CD-ROM drives are rated with a speed factor relative to music CDs. If a CD-ROM is read at the same rotational speed as an audio CD, the data transfer rate is 150 Kbyte/s, commonly called "1×" (with constant linear velocity, short "CLV"). At this data rate, the track moves along under the laser spot at about 1.2 m/s.
For viewing MovieCDs, Sirius recommended a 486 processor or higher, at least 8 MB of RAM, and a 2x-speed CD-ROM drive (most MovieCDs had a data rate of about 280-300 kB/sec). [6] MovieCDs had a running time of about 45 minutes each, so feature films often were stored on two or three discs in one box, and the consumer had to swap discs to watch ...
Its sequel, Wing Commander IV: The Price of Freedom, used a similar custom movie codec in its CD-ROM release, but a later limited-volume DVD-ROM release saw MPEG-2 DVD-quality movies that far exceeded the original CD release in quality. A hardware decoder card was required at the time to play back the DVD-quality video on a PC.
CD-Cops Requires the user to enter CD-code (or reads embedded CD-code) that describes geometry of CD to correctly locate data on the disc. SafeDisc (versions 1–5) Adds unique digital signature at the time of manufacturing which is designed to be difficult to copy or transfer so that software is able to detect copied media. SafeCast
MovieCD, by SIRIUS Publishing, Inc. (1995?), is a format that uses a traditional CD-ROM disc for playback on a Windows PC containing a video file of a movie encoded in a proprietary codec developed by the publisher (the MotionPixels codec, also used in some PC video games in the mid-to-late 1990s), with the disc also containing codec and ...
TV DVD combos, combining a standard definition CRT TV or an HD flat panel TV with a DVD mechanism under the CRT or on the back of the flat panel, and VCR/DVD combos were also available for purchase. [44] For consumers, DVD soon replaced VHS as the favored choice for home movie releases.
The rest of the tracks are usually in CD-ROM XA Mode 2 Form 2 and contain video and audio multiplexed in an MPEG program stream (MPEG-PS) container, but CD audio tracks are also allowed. [4] Using Mode 2 Form 2 allows roughly 800 megabytes of VCD data to be stored on one 80 minute CD (versus 700 megabytes when using CD-ROM Mode 1). This is ...
This list is not necessarily complete or up to date - if you see a manufacturer that should be here but is not (or one that should not be here but is), please update the page accordingly. This list only lists manufacturers - not brands. For example, many Maxell DVDs are made by Ritek or CMC magnetics.
