The development of TV subtitles

1 Telecine, and the black-and-white TV slide
Movies to TV, How to be able to see when the TV was first invented, the most urgent problem was. Projector or stereopticon of optical imaging devices to convert the TV signal, urgent geotyijiyo Why beolmyeong telecine (Telecine). You (Nega) telecine to be able to preserve the image of the film later in early development, but simply as a TV so you can see that the objective was. Telecine stereopticon, such as still images, of course, to convert the animated movie was made.
The necessity of the early black-and-white TV even if the TV subtitles will appear. Was the right way to handle this subtitle for a slide.
Create this slide photoconductive also have been daunting.
First write or white ink on black paper design and typeset letterpress print shop like the the black paper on it topically. Phenomenon of the white letters you take a picture of the original print to make the film and engage. Now 35-millimeter film and the film that has been used. You a sheet of sheet of film slide mount fixed to the slide (hardcover) cut in the subtitle for a slide is inserted until the completion. Organize the subtitle in order to fit the slide is used for broadcasting urgent cases being, even if it carries over playing slide jumbled frustration worked. Old TV in the subtitle of the paper because it was created through a process so complex subtitles only just a few of the applications that you have started. '
Also, was a primitive way of these days to see a lot of shedding subtitles, turning the flowing long black or white letters on a piece of paper, add a turn using hand-rolled fabric and later connected to the motor by writing to
And the case of black-and-white TV, because the insert based on the contrast of the screen and subtitle subtitle Subtitle did not have days outside the course and complexion.

2 To the development of FSS (Flying Spot Scaner)
If news like rapidity life was gradually increased need of subtitles on the TV, as well as, in particular, because of the slide above the production process is too cumbersome it was. Is why I developed the FSS. The FSS is designed omitted and the slide of the production process, the process of creating a negative (or clicker) Black Edition directly to get the subtitles manner. The principle is similar to the overhead projector using a mirror reflection of the subtitles directly into the TV camera for crushing can catch Jack.
Especially news programs from the FSS FSS card occupies a large amount, that shines, but was difficult to organize, the problem can not be modified.
FSS with the slide started broadcasting in color after a while can be useful. CG to emerge until

3 CG (Character Generator) the emergence of
Development of computer breakthrough lays the electricity in the TV broadcast. Is finally banging on the keyboard of the PC as we can create subtitles for TV CG instrument appeared. Sheet of Schedule CG Equipment General PC TV signals output cards simply have been resolved.
CG advantage of the rapid production of subtitles, easy to modify, and a few hundred chapter subtitles diskette One 'solve storage varied, depending on the development of a variety of fonts and handwriting illuminate groundbreaking was The initial equipment of CG, but can only use fixed font letter PC specifications high quality graphics card and evolve the design or even figure were to be solved by CG equipment. Yet to resolve all of the issues, however, was not. Colorful effects inside one of the letters TV screen quality as the black letters became necessary needs to be, and this workaround will appear shortly.

4 KEY signal (Signal) the introduction of
Before the introduction of Key signals put subtitles on TV, by contrast, use a car because the letters or the border of a drab color, small letters crumbs looks like or subtitles in a variety of colors of paper to use, there was a limit. Concept for solving this signal is Key.
To put it simply separates the border of the letters while unseen signal signal is Key. Subtitle signals coming from one of the CG equipment made distinguishing "signal" Key to the boundary of characters and character's unique color "signal" Fill two signals ie doengeot. With the introduction of this concept, now able to see a rainbow letters, black letters thin, hair-like character from the TV.

5 Auto Keyer to development
Lettering design and color as the intended subtitles was. The remaining problem is how the letters appeared? Strokes come and fly round and round mosaic-like projections and may occur. Effect devices (DVE) as a digitized equipment used, but also that this effect is dedicating subtitles Auto Keyer equipment to these features the glitz and dizziness TV subtitles led extremes.

6 The emergence of the Linear Key
Will often see if you look closely at the TV, looks translucent screen behind the subtitle subtitles. Jiyo it, especially if the news with subtitles in translucent blue band visible. Be seen to this screen, yet calmly effect. Frills this Linear Key. This Key signal, Fill contrast, differential signals, a combination of the application is made. Linear Key probably not on the subtitles in the future TV terminus seems Not smell or taste or subtitles appeared Unless

TV subtitles will be introduced to help the understanding of the human voice is not clear screen when you need to explain what you mean when you do not know the original. If you think, however, that today's entertainment program in the subtitle, I think I like cheesy halgeot But the story you'll have to be frustrating, as well as emotional damage to young children harms the subtitles that are too awful lot. Connote not accept our fate is, however, a flood of TV subtitles I think I Does not throw off the TV.
