hands of a conventional clock display. Power requirements

+5V at lA maximum. 4U BMM unsupported card with 57-way

double-sided edge connector and PN1/29J panel. Parent

equipment GE1M/597. DD 1980.

Video Display Generator. This unit forms the heart of an

electronic symbol generator using the method to run-length

encoding. It converts a sequence of data bytes,

corresponding to run-length and colour information , into

five binary video signals which can, for example, be used

to select one of 32 different colours to each point in the

picture. The data input format is similar to that used by

the Programme Computer, although a link option allows a

simpler format to be used when a two-bit video output is

adequate. Picture data is read either from an on-card

2Kbyte EPROM, from an external PROM card or by DMA from a

microcomputer memory. The unit is compatible with the

Designs Department 280 bus. Feeds of mixed syncs and mixed

blanking are needed.

Power

requirements +5V at 1.7A

maximum. 4U unsupported card with 57-way double-sided edge

connector and PN1/29J. DD 1980.

Black Level and Burst Generator. Generates composite black

level with colour burst from mixed syncs, Burst Gate and

Colour Subcarrier. Power requirements mains. CH1/64A.

Supersedes GE6/504. DD 1980.

Black Level and Burst Generator. Generates a composite

Black waveform including the synchronising burst, to System

I Spec. Input requirements are mixed syncs, burst gate,

and colour subcarrier. Two outputs at 75Q are provided.

Includes Termination Panel PA20/519. Mains power required.

CH1/64A. Supersedes GE6/504. DD 1980. DDMI 8.626(80).

EDI 10414(1)AUG81.

Digitally Originated Graphics Generator. The equipment

generates symbols which have been programmed into EPROMs

contained within the unit. The input signal requirement is

composite video or mixed syncs and the equipment will

provide an output of either RGB or the symbol inserted into

the video signal, together with an output of the symbol

only. According to the storage requirement of the symbol,

a number of

symbols may be

selected remotely.

Power

requirements 240 Vac. 1 U high full width chassis. Sub-

units GE6/552, UN26/557. DD 1981.

Digitally Originated Graphics Generator.

This

unit

is

mechanically identical to the GE6M/548 but is fitted with

the UN26/557A instead of the UN26/557 so as to enable

precise colour matching of the RGB outputs to another video

source. Power requirements 240 V ac t10%. 1 U high full

width chassis. Sub-units GE6/552, UN26/557A, GE6/553,

UN26/564. DD 1982.

Soft Edge Key Generator. Accepts video and mixed-sync

signals and soft-clips the video to generate a key signal.

Has provision for an additional masking signal input to

mask off unwanted key areas. Power requirements +12V, -6v

(from SE3/506). 4U, J-width pcb with panel and 32-way G06
