Alice – Typographical Conventions
Welcome to Alice
1 Welcome to Alice
Alice is a user-friendly software package for the transmission
and reception of audio and video data. The seamless synchronization of video and sound data through the monitor
and sound card enables speech and moving images to be reproduced in high quality, both on your computer and the
computer of the remote station.
Alice allows video and sound connections to computers on
which Alice is installed, to video telephones, to video conferencing systems and to what are known as content servers
(image information services). Alice offers you several ways of
connecting to a remote site thanks to its support for various
standards. You can connect to an ISDN remote site with a direct ISDN connection over one or two ISDN channels. Alice
uses the H.320 standard for ISDN connections. You can also
establish an IP connection to a remote site using the H.323
standard. It does not matter whether the connection is within a LAN or over the Internet.
If a camera is connected to your computer, you have the option of transmitting your own local image to the remote site.
Alice can be used to call friends or business partners with
whom video images are to be exchanged to complement a
conversation.
If there is no camera connected to your computer, Alice can
still be used to view video transmissions from remote content servers.

Sound Card Information
2.2 Sound Card Information
Alice can be operated with a number of different sound
cards. You can use either headsets (headphones combined
with a microphone) connected directly to a sound card or
desktop speakers combined with a separate microphone.
AVM recommends using a headset to ensure that transmission is as free of distortion as possible.
Make sure that your sound card has full duplex capability,
i.e., that it can send and receive audio data at the same
time. Newer cards tend to be duplex capable, but frequently
this feature must be activated in the driver settings. For most
sound cards, this setting must be made in the Windows Device Manager. For more information on this subject, see the
manual of your sound card.

How Alice Works
4 How Alice Works
Using Alice you can establish connections to various remote
sites over the ISDN line or an existing network connection.
Alice can connect to video conference systems, content servers and remote sites equipped with Alice software or other
software compliant with the international standards H.320
and H.323.

How Alice Works
Alice receives audio data for transmission through a microphone and the full duplex sound card of your computer. Incoming audio data is transmitted to the speakers via the
sound card.
Alice can receive its own video data via a USB camera or a
video camera with a frame grabber card. A frame grabber
card is a supplementary adapter that transforms an individual image (a frame) from a video source (here the camera) into
digital data. The connected camera provides the video data
for the video interface. This is the interface to the operating
system from which the video data is sent to Alice.

Alice – 4 How Alice Works
Standards Used by Alice
4.1 Standards Used by Alice
Alice uses the following standards:
Standard
Description
H.320
An ITU (International Telecommunications
Union) standard. General term for all audio
and video transmission over ISDN.
H.323
An ITU (International Telecommunications
Union) standard. A package of standards for
audio and video transmission via IP
connections.
H.221 / H.225
These standards define the protocols with
which video and audio data is sent and
user-defined data is transmitted.
H.230
This standard defines audio and video
commands in the H.221 standard.
H.242
This standard defines how the B channels
are managed. It also describes the
protocols for establishing and clearing a
connection.
H.245
This standard defines a control channel
over which the properties of the connection
are negotiated.
H.261
Standard for video compression. H.261
supports the CIF and QCIF formats (see
below).
H.263
An improved standard for video
compression which requires less bandwidth
than H.261. H.263 also supports the QCIF
and 4CIF formats (see below).
G.711
A standard for audio coding. In this
standard a bandwidth of 56 kBit/s is
required for transmission of the audio data.
A number of remote sites allow G.711 only
for transmission with two B channels
(128 kBit/s), so that enough bandwidth
remains available for the transmission of
video data.
21
Standards Used by Alice
22
Standard
Description
AV-II
An AVM standard for audio coding. In this
standard a bandwidth of only 16 kBit/s is
required for transmission of the audio data.
The effective compression performed with
AV-II makes more bandwidth available for
transmission of the video data. AV-II also
offers improved audio quality thanks to the
increase in frequency range from 3 kHz to
7 kHz.
CIF
Common Intermediate Format; graphic
format with a resolution of 352 x 388 pixels.
QCIF
Quarter Common Intermediate Format;
graphic format with a resolution of 176 x 144
pixels.
SQCIF
Sub Quarter Common Intermediate Format;
graphic format with a resolution of 128 x 96
pixels.
4CIF
4 Common Intermedia Format; graphic
format of four times the CIF size, with a
resolution of 704 x 576 pixels.
MMX
MMX is available in all new Intel processors.
MMX is a processor extension that Alice
uses for intensive computing tasks. Only
MMX-capable computers can perform audio
coding in accordance with AV-II (see above).
Tips and Tricks
5 Tips and Tricks
This chapter provides you with useful tips on using Alice and
on solving problems that may arise during operation.
5.1 Selection of the Video Device: Alice
Does not Display a Local Image
Alice offers the option of switching among different cameras
during an active connection. If no local image is displayed
after you start Alice, it may be that Alice is using another video source installed on your computer. In this case, switch the
video source by pressing “Ctrl+T”.
5.2 Operation Behind a Firewall
If you would like to operate Alice behind a firewall, please
note the following:
Alice uses the video conference protocol H.323 for IP connections. In the firewall, the ports used for such connections
must be enabled for incoming and outgoing data. The TCP
port 1720 must be enabled for the control channel in accordance with the H.323 standard. While connecting, additional
UDP ports from the range from 1024-65535 are determined
which are then used for video and audio transmission. In
some cases these ports must be taken into consideration in
the configuration of the firewall. For information about the
settings necessary for an H.323 connection, please contact
the manufacturer of your firewall.
Alice – 5 Tips and Tricks
23
Dialing via an Internet Connection
5.3 Dialing via an Internet Connection
In order to connect to a remote site via the Internet, you have
to know its IP address. However, this address is usually assigned dynamically when you dial into the Internet Service
Provider. The current IP address of your computer can be
found in the Alice “Information” window. Contact your conversation partner by e-mail, chat or telephone and inform
them of the IP address at which you can be reached as long
as the connection is active.
Various Internet Service Providers offer the option of reserving a fixed host name at which a computer can be reached,
independent of the current IP address (dynamic DNS service). Where this option is available, additional software is
implemented on the computer to transmit the IP address assigned to a DNS server each time the computer connects to
the Internet. This means that the computer can always be
reached at the same host name.
For more information about dynamic DNS service, please
contact the corresponding provider.
