CC Pin
Figure 40. CC Pin
This group controls whether the closed caption character pairs emitted by the DirectShow CC pin are
from Field 1 or Field 2 of the video. The DirectShow specification is that CC on a CC pin is always
from Field 1; however, this extension allows application developers to access Field 2 data such as
XDS data (including vchip) via a DirectShow standard pin.
