los´sy com`pres´sion

(Computers) The compression of binary data into a form which, when it is re-expanded, has most, but not all, of the original information. It is used primarily for compression of images and sounds, and is designed to provide a high degree of compression at the cost of a slight loss of data. It is expemplified by the JPEG compression standard. Images compressed by a lossy compression algorithm are re-expanded into an image close, but not identical to the original image; the difference between the original and the reconstructed image may be imperceptible to normal viewing by the eye.

For all 5.1 formats, the AV receiver must decode the incoming data (lossy encoding as in Dolby Digital for a standard DVD or lossless encoding as used for a DVD-A), add the appropriate time delay to each speaker, perform bass management, equalize the channels, level adjust each channel and, if desired, add in sound-field synthesis.
