Abstract

This invention provides for enhancements to the current closed caption capabilities available on most televisions. The first enhancement helps a viewer to know which speaker to associate closed caption text with. This is accomplished by assigning a color to a speaker. The closed caption text is then shown in the color with which a given speaker is associated. This is implemented by embedding information in the closed caption signal and by enhancing the set-top box or television to perform this function. Voice recognition technology identifies different speakers in a television show and assigns a color to closed caption text based on who is currently speaking. In the case of a set-top box with an electronic program guide, the ending time of a show resets voice recognition information after the show has ended. While in some cases the display attributes associated with a distinguishable voice could be assigned on a first come, first "observed basis", if a user desires that voices be flagged consistently from show to show, the set-top box could save voice recognition data. Once particular speakers are identified, editing out of speakers can be accomplished. A user can edit out a speaker's closed caption comments while still seeing the rest.

Expanding the capabilities of closed caption

This invention provides for enhancements to the current closed caption capabilities available on most televisions.

The first enhancement helps a viewer to know which speaker to associate closed caption text with. This is accomplished by assigning a color to a speaker. The closed caption text is then shown in the color with which a given speaker is associated. This is implemented by embedding information in the closed caption signal and by enhancing the set-top box or television to perform this function.

Voice recognition technology identifies different speakers in a television show and assigns a color to closed caption text based on who is currently speaking. In the case of a set-top box with an electronic program guide, the ending time of a show resets voice recognition information after the show has ended. While in some cases the display attributes associated with a distinguishable voice could be assigned on a first come, first "observed basis", if a user desires that voices be flagged consistently from show to show, the set-top box could save voice recognition data.

Once particular speakers are identified, editing out of speakers can be accomplished. A user can edit out a speaker's closed caption comments while still seeing the rest.

In addition to identifying particular speakers, emotion can also be detected and the closed caption text modifed to show this. This could be done by analyzing the spoken words and deter...
