  • Heritage (implies the nature)

Why High Technology

  • To preserve the content at its current state.
  • To approach the ideal; to "be there" ourselves.
  • To let our senses, logic and feelings structure our interpretation of events.
  • "How would you like to be the proverbial fly on the wall?", I asked. To which he retorted, "I'd rather be the wall." Giving the notion of walls having ears a whole perspective.
  • Once the barriers start to fall then let the artists, authors and content creators take over the direction.

How?

By removing the walls, digitally.

  • Networks
  • Content manipulation
  • Content association
  • System design and implementation (reality check)

All Digital Rainbows are Bandlimited

Question: Do fewer colours get through a narrow band or do we just have to be clever?
Answer: We just have to be clever, but broadband makes it a bit easier.

Fact: We lose information as soon as we digitise.
Hypothesis: Through creative use of Multimedia we can reconstruct more than what we had by combining sources and gaining different perspectives.

  • Content based searching for text
  • Content based searching for shape, image, object

Horse Racing

Is everywhere. Traditionally Australians love to gamble. The Melbourne Cup is the biggest race of the year. There is a holiday for it in Melbourne. For a fewminutes of the first Tuesday in November, the whole country stops to listen (suposedly). Work place sweeps proliferate. Phar Lap, which won the Melbourne Cup in 1930, is a national hero, and his stuffed body may be seen in the Melbourne museum [and his pickled heart may be admired in the Museum of Australia in Canberra].

Repackaging the Content !

  • MPEG-1 MPEG-2 indexing
  • stills from film
  • mosaicing video
  • melding text and images
  • segmenting video for narrow band transmission
  • restoring raw film in real-time
  • reducing resolution
  • increasing resolution
  • denoising sound and video

Conclusions

  • The systems are keeping up with demand, SGI, Sun, DEC, IBM, Microsoft, Apple and more
  • The networks are not. ATM is still in its infancy. Plan to deliver over narrowband in the near future.
  • Systems should scale as bandwidth broadens
  • Research and development in content access and manipulation is very active.
