3200/6400 MATRIX

VIRTUALIZATION

by Roger McCarten,

Product Manager

Last year, Extron introduced its new

32 x 32 and 64 x 64 matrix switchers,

the Matrix 3200/6400 Series. These new

switchers have been designed for ease

of use. From the start, Extron’s

engineers sought to design a matrix

system that would be versatile and easy

to upgrade—by the user. With the

Matrix 3200/6400 switchers there is no

need to send any part of the matrix back

to the manufacturer for upgrade or

reconfiguration. These operations can be

done easily by the user in the field.

VIRTUALIZATION:

THE KEY TO VERSATILITY

One of the features that make the

3200/6400 matrixes so versatile is

virtualization. Virtualization allows the

user to electronically create switching

planes of varying size and number as

needed. (A switching plane can be

thought of as an individual matrix

switcher—electronically created within

a physical switcher.) Through virtual-

ization, multiple switching planes can

be created, or mapped, within one

physical switcher.

Figures 1A & 1B demonstrate the

concept of switching planes and virtual-

ization. Figure 1A shows a physical

switcher (Extron’s Basic Module

Enclosure or “BME”). This is a low reso-

lution BME that has been electronically

mapped out, through virtualization, to be

a 32 x 32 switching plane. Therefore, this

physical switcher will behave as one

32 x 32 composite video switcher.

Through virtualization, this same

physical switcher (BME) can be elec-

tronically re-mapped into three inde-

pendent 8 x 8 matrix switchers. This

way the same physical unit can be

mapped to be an 8 x 8 composite video

switcher and an 8 x 8 S-Video switcher.

The bottom two 8 x 8 planes will

switch together to handle the Y and C

channels. Figure 1B shows this re-

mapped switcher.

One of the advantages of virtualization

is demonstrated in Figures 2A & 2B.

Suppose a user has one physical

switcher, as shown in Figure 2A. This

is a 64 x 64 BME. Currently it is being

used to switch R, G and B and has

been mapped out as a 21 x 21 RGB

switcher (3 switching planes, one each

for R, G, and B). Suppose the require-

ments change and there is a need to

increase the matrix size to 32 x 32?

With virtualization, this can be easily

accomplished. Simply add a 32 x 32

physical switcher (BME); then use

virtualization to re-map the two BMEs

into a 32 x 32 RGB virtual matrix. The

resulting switcher can be seen in

Figure 2B. Here the physical units have

been re-virtualized and three switching

planes for R, G and B now exist on the

two physical switchers.

IT’S EASY

Extron’s matrix control program makes

virtualization easy. The 3200/6400

Series switchers can be set up with

Extron’s Windows-based matrix control

program. With this program, the user

simply indicates the size and type of

the desired switcher, and the program

will map out the hardware to create the

desired virtual switcher. The program

will also provide printouts of the

resulting configuration, i.e., indicating

which outputs have been assigned for

which color and sync signal.

If a hardware upgrade is required, this

is also easy. Extron’s 3200/6400 Series

matrix switchers can be upgraded in

most cases by adding circuit cards to a

BME or by adding a BME. Either of

these operations can be done easily in

the field. Once the hardware upgrade

has been done, Extron’s matrix control

program can then be used to create the

desired virtual switcher.
