Abstract
A method for providing error-resilient video content may include receiving video data reflective of multiple video frames and encoding the video data to generate a plurality of packets. The method may also include transmitting the first group of packets to at least two receivers and receiving feedback information regarding receiving status of respective ones of the plurality of packets, the feedback information being indicative of packets not received correctly. The method may further include examining error indications based on the feedback information and implementing a first error-correction policy if a variation in the error indications among the at least two receivers is below a first error threshold and a second error-correction policy if the variation is above the first error threshold. At least one of the first and second error-correction policies may include transmitting or retransmitting at least one packet using a different coding scheme.
