Abstract
At the 28th Meeting of JVET, it was agreed that there can be several NNPFA SEI messages present for the same picture, for example, when the post-processing filters are meant for different purposes. It is asserted that it would be beneficial to enable signaling of the preferred processing order, as determined by the encoder (i.e., the content producer), for different neural-network post-filters when multiple neural-network post-filters are present. This contribution proposes to add syntax elements to the NNPFC SEI message to enable signalling of preferred processing order.
