CELTIC PLUS Project
KEYWORDS: Video transmission, Power saving, Video processing architectures, Encoding, Decoding
The concept of the CONVINcE project grew out of two observations. That the Internet’s carbon footprint would exceed that of air travel by a factor
of two by 2020 and that Internet traffic is driven by video. The sum of all forms of IP video will be 80% to 90% of total IP traffic in 2017.
Furthermore, should people not be convinced of the necessity to reduce carbon dioxide emission, they will listen to the economic aspect of the
problem: The price of electricity is increasing and will still increase in the coming years.
CONVINcE will address the challenge of reducing the power consumption in IP-based video networks with an end-to-end approach, from the Head
End where contents are encoded and streamed to the terminals where they are consumed, embracing of course the CDN and the core and access
The partners’ efforts will concentrate on architectures, hardware and software design, protocols and basic technologies in the devices. In parallel to
these activities focussed on optimizing the power consumption in each part of the system, the project will run transversal activities on “Software
best practices & Eco-design” and “Power & QoE measurements”.
VTT will study the effect of video computing in both the head end and mobile terminals on power consumption and to develop solutions for them.
We will evaluate the effect of the architecture, execution parameters, and software to power consumption as well as study possibility of applying
our REPLICA architecture (http://www.vtt.fi/sites/Replica) to video workloads by outlining/preliminary evaluationg an application-specific version of it.
Project’s results will be visible through demonstrators targeting tests which conclusions will be made public in order to disseminate the best
practices in the domain. It is also the intention of the project to push its results to standardization bodies.
New knowledge, power-aware solutions, architectures, possibly intellectual property for designers, manufacturers, and users of video computing. In
the larges scale, these will help the society to reduce the carbon footprint in video transfer.
The specific business impact of the project will be the further delivery of new products and services designed from the beginning with aggressive
power reduction objectives.
