With the advent of Blu-ray, the additional storage
space has allowed for lossless audio compression
schemes. While the compression ratio is typically
five times lower than lossy compression, lossless
compression allows for the exact reproduction of the
original PCM signal.
Compressed Video
Full-motion video requires a monumental amount
of information to be stored. All digital consumer
formats compress the video signal to allow it to fit
on the disc. Luckily, digital video lends itself well to
compression and both DVD and Blu-ray can provide
superb picture quality using various video
compression schemes.

compression format.
