AVN422 User’s Manual Chapter 1 Introduction
1
Chapter 1 Introduction
Visionary Solutions' IPTV encoders can turn video from HDMI or DVI-D sources into full-screen,
full resolution, Internet Protocol (IP) digital video in real time.
The AVN422 encodes high or standard definition video in an h.264 stream (MPEG-4 Part 10/
AVC). It is used in a Media Processing Platform (MPP), a high density rack mount system. Plug a
video source directly into the blade, plug into the network via the RJ-45 connection, and stream
real-time high or standard definition video over your LAN or WAN. The MPP with AVN blades is
suitable for all applications requiring cost-effective, low bit rate, high or standard definition video
distribution over IP networks.
1.1 Features
•Modular Flexibility. The AVN422 features modular firmware architecture, which lowers the
base price by allowing the user to purchase only those features they need at the moment,
while at the same time maintaining the flexibility to upgrade in the future as requirements
change. The list of optional add-on-modules currently include 720p, 1080i (with 1080p
@24 support), 1080p @60, and Forward Error Correction (FEC).
•Superior Audio/Video Quality. h.264 (MPEG-4 Part 10/AVC) hardware compression and
Visionary Solutions’ optimized transmission technology provide a high or standard definition,
full frame rate, IP video stream. The stream can be viewed by an unlimited number of clients
on a LAN or WAN provided that bandwidth is available. Image resolutions are configurable
based upon purchased modules. The base model includes 480i SD encoding. Optional
modules allow FEC support and image resolutions to be configured up to 720p, 1080i (with
1080p @24 support) or full 1080p at 60 fields per second. The total bit rate can be configured
from 4 to 20 Mbps for HD and 2 to 10 Mbps for SD. The audio compression is either AAC (32
to 384 kbps audio encoding, average bitrate) or MPEG-1 Layer II (32 to 384 kbps audio
encoding) with up to 48 kHz sample rate.
•Forward Error Correction (FEC). For superior image quality and reliability in the most
demanding network video environments, the AVN422, with an optional FEC module,
incorporates SMPTE-2022 Pro-MPEG FEC Code of Practice # 3, Releases 1 and 2. This
allows FEC enabled receivers to monitor the stream and recover missing packets.
•Video Inputs. The AVN422 includes one HDMI input (DVI-D with optional adaptor cable) for
connecting video and audio source equipment.
•Audio Inputs. A terminal block connector provides audio inputs for Balanced and
Unbalanced connections. This allows for easy onsite connections regardless of the cabling
outputs of the audio source. The HDMI input can carry audio as well. See sections 2.1.1
AVN422 Front Panel and 6.4.2.2 Audio Input Control for additional information about
unbalanced audio inputs.

Chapter 1 Introduction AVN422 User’s Manual

•External Device Connections. The AVN422 includes a serial connection via an RJ-45
connector. This connector can be used as an RS-232 port (full duplex, no hand shaking) or
an RS-422 (full-duplex) port. These ports allow the AVN422 to interface with external devices
such as terminal emulation equipment.
•Management and Configuration. The AVN422is easy to access and configure through the
Browser Interface, and an optional AVN Control Protocol (API) is available for qualified
customers. TCP/IP, HTTP, and other Internet-related protocols are supported. The Console
Interface can be used for network configuration only (IP Address, Netmask, Gateway, and
DNS), and not general device control.
•IPTV Media Processing Platform (MPP) Component. The AVN422 is a component of the
MPP from Visionary Solutions. The MPP is a high density rack mountable blade system. The
MPP1700 platform holds up to 17 single slot encoder blades, or a combination of dual and
single slot blades. The MPP200 has a single power source and can hold two single slot
encoder blades or one dual slot blade. Each MPP will incorporate a growing family of
modules to support transport, switching, transcoding, and monitoring of IPTV.

AVN422 User’s Manual Chapter 3 Connecting to the Network

Chapter 3 Connecting to the Network
3.1 Unicast and Multicast Transmissions over the Network
A Unicast transmission sends IP packets to a single recipient on a network. A Multicast
transmission sends IP packets to a group of hosts on a network. If the streaming video is to be
distributed to a single destination, then you would start a Unicast stream by setting the
destination IP address and port on the AVN equal to the destination's values. If you want to view
the stream at multiple concurrent locations, then you would set the AVN's destination IP address
to a valid Multicast IP address (224.0.0.0 - 239.255.255.255).
Note that while the Multicast IP address range is from 224.0.0.0 - 239.255.255.255, the first octet
(224.xxx.xxx.xxx) is generally reserved for administration. VSI recommends setting the first octet
to 225 and the remaining three octets to the AVN's IP address. For example, if the AVN's IP
address is 192.168.1.53, then set the destination IP address to 225.168.1.53 for Multicast
streaming.
Since Multicasting is a relatively new technology, some legacy devices that are part of your
network might not support Multicasting.
Before using the AVN422 in Multicast streaming mode, check the functional specifications of your
network infrastructure to ensure that the Multicast stream will not create major traffic on your
network. Verify that your backbone switch supports Internet Group Messaging Protocol (IGMP)
snooping, which allows the core of your network to ignore the traffic streams that Multicasting
may generate.
3.2 IGMP Querying and IGMP Snooping
IGMP is a session-layer (Layer 3) protocol used to establish membership in a Multicast group
and can register a router to receive specific Multicast traffic. (Refer to RFC 1112 and RFC 2236
for information on IGMP versions 1 and 2.)
Multicast aware switches are slowly making their way into the network cores for businesses and
universities that have heavy traffic to move through their networks. Multicast filtering is achieved
by dynamic group control management. By default, all Multicast traffic should be blocked until
requested by a Multicast group member. (Default behavior depends on switch manufacturer.)
The master of the IGMP filter lists is the router or switch that is configured to act as the IGMP
Querier. The responsibility of the Querier is to send out IGMP group membership queries on a
timed interval, to retrieve IGMP membership reports from active members, and to allow updating
of the group membership tables.
A Layer 2 switch supporting IGMP Snooping can passively snoop on IGMP Query, Report, and
Leave (IGMP version 2) packets transferred between IP Multicast routers/switches and IP
Multicast hosts to determine the IP Multicast group membership. IGMP snooping checks IGMP
packets passing through the network, picks out the group registration, and configures
Multicasting accordingly.

