VIDEO ENCODING METHOD WITH BIT DEPTH ADJUSTMENT FOR FIXED-POINT CONVERSION AND APPARATUS THEREFOR, AND VIDEO DECODING METHOD AND APARATUS THEREFOR |
摘要 |
[Abstract] Disclosed are a video encoding method which adjusts the range of output data, which has been encoded so that the bit depth can be controlled during the decoding process of encoded samples, and a video decoding method, which prevents overflow of output data in each step of the decoding process. The video decoding method comprises: decoding by parsing quantized conversion factors for each block in an image from a received bitstream; decoding conversion factors which are less than or equal to a first bit depth by executing an inversion quantization of the quantized conversion factors; and decoding samples which are less than or equal to a second bit depth by executing a first level quantization and inverse scaling of the conversion factors. |
