NB to Test Delivering Video via Computers: The test using computers and high-speed telephone lines to deliver news and other video feeds to its affiliates is part of a partnership to be announced today with MCI Communications Corp. The system marks the first time a major network has used digital technology to deliver programming on demand. It also hints at a time when consumers will be able to access video programs whenever they wish. NBC will use a new MCI service called Hypermedia to let 20 of its affiliates download onto computers news reports at any time. TV networks now send news footage and commercials via satellite broadcasts, which the affiliates must videotape.
