MIL-HDBK-9660B
updated platform suitable for delivering enhanced multimedia functionality (e.g., includes MPEG video).
cc. MPEG - A compression standard for full motion, full screen, digital video, designed to deliver
30fps over such limited bandwidth transmissions as CD-ROM applications running on a PC. ISO/IEC
11172:1993 describes the standards for MPEG-1, ISO/IEC 13818:1996 describes the standards for MPEG-2. One minute of MPEG-1 video requires 9 MB of storage space. The MPEG-2 algorithm applies to a higher bit rate and a higher quality than MPEG-1 and is designed for high-bandwidth transmissions such as satellite-based broadcasting. MPEG-2 requires at least a 4X speed CD drive.
dd. Multiread - The ability of a device (to include DVD-ROM players) to read all CD-A, CD- ROM, CD-R, and CD-RW media. The draft implementation guide (version 0.71) defines the full system environment (hardware and firmware requirements) for developing Multiread compatible devices. Multiread is used to switch a disc from the packet written UDF format to and from the ISO 9660 format. It also includes defect management to ensure data can be read after long periods of time.
ee. Multisession - True Orange Book allows for incremental writing of each track on a disc separately and writing individual tracks in multiple sessions. Each session is like a mini-disc because each contains a lead-in, tracks, and a lead-out. Multisession-capable playback devices view multisession discs as one "logical" volume when mounted by the computer's operating system, ignoring all but the last directory. The most popular use of multisession is Photo-CD (Mode 2, Form 1, of the CD- ROM XA format).
ff. Orange Book - This book provides specifications describing the physical attributes associated with CD-Recordables (CD-R). It is divided into two parts: one for CD-MO (Magneto-Optical, rewritable) and one for CD-WO (Write Once). CD-WO identifies track-at-once and incremental writing, using either fixed- or variable-length packets.
gg. Packet Writing (see also Incremental Recording) - Packet writing refers to recording incrementally within a track with multiple data streams (packets), each separated by gaps. A packet- written disc cannot be read by a standard CD-ROM drive until the open track is closed and a session created with lead-in and lead-out blocks. When done, an ISO 9660 file system is created to map the directory to the packets on the disc.
hh. PD - Phase Change Dual Technology - Combines the benefits of high-capacity phase change rewritable (PCR) optical storage (650 MB capacity) with the advantages of high-speed, high performance CD-ROMs (4X speed) in a single drive. Reference ISO/IEC DIS 15485, 120mm ODC Using Phase Change PD form.
ii. Phase Change Rewritable/Rewritability (PCR) - A technique for writing, reading, and direct overwriting to optical discs by changing the molecular structure of the metallic recording layer between crystalline (highly reflective) and amorphous (low reflective) states when pulsed by a laser.
jj. Photo-CD - A proprietary multisession storage format by Kodak & Philips, originally designed to display up to one hundred 35mm slides (estimated at 6 MB each) on a television using a Kodak Digital Science Photo-CD player (which also plays audio CDs), Philips CD-i player, Panasonic/3DO R.E.A.L. player or, in the near future, a Sega Saturn player. Photo-CD discs can also be played on a computer on a multisession CD-ROM XA drive equipped with Photo-CD access software, Apple Computer's
QuickTime extension, the IRIX operating system from Silicon Graphics, or Sun Microsystems' Solaris. IBM's OS/2 Warp platform can also read and write Photo CD discs, and IBM supports Photo-CD technology in its AIX operating system (which runs on RISC System/6000 workstations) through
