Videoconference tips
Tips to improve a virtual meeting, to optimize audio-video transmission and reception,
and to fully enjoy all videoconference benefits.
Optimal Meetings
• Before starting a videoconference be sure that all you need is ready: addresses or numbers to
call, lighting, microphones.
• Connect and test all peripherals eventually needed (document camera, VCR, PC/Laptop)
• Use natural gestures as in a real meeting
• Speak in your normal voice
Optimal Video
• Avoid contemporaneous usage of natural (changing) and artificial lighting
• Avoid direct artificial lighting
• Avoid “mobile” backgrounds (curtains moved by the wind)
• Try to fill the screen as much as possible with persons, not backgrounds
Optimal Audio
• Place the microphone on the table in front of people (use 2 microphones in case of big tables)
• Do not place papers or other objects in front of the microphone
• Don’t rustle papers or tap on the table or microphone
• Mute the microphone before moving it.
• Speak in your normal voice

For configuration information, please contact your network administrator.
!
C) Streaming Management .
In this menu the System can be configured to use streaming. This technology allows
viewing of and listening to live or recorded events by a large number of users
connected to the IP network without the need for a large file to be downloaded. It is
based on the continuous transmission of data compressed by particular programs
(systems) from a server, then decoded at the client side by an appropriate player that
works even during data buffering, thereby avoiding long delays.
The System is able to transmit to networks in either unicast or multicast. If the
streaming is unicast, only one client at a time is allowed to connect to the stream. If it
is multicast, there is no theoretical limit to the number of connected clients.
In case of pre-recorded event streaming, replay a recording of the event using a VCR
or DVD player connected to the System video input available for this purpose, select
this input and begin the streaming.
Note that the system does not act as a distribution server, rather as a simple system.
It does not provide connections using RTSP (Real Time Streaming Protocol), nor can it
provide unicast streaming to multiple clients, or offer other services typical of
distribution servers.
Streaming is supported by RTP (Real-time Transport Protocol). Video packets are
encoded in H.261, while audio packets are encoded in G.711.
64
Menu options are Streaming Management , Enable Streaming and Activation .
a) Streaming Management.
This option permits that the parameters Announcements, Video, Rate,
Address, Port and TTL can be modified by an external application (e.g. from
the Web).
If this option is not selected and a unicast IP address is present in the
Address, then only the system identified by that IP address would be able to
view the stream.
• Enable/Disable Enable all addresses .
If enabled allows la above parameters modification from every external system.
• If not enabled, you can define which system or sub-network is enabled to perform such an
operation.
Address mask the value is 255.255.255.255, a system is selected; if the value
If in the
is 255.255.255.0 the sub-network is selected.
Likewise, if in the
Address field a unicast type IP address has been set up, the limitation
also effects the visualization of the streaming.
• Password: allows password protection of streaming management
b) Enable Streaming.
This option permits the parameters Announcements , Video, Rate , Address ,
Port and TTL to be changed.
Allows stream viewing according to the limitations imposed by the parameters
“Streaming Management” and “Enable all addresses.” If this option is not
selected, streaming will never be activated.
Announcements. This drop-down menu allows you to choose how the
System will notify the user that an external system has requested streaming
activation.
Options:
• Activation: The System will display a dialogue box containing a warning
and a video camera icon that will stay in place as a reminder for as long
as streaming is active.
• Status: Only the video camera icon will be displayed during streaming.
• Confirmation request: A dialogue box will appear to request
confirmation of streaming activation. This option offers an extra level of
protection.
Video. This drop-down menu allows you to choose which video signal is
transmitted when streaming is active.
If the Automatic option is selected, the streaming content will be determined
by the status of the terminal: if the terminal is connected (in either a pointto-point or multipoint session), video coming from the remote site will be
streamed. If the terminal is disconnected, local video will be streamed.
If the Local option is selected, the system will always stream local video.
65
Rate. This drop-down menu allows you to choose the bandwidth occupied by
audio and video streaming. Note that if a rate of 64K has been selected, the
video will not be transmitted, because all the bandwidth will be occupied by
audio.
Address. This parameter contains the IP address for the stream. If this field
contains a unicast IP address, it will be automatically overwritten by the IP
address of the system that has requested to view the stream from an HTML
page supplied by an internal web server. By pressing the Active key on the
configuration page, you can activate streaming: the system will start the
transmission of audio and video packets to the selected IP address.
If the IP address is multicast, streaming will be sent to a multicast group
identified directly by the IP address, enabling viewing by a large number of
users (theoretically unlimited).
Port. This parameter contains the number of the UDP port where audio
packets are to be sent. Since the streaming content is RTP, data are sent to
four different ports: one port for audio, one port for video and two ports for
the RTP information corresponding to both streams. Therefore, starting with
an audio port number, it is implied that the audio data will be sent to this port
number, video data will be sent to the audio port number plus two, and the
odd port numbers before and after the video port will be used for RTP data.
