Abstract
Official abstract text for this publication.
Provided are methods and apparatuses for encoding and decoding a motion vector. The method of encoding a motion vector includes: selecting a mode from among a first mode in which information indicating a motion vector predictor of at least one motion vector predictor is encoded and a second mode in which information indicating generation of a motion vector predictor based on pixels included in a previously encoded area adjacent to a current block is encoded; determining a motion vector predictor of the current block according to the selected mode and encoding information about the motion vector predictor of the current block; and encoding a difference vector between a motion vector of the current block and the motion vector predictor of the current block.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for encoding a motion vector, the apparatus comprising: a predictor which obtains motion vector predictor candidates of a current block using a block co-located with the current block in a temporal reference picture in direction List0 or List1 when the prediction mode of the current block is inter-prediction, and obtains a motion vector predictor of the current block among the obtained motion vector predictor candidates; a first encoder which…
