X-Message-Number: 21585 From: Date: Sat, 12 Apr 2003 08:11:11 EDT Subject: WEB HDTV --part1_63.1b539f04.2bc95c5f_boundary Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit Seen an information on ZD-Net about a Japan concert on April 16 distributed in HDTV with a picture quality superior to DVD. It will be a test bed for that new technology. I think it is interesting because that will push the ADSL bandwidth, disk capacity and processing power up. All of that is in dire needs for distributed computing for a brain reader. If building back a picture in a first generation MRI brain scan asks for 10^21 floating-point operations and there are 100,000 processors, then each must crush 10^16 fpo. Assume a computing time in the 100,000 seconds range, that ask for a processing power near 10^11 operations per second. This is 3 orders of magnitude beyond the present generation. Either we must wait for 15 years or look at some "super-Moore" evolution. HDTV could be a driver for that evolution. Y.
