|
|
|
|
<P>More than 30 years ago Internet didn't exist. Interactive communications
|
|
were only made by telephone at PSTN line cost.
|
|
<P>Data exchange was expansive (for a long distance) and no one
|
|
had been thinking to video interactions (there was only television
|
|
that is not interactive, as known).
|
|
<H2><A NAME="ss2.2">2.2 Yesterday</A>
|
|
</H2>
|
|
|
|
<P>Few years ago we saw appearing some interesting things: PCs to
|
|
large masses, new technologies to communicate like cellular phones
|
|
and finally the great net: Internet; people begun to communicate
|
|
with new services like email, chat, etc. and business reborned with
|
|
the web allowing people buy with a "click".
|
|
<H2><A NAME="ss2.3">2.3 Today</A>
|
|
</H2>
|
|
|
|
<P>Today we can see a real revolution in communication world: everybody
|
|
begins to use PCs and Internet for job and free time to communicate
|
|
each other, to exchange data (like images, sounds, documents) and,
|
|
sometimes, to talk each other using applications like Netmeeting
|
|
or Internet Phone. Particularly starts to diffusing a common idea
|
|
that could be the future and that can allow real-time vocal communication:
|
|
VoIP.
|
|
<H2><A NAME="ss2.4">2.4 The future</A>
|
|
</H2>
|
|
|
|
<P>We cannot know what is the future, but we can try to image it
|
|
with many computers, Internet almost everywhere at high speed and
|
|
people talking (audio and video) in a real time fashion. We only
|
|
need to know what will be the means to do this: UMTS, VoIP (with
|
|
video extension) or other? Anyway we can notice that Internet has
|
|
grown very much in the last years, it is free (at least as international
|
|
means) and could be the right communication media for future.
