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 ...

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 ...

Researchers in Slovakia benchmarked five lossless compression algorithms directly on an STM32 microcontroller, revealing ...

Today the Video Electronics Standards Association (VESA) and the MIPI Alliance announced the finalization and release of the new Display Stream Compression (DSC) Standard version 1.0. DSC is designed ...

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 ...

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 ...
