HDNet Distributing Shuttle Launch Video
LOS ANGELES (AP) -- High-definition television network HDNet said Thursday it is making available a free 20-minute video clip of last week's Discovery space shuttle launch for download over the Internet.
Dallas-based HDNet, whose high-definition broadcasts of sports events, concerts and television shows are carried on several satellite and cable television systems, touted Internet delivery of its programming as a way to expand its audience.
Computer users who go to HDNet's Web site () can retrieve the file, but instead of downloading it from a central server, the company has opted to distribute it over a peer-to-peer, or P2P, network.http://www.hd.net
P2P networks take bits and pieces of data from computer users who already have a version of a given file and copy it to another computer. The method is considered a faster and cheaper means of transferring data over the Internet than doing so from a single computer server.
HDNet's shuttle video is 1.3 gigabytes, said Travis Kalanick, founder and chief executive of San Mateo, Calif.-based Red Swoosh Inc., which makes the software used to distribute the video.
Large movie and video files are routinely distributed online over P2P using file-sharing software like BitTorrent, but most of the people swapping the files are doing so without permission.
"This is the first time that high-definition TV is being openly distributed on the net," Kalanick said.
