Internet TV is basically defined as the ability to view video streams over the Internet. The primary models for Internet television are streaming Internet TV or selectable video on an Internet location typically a website. While in the past reduced bandwidth has confined the images to small windows
and grainy resolutions, newer codecs like DivX and increased speeds of
broadband have created extremely high quality images in sizes around
320 by 200. As the size of the images increases, the size of the
picture points also increases creating a less defined picture. To a
great degree, this reflects more of an attempt to save the costs of
streaming bandwith than the technical ability of generating a clear
picture streamed full screen over the Internet.
Today - with the increase in Internet
connection speeds, advances in technology, the increase of total number
of people online, and the decrease inconnection costs - it has become
increasingly common to find traditional television content over the Internet. In addition to this, new Internet-only television content has appeared. Very few cable and satellite television
stations stream the same content over the Internet, thus protecting the
cable systems' contracted "right of first use" for the content.
Some of the ways in which Internet delivered television
is used include watching on a regular TV (via a direct connection from
a computer or a Set-top box), or on a computer, or on a portable device
(such as a mobile phone) show a channel 'live' (like regular TV), or
allow the viewer to select a show to watch on demand ("Video-on-Demand"
or VOD). The viewing model for Internet TV includes interactive pages with embedded video streams or passive or streaming medium that is representative of broadcast television. The technology of Internet television is no longer as limited by the previous barriers of technology as itonce was. It used to be that one of the barriers towider adoption of Internet television was streaming technology
and bandwidth limitations. The bandwidth issue primarily meant that
streams were using lowbandwidth and that resulted in poor
quality.Increasing the bandwidth for the stream being broadcast
resulted in a high cost to the providers. Many sites that stream Internet broadcasts have moved to using Flash for videos since it employs vector graphic technology as opposed to turning every bit onand off. Many sites utilize the built-in media playerto display the streamed video.
Companies
are also developing transmission of existing pay-TV channels to regular
TV sets over the net whileprotecting the existing subscription and
pay-per-view business models. There is also a concern over copyright
associated with the digital distribution video. There will also be asubstantial challenge to the protected delivery of television by cable as they face challenges from a wide variety of content providers. The models for broad internet television adoption are still on the cutting edge. The technology is less the issue today than the fact that watching televisionover the Internet
is not commonplace. It suffers from a lack of a directory of available
shows and show times for a wide selection of streaming sites. There is
less generalized marketing of Internet TV than of broadcast television. Lacking a TV Guide for Internet TV, it becomes harder to know what to watch and when.
There
are still limitations in knowing what is being streamed at non-VOD
sites, so tuning into those sites is truly a hit or miss proposition.
Video on Demand or VOD offers a different approach and it is
interactive; requiring the viewer to select specific videos to watch.
This model is physical easier to do sitting at the terminal you are
watching on than to watch on the family television. Few televisions are directly connected to the computer orInternet as a television source. Some sites are working to improve the Internet television model by centralizing access to myriad of existing resources in a single site.
http://www.fantasy-tv.com is an example of a site that integrates web tv
resources into a single source resource forfinding streaming internet
TV and VOD. The requirement of remembering hundreds of web ids is
reduced to asingle site with links to the sites providing Internet TV.
