Spatio-temporal motion vector prediction patterns for video coding

Abstract:

Techniques are described for constructing motion vector predictor lists based on spatially neighboring blocks and collocated blocks. A method of coding video data includes, for a first block, in a first picture having a left-to-right coding order, constructing a first motion vector predictor list, wherein a first entry in the first motion vector predictor list is based on motion vector information of a left neighboring block to the first block, coding the first block in the first picture based on the first motion vector predictor list, for a second block, in a second picture having a right-to-left coding order, constructing a second motion vector predictor list, wherein a first entry in the second motion vector predictor list is based on motion vector information of a right neighboring block to the second block, and coding the second block in the second picture based on the second motion vector predictor list.
