Title-Vision

Title-Vision is a type of eyewear, resembling sunglasses. These glasses are worn in the movie theater, in order to read the subtitles.

Have you ever experienced being in another country (some non-English speaking country, like Germany, for instance) and found out that even if you would want to watch a movie in their theaters, you wouldn't understand it because the dialogue is in German, which you don't understand? You wouldn't even be able to watch Hollywood movies showing there because they have also been dubbed in German. And there are no subtitles.

This will no longer happen once the celluloid film format retires, and the digital film format becomes the world standard.

When a film is shown in digital format, other encrypted layers can be embedded in the digital image. Thus, the subtitles can be hidden in a layer of text, and this layer would be invisible to the naked eye.

But, when you wear Title-Vision glasses, the lens on the glasses will be able to decode the subtitle layer. Thus, you would be able to read the subtitles only if you are wearing Title-Vision glasses. A person sitting next to you in the theater who is not wearing any Title-Vision glasses would not be able to read, much less see, the subtitles at all.

Title-Vision glasses are designed to decode subtitles in different languages. Different languages would have different encryption codes, and to view the subtitles in Mandarin, for example, one must have the Title-Vision glasses capable of decoding Mandarin. So let's say you are trying to watch a German film, and that German film has three subtitle layers encoded in it (for example, English, Spanish, and French), you would need the corresponding lenses to view the subtitles. And even if you have the Title-Vision Mandarin glasses, you still wouldn't be able to read anything, because there is no Mandarin subtitle layer embedded in the image.

Just as it is possible to have several languages embedded in a single picture, it is also possible to have a pair of glasses capable of decoding several subtitles.

This is for the people who love to read subtitles while retaining the original dialogue, as against those who prefer the "dubbed and un-subtitled" variety.
