Glossary
10Base2 − a coax version of ETHERNET. Uses a 4.9 mm (0.19 inch) diameter, 50−ohm coaxial cable (RG−58) and
BNC connectors, but runs at the same speed (10Mb/s) as
ETHERNET. The Jupiter system uses this standard
between VM/SI controllers and Saturn. It is also used by the original
BCS 3000 controllers.
10/100BaseT − an
ETHERNET configuration that uses twisted pair wiring (typically Cat 5 UTP unshielded twisted
pair cable with RJ45 8−pin connectors) to transmit data up to 100 Mbps.
4000 series − (Saturn) these products are very similar to the Saturn 3000 and 3500 series products but have the
“crescent” style front panel.
A board -
ES−3000 used for Thomson Automation applications. Now obsolete.
AA board − analog audio processor for Saturn Master Control switcher.
AccuSwitch − control application for
CM 4000. Provides interface between Grass Valley Crosspoint Bus routers
and certain automation systems, including Thomson Broadcast Automation.
AES − Audio Engineering Society. Internet address: http://www.aes.org.
AES3−1992
AES Recommended Practice for Digital Audio Engineering −− Serial transmission format for two−
channel linearly represented digital audio data.
AES11
AES Recommended Practice for digital audio engineering −− Synchronization of digital audio
equipment in studio operations.
AFV − Audio−Follow−Video. Normal operation of a distribution switcher where selection of a video source
automatically selects audio from that source. Example: selection of VTR1 video automatically selects VTR1
Audio 1 and VTR1 Audio 2 as well.
Alamar − manufacturer of broadcast automation systems. Acquired by Philips.
Ampex bus − see
SERIAL BUS.
Andromeda − logical signal processing system developed by Systems group Griesheim. Functions include eval-
uation of GPIs, tally light control, evaluation of contact closure failure indications from devices such as master
control switchers and video servers, and automatic, emergency switching.
AV board − analog video processor for Saturn Master Control switcher.
BCS 3000 − Bosch Control System. Predecessor of Jupiter Facility Control System, originally developed by
Bosch Video Systems Division (now part of Grass Valley). Used Hewlett−Packard UNIX−based file server.
BCS−3000 controller boards included the CE 3000 Matrix Controller, the SC 3000 Serial Control Interface,
the PL 3000 Party Line Interface, and the VG 3000 Dual Video Display Status Generator. Most of the func-
tions of these controllers were combined in the VM 3000 Control Processor. Some facility control systems
built by
BTS combined BCS controller boards with a Jupiter PC file server.
