Regards, Henning -------------------------------------------------------------------------- #include | henning@kather.enet.dec.com -------------------------------------------------------------------------- ------------------------------------ DEC CDpublish for MS-DOS and Windows DEC CDpublish for ULTRIX and OSF/1 ------------------------------------ Following the great success of the Compact Disc (CD) as storage medium for high quality audio, CD-ROM has now become a globally established storage medium for digital data. Offering a combination of high capacity (640 MB), high data reliability, compact size and low cost (for both discs and drives), it is a new medium for storage and distribution of large volumes of information, such as encyclopaedias, databases, optical images or technical documentation. International standards for CD-ROM were established when this technology was first introduced, and these ensure that any CD-ROM is compatible with the drives of the various manufacturers. DEC CDpublish lets you produce CD-ROMs formatted according to ISO9660 and Bridge Disc standards. The contents of any files on your hard disk can be copied using a special CD-recording device to a recordable CD, the so-called 'CD-Recordable' (CD-R) or better 'CD-Write Once' (CD-WO). This disc may subsequently be read in CD-ROM drives. Independent Usage ----------------- Until now, to produce a CD you needed to have a CD manufacturing company create a master CD and successively produce copies of this. This process is time-consuming and, particularly in the case of a small number of copies, leads to a high cost for each final copy. With DEC CDpublish you create each CD right at your desktop, without any need for external facilities, as easiliy as copying data to a floppy disk. A Variety of Applications ------------------------- Whenever large amounts of data have to be archived or distributed, whether internally within the company or to customers, DEC CDpublish provides an ideal alternative to employing paper, magnetic tape or diskettes. Whether your data comprises manuals or databases, internal standards or policies documentation, collections of digital images or huge information retrieval applications, DEC CDpublish always provides you with the advances of CD technology: o large storage capacity in combination with high data reliability o selection of data by computer search o text, images, data immediately accessible on the CD-ROM for copying and further processing. Sources of Data --------------- The data to be written to the CD may be retrieved from hard disk or via LAN, from floppy disk or CD-ROMs. It is even possible to use the data which is already on the current CD- Recordable. Update of Information --------------------- A particular advantage of DEC CDpublish is its ability to fill the free space left on a CD, after data has been written, by writing additional portions of data, so-called 'sessions'. Thus the complete storage space of a CD can actually be made use of. Conventional CD-ROM drives may only access the first session of a CD, while the recent generation of 'multi-session CD-ROM drives' provide access to the most recent session. The the CD- Recorder can read any session on CD. DEC CDpublish for MS-DOS ------------------------ The first member of the family of DEC CDpublish products is the version running on MS-DOS. Like all DEC CDpublish products this lets you write CD-Recordables according to the ISO9660 standard. Such CDs can be read by any conventional CD-ROM drive. Alternatively you may write the data to the CD-Recordable in Bridge-Disc format, which provides you with the opportunity to create several sessions. A CD-ROM drive with multi-session capability accesses the most recent session on CD, while a CD- Recorder itself can read any session. DEC CDpublish for Windows ------------------------- DEC CDpublish for Windows is the enhancement of the DOS version for Windows 3.1. Besides the intuitive and easy-to-use graphical user interface this version offers several extensions: Adding and updating of information is done with increased efficiency of storage use. This is accomplished by writing only that data which has been changed or newly added. As a Bridge- Disc the final result is readable in any multi-session CD-ROM drive. When using the CD-Recorder you may even access any intermediate state of those updates. In addition you may record digital audio tracks to produce pure audio CDs or mixed mode CD-ROMs. Also you can produce CD-I and CD-ROM/XA discs from pre-formatted images. PC Configuration ---------------- The product delivery contains a CD-Recorder Philips CDD 521/10 to be connected to a PC-386/486 by means of the enclosed SCSI adapter (16-Bit PC/AT slot card).The publishing software has to be installed on the hard disk of the PC. The minimum hardware requirements are moderate: to use the DOS version 1 MB RAM suffices; the access time of the hard disk has to be less than 19 ms, while its size must be large enough for your requirements. DEC CDpublish for ULTRIX ------------------------ The DEC CDpublish version for ULTRIX comprises the functionality of DEC CDpublish for MS-DOS plus UNIX specific extensions. These extensions include taking care of the naming conventions applying to UNIX files and allow deeply nested directory trees to be transferred to CD whilst still conforming to the ISO9660 standard. DEC CDpublish for OSF/1 ----------------------- Compared with the ULTRIX version DEC CDpublish for OSF/1 goes a step further in supporting the 'RockRidge Interchange Protocol'. Discs generated in this way are compatible with ISO9660, but implement all POSIX file system attributes by format extensions according to RockRidge. Mounting such a CD in a RockRidge compatible platform delivers the original UNIX file system transparently to applications. Workstation Configuration ------------------------- The product delivery for ULTRIX contains a Philips CDD521/10 CD-recorder, which needs exclusive connection to a SCSI- controller (PMAZ-AB). The DECstation where CDpublish for ULTRIX is installed requires a 650 MByte harddisk partition for the CD-image generated as part of the recording process. ULTRIX Version 4.3 with ISO9660 File System and SCSI/CAM software is assumed. DEC CDpublish for OSF/1 installs on an Alpha AXP System with OSF/1 V2.0. As an alternative to the Philips CD-recorder, the Yamaha CDR100 (E) is supported.
