Quantization table adjustment

摘要

The application discloses a media processing method that includes accessing a compressed image data set representing a time series of different compressed video images. These video images have been compressed to differing degrees based on sizes of the compressed video images with a plurality of different quantization tables. The compressed image data set can then be decompressed to retrieve the time series of different video images, and this step of decompressing can be operative independent of information indicating a difference between quantization tables used to compress the images.
