A Homework Assignment! I need some Empathy Over Here!

This Topic has been Blogged about before, but, the situation has gotten worse since Harry Kalas died! I am talking about "Closed Caption TV" ! Everyone that has CC capability is required to watch Two Innings of Phillies Baseball with Closed Caption On! Tonight alone they ...
  • Typed Citizens Bank Park as "Sid's Bank Park"
  • Dodger pitcher Will Ohman was identified as "Woman O Man"
  • Jayson Werth "singed in the Fourth"
  • and Finally, Tom McCarthey says, "and Jason Werth steals Home! Oh!..." is typed as "Jason Worse feels homo!"
I could go on...is this stuff being transcribed in India and then recycled? Cause there is quite a Time Delay...

I realize that this is a point of irritation for you Pea...as you have commented on it in the past..however, it doesn't even make my top 500! So, you'll have to go it alone on this one...zzzzzz!

For live programs, spoken words comprising the television program's soundtrack are transcribed by a human operator (a Speech-to-Text Reporter) using stenotype or stenomask type of machines, whose phonetic output is instantly translated into text by a computer and displayed on the screen. This technique was developed in the 1970s as an initiative of the BBC's Ceefax teletext service.[5] In collaboration with the BBC, a university student took on the research project of writing the first phonetics-to-text conversion program for this purpose. Sometimes the captions of live broadcasts, like news bulletins, sports events, live entertainment shows, and other live shows fall behind by a few seconds. This delay is because the machine does not know what the person is going to say next, so after the person on the show says the sentence, the captions appear.[6] Automatic computer speech recognition now works well when trained to recognize a single voice, and so since 2003 the BBC does live subtitling by having someone re-speak what is being broadcast.

In some cases the transcript is available beforehand and captions are simply displayed during the program after being edited. For programs that have a mix of pre-prepared and live content, such as news bulletins, a combination of the above techniques is used.

For prerecorded programs, commercials, and home videos, audio is transcribed and captions are prepared, positioned, and timed in advance.

For all types of NTSC programming, captions are "encoded" into Line 21 of the vertical blanking interval – a part of the TV picture that sits just above the visible portion and is usually unseen. For ATSC (digital television) programming, three streams are encoded in the video: two are backward compatible Line 21 captions, and the third is a set of up to 63 additional caption streams encoded in EIA-708 format.[7]

Captioning is transmitted and stored differently in PAL and SECAM countries, where teletext is used rather than Line 21, but the methods of preparation are similar. For home videotapes, a variation of the Line 21 system is used in PAL countries. Teletext captions can't be stored on a standard VHS tape (due to limited bandwidth), although they are available on S-VHS tapes and DVDs.

For older televisions, a set-top box or other decoder is usually required. In the US, since the passage of the Television Decoder Circuitry Act, manufacturers of most television receivers sold have been required to include closed captioning display capability. High-definition TV sets, receivers, and tuner cards are also covered, though the technical specifications are different. (High-definition display screens, as opposed to high-definition TVs, may lack captioning.) Canada has no similar law, but receives the same sets as the US in most cases.

Wedgebreaker, that is exactly what I told them at the NCAA final four party. They don't listen. By the way, I'll be down the shore 7/11 to 7/18. Any chance of staying at your place with the 12 young ladies?? Me and Stoney are coming together.

This old time fan detests it...LET ME WATCH THE DAM GAME!!!!!!! Have you been to a game in person lately? It's punishment w/ the loud music blasting, to say mothing about the style of music (sic). Then the floor games like golf, sack races during time outs, trampoline acts between quarters, and on and on. Get rid of the ads and info while the game is on the screen. There's toooooo much info in the world...and it's all a distraction. By the way, Jason, you need a girl or a hobby!!!!!!!
