AVIF in sintesi
AVIF
AVIF emerged from the Alliance for Open Media's work around AV1 and uses the HEIF family as its structural container, which connects it to both modern web delivery and newer image-container design.
NCX in sintesi
NCX
NCX was defined in the 2005 DAISY and ANSI-NISO talking-book standard, then carried forward into EPUB 2 and later treated as a legacy compatibility feature once EPUB 3 introduced XHTML navigation documents.
