REAL TIME IP VIDEO TRANSMISSION WITH HIGH RESILIENCE TO NETWORK ERRORS

摘要

A method and system related to video transmission to increase resiliency to network errors, such as packet loss. Packet loss can lead to low quality or broken audio, pixilation, image freeze, and other distortions of a video signal. The system and method utilizes packet retransmission and FEC in combination to increase error recovery. Further, the system and method takes into account unique data source characteristics in order increase resilience to network error while minimizing overhead. Finally, the system and method takes into account network conditions, especially in networks with heterogeneous conditions, by separating uplinks and downlinks and adjusting to each individual link in order to provide optimal protection for each link.
