 In this process, each \ac{ctu} is partitioned to form a quadtree structure of \ac{ecu} that are used to test the different \ac{ec} candidate modes.
 Then, the best trade-off between \ac{ecu} partition and signalling is found through \ac{rd} optimisation.
 In order to achieve an efficient use of the signalling overhead a saliency-weighted procedure is embedded in the \ac{rd} optimisation based on a spatio-temporal saliency, where more signalling bits are allocated to regions with higher saliency values.
-Finally, the signalling information is transmitted to the decoder by using the \ac{sei} \ac{nal} unit type~\cite{HEVCHighLevelReferenceDez2012}.
+Finally, the signalling information is transmitted to the decoder by using the \ac{sei} \ac{nalu} type~\cite{HEVCHighLevelReferenceDez2012}.
 Since in general, the optimal \ac{ec} mode is still not be able to correctly reconstruct all the missing regions, extra residual information is multiplexed in the stream as a scalable \ac{el}.
 This residual information contains the difference between the compressed ($\hat f_t$) and the \ac{ec} frames ($\tilde f$).

 The additional residue received from the enhancement layer is particularly useful to improve the quality of those \acs{ctu} where the \ac{ec} strategies are  not able to produce very accurate reconstruction.
 Moreover, since the enhancement layer only carries residual information the overhead is affordable.

-Note that the generated bitstream is compliant with the standard, as the error concealment signalling is encapsulated in  \ac{sei} \acs{nal} units (NALU) while the error concealment residue is carried in NALUs related with the scalable extension. Then, an adapted decoder, capable of decoding both the \ac{sei} NALUs and the scalable NALUs takes full benefit from the proposed method. Nevertheless, any standard \ac{hevc} decoder is also able to reconstruct the video, because it simply ignores the extra NALUs.
