Sign-language media

Sign-language media are media based on a media system for sign languages. Interfaces in sign-language media are built on the complex grammar structure of sign languages. Generally media are built for oral languages or written languages, and are often not compatible with sign languages.

Sign-language media have specific characteristics:
 * Sound is absent, or on very low frequencies (bass).
 * No, or very little, text is used.
 * A specific camera frame for close-ups.
