Personalized Transmission of 360° Video

According to some studies, 80% of internet traffic will consist of video by 2019. And that number will only increase once 4K and 360 degree video become mainstream.

To avoid that our communication networks collapse under this strain, researchers from imec - IDLab - Ghent University have developed a number of solutions that start from the assumption that forwarding complete 360° video streams to each individual user does not make sense. Instead, it is much more efficient to transmit only the parts that are actually being watched. Yet, doing so would require a lot of encoders (processing power), i.e.  one encoder per individual. 

In this demo, an imec - Ghent University research track is presented that has resulted in a unique processing strategy to generate an individual video that follows the head movement of the user without needing a full video encoder to generate the video. The technology is applicable to any ‘Region-Of-Interest’ or individualized video transmission strategy and works after analyzing the full video once. After this analysis, individual videos can be encoded with 99% less processing power compared to an encoder that is not able to make use of such an analysis.  This reduction in processing power makes the strategy of one personalized transmission per individual feasible in 360 degree video applications of the future. Finally, the actual benefit is that data is only being transmitted for visible regions instead of the entire 360 degree content.
