Applications
LOLA
The LOLA technology is a low latency, audio and videoconferencing technology that enables real-time, simultaneous, live musical performances across long distances over advanced research and education networks. LOLA was developed by Conservatorio G. Tartini in Trieste, Italy, and the Italian Research & Education Network, GARR. Also, Stanford University's Center for Computer Research in Music and Acoustics is involved in development and research on human interaction and latency.

Costs as compiled by Paul Bauer of Northern Illinois University:
Bitflow ALT-PCE-AN1 Analog Frame Grabber = $575
RME Hammerfall HDSP 9632 PCI Audio Interface $550
Industrial Camera - B/W - (suggested model) Sony XCHR50 = $575
OR Color - (suggested model) Hitachi KP-FD30 (plus AC adapter) = $1,350
Custom Camera Cable - Possible to self-construct 50 foot cable for less than $100 from VGA cable and appropriate connectors.
So that is a $1,800 - $2,500 add-on to a computer to be LOLA capable. Then at NIU we added the following optional equipment.
(highly recommended add-on vari-focal lens - Sony XCHR50 accepts C-mount lens. We obtained a Tamron 12VM412ASIR lens = $100)
(Hitachi accepts CS mount - NIU obtained Fujinon FUDV10X7B2 DV10x7B-2 1/2" 7-70mm Lens = $100)
(To allow flexibility, we also got the following RME BO9632XLRMKH balanced analog breakout cable for the HDSP9632 system = $100)
