demand (VOD) service right now on a test-market basis. VOD ser-
vices use cable to provide homes with an array of services, includ-
ing home shopping, interactive games, on-line banking, and video
on demand.
The DLTtape system provides the high capacity, fast throughput and
total reliability that are a must for video on demand applications.
The DLTtape system can help the VOD service provider deliver
much of the programming and promotional material that appears
on the network. An entire day’s output of editing can be delivered
to the network operations center on a single DLTtape cartridge.
Film studios and distributors can ship feature films to the VOD
service on DLTtape cartridges. A single two-hour movie can occu-
py from four to 40GB of storage space. Special MPEG (Motion
Picture Experts Group) encoders are used to compress movies and
other programs.
Digital Nonlinear Editing
Film editors used to review every foot of film and manually cut
and splice together the sections they wanted in the final version.
Today, film editors are more likely to use a powerful computer
workstation to review and edit their masterworks. These new digi-
tal editing systems feature huge amounts of RAM and a large disk
drive for handling the “hot” project at hand. Just as importantly,
these systems incorporate a powerful tape backup system to store
completed work and works in process.
According to Avid Technology, the industry leader in digital nonlinear
editing systems, the debate is not whether to use digital technology,
but rather how best to implement it. Avid offers DLTtape systems with
all of its digital editing systems. According to the company, DLTtape
drives and media provide the “fastest, most cost-effective method to
