Method and arrangement for video coding

Encoder (E1-E8) for encoding at least one video stream (IV1,1V2), said encoder including at least one input terminal (IN1,1N2) for receiving said at least one input video stream (IV1,1V2), said encoder being further adapted to construct a sequence of predicted pixel blocks (PPB1, PPB2), to process said sequence of predicted pixel blocks (PPB1, PPB2) and corresponding blocks of said at least one input video stream (IV1,IV2) to thereby obtain a sequence of processed residual pixel data (QPRD1, QPRD2),

• wherein said encoder further includes an additional input terminal (INRef) for receiving reference input data (IREF) , and wherein said encoder is further adapted to construct said sequence of predicted pixel blocks (PPB1, PPB2) from input encoding structure data (IESD) from said reference input data (IREF) and to entropy encode said reference input data (IREF) in combination with said processed residual pixel data (QPRD1, QPRD2) to thereby generate at least one encoded video stream (EV1, EV2) for provision to at least one output terminal (OUT1, OUT2) of said encoder.
