Kramer VS-41HD [6/23] Overview

Overview

3 Overview

The Kramer VS-41HD is a true 4x1 switcher

for standard definition

/ high

definition

• Input and output signals on BNC connectors and selector buttons

that automatically light up in different colors—red, when the

VS-41HD detects a ‘standard definition’ signal, or blue, when it

detects a ‘high definition’ signal

SDI signals that lets you distribute any one of the four inputs to

two identical outputs. The VS-41HD features:

• Reclocking and equalization on each input

• Distribution of digital information (embedded audio, Teletext, time code

and so on) during the vertical interval period

• The ability to switch genlocked video signals according to timing of the

GENLOCK reference input. Switching according to the Bi-level or

Tri-level Genlock input according to SMPTE RP-168

• Front panel locking, and an OFF button to disconnect the output

The VS-41HD is housed in a 19" 1U rack mountable enclosure and is fed

from a 100-240 VAC universal switching power supply. It can be controlled

via the front panel buttons, infrared remote control transmitter, remotely, by

RS-232 or RS-485 serial commands transmitted by a touch screen system, PC,

or other serial controller, as well as via the ETHERNET and/or remote contact

closure for forced operation.

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 that may

adversely influence signal quality and position your Kramer VS-41HD

away from moisture, excessive sunlight and dust

4 Your VS-41HD 4x1 HD/SD-SDI Switcher / DA

Figure 1, Table 1, and Table 2 define the VS-41HD 4x1 HD/SD-SDI Switcher / DA.

1 Switching is implemented during the vertical interval period according to the SMPTE RP-168 standard, when using

synchronized SDI sources

2 Standard Definition (SD) means an NTSC or PAL compatible video format, consisting of 480 (for NTSC) or 576 (for PAL)

lines of interlaced video

3 High Definition (HD) in this case includes 480p, 576p, 720p and 1080i (all @ 50/60Hz); 1080p @ 24/25Hz; as well as the

1/1.0001 refresh rates

4 The sources must be genlocked to the GENLOCK input in order to switch cleanly
