Devices and global controls
Some of the Osprey AVStream driver’s controls work interactively. Changes in value immediately
update the video stream output. Examples include brightness, contrast, hue, saturation, and
sharpness.
In some applications, additional tabs may also display. The additional tabs are system supplied, for-
your information only; you cannot set these controls.
The groupings of Osprey board models to driver binaries are as follows (o100, and so on, are short
for Osprey 100, and so on).
o200avs o100, o200, o210, o220, o230
o300avs o300
o440avs o440
o540avs o530, o540, o560
Most Osprey video cards, with the exception of the 100 series, have the ability to present multiple
output streams from a single input device. For example, your company may wish to do a webcast
globally to resellers, users, or potential customers. Using the Filters tab, you can set up different
output streams to accommodate users with different rate modems.
Some changes, such as cropping, logos, and captions, may affect the filter. For example, if you
change the logo on one device and its filter, the logo changes only on that filter (Figure 6).
If you change the values on Video Proc Amp, Video Decoder, Input, Filters, Device and, or RefSize
tabs, the effect becomes global to the card. All characteristics on each device on the card change to
those changed on a single device. This change is limited to the card on which the device changed. If
you make changes on an Osprey 230 card residing with an Osprey 530 card, a change on the Osprey
530 will not affect the Osprey 230 devices.
