2 CD-DA

CD-DA

The digital audio CD (CD-DA) was developed by Sony and Philips following development of the laser videodisc. The standard was defined in 1982 as the “Red Book” standard. It was an immediate consumer success.

3 CD-DA

CD-DA

CDs are 12 cm (4.72 in) in diameter (compared to 12 inches for videodiscs). Audio CDs hold up to 72 minutes of 16 bit audio sampled at 44.1 KHz.

4 CD-ROM

CD-ROM

Sony and Philips developed the CD-ROM as an offshoot of the audio CD. The original standard was defined in 1983-84 with the release of the “Yellow Book” standards. CD-ROM XA extended the standard format, interleaving audio and video, to better support multimedia.

5 CD-ROM

CD-ROM

CD-ROMs hold up to 650 MB of data. Error correction limits errors to 1 in 10 trillion. Because they were designed as a mass storage medium for computers, CD-ROMs made for one computer platform often do not work on a different platform.

6 CD-ROM

CD-ROM

The original standards did not take into account the file system. High Sierra was the first effort to standardize file formats. It uses mainly the old MS-DOS format. HFS supports Apple file names, Rock Ridge supports UNIX, Joliet supports Windows long file names.

7 Recordable CD-ROMs

Recordable CD-ROMs

Recordable CD formats were defined by the “Orange Book” standards. Today, CD-R and CD-RW drives are commonplace, and media costs have declined sharply.

8 Other CD Formats

Other CD Formats

CD Extra (Blue Book) – Audio CD with visual add-ons. CD-I (Green Book) – now defunct multimedia CD format Photo CD – Kodak’s format for storing photos on CD Video CD (White Book) – Old video CD format that supports 74 minutes of MPEG-1 video on a CD

10 DVD

DVD

Proposed by a consortium in 1995, DVD originally stood for “Digital Video Disc” then “Digital Versatile Disk.” Now, it’s just DVD. DVD-Video and DVD-ROM standards were released in 1996. DVD-audio was defined in 1999.

11 DVD

DVD

Consumer products first appeared in 1997. While slow to catch on at first, DVD is now the most successful consumer electronics innovation in history. There are now over 55 million DVD-video players in the U.S., and over 100 million DVD-ROM drives are installed worldwide.

12 DVD-Video

DVD-Video

A standard (DVD-5) DVD-Video disk holds 133 minutes of video encoded in MPEG-2 format. Like videodiscs, DVD-Video supports multiples languages, still frames, searching, etc. Though little used, the DVD-Video format is capable of supporting a multiple camera angle feature.

13 DVD-ROM

DVD-ROM

DVD-ROM is the larger cousin of CD-ROM. One can hold 4.7 GB of data. Recordable DVD formats are still not standardized. However, recorders and players are now available that support most of the competing formats.

14 DVD-Audio

DVD-Audio

DVD-Audio supports high-quality surround sound (5.1 channel) audio at sampling rates of 44.1 KHz to 96 KHz and with greater frequency range than on CD-DA disks. Extras such as images and notes can also be included. DVD-Audio products are now beginning to appear.

Next Generation

Two competing formats are now vying to be the next generation DVD: Blu-Ray from Sony HD-DVD from Toshiba Blu-Ray has a larger storage capacity (25 GB vs 15 GB), but HD-DVD promises to be less expensive. The marketplace will determine the preferred format.
