Bypass bins for reference index coding in video coding

摘要

In an example, aspects of this disclosure relate to a method for decoding a reference index syntax element in a video decoding process that includes decoding at least one bin of a reference index value with a context coding mode of a context-adaptive binary arithmetic coding (CABAC) process. The method also includes decoding, when the reference index value comprises more bins than the at least one bin coded with the context coded mode, at least another bin of the reference index value with a bypass coding mode of the CABAC process, and binarizing the reference index value.

1. A method for encoding a reference picture index syntax element in a video encoding process, the method comprising:
binarizing a reference picture index value; encoding at least one bin of the binarized reference picture index value with a context coding mode of a context-adaptive binary arithmetic coding (CABAC) process; determining that the binarized reference picture index value comprises more bins than the at least one bin coded with the context coded mode; and encoding, in response to determining that the binarized reference picture index value comprises more bins than the at least one bin coded with the context coded mode, at least another bin of the binarized reference picture index value with a bypass coding mode of the CABAC process.
