MPEG-4 SLS (Scalable to Lossless Standard)

With its lossless encoding techniques, high fidelity of CD recording is further compressed for archival and playback. Added with its unique and efficient scalable to lossless coding, only a single lossless, compressed SLS bit-stream is maintained, whereby it can be further ‘squeezed’ or ‘reduced’ to match lower bandwidth or storage constrains.
