Title: Closed Captioning Support? Post by: miltiades on October 29, 2006, 08:44:18 PM Hi all,
I'm an electrical engineer with profound hearing loss. As such, I am extremely interested in closed captioning. Does anyone know the current status of closed captioning support? I'm guessing it's not a supported feature (it's not exactly a high selling point for the consumer ;D) I would like to develop this feature, but first I need to know if it's even possible. In the US, closed captioning is part of the analog video signal, hidden in line 21 of the vertical blanking interval (i.e. it is not seen on displays). Would it be possible to even access this information? This is going to depend on how the blanking portions of the signal are handled, and how much control over the A/D and DSP core we have. If the device can access the blanking period, I would love to develop code to overlay this onto the top or bottom of the display at the user's discretion! Thanks!

Actually, this is pretty important feature to me too, I put a bug in on this, but it sounds like it needs to be split up and better articulated (divx subtitle support v. recording closed captioning, etc) anyone who knows this stuff, please help out http://bugzilla.neurostechnology.com (http://bugzilla.neurostechnology.com)
