VDA sekilas
VDA
The Truevision line grew out of EPICenter-era PC graphics boards, and several board names ended up surviving as filename extensions even when the underlying raster structure stayed close to the wider TGA family.
NCX sekilas
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.
