APPARATUS FOR DECODING MOTION INFORMATION IN MERGE MODE |
摘要 |
Disclosed is an apparatus for decoding motion information in merge mode for reconstructing a moving picture signal coded at a low data rate while maintaining a high quality of an image. The apparatus for decoding motion information in merge mode discloses the position of a merge mode candidate and the configuration of a candidate in order to predict motion information in merge mode efficiently. Furthermore, a merge candidate indicated by the merge index of a current block can be efficiently reconstructed irrespective of a network environment by adaptively generating a merge candidate based on the number of valid merge candidate. |

1. An apparatus for decoding motion information in merge mode, comprising:
a merge mode motion information decoding unit configured to decode motion information using available spatial and temporal merge candidates when a motion information encoding mode of a current block indicates a merge mode; a prediction block generation unit configured to generate a prediction block of the current block using the decoded motion information; and a residual block decoding unit configured to generate a quantization block by inversely scanning residual signals, inversely quantize the quantization block using a quantization parameter, and generate a residual block by inversely transforming the inverse-quantized block, wherein when the current block is not adjacent to a lower boundary of a largest coding unit, a motion vector of a first merge candidate block is determined as a motion vector of the temporal merge candidate if the motion vector of the first merge candidate block is available and a motion vector of a second merge candidate block is determined as the motion vector of the temporal merge candidate if the motion vector of the first merge candidate block is unavailable.
