Abstract
This disclosure proposes various techniques for limiting the number of bins that are coded using an adaptive context model with context adaptive binary arithmetic coding (CABAC). In particular, this disclosure proposes to limit the number of bins that use CABAC for coding level information of transform coefficients in a video coding process.