Chapter 3 Connecting to the Network AVN422 User’s Manual
8
Without IGMP Querying/Snooping, Multicast traffic is treated in the same manner as a Broadcast
transmission, which forwards packets to all ports on the network. With IGMP Querying/Snooping,
Multicast traffic is only forwarded to ports that are members of that Multicast group. IGMP
Snooping generates no additional network traffic, which significantly reduces the Multicast traffic
passing through your switch.
If your network distribution core does not support IGMP Querying/Snooping, the AVN streams
will still function as designed but your network may be subjected to high traffic loads and
condensed collision domain due to the broadcasting action used by the older switch or hub. If this
is the case, you may wish to isolate the streaming nodes within the network so that the streams
may be viewed without crossing the normal network traffic along its path.
Otherwise, for a general performance improvement, you may consider upgrading your network
core to a switch that is Multicast aware.
3.3 DHCP IP Configuration
The AVN422 has Dynamic Host Configuration Protocol (DHCP) enabled as the factory default. If
your network has a DHCP server on it, the AVN422 will automatically acquire an IP address. If
the AVN422 is not able to find a DHCP server, it will default to the IP Address, Subnet Mask and
Gateway that are configured into the unit. The factory default IP address is 192.168.1.253.
To disable or enable DHCP on the AVN422, use either the Console Interface (refer to section 5.1
Establishing a Connection) or the Browser Interface (refer to section 6.5.3 Device Network).
To assign a static IP address for the AVN422, refer to the following section.
3.4 Static IP Configuration (Recommended Configuration)
If the AVN422 is not able to find a DHCP server, it will default to the IP Address, Subnet Mask
and Gateway that are configured into the unit. The factory default is 192.168.1.253.
It is strongly recommended that the AVN422 be statically configured to a specific IP address.
This enables the AVN422 to be consistently found at the same address. Prior to statically
configuring the AVN422, check with your IT department and/or make sure the IP address to be
assigned is not in use by any other device on the LAN.
To assign a static IP address to the AVN422, follow these steps:
1. Power on the AVN422 blade and connect the console (light blue) and the network cables.
2. Run a terminal emulation program such as TeraTerm to communicate via console (refer to
section 5.1 Establishing a Connection). Use the following communication parameters: Bits
per second (38400), Data bits (8), Parity (None), Stop bits (1), Flow Control (None).
3. Press Enter to get the login prompt.
4. Log in to the unit with the valid username/password (by default admin/admin).

AVN422 User’s Manual Chapter 3 Connecting to the Network

5. An unconfigured unit automatically starts the Network Configuration Wizard, and will prompt
the user to enter an IP Address, Netmask, Gateway, and DNS Server.
6. Once the values have been entered, the AVN422 should reboot and be accessible at its
newly assigned address. Type the unit’s IP address into a browser (http://xxx.xxx.xxx.xxx) to
bring up the AVN422’s Browser Interface (refer to Chapter 6 Using the Browser Interface).
7. For previously configured units, press “n” and then Enter from the Console Interface to
unlock the display and start the Network Configuration Wizard (see step 5 above).
8. Units can be reconfigured at any time using the Console Interface as described in the
previous step.

4. After valid authentication, the Console Interface will display on your monitor.
5. The first time you log on, you will need to configure your network settings (see 5.1.1 Initial
Network Configuration Settings).
5.1.1 Initial Network Configuration Settings
An AVN422 is considered to be either configured or unconfigured depending upon previous
actions.
— An unconfigured unit does not have any network configuration settings. When the
Console Interface is opened for the first time, the Network Configuration Wizard
automatically appears and prompts the user to enter four pieces of information: the IP
Address, Netmask, Gateway and DNS Server values.
— A configured unit is one where the network configuration settings have been entered
and saved. When the Console Interface is opened on a configured unit, it will display the
basic network information about the unit and that it is in a “Locked” state. To change any
of the current values, the user will need to unlock the Console Interface and activate the
Network Connection Wizard. Doing this will automatically resets the network
configuration settings back to the unconfigured state.
