Seminar on : MPEG-4 – Mobile to HD

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, Doordarshan.

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).
