1. A method comprising:
receiving encoded bits;
decoding a first context-encoded element from the encoded bits, the first context-encoded element related to an absolute value of a first significant transform coefficient in a block;
following the decoding of the first context-encoded element, decoding a second context-encoded element from the encoded bits, the second context-encoded element related to an absolute value of a second significant transform coefficient in the block;
following the decoding of the second context-encoded element, decoding a first bypass-encoded element from the encoded bits using a bypass mode, the first bypass-encoded element related to a sign of the first significant transform coefficient in the block; and
following the decoding of the first bypass-encoded element, decoding a second bypass-encoded element from the encoded bits using the bypass mode, the second bypass-encoded element related to a sign of the second significant transform coefficient in the block.
