Chapter 1 Introduction
1.1 Overview
In the manual, HDC6831N HD-SDI Downconverter / Demultiplexer /Audio and Video Monitor is
introduced. The modules can be installed in 6800N series frame.
HDC6831N is a high definition downconverter from HD-SDI to SD-SDI or analog composite, in
addition, it also support SD-SDI to analog composite downconversion.
HDC6831N is a multiplexer with 2-pair AES/EBU digital audio outputs and 4-channel analog audio
outputs. The module characterizes 8-channel audio meter indication which can be overlapped on
CVBS output or SD-SDI output.
The module can display OSD menu, time code and standards of input and output, and can monitor
8-channel audio signal. Furthermore, it supports SNMP control and status indication.

1.2 Features
The HDC6831N offers the following features:
Auto-detect HD-SDI or SD-SDI input, and convert it into SD-SDI and CVBS outputs with the
approximate frequency
Support several standard conversion of 1080I，1080P，720P，1035I，576I，480I. For more
information, please refer to Tab. 1-2
2-channel reclocked HD/SD-SDI loop outputs
2-channel SD-SDI outputs after downconversion ( only for HD-SDI input), or 2-channel
SD-SDI outputs without downconversion ( only for SD-SDI input)

FCC Caution:
Any Changes or modifications not expressly approved by the party responsible for compliance could
void the user's authority to operate the equipment.
This device complies with part 15 of the FCC Rules.
Operation is subject to the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received, including interference that
may cause undesired operation.
Note: This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates uses
and can radiate radio 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.
