16.3 MPEG Audio Coding We begin with the three separate, stand-alone audio compression strategies that are used in MPEG-1 and MPEG-2 and known as Layer I, Layer II, and Layer III. The Layer III audio ...

High Efficiency Video Coding (HEVC), also known as H.265, promises twice the compression possible with Blu-ray’s best video compression methods. But how does it work, and is it enough to get us ...

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 ...

Recently, DIRECTV announced it would begin using MPEG-4 AVC (H.264) along with new satellite coding to support the expansion of its DBS offerings. In fact, the advanced video compression and satellite ...

Efficient compression using the correlation between HD video for mobile use and 4K video for home use allows for approximately 20% more efficient compression than if they were compressed separately.

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 ...

On the show, the inner workings of the code are a secret coveted by fictional startup Pied Piper's competitors. But in real life, Google is giving away its new compression technology for free.

Using all these savings, the compression ratio in Layer II coding can be increase from 4:1 to 8:1 or 6:1. The frame structure for the Layer II coder can be seen in Figure 16.6. The only real ...
