WHAT IS IT?
Use
of
digital
whiteboard
,
allowing
interaction
among
all
session
users
;
Group
visualization
of
applications
(
with
transmission
of
the speaker's
image);
Ability
to
transmit
pre-recorded
videos
through equipments such as DVDs, VHS players, camcorders... ;
creation of play lists from pre-coded videos;
Chat
publicly
and the ability
to
exchange
messages
privately;
Ability
to include
users
with
different
transmission
speeds
(kbps)
in
a
videoconference
session.
By adopting
the IP.TV
solution, the
user
can
take
advantage
of
one
or
more
exclusive
channels
to
transmit
any
programming
to
the locations
of
his
choice
. The
number
of
locations
/
computers
that
can
have
access
this
programming
is limitless.

WHAT SETS IP.TV APART
SOLVING PROBLEMS OF HETEROGENOUS CORPORATE COMMUNICATION NETWORK WITH THE IP.TV * SOLUTION
|
* Article by Prof. Ricardo L. de Queiroz, University of Texas, author of nearly 100 journal articles, books and international conferences on processing and compression of images and videos.
|
|
| DESCRIPTION |
IP.TV VS. OTHER SOLUTIONS |
|
| End-point equipment (adaptation) |
Solution based on software “Client-Server” model. The equipments for the end-points are PC’s with respective available peripherals. In comparison with traditional solutions of videoconference, the IP.TV environment becomes more economic once PTZ cameras, white boards and document cameras do not need bundled Codecs.
|
|
| Use over different telecommunication circuits (isolated or combined) |
IP.TV guarantees the use in any kind of IP circuit, whether isolated or combined. It is possible for users to interact, in a single videoconference, through dial-up, ADSL, satellite, radio... on unicast or multicast circuits, simultaneously, if necessary - without needing any additional hardware
|
|
Simultaneous use by users with different
“bit-rates". |
IP.TV guarantees media transcoding through one of the functions of its Server software. This means users with different transmission rates can enjoy a videoconference session without being slowed down by the narrowest band.
|
|
| Customization |
As it is a solution based on software designed by its own team, IP.TV can evaluate possible customizations for specific applications.
|
|
| Number of simultaneous users |
The solution allows an unlimited number of users to access videoconference sessions simultaneously, eliminating the use of MCUs.
|
|
| Coding Standards |
The IP.TV solution allows users to use MPEG4 and H264 coding standards in a single videoconference session, enabling the use by Pentium III processors (MPEG4) as well as the best H264 coder on the market on Pentium IV. The IP.TV solution uses SPEEX to code videoconference audio (far superior to standards of the “G.7XX” series).
|
|
| Integrated resources |
IP.TV enables the use, in a single application, of integrated resources such as CHAT (private and public), digital whiteboards, fi lms, screen capture and fi le transfer.

THE IP.TV PLATFORM
IP.TV is the first operator of IP-based, interactive digital TV channels and networks.
Its platform consists of a solution that encapsulates a telecommunications structure, hardware and software, dedicated to managing transmissions of packages (small data units) through any IP circuit (dial-up, private line, ADSL, satellite, etc.).
Transmission from remote units is also available. In this case, a special bidirectional antenna is used. Easy to transport and assemble, these antennas can be attached to any average-sized passenger vehicle with simple adaptations.
Besides that, users that do not require any kind of collaboration have the IP.TV – VIEWER option.
See illustrations of the communication systems:
|
|
 |
| |
|
|
A - Point in local network :
Allows that a channel exists only in a local network. Optionally, with an internet link, this point also starts to interact with channels outside of this network. |
|
B - Point of unidirectional satellite :
Allows only the transmission receiving. Optionally, with an internet link, this point also starts to transmit. |
| |

IP.TV SOFTWARE
The software used by the IP.TV platform is made of the Server and Client modules and offers transmission of data packets as a Multicast or Unicast when necessary.
The IP.TV Server operates on Linux and Windows platforms; both are totally compatible. This way, it is possible to have some servers running Linux and others running Windows, with all servers transparently interconnected in a single network.
IP.TV Client is the application in which all the resources of the IP.TV platform can be viewed. The graphic navigation interface has a modern design, is extremely user-friendly and can be used in full-screen or mini. The available functions for the user are:
|

1.Conference
In IP.TV, the conference session provides a virtual room with areas for visualizing chat and a list of users present in the Room. The operations of the conference room are always mediated by a moderator, who will monitor the flow of conversation, media transmissions etc. This is not the case in chat, which is open to use by all users regardless of moderator permission.
By the way, any participant can be a moderator, as the moderator can delegate this role to any user present in the room. Participants can interact with the moderator through audio, video or digital whiteboard.
Participants operate the room using buttons that indicate requests for voice and/or image transmission, as well as participation in surveys. During videoconference sessions, surveys can be conducted in real time. Images transmitted are captured by a camera and the integration of participants occurs through the operation of IP-based voice/video.
There is no limit to the number of participantsin a session . Up to 7 simultaneous images can be created among the session participants. Any participant can occupy one of these 7 collaborative positions, allowing other participants to watch. It is the moderator's job to complete this operation.
|
|
|
|
|
|
|
|
|
 |
2a.Video
Participants can initiate transmission of images captured by cameras, camcorders, DVD/VHS, and similar equipment, which are then directly coded within the IP.TV application itself. |

4.White board
This function simulates the traditional classroom blackboard and can be used by any participant of the virtual meeting. The digital whiteboard includes buttons to control fonts, eraser, lines, cursor (arrow), image, highlighter, pencil, filled and empty rectangle, filled and empty circle, line thickness and colors. The whiteboard also includes new file, undo, record to disc and print commands. Anything done in the digital whiteboard is shared among all users that can edit content while other users watch. |
