Coding, information theory and compression constitute the backbone of modern digital communications and data storage. Grounded in Shannon’s seminal work, information theory quantifies the ...

In MPEG Layer III coding the compression gain is mainly achieved through the unequal distribution of energy in the different frequency bands, the use of the psychoacoustic model, and Huffman coding.

Fraunhofer HHI, the institute that has created many of the world's most popular audio/video coding and compression standards, has finalized the next standard for video: H.266, AKA Versatile Video ...

Let's take a look at how the various encodes perform. Throughout the following section, all encodes were made using Handbrake with the settings as mentioned, with the exception of the Nvidia encodes, ...

When Jarek Duda invented an important new compression technique called asymmetric numeral systems (ANS) a few years ago, he wanted to make sure it would be available for anyone to use. So instead of ...

A family of digital audio encoding technologies from Dolby used in movie theaters, home theaters and video games. Introduced in the movie "Batman Returns" in 1992, Dolby Digital has been the most ...

Lossy compression schemes can be based on a source model, as in the case of speech compression, or a user or sink model, as is somewhat the case in image compression. In this chapter we look at audio ...

For years, H.264 has been the go-to video compression standard. Whenever you download a film or TV show, watch a Blu-ray, view HDTV broadcasts, or stream something from various sites and services, ...
