Claim 3:
4. A non-transitory computer-readable medium for recording a bitstream, the bitstream comprising:
a bit string with respect to a syntax element,
wherein the bit string is obtained by:
generating a symbol indicating the syntax element by encoding a video;
obtaining a 10-bit initial value of a context model for at least one bin of the symbol;
determining, based on the 10-bit initial value, slope size information, slope sign information, offset size information, and offset sign information of the context model;
determining an initial probability of the context model, based on the slope size information, the slope sign information, the offset size information, the offset sign information, and a quantization parameter;
performing context adaptive binary arithmetic coding (CABAC) encoding based on the initial probability of the context model; and
generating the bitstream comprising the bit string with respect to the syntax element based on a result of the CABAC encoding,
wherein the slope size information is determined using three bits from the 10-bit initial value,
wherein the slope sign information is determined using one bit from the 10-bit initial value,
wherein the offset size information is determined using five bits from the 10-bit initial value, and
wherein the offset sign information is determined using one bit from the 10-bit initial value.
