Abstract:
A video decoding apparatus, a computing system including the same, and a video decoding method. The video decoding apparatus may include an entropy decoder and a video decoder. The entropy decoder may be configured to obtain encoding information of a bitstream of an encoded video from a header of the bitstream, the encoding information of the bitstream including a bit depth of the bitstream, and convert a first quantization parameter of the bitstream into a second quantization parameter when the bit depth of the bitstream is different from a reference bit depth. The video decoder may be configured to decode the bitstream based on the second quantization parameter.

Claim (Index 10):
A video decoding apparatus comprising:\n an entropy decoder configured to,\n obtain encoding information of a bitstream of an encoded video from a header of the bitstream, the encoding information including a bit depth of the bitstream, and \n convert a first quantization parameter of the bitstream into a second quantization parameter when the bit depth of the bitstream is greater than a reference bit depth; \n an adder configured to generate data of a spatial domain based on residue data, the residue data being restored using a quantization step size and data intra-predicted or inter-predicted from the bitstream, the quantization step size corresponding to the second quantization parameter when the bit depth of the bitstream is greater than the reference bit depth; and a sample adaptive offset (SAO) filter configured to generate a video output by performing SAO filtering on the data of the spatial domain based on the second quantization parameter and a decoding offset.
