INTRODUCTION
1.1.
General Introduction
VP-791 is a very flexible image scaler developed specifically for driving large screen displays from SD-
SDI, HD-SDI and 3G-SDI serial digital source.
VP-791 features a state of the art digital image processor which provides market leading HD& SD per-
pixel multiple Iow-angle motion-adaptive de-interlacing and automatic film pull-down correction for 3:2
and 2:2, significantly outperforming the capabilities of benchmark competitor products.
VP-791 features excellent image processing algorithms for the very best scaling, film and video noise
reduction and MPEG artefact reduction.
VP-791 uses a high performance SDI de-serializer with cable equalization.
The output format can be set to I/O Lock mode where it locks the output frame rate to the input frame
rate dynamically without frame rate conversion so as to reduce system latency, or it can be set to a fixed
output frame rate for driving basic screens which are not 50Hz-compatible. Furthermore, the VP-791
can be set to have the output resolution match the input resolution to preserve aspect ratio. A Low
latency mode with non-motion adaptive reduced processing is available to further reduce latency.
Outputs are available in DVI digital formats.
VP-791 supports Pan, Zoom and Tilt to select a part of the input image, fill the screen and pan within it.
VP-791 features embedded warp functions to adjust the image in a projection scenario to match a
rotated, tilted or curved screen. For 9:16 portrait mode signage special predefined warp maps are
available to rotate and stretch a video image to fill a +/-90° rotated display panel.
System control is via an OSD controlled by keys on the front panel or through an intuitive ‘Windows’
application connected via a normal RS232 serial port or via TCP/IP (ethernet).
