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 ...

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 ...

Finding efficient ways to compress and decompress data is more important than ever. Compressed data takes up less space and requires less time and network bandwidth to transfer. In cloud service code, ...

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 ...

Data compression is critical to cloud and data streaming applications by reducing data transfer times and storage utilization. But compressing and decompressing data ...

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 ...

Digital video currently follows the MPEG-2 standard, but improvements in image processing technology are set to move MPEG-4 to the forefront of video compression. Millions of DVD disks, satellite ...

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.

Digital video and audio coding technology has a long research history and international standards have also been established. It can be said that all of the effort involved with this finally ...
