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 7):
The video decoding apparatus of  claim 6 , wherein the entropy decoder is configured to convert the first quantization parameter into the second quantization parameter based on: QP O = \ue89e QP I + 6 \u00d7 ( BD O - BD I ) \ue89e \ue89e ( QP \ue89e \ue89e 1 + 6 \u00d7 ( BD O - BD I ) \u2265 0 ) = \ue89e QP \ue89e \ue89e 1 \ue89e \ue89e ( QP I + 6 \u00d7 ( BD O - BD I ) < 0 ) , where QP I  and QP O  are the first quantization parameter and the second quantization parameter of the bitstream, respectively, and BD I  and BD O  are the bit depth of the bitstream and the reference bit depth, respectively.
