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 ...

The Layer II coder provides a higher compression rate by making some relatively minor modifications to the Layer I coding scheme. These modifications include how the samples are grouped together, 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 ...

JPEG coding library, Jpegli. Jpegli has been enhanced while maintaining high backward compatibility, and is said to have improved compression rates by 35% at high-quality compression settings. 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.

The new Versatile Video Coding (VVC) standard advances the state of the art of video compression and has unprecedented application versatility. It has the flexibility to enable emerging applications ...
