Channel AutomationChannel Automation
• Harris Louth– http://www.broadcast.harris.com – Controls master control room
equipment• Flexicarts, vtrs, switchers, routers,
character/bug generators– Frame accurate control of devices– Backend infrastructure – source for
multiple channels• Separate transmission lists:
ResearchChannel, UWTV, UW2– LAN attached “Air Clients” provide
live control– Translators for traffic systems like
ProTrack • Harris ADC binary format
Digital InstantiationDigital Instantiation
• Injestion– Tapes Received– Dub copy for
broadcast tape library
– Tape metadata stored in ProTrack
– MPEG2 encode– Transcode to other
formats• FlipFactory
– Archive digital assets
