METHOD AND APPARATUS FOR ENCODER ASSISTED FRAME RATE UP CONVERSION (EA-FRUC) FOR VIDEO COMPRESSION Russian patent published in 2009 - IPC H04N7/46 G06T7/20 

FIELD: physics; image processing.

SUBSTANCE: invention relates to compressing digital video and specifically to encoder assisted frame rate up conversion (EA-FRUC) for video compression. Proposed is an encoder assisted frame rate up conversion (EA-FRUC) system which utilises video coding and pre-processing operations in the video encoder to use FRUC processing that will occur in the decoder. Processing stages involve determining whether to encode frames in a sequence of frames of video content by determining a spatial activity in a frame of the sequence of frames; determining temporal activity in the frame; determining a spatial-temporal activity in the frame based on the determined spatial activity and the determined temporal activity; determining level of a redundancy in the source frame based on at least one determined activity from the determined spatial activity, determined temporal activity and determined spatial-temporal activity; and encoding the non-redundant information in the frame if the determined redundancy lies within predetermined thresholds.

EFFECT: high quality of interpolated frames in a decoder when narrowing frequency bandwidth, necessary for transmitting information for interpolation, as well as reduced amount of calculations.
