[不定项选择题]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________.
A.will not be taken back by the shop
B.is specially coded
C.is bankrolled by儿nasonic,etc
D.is likely to be cheaper than the conventional DVD disc
E.has been played and where
F.is owned by retailer Circuit City
