  • THE FUTURE of SCREENS from James Stanton a Little Bit About Me
    THE FUTURE OF SCREENS From james stanton A little bit about me. Hi I am James (Mckenzie) Stanton Thinker / Designer / Engineer / Director / Executive / Artist / Human / Practitioner / Gardner / Builder / and much more... Born in Essex, United Kingdom and survived a few hair raising moments and learnt digital from the ground up. Ok enough of the pleasantries I have been working in the design field since 1999 from the Falmouth School of Art and onwards to the RCA, and many companies. Ok. less about me and more about what I have seen… Today we are going to cover - SCREENS CONCEPTS - DIGITAL TRANSFORMATION - WHY ASSETS LIBRARIES - CODE LIBRARIES - COST EFFECTIVE SOLUTION FOR IMPLEMENTATION I know, I know, I know. That's all good and well, but what does this all mean to a company like mine? We are about to see a massive change in consumer behavior so let's get ready. DIGITAL TRANSFORMATION AS A USP Getting this correct will change your company forever. DIGITAL TRANSFORMATION USP-01 Digital transformation (DT) – the use of technology to radically improve performance or reach of enterprises – is becoming a hot topic for companies across the globe. VERY DIGITAL CHANGING NOT VERY DIGITAL DIGITAL TRANSFORMATION USP-02 Companies face common pressures from customers, employees and competitors to begin or speed up their digital transformation. However they are transforming at different paces with different results. VERY DIGITAL CHANGING NOT VERY DIGITAL DIGITAL TRANSFORMATION USP-03 Successful digital transformation comes not from implementing new technologies but from transforming your organisation to take advantage of the possibilities that new technologies provide.

    Video compression optimized for racing drones Henrik Theolin Computer Science and Engineering, master's level 2018 Luleå University of Technology Department of Computer Science, Electrical and Space Engineering Video compression optimized for racing drones November 10, 2018 Preface To my wife and son always! Without you I'd never try to become smarter. Thanks to my supervisor Staffan Johansson at Neava for providing room, tools and the guidance needed to perform this thesis. To my examiner Rickard Nilsson for helping me focus on the task and reminding me of the time-limit to complete the report. i of ii Video compression optimized for racing drones November 10, 2018 Abstract This thesis is a report on the findings of different video coding tech- niques and their suitability for a low powered lightweight system mounted on a racing drone. Low latency, high consistency and a robust video stream is of the utmost importance. The literature consists of multiple comparisons and reports on the efficiency for the most commonly used video compression algorithms. These reports and findings are mainly not used on a low latency system but are testing in a laboratory environment with settings unusable for a real-time system. The literature that deals with low latency video streaming and network instability shows that only a limited set of each compression algorithms are available to ensure low complexity and no added delay to the coding process. The findings re- sulted in that AVC/H.264 was the most suited compression algorithm and more precise the x264 implementation was the most optimized to be able to perform well on the low powered system.
