Methods and apparatus for the provision of user selected advanced closed captions
Abstract
User customizable advanced closed caption capabilities are provided using closed caption information, such as that described in the Electronic Industries Association (EIA) Television Data Systems Subcommittee standards, EIA-608 or EIA-708. The invention allows the user to override the closed caption presentation format as selected by the originator (e.g., programmer or broadcaster), in order to select alternate presentation attributes based on the user's preference. The invention may also be implemented to customize other forms of text information (e.g., subtitles.). The invention also allows for storage and subsequent retrieval and review of text included within the closed caption information, which text serves as a transcript of the program. The methods and apparatus provided are independent of the type of delivery network, content format, and receiver type. In an example embodiment, closed caption information is extracted (e.g., by a closed caption processor 20) from a television signal 10, which television signal 10 also contains corresponding audiovisual programming. The processor 20 determines whether one or more user selected attributes 12 have been set. At least one user selected attribute 12 is applied to at least a portion of the closed caption information (e.g., via a closed caption driver 30). The closed caption information is displayed (e.g., via a display driver 40 and graphics processor 45) on a display device 50 (e.g., a television screen) in accordance with the user selected attributes 12 via a graphical overlay on top of the audiovisual programming. In this manner, user selected advanced closed caption features can be provided using existing closed caption information contained in the television signal.
