I've done a lot of googling on the subject, and ended up with a mishmash of sort-of-conflicting information! You may need to include more info for this to be useful to the entire mythtv audience. Someone please correct me if I make any mis-statements below. This is not anything close to an area of my expertise. Closed Captioning as I know it is specific to NTSC broadcasts. Teletext is specific to PAL broadcasts (is it really that simple?) I *think* I read that closed captioning *works* in mythtv for BT878-based cards, but not for anything else. I, too, would love to eventually be able to mute the TV and read Closed Captions. To kick things off, I created a matrix, with lots of unknowns, at HYPERLINK http://www.mythtv.info/moin.cgi/CaptureCardMatrixhttp://www.mythtv.info/mo in.cgi/CaptureCardMatrix . I'll be happy to maintain it based on whatever I learn from the list, but anyone should feel free to edit it; that's the wiki spirit! That's a great start - Thanks! -Ross ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
[mythtv-users] Re: Closed captioning support
I would want CC support that for example, did not display during normal play but did display at 3x and 5x FF speeds, or did other clever things like knowing about letterbox or pillarbox bars and making use of them or even an FF mode that shrunk the display window down to make room to do a lot of text on the screen at once. A tool like that you really could watch a show at 3x or 5x speed, at least the boring parts. sounds like a speed reading torture device :) . I remember having something like that in middle school where a bar zipped down a page and you had to keep up. Semi-related does anyone else feel like timestretch is there to challenge how fast you can watch TV? Do you think people can learn to watch TV faster just like people learn to read faster? Is there an upper bound to this? I wonder what brain signals look like for someone watching TV at 1.7X vs. someone watching at 1.0X. My untested hypothesis is that while people zone out in front of TV at regular speeds, watching TV at timstretch factors above 1.5 requires more viewer attention and participation and could be a significant mental stimulus as opposed to an opiate or eyeball massage. I can just see it now... yuppie parents sitting their kids in front of mythtv to watch Baby Einstein videos at 1.7X speed /Semi-related My point is that just passing to the TV is great for the deaf, but there's a lot of cool things that nobody has done with CC and subtitles for the hearing. .. like being able to search your recorded TV shows for text and jump to a point based on subtitles (sort of like this: http://video.google.com/videosearch?q=dvr ) or being able to pause TV and select a word out of the CC text and then either jump to a wikipedia definition or a webster's definition or hear the word pronounced or find other recorded programs containing this word' or sync lyrics to music videos or sync text or audio or video commentary from various sources to video or show subtitles to a movie in another language from possibly - maybe even do realtime translation CC data could provide the elusive synchronization link for many types of other critic or commentary data (think DVD director's commentary) from external sources - CC data should be like a reliable video timestamp regardless of where the program is shown, how it is recorded (as long as CC data is included), when the recording starts/stops, and what speed it is played back at. Imagine being able to record your commentary as you watch a program and then letting your friend be able to watch that same show and listen to your stupid wise cracks and inane banter or interruptions. It could be anywhere from exceptionally annoying to just like MST3K. you could have your spare tuners watch certain channels and scan CC for phrases and record an arbitrary amount of time before and after any key words or phrases and store those clips or switch to livetv and override to show a predefined news alert that was defined as critical. -Ross ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

Do you think people can learn to watch TV faster just like people learn to read faster? Is there an upper bound to this? Read up on rapid serial visual presentation. Basically, with a little practice, you can learn to read (and take in information) much faster than your brain can subvocalise the text. I'm not sure how this compares to auditory processing, but it seems logical that the eyes have a higher bandwidth than the ears, so with subtitling it should be possible to watch TV at stupidly high speeds. I can certainly follow relatively slow programming at 1.6x or more with subtitles while I lose the plot with audio alone at about 1.4x. That may say more about my own (suspected dodgy) auditory processing than anything else, but it's still rather cool. I wonder what brain signals look like for someone watching TV at 1.7X vs. someone watching at 1.0X. My untested hypothesis is that while people zone out in front of TV at regular speeds, watching TV at timstretch factors above 1.5 requires more viewer attention and participation and could be a significant mental stimulus as opposed to an opiate or eyeball massage. I wouldn't be surprised if it became easier with practice. Which would mean you could turn the speed up and up until reaching some sort of bandwith limit (eventually the audio will turn to mush, and the video will drop so many frames it'll stop making much sense), probably determined by the amount of actual 'content' in the programme. I can just see it now... yuppie parents sitting their kids in front of mythtv to watch Baby Einstein videos at 1.7X speed I need a 1.0 time stretch factor to make sense of most modern children's TV.
