Abstract:
A media processing method, comprising:accessing a compressed image data set representing a time series of different compressed video images that have been compressed to differing degrees based on sizes of the compressed video images with a plurality of different quantization tables and including a first compressed video image compressed with a first quantization table and a second video image compressed with a second quantization table, and decompressing the compressed image data set to retrieve the time series of different video images, wherein the step of decompressing the compressed image data set includes a step of decompressing the first compressed video image to obtain a first video image and a step of decompressing the second video image to obtain a second video image, and wherein the step of decompressing is operative independent of information indicating a difference between the first and second quantization tables.
