理工类辅导资料:概括大意DVD for Rent
1 A pay-for-play system for video DVD will emerge by summer as an alternative， and possibly a competitor， to the DVD format currently available.
2 The new system， called Digital Video Express （Divx）， operates like a DVD player， except for the specially coded discs. These will cost $5 for initial viewing over a 48-hour period and can be viewed again for additional fees and even purchased for unlimited viewing.
3 Divx combines the service of a video rental （出租的） store with the operation of a pay-per-view “IV channel. Unlike a rented videotape， though， the Divx disc neednt be returned. Customers can retain the disc for replay in the future at an additional fee， or simply throw it away.
4 Subsequent plays， or the purchase of unlimited-viewing rights， are billed to the customers Divx account and charged to a credit card. The players built-in memory keeps track of all Divx plays， and sends this information by toll-free phone modem （调制解调器） to the Divx record-keeping centre. Each Divx disc and player has a unique identification code， so the system knows which discs have been played and where.
5 Some Divx discs could be converted for unlimited play at a price likely to be lower than buying a conventional DVD. Others， called Divx Gold， would be sold from the beginning for unlimited play without further charge. Although conventional DVDs will run in a Divx player， conventional DVD players will lack the decoding （解码） and communications ability to play Divx discs. Divx players will be offered by Panasonic， RCA， and Zenith.
6 About 100 discs will be available initially from Disney， Dreamworks， Paramount， and Universal， growing to 500 titles within a year. Other film makers have yet to adopt the Divx system， which is owned by retailer Circuit City， the 350-store electronics chain that bankrolled （提供资金）its development.
