CC Pin
Figure 49. CC Pin
This group controls whether the closed-caption character pairs the DirectShow CC pin emits 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 including XDS data (such as
V-chip data) via the standard DirectShow CC pin.
For most purposes, including scripting in applications such as Windows Media, you will want to select
Field 1. Field 2 is mostly for custom applications.
A video capture filter’s CC Pin is separate and independent from the video capture and preview pins, as
well as from the driver’s rendering on video function.
