We also did an intern project -- Tom's intern who became my = intern after
Tom left (Arjen De Vries) where we did:

1. Converted the caption stream into an sgml = document indexed by time --
so the caption stream came = down in dribs and drabs of the form "turn
background = yellow, foreground white, place this text"... that turned
into the  SGML document, with each element tagged with = time.

2. We then indexed that collection of = SGML documents --   the content
stream was Tom's = ring-buffer of  the CNN live feed (6 hours was what we
stored from memory)
3. We then built a = simple-minded search engine over the SGML documents,
used = the CRL reco engine for getting user queries -- you could also just
type the query at a search box; did the search over the
caption-doc-index, found the time-stamp and played the = video.

Arjen may have published some of = this as his final year Masters project
out of the = University Of Twente -- likely summer 1995.
