Product Overview

Chapter 1 Product Overview

This article is mainly about ACOHD6800 module, which is a 1RU card that can
be installed in 6800N series frame.
ACOHD6800 4×1 module is an emergency switcher, it offers supervision for
the real-time state of input signal, detection and alarm for video loss, EDH,
freeze frame and black burst. It can manually or automatically switch from the
primary input to the backup input once detecting abnormal signals or alarms,
thus it will keep consistency for the output. It is widely used in studio,
transmission control rooms, TV Stations and so on.
ACOHD6800 4×1 module offers four SD/HD-SDI input signals, one video loop
output with clock recovery, and the primary input IN1 offers a bypass relay
protection for the output. It supports the clean switching technology which is
realize by the internal circuitry, this technology provides continuous video
streams, and ensures a smooth switching without video flashing and audio
noise.
Switch control can be performed automatically or manually via GPI or a
matched remote control panel. In manual mode, switch control can be
undertaken via a remote control panel, or simply via GPI. In automatic mode,
the card will perform switch control based on internal signal analysis with alarm
conditions, and the status of the inputs. You can get the switched results by the
status of the connected remote control panel or the web page on the
connected computer. In automatic mode, you can set the automatic switching
mode, selecting from downward or upward. The IN1 is a particular bypass
channel to ensure continues output in case of a power failure.

ACOHD6800 modules support the following features:

Features

 Provides switching among three input HD/SD-SDI signals, and

provides one reference input signal, one HD/SD-SDI output

 Support selecting control mode between manual control and automatic

control

 The automatic mode performs based on signal analysis of video loss,

EDH, freeze frame, black burst and audio supervision.

 Build-in automatic horizontal corrector, and adjustable delay

 Detecting the trigger of alarm criteria for the control mode switch-over

 Support controls through remote control panel, GPIO and RS422

 Input IN1 bypass to the output in the event of power failure or module

missing

 The input cable equalization automatically

 Support clean switching technology

 Configures the modules through switches or network control panel

Functionality

 Alarms when video lost, static frame or detecting black field

 Supports power off memory, the settings will be restored if the module

loses power

 Provides frame synchronizer

 Supports intelligent protection function in order to avoiding "misuse".

When the input signal is detected abnormal, the switching operation for
output would be invalid.

frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more of
the following measures:

Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
