A variable bit rate encoding method for JPEG 2000 is presented. All bit rate constraints described in the DCI Digital Cinema System Specification are satisfied. At the same time, average quality is maximized as allowed by these constraints. Additionally, rate allocation for extra quality (bit rate) layers is discussed. Extra quality layers may have applications in archiving and may provide a method for backward-compatible bit rate enhancements.
