Flexible data organization for images

摘要

A system, a method and computer-readable media for encoding image data into a compressed bitstream. A mode selection component is configured to select a mode of operation for use in encoding image data. A spatial mode encoder is utilized when the mode selection component selects a spatial mode of operation. The spatial mode encoder is configured to encode the image data into packets by organizing the image data in accordance with a spatial partitioning. A frequency mode encoder is utilized when the mode selection component selects a frequency mode of operation. The frequency mode encoder is configured to encode the image data into packets by organizing the image data in accordance with a frequency ordering.

1. Computer-storage media storing computer-useable instructions that, when executed, perform a method for encoding image data in a bitstream, the method comprising:
determining whether to encode the image data using a spatial-mode encoding technique or a frequency-mode encoding technique, if the spatial-mode encoding technique is selected, constructing an index table in the header of the bitstream to include a number of tile pointers equal to a number of tiles, and if the frequency-mode encoding technique is selected, constructing the index table in the header of the bitstream to include a number of tile pointers based on a number of bands skipped.
