What is the embedded bit-stream?

Filtering the image through subsequent quality layers creates the embedded bit-stream; the first one (Q0) codifies the different code-blocks by using a prefixed length l0 and minimizing the distortion. The following layers contain additional contributions related to every code-block, minimizing further the distortion. Each quality layer contains the contributions of each code-block. In order to have an embedded bit-stream that allows scalability in distortion, it is necessary to introduce enough information to identify the contributions of each quality layer related to the code-blocks.
