Abstract
Two encoders are used in cascade wherein one encoder functions as a preprocessor for the other by collecting statistics concerning partially processed input data. The statistics thus derived are autonomously transferred to a second decoder in a self-synchronized manner, avoiding any need for external glue logic, and utilized to select encoding options for encoding and/or compressing the data so that the quality of encoded data is optimized based on the content of current input data.
