MP4 in sintesi
MP4
MP4 grew out of the MPEG-4 and ISO Base Media File Format lineage, which helped make it both standards-based and commercially pervasive.
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.
