    DVD RW Format Wars - Which one's winning?

    Sigh. I'm not sure you understand the situation with DVDs. And when you toss around names like that, as if the tail wagged the dog, your circular argument fails. Let me see if I can straighten this out for a second. Long, long ago, in a land, far, far away, there were FORMAT WARS. And this ain't a play thing, this is the very soul of modern society. Modern media includes all mega corporations and multinational businesses engaged in trillions of dollars in product. The stakes could not be higher for the entire world. This war was not started recently. It's been going on for decades. VHS/Betamax. CD Standards. DVD standards. It's all about the patents and the royalties. Because without those, these companies wouldn't make very much money back on their investment into developing these media. First off, props to Sony for doing so much over the years. But in the DVD arena, I am not for Sony and the +R/+RW. The whole story is a bit longish, but interesting, and you should read it for yourself in DVD Demystified, by Jim Taylor, author of the DVD FAQ. First A Little Video History Videotape recording for the home started in 1965 when Phillips and Sony introduced a B&W reel to reel system for about three grand. The alliance between those companies persists to this day and is central to the DVD wars. Sony came out with a video cassette tape system in 1972 and released Betmax in 1975. In 1976, JVC released the VHS format, which was lower quality but won out because it was the chosen format for pr0n. It was also 1/3 the price for a VHS tape deck. Phillips and Pioneer released videodiscs in 1978. Those were the big record sized discs. Now everybody tried to get into this arena but we don't hear much about their failed attempts. MCA came out with DiscoVision in 1979, and in 1981 RCA came out with SelectaVision, which failed for technical reasons. JVC and Matsushita (Panasonic) came out with VHD shortly after, and it was not a big hit, being sold in Japan and in England. JVC introduced S-VHS in 1987. Onto CD History Sony and Phillips released CD-DA in 1982, which is an audio cd. The technical specifications book had red covers, so this was called the Red Book standard. In 1985 we saw the CD-ROM format appear, and it was a kick to get ahold of one of HPs early recorders and try to make it run on Windows 3.11. Later some crazy standards like CD+G and CD-Video and CD-i were released, but we can forget about those. Because CD-ROMs were designed by different manufactureres, who had their hands in Operating Systems at this time, like M$, there were several filesystem formats. In 1986, industry reps gathered at the High Sierra Hotel and Casino near Lake Tahoe, and delveloped the High Sierra Format. Because it had to support MS-DOS, it was restricted to 8.3 and didn't work well for Apples and Unix boxes. This is called ISO 9660. To it, people have added extensions to make it work with longer filenames. Unix created RockRidge extensions. Microsoft created Joliet extensions. In 1989 there was the Yellow Book standard, CD-ROM XA, which mixes sector types and can interleave data and audio. In 1990 there was the Orange Book standard for Magneto Optical ( MO ) drives. Orange book Part II is CD-R. In 1991 is was Sony with the Mini-Disc. Kodak and Phillips developed the Photo CD in 1992. Orange book Part III is CD-RW, came in 1997. Now for DVDs In 1993, there were sputtering attempts at high quality video by a few small players. Sony and Philips chimed in and said they were working on something. Toshiba said it was too. Hollywood got together and demanded a standard. Columbia (Sony), Disney, MCA/Universal (Matsushita/Panasonic), Paramount, Viacom and Warner Brothers were all calling for things liks 135 minutes of space and other standards. You see, standards are good. Well, when there's all those big players, that means splitting the pie many many ways, not just between Sony and Philips. So they tried to make their own DVD format. In late 1994, Sony and Philips came out with their own 3.7 GB Multimedia CD, MMCD, single sided disc. A month later, all the other big companies listed above came out with their own standard, the Super Disc, SD, a double sided 5GB per side disc. Seven super big companies and the SD format. So Philips and Sony gathered over 10 companies to their side. But computer companies balked and said, HEY, get your act together. Apple, Compaq, HP, IBM, and M$ now now demanded a standard that said these DVD drives must be able to read CDs and CDRs and CDRWs. "Sony refused to budge and a month later said there would be 'no adjustment in it DVD standards' Norio Ohga said, '. . . a split on the standard is unavoidable because we are in a world of democracy.' He rejeced the possiblilty of a third standard and defended his decision ont he grounds of 'liberalism and democracy.'" p.49. IBM told Sony they were going to side with the SD camp and Sony caved, and over the next three years all these groups hammered out the standards and evolved the main committee into the DVD Consortium: Philips, Sony, the SD camp (listed above), and Time Warner. 4000 patents. Matsushita: 25% of the patents Pioneer: 20 % of the patents Sony: 20% Philips, Hitatchi, Toshiba: 10% Thomson: 5% Mitsubishi, Time Warner, JVC: negligible Well at this point, we begin the whole DVD-RAM and DVD-R and DiVx stories, and guess what, I'm tired. So you'll have to buy the book. But the bottom line is that DVD-R and DVD-RW are the approved official standards from the DVD-Forum, as is DVD-RAM. DVD+R and DVD+RW are renegade formats being run out by Sony and Philips and HP so that they can hold all the royalties between three companies. Their egregious format was considered and holds no advantage, so it was not chosen by the Forum. Go with the standard DVD-R, DVD-RW, DVD-RAM. okey naw, matthew
