Generating a dummy bidirectional predictive field picture

Abstract

The invention concerns a method and system for generating a dummy bidirectional predictive (dummy B) field picture. The method includes the steps of setting at least a portion of a first indicator of the dummy B field picture to indicate that no encoding of a residual signal will occur and setting at least a portion of a second indicator of the dummy B field picture to indicate that the dummy B field picture will be predicted from at least one field among a first field and a last field of a reference picture to control a vibration artifact. The dummy B field picture can be a forward or a backward predicted field picture, and the at least one field from which the dummy B field picture is predicted can be a first or last field of the reference picture.
