Abstract: An error resilience method comprising: using a computer, creating and storing, in computer memory, one or more FEC filter tables for use by the FEC filter for selectively forwarding a FEC packet; selectively forwarding a request for the FEC packet through a FEC filter based on the FEC table and a dynamic packet loss level at a receiver; limiting a re-transmission request for a particular packet through the FEC filter based on a number of re-transmission requests for the particular packet; and selectively skipping a key frame request based on a number of key frame requests received from a plurality receiver devices, wherein the method is performed by one or more special-purpose computing devices.
