- Description
- CD-ROM XA (Compact Disc - read-only-memory, extended architecture) is a modification of CD-ROM that defines sectors that enable it to read and display data, graphics, video, and audio. Photo CD, Video CD, CD-EXTRA and Super Video CD have all been based on CDXA and it may be possible to further distinguish between these different CDXA variant formats with further PRONOM research.
