Abstract

A method for decoding an encoded video signal representing a sequence of pictures, the method comprising: - determining that a corresponding area of a default reference picture, for use in forming a motion compensated prediction for an area of a current picture, has been corrupted or lost; - examining an indicator provided in the encoded video signal to identify an area of an alternative reference picture that is sufficiently similar to the corresponding area of the default reference picture; and - forming a motion compensated prediction for the area of the current picture using the identified sufficiently similar area of the alternative reference picture.
