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 ...

Coding, information theory and compression provide a unified framework for quantifying, transmitting and summarising data. At its heart lies the concept of entropy, which measures the average ...

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 ...

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 ...

Google is open-sourcing a new general purpose data compression library called Zopfli that can be used to speed up Web downloads. The Zopfli Compression Algorithm, which got its name from a Swiss bread ...

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 ...
