Most of us deal with data compression on a daily basis, but what is it and how does it work? Professor David Brailsford introduces compression with regards to text and pictures.

    Without compression this video would be 1920pixel*1080pixel*24bit depth*25fps*(7*60+38)seconds = 569825280000bit = 71.23GB big.

    I love any 45+ computer science professionals/lecturers, they have a very calm way of explaining ideas :)

    I came up with the dumbest idea for my friend and I to develop, a lossy alternative to .zip and .rar. Just imagine all the affects you could get.

    You've gotta go tip-to-tip for optimal efficiency - use the middle-out!

    Great explanation. It's basically like factoring out an equation. All about efficient use of space

    How kind and helpful of you. Good thing you're around, otherwise people might think it's okay to ask questions.

    I hope Computerphile also discusses fractal compression (and fractal interpolation) because the concepts are so frikkin' cool. BTW, the key signatures in standard music notation can also be thought of as a compression scheme. Thanks for the great stuff, Brady!

    The channel is definitely getting closer to what I was expecting and it's nice to see after being so terrified of the first video! Very much looking forward to see a little more advanced topics. :)
