I've written a directshow filter to grab the closed captioning from my Osprey-210 card. The problem is on certain channels ( Bloomberg TV for ex ) on digital cable - I'm getting a 'control' string ( Default URL string[75f4] ) showing up in the cc data. When I open up the Osprey CC Demonstration program on this card, this string isn't rendered on the video, but does show in the text box underneath. My question is : is there a different parsing going on for the video box than in the text box below? Is there a standard I can reference which shows how to properly handle this sort of stuff. Thanks!
