Hybrid AI Video Codecs and Modern Streaming Techniques

25 January 2025 at 00:33
Introduction AI and Hybrid Codecs Modern Video codecs are all based on similar principles. Recently, these have been complemented by AI techniques, such as super-resolution, to form hybrid codecs. The current state of the art is one of transition to have one based only on AI eventually: https://deeprender.ai/ Codecs using only AI are several years...

Why Division by Zero Is Impossible: 10 Mathematical Reasons

11 January 2024 at 16:41
A division by zero is primarily an algebraic question. The reasoning therefore follows the indirect pattern of most algebraic proofs: What if it was allowed? Then we would get a contradiction, and a contradiction is the greatest enemy of mathematical rigor. Many students tried to find a way to divide by zero once in their...

Modern DACs, Dither, DXD & High-Res Audio Explained

12 December 2023 at 01:08
Introduction First, we need some background in Digital Signals. This can be mathematically quite advanced, but since I would like this article to be accessible to as wide an audience as possible, here is a link that explains what is needed (not even Calculus is required): https://brianmcfee.net/dstbook-site/content/intro.html Shannon’s Sampling Theorem An important point not emphasized...
