An Approach to Real-Time Voice Communications over the Internet
نویسندگان
چکیده
This paper describes the approach taken for the development of an Internet telephone software system which functions like a conventional telephone to support real-time voice communications over the Internet. The system allows voice to be captured and digitised at the source machine. Using Internet as the transmission medium, these voice samples are then transmitted to the destination machine where they are received and played back in real-time on its audio device. The system has been implemented on Unix-based Sun Sparc workstations at the School of Applied Science, Nanyang Technological University.