For example, if the audio port number is 554, the port number for video will
be 556, and the port numbers for RTP data on both streams will be 555 and
557.
TTL/Hops. This parameter contains the value for the Time to Live associated
with multicast packets.
c) Activate
Streaming activation/deactivation request.
66
Viewing methods
Viewing with a plug-in
The integrated Web Server provides the simplest method.
Connect to the System via the Web and from the server homepage click on the
image that looks like video—this will give you access to the page produced by
streaming. This page has been designed to use Quick Time, which must have been
previously installed to view the video stream. Accessing the page automatically
activates audio-video streaming. The user can choose the video signal to be
displayed (Local or Automatic), which must be compatible with configured settings.
The System provides a direct link to streaming page, using the address:
http://aaa.bbb.ccc.ddd/ streamviewen.asp, where aaa.bbb.ccc.ddd is the IP
address of the System.
Viewing using an external player
Another way of viewing streaming is to use an external player. The only tested
players are QuickTime 6.0 and VIC (supplied by the University of California
Berkeley), but this does not exclude the possibility of compatibility with other
players that accept RTP streams.
The first operation necessary is to activate streaming. This can be achieved by
simply entering the IP address of the system in the “Address” field on the
streaming configuration page of the system where the player is located, or the
multicast address of the group to whom the stream is being sent. Pressing the
Activate key will enable the machine to begin the transmission of audio-video
packets to the player.
If you use QuickTime as a player, you can simply select “File” from the menu, then
“Open URL in new player” and enter http://aaa.bbb.ccc.ddd/stream.sdp where
aaa.bbb.ccc.ddd is the IP address of the System that is to send the stream.
Viewing using a Distribution Server
Distribution servers offer a range of services for stream management that the
System cannot offer directly. If users would like to make use of a distribution
server for streaming transmission sent from a System, they can do so in
accordance with the server’s characteristics.
Using a Proxy
Multicast streaming transmissions require an appropriate network configuration,
with limitations imposed by the presence of any Firewall or Proxy. To offer good
protection, these must block IP packets directed to unknown ports, such as the
UDP ports used for audio and video streams. If the stream has to pass through
such equipment, the equipment must be configured for any eventual multicast and
have the appropriate ports enabled for streaming.
If the stream is sent over an internal network, problems can still arise if it is
necessary to pass through a firewall in order to gain external access.
Deactivate Streaming
In order to stop streaming, go to the Deactivate key on the streaming
configuration page and press OK, or simply close the browser.

Appendices
IP Network Requirements for Videocommunication
The network requirements for point-point connections between IP videoconferencing
terminals are as follows.
The complete network path connecting two IP terminals must have a constant
available bandwidth for the whole duration of the connection. The effective bandwidth
used on LAN/WAN Full-Duplex network connections is equal to the sum of the Audio
Rate and Video Rate, plus approximately 20% for TCP/IP overhead.
In the case of Half-Duplex LAN/WAN networks, the aforementioned bandwidth is
doubled. For example, if it is necessary to guarantee a 384K connection for the video
and a 64K for the audio, the bandwidth allocated must be at least (384+64) *1.2 ≈
540K for each Half-Duplex connection. In case of dial-up WAN links, it should be
underlined that their efficiency in terms of “useful” bandwidth is approximately half
the total available bandwidth.
It is always preferable to use mechanisms such as QoS for WANs because they take
into account the total bandwidth required for a videoconference, rather than relying
exclusively on over-dimensioning the network. This is necessary for the handling of
increasing numbers of simultaneous connections or a network that is already loaded.
The network needs to be set up so that latency and jitter are as low as possible.
Extended times for latency and variable jitter can create serious problems, especially
in video quality.
It is always preferable for IP terminals to be connected to switched type LAN
connections to avoid the traffic generated by terminals being superposed on the
normal traffic present on the network.
It is preferable to avoid using NAT-type protocols on router interfaces that route IP
packets, since NAT protocols often do not allow the correct routing of connections.
If NAT, firewall or access list implementations are to be used, they must be IP
compatible.
NAT – FIREWALL Interoperability
Introduction
There are many strategic advantages for companies that succeed in making all traffic
converge from voice applications, video and data to one IP network infrastructure.
Unfortunately, the drive to concentrate all IP communications onto one single network
has reduced. The connection between a company’s corporate network and the Internet
world is accomplished with firewalls and devices using NAT (Network Address
Translation), which block voice and video calls via IP. Firewalls block IP traffic for
video and voice by preventing any unsolicited communication from the outside.
Devices implementing NAT block IP traffic because all equipment on the internal
network uses private IP addresses, and can therefore not be contacted from outside
the local domain.
There are several solutions to the problem of getting IP communications past NAT and
firewalls: bypassing the firewall or NAT device, upgrading the network infrastructure
with an Application Level Gateway (ALG), and going out through the firewall or NAT
using semi-tunneling connections.
