The LAVID Digital Video Applications Lab at the Federal University of Paraiba in Brazil has been researching and developing digital video applications for 15 years. It has about 60 researchers working on networks, multimedia, games, embedded systems and digital television. Some of its projects include developing the Ginga middleware adopted as the Brazilian digital TV standard and an overlay network of videoconference and video servers. It is now working on a telemedicine tool called Arthron to transmit surgeries for medical education purposes and has conducted pilots transmitting hernia surgeries between operating rooms and telemedicine rooms.
