Blog Essay: H.264 is Magic
« on: November 11, 2016, 10:20:49 AM »
Nice long blog post about a ubiquitous video compression algorithm.

"H.264 is Magic"

Quote
H.264 is a video compression codec standard. It is ubiquitous - internet video, Blu-ray, phones, security cameras, drones, everything. Everything uses H.264 now.

H.264 is a remarkable piece of technology. It is the result of 30+ years of work with one single goal: To reduce the bandwidth required for transmission of full-motion video.

Technically, it is very interesting. This post will give insight into some of the details at a high level - I hope to not bore you too much with the intricacies. Also note that many of the concepts explained here apply to video compression in general, and not just H.264.

Yet easily surpassed in x.265 also known as h.265 also known as HEVC. Picture quality is far better and storage space requirements/streaming requirements are much lower in comparison with h.264.

There is also coming such an improvement coming for audio, mainly the AAC audio codec. HE-AAC has already been in use since digital radio became common. But now there is HEv2-AAC and especially for voice information will benefit as it will take significantly less bandwidth to transfer that data. See here for an introduction.
