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 needn"t 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 customer"s Divx account and charged to a credit card. The player"s 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.
