-Each output sample is equal to the sum of a sample of the first input image item shifted to the left by 8 bits and of a sample of the second input image item. This can be viewed as a bit depth extension of the first input image item by the second input image item. The first input image item contains the 8 most significant bits and the second input image item contains the 8 least significant bits of the output reconstructed image item which has a bit depth of 16, something that is impossible to achieve with a single [=AV1 image item=].

 NOTE: If the first input image item is the [=primary image item=] and is enclosed in an <code>'[=altr=]'</code> group (see [[#altr-group]]) with the [=Sample Transform Derived Image Item=], the first input image item is also a backward-compatible 8-bit regular coded image item that can be used by readers that do not support [=Sample Transform Derived Image Items=] or do not need extra precision.
 
 NOTE: The second input image item can be marked as [=hidden image item|hidden=] to prevent readers from surfacing it to users.
 
-NOTE: The second input image item loses its meaning of least significant part if any of the most significant bits changes, so the first input image item has to be losslessly encoded. The second input image item supports reasonable loss during encoding.

 NOTE: This pattern can be used for reconstructed bit depths beyond 16 by combining more than two input image items or with various input bit depth configurations and operations.
