SPACE-TIME PREDICTION FOR BI-DIRECTIONAL PREDICTABLE (B) IMAGES AND METHOD FOR PREDICTION OF MOVEMENT VECTOR TO COMPENSATE MOVEMENT OF MULTIPLE IMAGES BY MEANS OF A STANDARD

摘要

FIELD: video encoding, in particular, methods and devices for ensuring improved encoding and/or prediction methods related to various types of video data.;SUBSTANCE: the method is claimed for usage during encoding of video data in video encoder, containing realization of solution for predicting space/time movement vector for at least one direct mode macro-block in B-image, and signaling of information of space/time movement vector prediction solution for at least one direct mode macro-block in the header, which includes header information for a set of macro-blocks in B-image, where signaling of aforementioned information of space/time movement vector prediction solution in the header transfers a space/time movement vector prediction solution into video decoder for at least one direct mode macro-block in B-image.;EFFECT: creation of improved encoding method, which is capable of supporting newest models and usage modes of bi-directional predictable (B) images in a series of video data with usage of spatial prediction or time distance.;2 cl, 17 dwg
