FEDERAL COMMUNICATIONS COMMISSION AND INDUSTRY
CANADA RADIO FREQUENCY INTERFERENCE STATEMENTS
This equipment generates, uses, and can radiate radio-frequency energy, and if
not installed and used properly, that is, in strict accordance with the manufac-
turer’s instructions, may cause interference to radio communication.
It has been tested and found to comply with the limits for a Class A computing
device in accordance with the specifications in Subpart B of Part 15 of FCC
rules, which are designed to provide reasonable protection against such
interference when the equipment is operated in a commercial environment.
Operation of this equipment in a residential area is likely to cause interference,
in which case the user at his own expense will be required to take whatever
measures may be necessary to correct the interference.
Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
This digital apparatus does not exceed the Class A limits for radio noise emis-
sion from digital apparatus set out in the Radio Interference Regulation
of Industry Canada.
Le présent appareil numérique n’émet pas de bruits radioélectriques

Chapter 2: Overview
2. Overview
2.1 Introduction
VS-2000-ENC is a live streaming media encoder that interfaces with HDMI sig-
nals for delivering media over IP networks. VS-2000-ENC can be used with a
third-party decoder such as a set-top box, VLC or Kodi media player on PCs to
provide complete end-to-end streaming systems. It features one HDMI input
and one Ethernet output for simplified integration into AV systems.
VS-2000-ENC employs standards-based H.264/MPEG-4 AVC encoding and
MPEG-2 transport streams, and outputs IP streams that can easily be decoded
and viewed on the third-party decoders. The multicast streams are output and
can be received and decoded by multiple decoders. Up to ten RTSP sessions can
work simultaneously. Encoding controls provide adjustments for bit rate and
quality. VS-2000-ENC offers integration-friendly control features for LAN (Web
GUI and Telnet) providing simple, flexible, control and management options.
By extending AV signals over networks, VS-2000-ENC significantly expands AV
system capability.
2.2 Features
• Uses standards-based H.264/MPEG-4 AVC video compression.
• Supports HDMI input signals up to 1920 x 1200@60Hz, including Full
HD1080P@60Hz — VS-2000-ENC supports a wide range of input resolutions,
from standard definition up to the high resolutions.
• Supports one 10/100/1000BASE-T Ethernet PoE LAN output signal.
• Output resolutions follow input.
• Selectable audio encoding control from LPCM and AAC — LPCM offers a
fixed audio encoding bit rate while AAC features variable audio compression,
available to support different streaming bit rate requirements.
• Streams HDMI signals over IP networks.
• Encapsulates A/V output data into MPEG-2 transport stream. The program
number can be altered.
• Delivers TS data through UDP or RTP. Both unicast and multicast are
supported.
• Supports RTSP that enables a client entity to build a session and play the
media content. Up to ten RTSP sessions can work simultaneously.
• LAN (Web GUI and Telnet) control — VS-2000-ENC is controllable over
Ethernet, available for an intuitive web page control as well as Telnet CLI
control using API commands.

Chapter 2: Overview
• Uploads and encodes an idle pattern image file — Upload a BMP image file at
resolution 1920 x 1080, encode it, and allow it to be decoded on a third-party
decoder in times of no source received.
• Supports PoE to remotely power by a compatible power source equipment
such as a PoE switch, eliminating the need for a nearby power outlet.
• Capable of outputting IP streams that can easily be decoded and viewed on
third-party decoders. The multicast streams are output and can be received
and decoded by multiple decoders.
• Use with a third-party decoder such as a set-top box and a VLC media player
on PCs to provide complete end-to-end streaming systems.
• Support the following streaming transport protocols.
- RTP/RTSP streaming transport protocols may be applied, based on various
network conditions
- Native RTP and MPEG-2 Transport Streams - TS may be applied in unicast or
multicast streaming applications. TS may be transported over UDP or RTP
based on network conditions.
• Bonjour automatic discovery of VS-2000-ENC.
• Software upgrade through an embedded web page.
• Supports communications protocols used on the Internet such as TCP/IP, ARP,
DHCP, ICMP (ping), IGMP, Telnet, HTTP, RTP, RTSP, UDP.
• Rack-mountable 1U, half-rack width metal enclosure.
• Selectable audio encoding control from LPCM and AAC — LPCM offers a
fixed audio encoding bit rate while AAC features variable audio compression,
available to support different streaming bit rate requirements.
• Encoding quality controls including video bit rate and audio bit rate— two
user controls are available to adjust encoding quality.
2.3 What’s Included
• (1) VS-2000-ENC
• (1) 12-VDC, 1-A power adapter

NOTE: We recommend powering the VS-2000-ENC using either a power adapter or a PoE switch instead of using both at the
same time. For example, if you use a power adapter, make sure that the PoE function of the connected switch’s LAN
port is disabled or use a non-PoE switch.
