Harris ADC Device Server User’s Guide
8Introduction
is distributed as needed. The Device Server computer performs real-time work
while the client computers are available for non-real-time work such as editing
playlists, media verification and as-run logging.
◆ Multi-user. The local area network architecture allows for almost any number of
users to access the ADC Device Server simultaneously.
◆ Automated Recording. Satellite or other feeds can be recorded through a record
list. An optional secondary record event allows for recording and segmenting of
live material for playback.
◆ Cart Machine Handling. ADC Device Server’s interface to cart machines is at the
lowest possible level. This allows for greater control of the resources and more
efficient operation. The interface displaces the cart machine’s operating system
and application and related hardware (which reduces the cost of using the cart
machine).
◆ Video Disk Expertise. The Harris disk protocol was introduced to be an industry
standard for controlling disk systems. The protocol has since been adopted by
companies such as Tektronix and Hewlett Packard. The protocol enables these
disk devices to be used as multi-channel cart machine replacements.
◆ Compilation. With the compilation feature, spots can be compiled onto a single
tape.
◆ Multiple Lists/List Types. The ADC Device Server can run up to sixteen lists at
the same time from one Device Server. The lists can be playlists running
independent channels or they can be a combination of play, compile and record
lists, media and GMT lists.
◆ Air Protect. The ADC Device Server supports the simultaneous playing of two
copies of media in two similar devices where one copy is an air copy and the other
a protect copy. This feature is used to protect program or commercial material on
tape, compiled tape or spot material recorded on duplicate video disk servers. A
failure detected by the ADC Device Server of the on air device results in the
automatic switching of the protect device to air. Operators have the ability to
manually switch the protect device to the air feed for such failures as head clogs
or audio/video problems.
◆ Windows NT® Operating System. The ADC Device Server runs on the Windows
NT operating system.
