Use the Closed Caption page to enable or disable Closed Captioning, and to control its characteristics.
Closed Captioning is a method of encoding and displaying text such as movie dialog captions and stock quotes as part of NTSC video. The text is similar to movie subtitles in appearance. Closed Captioning is widely available on broadcast video, cable, videotapes, and videodisks.
The Osprey Video Capture Driver provides a complete implementation of the Closed Captioning standard, and also provides special extensions that are made possible by the special capabilities of a PC.
You can use Closed Captioning whenever you can meet the following conditions:
You must be viewing a videotape, videodisk, or broadcast material that has Closed Captioning content. There will be a small "CC" logo on the packaging or in the program listing.
Closed Captioning is for North American NTSC video only, not for PAL or SECAM video.
Closed Captioning must be enabled in the Osprey driver, using the Closed Caption dialog page as explained below.
Video Mode, and Channel 1 must normally be selected, as explained below. You might use Text Mode or Channel 2 in specialized instances.
In addition to the normal options of viewing or capturing Closed Captioning, you have the following special capabilities:
You can save the text to file as you view it or capture it.
If you are a software developer you can write a Video for Windows application that receives decoded Closed Captioning text from the Osprey driver and searches it or processes it in any way you see fit. Contact mailto:support@ospreyvideo.com for more information about this capability.
