D
DA board
Digital audio processor for Saturn Master
Control switcher.
DDE
Dynamic Data Exchange. A form of interpro-
tocol communication that uses shared mem-
ory to ex change data between applications.
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.
DV board
Digital video processor for Saturn Master
Control switcher.
DVS
(Philips) Digital Video Systems. Successor to
BTS. Now part of Thomson Broadcast and
Media Solutions.
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-Thomson manu-
factured) routing switcher using proposed
ES
BUS routing switcher dialect. Also referred
to as “ESbus 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 .
