Abstract
A network-adaptive error recovery method for real-time video transmission based on sending repair frames preemptively with a frequency that is based on observed run-length of good frames and round trip time.
Claims20
An apparatus comprising:
- a machine-implemented video sender configured to:
- receive first information representing an error rate;
- receive second information representing a round trip time (RTT) between the sender and a receiver of video;
- and
- based on the first and second informations, determining a frequency with which to transmit video repair data.

A method comprising:
- providing network-adaptive error recovery for real-time video transmission based on:
- sending repair frames preemptively with a frequency,
- the frequency being based on at least one run-length of good frames (RLG) and a round trip time (RTT).
Method, comprising:
- establishing a threshold based on round trip time (RTT) associated with a sender of video and a receiver of the video;
- comparing indicia of error rate in the video as received by the receiver to the threshold;
- and
- based on the comparing act, deciding whether to change a frequency with which video repair information is preemptively sent from the sender to the receiver.
