Improved video compression translates directly into lower requirements for storage space and network speed. Our work would therefore enrich your every-day media experience by enabling you to:
Furthermore, lower requirements for storage and transmission will allow for content providers to deliver an even larger variety of video entertainment at a much reduced price for you.
We are always interested in your views and opinions. So, if you are interested in PROVISION and would like to share your ideas with us, please find more information here:
PROVISION for the industry
PROVISION for the public
PROVISION is a network of leading academic and industrial organisations in Europe comprising of international researchers working on the problems plaguing most video coding technologies of the day. The ultimate goal is to make noteworthy technical advances and further improvements to the existing state-of-the-art techniques of compression video material.
The project shall not only aim to enhance broadcast and on-demand video material, but also produce a new generation of scientists equipped with research and soft skills needed by industry, academia and society by large. In line with the principles laid down by Marie Skłodowska-Curie actions of the European Commission, PROVISION is a great example of an ensemble of researchers with varied geographical and academic backgrounds all channelling their joint effort towards creating a technologically, or more specifically a 'visually' better tomorrow.
Our main goals are to:
Whenever you watch videos on your TV, your computer, tablet or phone, the video material is compressed to allow you to watch high quality videos. Uncompressed videos would require too much data. Downloading just a few minutes of content would take hours or even days. Video compression can reduce videos to more manageable sizes while maintaining the visual quality.
Digital videos are composed as sequences of pictures, called frames, played in fast succession, i.e. 30 frames per second. To reduce the video size video compression removes redundant information.
There are a lot of pictures you see in only one second. Those individual images vary only slightly and have a lot of similar content. This content doesn’t need to be encoded twice. We can remove similarities and encode only the differences. After all the redundancies are removed, the result takes far less data than the original uncompressed video while maintaining the same quality.
The human visual system has many perceptual properties that can be exploited for improving the efficiency of video compression. As an example, we are more sensitive to a certain level of contrast, movement and colour and this information can be exploited by vide encoders. When we watch videos, we do not focus on the whole scene, rather only on small parts. Modelling our visual attention, video encoders can put emphasis on those parts and use this information in the encoding process. Furthermore, we can use the fact, that we are very familiar with certain kind of textures, like water or leaves. We can recreate these parts instead of encoding them, without the loss in perceptual quality. PROVISION explores all those characteristics, working towards perceptually optimized video compression.
