Digital video coding integrates algorithmic techniques and standardised frameworks to reduce the volume of raw pixel data while preserving perceived visual quality. Most contemporary systems employ a ...

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 ...

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 ...

Lossless data compression of digital audio signals is useful when it is necessary to minimize the storage space or transmission bandwidth of audio data while still maintaining archival quality.
