Broadcast Engineers Society (India) organized a workshop
on MPEG-4 – Mobile to HD on 24th July 2006 at Hotel Le Meridien
, New Delhi, which was sponsored by M/s. Shaf Broadcast Private
Limited. The workshop was chaired by Mr. N.S. Ganesan, Engineer-in-Chief,
Mr. A.S. Guin, President, BES(I), while welcoming
the speakers and the delegates narrated the objectives of the society
i.e. to promote and encourage education, research and training in
broadcast engineering and science. He said that digital radio (DRM),
mobile TV and High Definition TV are the buzz words of the broadcast
industry today and if one looks at the technology behind these happenings,
we find MPEG-4 to be present everywhere. Compression remains the
field of great interest among broadcasters as the race for more
channels with diminishing spectrum persists. The research is on
and works are going ahead on standardization of better technologies
such as MPEG-7. While emphasizing the relevance of the topic, he
wished that the workshop will succeed in throwing some light on
the prevailing compression technology MPEG-4.
Mr. R.R. Prasad, Chairman, Siminars and Lectures
Committee, BES(I), in his speech, assured that such thought provoking
deliberations will continue under the banner of BES and will definitely
benefit the broadcasters of our country.
Mr. N.S. Ganesan, while opening the technical
session, remarked that MPEG-4 has brought a revolution in broadcast
world. It is the technology behind digital TV, broadcasting to mobile
and IPTV. Apart from spectrum efficiency, this technology has brought
a complete transformation in the contribution and delivery of audio
and video signals.
The keynote speaker of the workshop was Mr. Julien
Signes, President and Chief Technical Officer, Envivio INC., USA.
Mr. Signes is a renowned authority of MPEG-4. He is one of the architects
who contributed in development and standardization of this technology
and has been awarded many patents linked to his standardization
work and has received distinctions from ISO and SPIE. While elaborating
the history of development of MPEG-4 spanning for a decade now,
Mr. Signes talked of many new applications based on MPEG-4. He said
that the usage of digital video has completely changed. One has
to cater to varied needs of broadcasters and Telcos and IP and MPEG
are the best suited technologies of the day. Whereas the conventional
technology requires different encoders for different services, the
use of MPEG may lead to convergence and thus resulting in less capital
cost. In his speech, he covered the bandwidth requirement for various
services such as SDTV, Mobile TV, IPTV, HDTV etc. and suggested
how MPEG-4 compression can lead to spectrum efficiency.
Mr. J.M. Kharche, Speaker from Doordarshan (India),
talked at length about the plans of Doordarshan in the field of
DVB-H and VSAT terminals for contribution and distribution of video
signals. He stated, how Doordarshan is going to employ MPEG-4 technology
in times to come.
Mr. Pawan Gandhi, the Speaker from Nokia, Singapore,
gave some market surveys indicating that the television on mobile
is the natural choice of viewers. More than 70 percent of them wished
that mobile TV should be a reality now and a large percentage was
ready to pay for it. He stated that the products to receive mobile
television are already in the market and the technology is going
to sweep the world.
The function ended with a vote of thanks delivered
by Mr. Ashish Bhatnagar, Hon. Secretary, BES(I).
