Abstract
Like type bits are grouped into continuous runs and thus are modeled and processed as a group. This allows entire groups of bits to be skipped by coding passes to which the coefficients do not belong. Furthermore, by using the context of a bit by looking at the significant state of its neighbors, and storing them in a specific order, bit-wise operations and memory accesses can be reduced.
Claims11
A method of modeling coefficients comprising:
- analyzing a group of coefficients;
- determining if the coefficients can be modeled as a group;
- and
- modeling and encoding the coefficients as a group, thereby allowing the group to be skipped by one or more specific coding passes if the group does not belong to that specific coding pass.

A system that models coefficients comprising:
- a group modeling module that analyzes a group of coefficients and determines if the coefficients can be modeled as a group;
- and
- a coding module that cooperates with the group modeling module to model and encode the coefficients as a group, thereby allowing the group to be skipped by one or more specific coding passes if the group does not belong to that specific coding pass.
A system for modeling coefficients comprising:
- means for analyzing a group of coefficients;
- means for determining if the coefficients can be modeled as a group;
- and
- means for modeling and encoding the coefficients as a group, thereby allowing the group to be skipped by one or more specific coding passes if the group does not belong to that specific coding pass.

An information storage media comprising information that models coefficients comprising:
- information that analyzes a group of coefficients;
- information that determines if the coefficients can be modeled as a group;
- and
- information that models and encodes the coefficients as a group, thereby allowing the group to be skipped by one or more specific coding passes if the group does not belong to that specific coding pass.
