|Workshop on Video and Image Coding and Applications (VICA)
Geneva, 22 - 23 July 2005
Opening Address by Mr. Houlin Zhao,
Director, Telecommunication Standardization Bureau,
International Telecommunication Union
Opening of the Video and Image Coding and Applications Workshop
22-23 July 2005
Dear Ladies and Gentlemen,
It is my pleasure to welcome you here for this interesting and important workshop, which will go through the past,
present and future of video and image coding standardization, and their application and adoption by the market.
Video and image compression are indeed a very important technology area, not only from a telecommunications
perspective – here I can cite videoconferencing; cable, terrestrial and satellite television broadcasts; 3G
mobile communications; NGN multimedia; and webcasting over the net – but also for the consumers’ industry market –
video-CDs, DVDs, the new high capacity DVDs, cameras, surveillance, medical imagery, and digital cinema. These
are just a few, and the possibilities are huge.
I am happy that Study Group 16 organized this workshop and involved other organizations also working in this field.
Cooperation with other bodies is a basic premise of ITU-T work. ITU-T has for a long time cooperated with
ISO/IEC JTC1/SC29, the home of JPEG and MPEG, with whom we have developed many Common Text and Aligned Text
standards. JPEG, as some of you know, started many years ago and till this day is a joint group between ITU-T and
ISO/IEC, producing the JPEG / T.80 and JPEG2000 / T.800 families of image compression standards. MPEG and ITU-T are
also good friends; the MPEG2 video coding technique, also known as H.262, was jointly developed with ITU-T. More
recently, ITU-T and MPEG teamed up in the Joint Video Team to produce this recent, amassing success, the H.264
Advanced Video Coding, also known as MPEG4 Part 10.
I am particularly proud with the results of the JVT, as it was able to significantly increase the coding efficiency
compared to earlier generations of digital video standards; this was accomplished using
an open, inclusive development model, where the team of core ITU-T and ISO/IEC experts was enlarged by substantial
participation of the academia. The group managed well to strike a good balance between innovation and need to
deliver practical results. This is an example to be followed.
Before closing, I wish to thank the speakers and session chairs, many of whom are active in our standardization
work, for being present here and sharing their knowledge with us, and the steering committee for the hard work
over the past seven months in organizing and bringing together this event with the assistance of the TSB secretariat.
With no further ado, I would like to leave you, ladies and gentlemen, to dive in the interesting and well prepared
presentations that will follow today and tomorrow, and to wish you a fruitful stay in our city.
