1. A method comprising:
determining, by a computing device and based on a total quantity of symbols predicted for both a first magnitude component and a second magnitude component of a block vector difference (BVD) associated with decoding of a current block of content, a quantity of symbols predicted for the first magnitude component of the BVD;
entropy decoding, based on the quantity of symbols predicted for the first magnitude component, an indication of whether a value of a most significant symbol of the first magnitude component of the BVD matches a value of a most significant symbol of a first magnitude component of a BVD predictor associated with the current block;
determining, based on the value of the most significant symbol of the first magnitude component of the BVD predictor and the indication, the value of the most significant symbol of the first magnitude component of the BVD; and
decoding, based on the BVD, the current block.
