1 Scope
This document defines the syntax and an accompanying decompression process that is
capable to represent continuous-tone grey-scale, or continuous-tone colour digital
images without visual loss at moderate compression rates. Typical compression rates
are between 2:1 and 6:1 but can also be higher depending on the nature of the image.
In particular, the syntax and the decoding process specified in this document allow
lightweight encoder and decoder implementations that limit the end-to-end latency
to a fraction of the frame size. However, the definition of transmission channel buffer
models necessary to ensure such latency is beyond the scope of this document.
This document:
-
— specifies decoding processes for converting compressed image data to reconstructed
image data;
-
— specifies a codestream syntax containing information for interpreting the compressed
image data;
-
— provides guidance on encoding processes for converting source image data to compressed
image data.
