Video Sharing

is an IP Multimedia System (IMS)
enabled service for mobile networks that
allows users engaged in a circuit switch
voice call to add a unidirectional video
streaming session over the packet
network during the voice call. Any of the
parties on the voice call can initiate a
video streaming session.
File Sharing
Stands for "Peer to Peer." In a P2P network,
the "peers" are computer systems which are
connected to each other via the Internet.
Files can be shared directly between systems
on the network without the need of a
central server. In other words, each
computer on a P2P network becomes a
file server as well as a client.
 The only requirements for a computer to
join a peer-to-peer network are an Internet
connection and P2P software.

Common P2P software programs include:
Kazaa
Limewire
BearShare
Morpheus
Acquisition
BitTorrent
uTorrent
FrostWire
BitComet
Ares Galaxy
Is file-sharing illegal?
Whether file-sharing is illegal or not depends on exactly
what is being shared and under what circumstances. There
are certainly legal uses for file-sharing software. For example,
some musicians chose to make their music freely available on
file-sharing networks to try to generate interest in their
music. It is also legal to share works that are in the public
domain.
 However, it is generally illegal to use file-sharing software to
trade copyrighted music or other copyrighted works (e.g.,
movies, software, photographs, etc.) without the copyright
owner’s permission. In other words, it is the copyright owner
(whether a relatively unknown independent artist or a
record company which owns the copyright to a very well
known artist’s recordings) who is legally entitled to decide
whether to make their works freely available through filesharing.

ESTABLISHMENT OF
VIDEO/FILE SHARING
Video Sharing

Traditional methods of personal video
distribution, such as making a DVD to
show to friends at home, are unsuited to
the short, low resolution phonegenerated clips – and their burgeoning
number.

On the other hand, the increases in speed of
current broadband Internet connectivity are
well suited to serving the quality of video shot
on mobile phones, tablets and cameras.

Before Vimeo and subsequently YouTube
changed the way videos were hosted on the
web, the first Internet video hosting site was
www.shareyourworld.com (now closed).

Just like the modern hosting services, it
allowed users to upload clips, or full videos, in
different file formats.

YouTube is the third most visited website in the world
Over 800 million viewers visit YouTube at least once every
month
Over 4 billion hours of video are watched on YouTube every
month
72 hours of new video are uploaded to YouTube every
minute
70% of YouTube traffic originates from outside the US
YouTube has locations in 43 countries and carries content in
60 languages
In 2011,YouTube had more than 1 trillion views – or around
140 views for every person on Earth
Many file systems in use only supported short
filename. Computer memory and speed was
very limited.
 The very basic ideas involved with file sharing
were experimented with. Most of the
protocols (like BitTorrent) that were involved
in file sharing.
 Data compression technologies for audio and
video (like MP3, AAC and MPEG1) were only
usable by the general public towards

The 8-inch floppy disk, the first removable
magnetic medium.
 first Removable media, is developed by an IBM
team led by David Noble. It allows for manual
file transfer. It would become a target of media
industry efforts against the sharing of
intellectual property.
 Client and tracker software in this era was in
development as much as the transmission
protocols, so the file trading software was not
always as reliable as it could have been.
