Developments in Networked Distributed Computing and Delivery of Australia's Heritage Electronically
- Networked (implies connectedness)
- Distributed (implies geographic separation)
- Delivery (implies content to consumer)
- 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.

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.
