receiver and video monitor, such as a digital flat LCD
/ plasma television (DTV), over a single lengthy4
•Supports standard, enhanced, high-definition video, and multi-channel digital

•Transmits all ATSC HDTV standards and supports 8-channel digital audio,
with bandwidth to spare to accommodate future enhancements and
requirements
on a single cable
•Benefits consumers by providing superior, uncompressed digital video quality
via a single cable6
•Is backward-compatible with DVI (Digital Visual Interface)
, and user-friendly connector
•Supports two-way communication between the video source (such as a DVD
player) and the digital television, enabling new functionality such as automatic
configuration and one-button play
•Has the capacity to support existing high-definition video formats (720p, 1080i,
and 1080p/60), standard definition formats such as NTSC or PAL, as well as
480p and 576p

3 With video and multi-channel audio combined into a single cable, the cost, complexity, and confusion of multiple cables
currently used in A/V systems is reduced
4 HDMI technology has been designed to use standard copper cable construction at up to 15m
5 HDMI supports multiple audio formats, from standard stereo to multi-channel surround-sound. HDMI has the capacity to
support Dolby 5.1 audio and high-resolution audio formats
6 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a
simple, cost-effective manner

3.2 Recommendations for Best Performance
To achieve the best performance:
•Connect only good quality connection cables, thus avoiding 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 and position your
Kramer VP-728 away from moisture, excessive sunlight and dust
