That's the term used for the delivery of cinema-quality movies to television households, with each consumer choosing what to watch and when to watch it. But the technical challenges have been a deterrent. The main obstacle for cable systems has been creating and maintaining a sufficiently large database of movies. The problem for Internet systems has been network circuits too narrow to carry data files the size of movies, which can be four billion to nine billion bytes each. In the last year, though, a flourishing digital video-on-demand market has developed, thanks to the least probable of carriers: the United States Postal Service. Because of cost advantages and, in some cases, even an edge in speed, the Postal Service, FedEx <http://www.nytimes.com/redirect/marketwatch/redirect.ctx?MW=http://custom.m arketwatch.com/custom/nyt-com/html-companyprofile.asp%26symb=FDX> and other physical delivery services now seem to be the dominant mechanism for bringing data-rich digital content, on demand, into the nation's households. The secret of the Postal Service's digital success is the DVD <snip> Andrew Odlyzko, the director of the Digital Technology Center at the University of Minnesota, says that the cost to the service provider of transmitting a data file the size of a typical DVD movie over the Internet could be nearly $20. What's more, a home user with a 56-kilobit-a-second modem could wait two weeks for a movie to download - much longer than the three days the post office estimates it would take to mail a DVD coast to coast. <snip> Assuming that the average disc Netflix sends out contains 8 gigabytes, that one company alone may be mailing out about 1,500 trillion bytes, or terabytes, each day. Estimates vary on how much data the Internet carries in North America each day. RHK, a research company in San Francisco, says the number exceeds 4,000 terabytes, while Professor Odlyzko argues that the Internet daily traffic flow is only about 2,000 terabytes - or only about a third more data than the amount Netflix ships. Of course, Netflix is not the only company mailing rental DVD's. Video Store magazine estimates that, beyond rentals, about 1.5 million DVD's, or 800 terabytes, are sold each day through Internet or telephone orders and dispatched by mail, FedEx or other parcel service. David Farber, a University of Pennsylvania computer scientist who was an early architect of the Internet and is a Netflix customer, says that he does not expect the Internet to catch up with the DVD Pony Express any time soon. "It's going to be years before we get the bandwidth," Mr. Farber said. "When I sit back, I want the quality that comes with a DVD; I don't want to look at a 2-by-2 hole, which is what you get with the Internet" when watching video on a computer. Where the Net pays, he says, is when people say, "I want it, and want it now." Meanwhile, watch for high-quality digital movies coming to a mailbox near you. http://www.nytimes.com/2002/09/23/technology/23NECO.html <http://www.nytimes.com/2002/09/23/technology/23NECO.html> ------ End of Forwarded Message ------------------------------------- You are subscribed as interesting-people () lists elistx com Archives at: http://www.interesting-people.org/archives/interesting-people/
