Glossary
crosspoint bus
Also called the matrix bus. A five-pair bus
that carries switching and status commands
between the crosspoint (matrix) cards and
the control device.
D
delegation
Use of a special control panel or supervisory
display to restrict control of a specific VTR to
a particular control panel or panels. The del-
egation process does not actually connect a
control panel to a machine; rather, it allows
the connection to be made using the normal
machine linkage procedures. See also Link-
age.
DHCP
Dynamic Host Configuration Protocol. Pro-
vides automatic TCP/IP configuration when
a DHCP server is present on the network.
DVB-ASI
Digital Video Broadcasting -Asynchronous
Serial Interface.
DSP
Digital signal processor.
E
EBU
European Broadcasting Union. Internet ad-
dress: http://www.ebu.ch/.
ESbus
Nickname for EBU/SMPTE RS-422 bus pro-
tocol for remote control of television produc-
tion equipment using a full-duplex four-
wire, asynchronous serial, 38.4 kbits/s digi-
tal channel. Connectors are 9-pin D. Incorpo-
rates ANSI-SMPTE 207M and
Recommended Practice 113. The Jupiter Seri-
al bus is designed to be compatible with ES-
bus; however, the serial data cable supplied
by Thomson uses only 5 conductors. (In Jupi-
ter systems, “ESbus” usually refers to VTR
control.)
EScontrol
Control of a “remote” (non-crosspoint bus)
routing switcher using proposed ES
BUS
rout-
ing switcher dialect. Also referred to as “ES-
bus Router
” protocol.
ESnet
Nickname for EBU/SMPTE proposed proto-
col for remote control of television produc-
tion equipment based on
THIN
NET
.
ESswitch
control of a routing switcher using a third-
party computer operating according to the
proposed ES
BUS
routing switcher dialect.
Also referred to as “ES
BUS
T
RIBUTARY
” proto-
col.
ESswitch protocol
(a.k.a. “ESW”). Protocol used for control of a
routing switcher by a third-party computer.
It is described in Thomson document “ESs-
witch Serial Routing Switcher Control Proto-
col, Enhanced Version.” This is a simplified
version of the ES
BUS
TRIBUTARY
PROTOCOL
.
ESbus Tributary protocol
(a.k.a. “ESTR” and “ES-trib”). Full tributary
ESBus automation protocol, compliant with
SMPTE EG 29-1993, and all associated nor-
mative references. The protocol supports all
standard bit rates from 300 to 115.2 kBPS.
Flow control is an advantage with this proto-
col.
