1 Introduction
This manual explains how to operate your PS200, PS200T, PS300T Scaler-Switcher.
1.1 System Overview
The PS/LS200, PS/LS200T, PS/LS300T Series of scalers-switchers feature excellent image processing
algorithms for the very best in scaling, motion-adaptive de-interlacing and automatic film 3:2 and 2:2
pull-down correction. The new generation of products significantly outperforms the capabilities of
benchmark competitor products.
In addition to full 4K processing, new and unique technology allows for seamless switching between
different inputs as fast as ¼ of a second.
The PS/LS200, PS/LS200T, PS/LS300T Series feature with a flexible, high performance video input front
end that allows them to accept and process a wide variety of inputs. HDMI, DVI and Display Port video
with HDCP encryption is supported, as are computer graphics inputs in SVGA analogue and HDMI/DVI
digital formats. Analogue support also includes true component video in YPbPr and RGBS formats as
well as composite (CVBS) inputs.
A high-performance video decoder is utilised with 4x oversampling and 3D Y/C separation for
outstanding video image clarity. The output frame rate can lock to the input frame rate dynamically
without frame rate conversion in order to reduce system latency; or it can be set to a fixed output
frame rate, e.g. for driving basic screens which are not 50Hz-compatible. The output format can also
lock to an externally provided synchronization signal on various models (see model matrix).
3GSDI/HDSDI/SDI digital formats are supported on various models (see model matrix below).
Outputs are available in HDMI/DVI digital formats as well as 3GSDI and HDBaseT (see model matrix
below). All outputs are active simultaneously, except in the cases where the formats are not
compatible. For example, for the PC graphic formats that are not supported by the SDI standards, the
3GSDI output will be disabled. Also note that if an HDCP encrypted signal is connected to the DP,
HDMI or DVI input, the HDMI and DVI output signals will be similarly HDCP encrypted and the 3GSDI
output will be disabled. HDCP capability can be switched off per input, so that a source can transmit
non-protected content material.
The Pan, Tilt and Zoom (PTZ) feature allows users to select a ‘region of interest’, ROI, of the input image
to fill the screen and pan and tilt within it.
The Video Wall feature allows multiple units to work synchronously and be part of a large matrix
configuration, up-to 4x4. Each unit automatically crops a section of the input video image and displays
it on the corresponding projector or screen.
LEDView models offer an additional menu allowing users to easily and quickly define the area within
the output raster where the scaled image will be placed. This area is defined to match exactly the size
of the LED wall. The image can be reduced to an area as small as 128x96 pixels.
In system configurations where, multiple units are driving large LED walls, a unique splicing menu
allows users to select the portion of the input image that each unit will process. Although the input
