Minimizing Delay for Video Conference with Network Coding

Video conference is an attractive and promising application which allows immersive communication and discussion among people at different and distant places. However, its stringent delay and bandwidth requirements limit its scale and spread over current Internet. This paper introduces a network coding algorithm for video conference system to minimize the maximal transmission delay during multicast while retaining high throughput at the same time. The simulation results show that the proposed network coding scheme can reduce delay by 10% to 20% compared with ordinary multicast.
