15. A computer program product comprising at least one non-transitory computer-readable storage medium having computer-executable program code instructions stored therein, the computer-executable program code instructions comprising program code instructions to: determine a frequency of occurrence threshold based on an expected frequency of occurrence of syntax elements in a bit stream; categorize a plurality of syntax elements of video content into first and second categories based on the frequency of occurrence threshold, wherein syntax elements which occur greater than the frequency of occurrence threshold are categorized into the first category and syntax elements which occur less than the frequency of occurrence are categorized into the second category; entropy code symbols that correspond to the first category of syntax elements and that have been subjected to a context update; and entropy code symbols that correspond to the second category of syntax elements and that have bypassed context updating.
17. A computer program product according to claim 15 wherein the computer-executable program code instructions further comprise program code instructions to perform binarization of the symbols that correspond to the second category of syntax elements prior to bypassing the context updating.
