The Department of Information Engineering of the University of Padova has developed a real-time interactive platform for live teaching, using the most modern multimedia technologies. The aim of the new system is to deliver academic lessons to geographically distributed classrooms, preserving as much as possible the way the teacher communicates and interacts with students in a traditional classroom: delivering lectures, projecting slides, presenting output of program executions, drawing of text and graphics on a blackboard, and interacting with single students.The innovative aspects of the system are: (1) full integration of several communication channels (audio, video and data) into a digital flow over the IP infrastructure, granting high quality communications among a number of remote classrooms, with a bandwidth less than 2 Mbps. (2) fully opensource solution. (3) high quality performance for real-time multimedia presentation. (4) real time interaction between the teacher and the remote students. (5) the absence of a main control center: any classroom can be used for teaching or for attending lessons.

Abstract
The Department of Information Engineering of the University of Padova has developed a real-time interactive platform for live teaching, using the most modern multimedia technologies. The aim of the new system is to deliver academic lessons to geographically distributed classrooms, preserving as much as possible the way the teacher communicates and interacts with students in a traditional classroom: delivering lectures, projecting slides, presenting output of program executions, drawing of text and graphics on a blackboard, and interacting with single students.The innovative aspects of the system are: (1) full integration of several communication channels (audio, video and data) into a digital flow over the IP infrastructure, granting high quality communications among a number of remote classrooms, with a bandwidth less than 2 Mbps. (2) fully opensource solution. (3) high quality performance for real-time multimedia presentation. (4) real time interaction between the teacher and the remote students. (5) the absence of a main control center: any classroom can be used for teaching or for attending lessons.Pubblicazioni consigliate
