LOLA homepage

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)

Belkin Pro Series High-Integrity VGA/SVGA Monitor Replacement Cable,            
available in 6', 10' 25' and 50' lengths (25' available online for less than    
$15 and 50' available for less than $50)                                               
Designed to support high-resolution imaging and high speed.                     
Constructed of 3 coaxial and 5 twisted-pair cables to minimize cross talk,      
noise, and other interference.                                                  
3 coax conductors for the RGB signal which maximizes color and imaging.         
Double shielding to ensure compliance with FCC requirements.                    
Gold plated copper contacts provide maximum conductivity with no data loss.     
If we are posting information on line about cables, we would also want to       
post information about Hirose and 62-pin d-sub connectors and male/female       
gender. Dan just found a supplier for the D-Sub connector you brought to        
Miami, and I ordered some. We'll know in a week or so if it is what we want.    
And also advice on how to assemble them - those 62 pins are close together!     
Also found an ac adapter substitute for the Toshiba IK-TF5. Toshiba's was       
$125-140, then I found mention of a substitute made by Elmo with the same       
specs and connector for about $60, and then I found a new Elmo on Amazon for

Särestö Academy Handbook for Musical Distance Education

Excellent paper written by Noa Nakai, Technical Planner of the Särestö Academy in Helsinki, Finland. Be sure to check out their list of common problems and their solutions for H.323 video conferencing, as well as a very well documented comparison of many existing video conferencing and streaming technologies.
