LOSSLESS-CODING-MODE VIDEO ENCODING METHOD AND DEVICE, AND DECODING METHOD AND DEVICE |
| 摘要 |
Provided is an encoding method for encoding a last position of a significant transformation coefficient in lossless coding, according to an exemplary embodiment, the encoding method including: performing scanning from a first point to a second point of a coding unit in a predetermined order to obtain a transformation coefficient included in the coding unit; determining a last position of a significant transformation coefficient that is not 0 from among transformation coefficients included in the coding unit; determining position information corresponding to the determined last position with respect to the second point; and encoding the determined position information. |
