support hardware that are in widespread use and are marketed by their manufacturers as 'mass

products' - insofar as this can be said about products of the broadcast industry,- with an excellent

price value ratio.

1. The products of the following manufacturers are supported as broadcast video hardware:

a. All Blackmagic Decklink cards or Multibridge boxes. Some of the cards do not support

some or all form of keying, these are not very useful for a CG application. See the

Blackmagic web site for details.

The Blackmagic cards are of good quality, easy to use and cheap. When used for CG however

they have one rather big disadvantage: they only work as either as input or as an output device

but not simultaneously. Therefore Nemo can use them only to output video and key signals,

there is no real time video input. For simultaneous input, you need to use a second card.

b. Bluefish444 Greed and its derivatives, Epoch Series, Supernova series.

Bluefish is a recognized name in the world of broadcast PC products. Justifiably so due to the

quality and reliability of their product. The Greed line of cards use SD definition, some of them are

output or input only. Epoch is the new line of Bluefish cards that supports SD and HD and is a

tremendous value for money. Supernova is their latest card that offers the best in flexibility, all of

their connections can be configured as either input or output. This is the best card for dual

channel operation.

c. DVS SD Station Pro, Centaurus II, Centaurus II LT, Atomix line

DVS is a German company also well respected in the broadcast industry and are the

manufacturers of excellent quality boards. For HD resolution and simultaneous input and output,

both the Centaurus II and Centaurus II LT cards are supported.

d. For template design or preview output, a good VGA card is all that is required.

In addition to cards producing broadcast signals, the most important part of the system is the

GPU (i.e the VGA card that works as a 3D accelerator as well). Nemo basically supports cards

made by nVidia, among them those equipped with the G80 or newer series GPU (since the fall of

2006 all of them belong in that category). We still experience issues with AMD cards therefore

they are not recommended. If it comes to the question of buying a new card, an Nvidia GTX650

would be the minimum you need, probably well suited for general, SD resolution tasks. Especially

for HD purposes, the optimum choice would be the best Quadro board, the fastest (and of course

the most expensive) one. You could opt for the best of the much lower priced Geforce line with

confidence, though. The current top of the line is the GTX780, but we could achieve very good

performance even with dual HD output using the 'lower high-end' GTX760 and GTX660.

3. CPU:

3D requires at least a dual core CPU, although its suitability is limited. For template design and if

only VGA output is used, a faster dual core processor is OK. In all other cases the minimum

requirement is a quad core or more. Nowadays this is not an extraordinary requirement. For HD

resolution, even the fastest possible I7 quad-core processor would not be excessive.
