Info

The Future of DVD based recorders are selling well and will add DVD recording capabilities once prices are low enough. Program listings from the Internet can be shown on the TV screen, for instance, so that shows can be marked for recording with the click of a remote control, and the system automatically compensates for delays caused by ball games or newsbreaks. Video game consoles include DVD drives for game play, giving them the capability to double as DVD movie players. In short, because of the flexibility and interconnectability of inexpensive digital electronics, all the independent pieces we have grown accustomed to can be tossed in a big hat, shaken around, and pulled back out as new, mixed-and-matched systems with more features at lower prices. Customers will benefit from, and soon come to expect, personalization, freedom of location, and freedom of time. Our electronic devices will enable us to access anything, anytime, in the way we want. At the end of 1999, digital video products generated 11 percent of the net consumer electronics market revenue. The CEA expects this number to double by 2003. Even movie theaters are being changed by digital technology. Digital cinema trials around the world in 2000 were surprisingly better than almost anyone expected. The digital movie files were delivered on DVD-ROM discs but will eventually be sent over Internet connections. International release dates have been steadily getting closer to U.S. release dates, as the old model of movie distribution has been forced to change by Internet advertising that hits all audiences simultaneously. Movies that used to take six months to creep into theaters around the world now make a worldwide release in only one or two months. DVD in the Classroom 563 Unlike the home entertainment market, where laserdiscs never gained more than a tiny videophile niche, the education market adopted laserdisc technology early on and in a big way. Over 200,000 laserdisc players have been sold to schools in the U.S., almost one for every building. So, the big question is, will DVD replace laserdisc? The answer is no, not directly. Most of the appeal of DVD is lost in a classroom environment. Lessons usually never last more than 45 minutes, so there’s no pressing need for hours of uninterrupted video. Surround-sound audio is pointless, especially since most laserdiscs and VCRs use the cheap speakers in the television. Laserdisc video quality is already as good or better than most of the class-

Multilingual audio tracks and subtitles are nice, but it’s already possible to put four audio tracks on a laserdisc by using both channels of analog audio and both channels of digital audio. DVD’s menus and interactivity are an improvement over passive laserdiscs, but most educators would prefer to make the jump to computers and gain significantly more power and flexibility. Laserdisc players maintain advantages over DVD players, however. Any still picture or movie can be accessed almost instantly by entering a fivedigit frame number on the remote control or, easier yet, by scanning a
