Abstract

Disclosed are a method and apparatus for determining a context model for transform coefficient entropy encoding and decoding. In the method and apparatus for determining a context model a context set index (ctxset) is acquired on the basis of color component information in transform units the current subset position and whether or not a valid transform coefficient having a value greater than a first critical value exists in the preceding subset and a context offset (c1) is acquired on the basis of the length of a preceding continuous transform coefficient having a value of 1. Also a context index (ctxidx) is determined for entropy encoding and decoding of a first critical value flag on the basis of the acquired context set index and the context offset.
