Claim Text:
1. A method comprising: detecting, by a video decoder, at least one error associated with coded video data sent from a video encoder; determining a round-trip travel time for data communication between the video decoder and the video encoder; determining a last-sent time at which the video decoder last sent the video encoder a previous feedback message indicating a previous error that was detected by the video decoder, wherein the previous error is a different error than the at least one error and is associated with different coded video data than the coded video data; comparing a current time to a sum of the last-sent time and the round-trip travel time; and based on the current time exceeding the sum of the last-sent time and the round trip travel time, sending the video encoder a feedback message indicating the at least one error detected by the video decoder, wherein the feedback message is different than the previous feedback message.
