METHOD FOR MASKING ERRORS IN VIDEO SEQUENCES Russian patent published in 2008 - IPC H04N7/68 G06T9/00 

FIELD: video data encoding, in particular, masking of distortions introduced by errors.

SUBSTANCE: method and device are claimed which are meant for masking errors in video sequences. When a transition between scenes exists in a video sequence and an error is present in the image which is subject to transition between scenes, error masking procedure is used, which is based on type of transition between scenes, to conceal the error. Information about transition between scenes together with information about the type of transition between scenes is transferred to video decoder in the message of additional extension information, if the transition between the scenes represents a gradual transition between the scenes, algorithm of spatial-temporal masking of errors is used for masking the image, if the transition between the scenes represents a scene cut, and only a part of the image is lost or damaged, then spatial error masking is used to mask the lost or damaged part of the image, and if the whole image belonging to scene cut is lost or damaged, and the image begins a new scene, it is not masked.

EFFECT: creation of method, by means of which the appropriate form of error masking may be selected for frames which are subject to transitions between scenes in a video series.
