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 ...

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 ...

Artificial intelligence (AI) can be successfully applied to images and videos to improve how they look - to add colour, to understand their content better or to help with storytelling, for instance.

We are currently researching a video and audio coding technologies for advanced terrestrial broadcasting. Here, we present a real-time versatile video coding (VVC *) decoder that supports multilayer ...

An ordinance from the Ministry of Internal Affairs and Communications (MIC) was issued in 2011 on revision of the audio coding formats of 8K Super Hi-Vision (8K) broadcasting using 22.2 multichannel ...

When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. At long last, HDTV is arriving in Europe, with a single HDTV DBS service already operating, and ...

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.
