Video Decoder tab
The Video Decoder tab (Figure 17) is a Microsoft DirectShow control for setting the
NTSC/PAL/SECAM video standards. PAL and SECAM are standards used in Europe and other parts of
the world. Osprey cards can function in computers in various countries with different standards.
These controls are also on the Input tab. Most users will find the Input tab more convenient.

Changes apply to all video previews and stream captures on the currently selected device. If you
have multiple Osprey cards, you can set the input individually for each of them. Changes made with
this control take effect immediately. If video is running and a standard is selected that does not
match the incoming signal, the video is likely to freeze or glitch until the signal matches the correct
standard.
Osprey boards support the “Signal Detect” (0 or 1) and “Lines Detected” (525 or 625) status
readouts. They do not support the VCR Input or Output Enabled controls, which will always be
disabled.
