Automated real-time continuous searching of closed-captioned tlevision programming

摘要

A computer system is used to automatically search closed-captioned television for information requested by a user ( ie a keyword). The system may be front ended by an Internet site, where closed-captioned television programming is searched in real time for the requested information. Upon finding the requested information, the user is notified by email, voice mail etc, as to the programme name, broadcast time, broadcast channel. The user may also access a video segment of, or additional textual information from, the identified programme.
