The end result of this project is to lay the groundwork for the development of Internet-enabled quality video services for the end user, which today represents a quantum leap in user experience and a benefit to operators and Internet content providers.
The project aims to:
- Characterize the design of the Internet to offer video services with a measurable high quality User Experience similar to today's DTT and IPTV, CATV or satellite as deployed by the Operators or DVD.
- Develop a new image and video coding system that can meet the Internet user's experience on any fixed or mobile access network. This will reduce the cost per byte, increase the capacity of existing networks and improve the user experience.
It is estimated that 40% of Internet traffic today corresponds to video content, progressing to 60% over the next four years. This content originating from all sources: from P2P, Video On Demand to regular broadcasts of established TV channels. This is compounded by the expected development of the performance of High Definition and 3 Dimensions.content:
Concurrently the new digital televisions incorporate Internet connections for viewing such content, providing us with the scenario: Internet Video presented in the TV set.
All this raises the challenge of providing such content to the viewer with the same Perceived Quality or Quality of Experience as is usually received from the classical distribution channels: DTV, CATV, satellite, DVD, etc..

Abstract Title : Wavelet Quality Logarithmic Coding at the price of DPCM.

Among various image compression techniques a new coding algorithm called " LHE " ( Logarithmical Hopping
Encoding) based on logarithmic leaps in space domain has been presented in this seminar. The codec is
patent-free and has been developed within the project VideoXperience.
Its computational cost is as extremely low as differential coding (DPCM ) but the results outperform the DCT at high and low bit-rates .
This technology is applicable to not only for still images but also opens the possibility of
standard video coding at low computational cost without penalizing the latency in
applications such as online gaming or videoconferencing .
