Broadcast media, such as television and radio, are more pervasive
than internet especially in the developing countries like India.
Distributing internet content over broadcast media is an important
application because of broadcast media's comprehensive population
coverage. HP Labs India has developed an architecture to distribute
internet content along with the audio visual stream over a broadcast
medium.
The receiving end in the architecture could be either a TV set
or a PC. The existing broadcast network is used to broadcast
data that can be received, stored, retrieved or printed depending
on the need or the availability of resources. A broadcaster
can insert internet content dynamically into an audio visual
stream and distribute it anytime during the course of broadcasting.
The interface has been designed in a way such that internet
content insertion and distribution can be done by just clicking
a button on the IE toolbar.
This technology has the ability to augment the TV viewing experience
with a print artifact without disrupting it. In order to experience
TVPrintCast the broadcaster has to have content specifically
designed and created for broadcast. The viewer will require
a printer attached to the TV set through a TVPrintCast interface
– a Print ready Set Top Box.
Television is often attributed with the facility to grab attention,
while print is often associated with being more persistent.
We believe that the ability to provide audio-visual along with
Print in a synchronous manner will not only make it possible
for these media to complement each other but will also greatly
impact the use of these broadcast media such as distance education.
This ability to synchronously deliver audio visual and print
will not only impact the effectiveness and the reach of these
distance education programs, but will also impact how content
is created and developed for this new medium.
The technology is not restricted to sending print artifacts.
With this technology the broadcaster can also send non-print
artifacts like a ringtone or a video clip that can be downloaded
at the viewers end onto a BlueTooth enabled hand held device
like a mobile phone.
TVPrintCast technology has received UN recognition for mass
communication.
