共用题干 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 TV 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 DV D.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 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. The conventional DVD player cannot play any Divx disc because the disc________.
