StreamerOne
goes into the audio video broadcast field. In other words, everyone
will be able to make his/her own TV.
What
is StreamerOne
StreamerOne is a web broadcasting system able to distribute
high quality audio/video streaming to a theoretically unlimited
number of contemporary users.
Till yesterday the broadcasting on internet of live or TV events
that would involve thousands of users at the same time was pure
fantasy. As a matter of fact, video distribution through conventional
(unicast) streaming on internet is deeply influenced by technical
parameters referable as:
Provider’s capability to digitally connect to internet
backbone
Processing capability of the streaming server(s)
This implies unicast service supply costs are directly proportional
to the number of users to reach and to the quality (number of
pixels per frame, number of frames per second) of the video
to distribute.
StreamerOne is the first P2P streaming system to use a completely
Italian technology making available its international experiences,
know-how and infrastructures in order to meet professionals’,
companies’ and organizations’ requirements.
Technology
Unrestricted number of user and superior image quality are the
main features of StreamerOne, made achievable by the use of
Peer to Peer technology applied to video flow distribution.
In practice the stream source starts fragmenting and supplying
the flow to a limited number of users, who in turn re-distribute
it to other ones who get connected through a mechanism of cascade
sharing. Sophisticated algorithms manage users connection and
disconnection to the streaming, while data exchange between
source and peerer is secured by the use of public and private
key.
Original flow quality is unimportant.
However, it is worth considering the kind of internet connection
the target users may have. For instance, for ADSL connections
with an upload nominal speed of 512 kbps a flow of 280kbps is
preferable, corresponding in terms of video quality to VHS with
FM audio.
In order to display the streaming, user needs installing a player
made for the purpose of activating P2P both with Windows Media
Video(WMV) and Real Player (RP) flows. The player is offered
as free-ware.
Once the player is active, user has to wait a few seconds to
access the system and to start receiving the video signal without
any interruption. The main feature of this P2P utilization mode
compared to file sharing systems, often blamed for copyright
violation, consists in the public acquaintance of the video
flow source which is unique, known and identifiable beyond any
doubt.
Services
Services connected to the use of StreamerOne are addressed to
those operators who intend sharing out through internet, in
a continuative or simply occasional way, high quality video
contents to an unrestricted number of users:
