Apparatus and method for vector-based entropy coding for display stream compression

Methods and apparatus for coding video information having a plurality of video samples include partitioning samples into groups for transmission within a single clock cycle, wherein the samples are associated with a bit length B, and a group having a group size K. The sample group is mapped to a code number and coded to form a vector-based code comprising a first portion identifying a type of look-up-table used to performing the mapping, and a second portion representing the samples of the group. The look-up-table may be constructed based upon occurrence probabilities of different sample groups. In addition, different types of look-up-tables may be used for different B and K values.
