A good example of how broadcast encoding and transmission are changing things from an interview in Videography magazine....
Part of PBS'
educational process included calling upon The Interface Group, a full-service Washington DC
facility, to create special promos and opens to explain different aspects of DTV. As Interface
CEO Tom Angell expalins it, the DTV transition is a brand new world. .....
Videography: Can you provide an example of this?
Angell: Sure. For 20 years we've been shipping videotape--ground-up rust on top of
plastic--to television stations for them to play as spots. Then this past year we put in a DG
(Digital Generations) System for the political season, which was tremendous. We sent out
some 6,000 to 7,000 spots, 95 percent of which were delivered over the DG system. Instead
of FedEx packages containing videocassettes, all of this material was MPEG-compressed,
sent up over satellite, downlinked into some 700 V-SAT-equipped TV stations, stored on hard
drives, and played to the air by library management operations
