T22 - Go on! Surprise Me! An introduction to Audio and Video Coding
Jamie Angus (Presenter) Coded Audio is an essential part of modern audio distribution, such as the internet, film, etc. But how does it work? What is it about a signal that can allow you to reduce its data rate without loss, as in “Lossless Coding”? How can one take advantage of human perception when one does lossy coding such as mpeg? This tutorial will use both video and audio coding to explain the characteristics that allow one to encode such signals at a reduced data rate without any loss of fidelity. It will then go on to explain how one can go about reducing the data rate with the minimum of perceptible distortion.
