ABSTRACT:
The invention concerns a method (200) and system (100) for generating a dummy bidirectional predictive picture which can be repeated during display with substantially no vibration in which the dummy bidirectional predictive picture contains at least two fields. The method includes the steps of setting (220) a parameter of the dummy bidirectional predictive picture to indicate that no encoding of a residual signal will occur and employing (216, 222, 224) field-based prediction to predict the at least two fields of the dummy bidirectional predictive picture. The setting step can further include setting the parameter of the dummy bidirectional predictive picture to indicate that no discrete cosine transform encoding of the residual signal will occur. The dummy bidirectional predictive picture can include a plurality of macroblocks, and each macroblock can contain at least a portion of the at least two fields and the parameter can be a macroblock parameter.
