Closed Caption (CC) consists in converting the audiovisual contents into text. It is a tool that allows elderly people or with hearing impairment to access the content broadcasted on television or digital platforms. This service can be enabled by the viewer and it will appear on his or her screen.
This service is done through specialized equipment which subtitles all dialogues and describes important sounds. It is very useful in noisy places such as public transportation, airports, restaurants, banks and similar venues.
Hidden subtitling is done for live or recorded content and it is used in television or digital platforms. Subtitles can appear in Roll Up
or Pop On
At the moment of live broadcasting, a trained team specialized in voice recognition dictates the audio to convert it into text, so that the subtitling appears on the screen.
For prerecorded programs such as: movies, series, documentaries, animation and others. Transcription, time synchronization, sound description and music are made, and the characters (who spoke, tone of voice, and accents) are specified.
By doing so, television broadcasters can fulfill the CEA 608 and CEA708 norms issued by the Federal Institute of Telecommunications (IFT, for acronym in Spanish).
