Abstract
An apparatus, method and computer program product for generating a hypermedia document from a transcript of a closed-captioned television program using parallel text alignment. The method includes the steps of receiving the closed-captioned text stream with its associated frame counts and the transcript, aligning the text of closed-captioned text stream and the transcript; transferring the frame counts from the closed-captioned text stream to the transcript; extracting video frames from the television program; and linking the frames to the frame-referenced transcript using the frame counts to produce the hypermedia document. The present invention produces other types of hypermedia products as well.

An apparatus for producing an enriched time-referenced text stream using a time-referenced text stream and an enriched text stream, comprising:
- means for receiving the time-referenced text stream and the enriched text stream;
- means for aligning the text of the enriched text stream with the text of the time-referenced text stream;
- and
- means for transferring time references from the time-referenced text stream to the enriched text stream based on the alignment to produce an enriched time-referenced text stream;
- wherein the time-referenced text stream is a closed-captioned text stream associated with a media stream, and wherein the enriched text stream is a transcript associated with the media stream.
A method for producing an enriched time-referenced text stream using a time-referenced text stream and an enriched text stream, comprising the steps of:
- receiving the time-referenced text stream and the enriched text stream;
- aligning the text of the enriched text stream with the text of the time-referenced text stream;
- and
- transferring time references from the time-referenced text stream to the enriched text stream based on the alignment to produce an enriched time-referenced text stream;
- wherein the time-referenced text stream is a closed-captioned text stream associated with a media stream, and wherein the enriched text stream is a transcript associated with the media stream.
A computer program product for producing an enriched time-referenced text stream using a time-referenced text stream and an enriched text stream, said computer program product comprising a computer usable medium having computer readable program code means embodied in said medium, said computer readable program code means comprising:
- computer readable program code means for causing a computer to receive the time-referenced text stream and the enriched text stream;
- computer readable program code means for causing a computer to align the text of the enriched text stream with the text of the time-referenced text stream;
- and
- computer readable program code means for causing a computer to transfer time references from the time-referenced text stream to the enriched text stream based on the alignment to produce an enriched time-referenced text stream;
- wherein the time-referenced text stream is a closed-captioned text stream associated with a media stream, and wherein the enriched text stream is a transcript associated with the media stream.
