    Abstract: A technique is described for compressing textures for use in a graphics application, such as a 3D game application. The technique includes parsing first-compressed texture information (e.g., S3TC texture information) into respective components of the first-compressed texture information (such as main color information, color index information, main alpha information, and alpha index information). The technique then further compresses the respective components to yield second-compressed texture information (referred to as modified compressed texture information or MCT texture information). The MCT texture information can be stored and then decoded to reconstruct the original S3TC texture information for use in the graphics application. Compared to the use of unmodified S3TC texture information, the technique allows more economical storage of texture information, as well as more efficient loading of the texture information from storage to memory.

    Abstract: The present invention provides an entropy coding method for coding video prediction residual coefficients, comprising the steps of: firstly, zig-zag scanning coefficients of blocks to be coded to form a sequence of (level, run) pairs; secondly, selecting a type of code table for coding a current image block to be coded according to a type of macro block; then switching and coding each (level, run) pair in the obtained sequence of (level, run) pairs with multiple tables, with the reverse zig-zag scanning order for the coding order of the pairs; at last, coding a flag of End of Block EOB with the current code table. The present invention of an entropy coding method for coding video prediction residual coefficients fully considers the context information and the rules of symbol's conditional probability distribution by designing different tables for different block types and different regions of level. The coding efficiency is improved and no impact to computational implementation complexity is involved.
