| Keywords: Inter prediction referencing VP8.svg en Schematic representation of an exemplary image sequence showing possible inter-frame referencing relationships in temporal inter prediction in VP8 Predicted frames marked with letter <span style color cc0033; >p</span> can copy motion compensated image data from other frames and code a difference signal to correct this prediction Each predicted frame can use up to three buffered reference frames Its directly preceding frame the last so-called golden frame depicted in <span style color ccc333; >yellow</span> colour and the latest alternate reference altref frame marked with letter <span style color cc0033; >a</span> Altref frames may signal to not get displayed after decoding and only replace the altref buffer content In asynchronous use cases the encoder could look ahead and use an evaluated future frame to construct an altref frame from frames that lie ahead in time Intra frames marked <span style color cc0033; >I</span> don't rely on temporal prediction and hence don't reference any other frame <span style color 33ccff; >Blue</span> arrows signify how image data gets copied over to be used to re- construct another frame 2016-07 own Flugaal other versions cc-zero TrueMotion VPx Technical diagrams Inter-frame prediction | ||||
