Limited motion vector information derived from motion vectors on one side of decoder

摘要

It describes the techniques related to the derivation of the moving vector on one side of the decoder. For example, this description describes techniques related to imposing one or more restrictions on mobile information, such as differences between a dmvd derived mobile vector (MV) and / or a dmvd derived MV. If restrictions apply to dmvd, in some cases only derived flow information that meets the restrictions is considered valid flow information. Conditions can be placed in constraints.
