主权项

1. A method for low-delay transmission of video frames across a network from a transmitter to a receiver with loss recovery, comprising, at one or more computers coupled to the network:
preparing a first video frame comprising a first source block of source symbols for transmission by encoding a first Forward Erasure Control (FEC) block based on the first source block of source symbols; at the transmitter, transmitting the first FEC block to the receiver; preparing a second video frame comprising a second source block of source symbols for transmission by encoding a second FEC block based on the second source block of source symbols; and at the transmitter, transmitting the second FEC block to the receiver; wherein the first FEC block protects only the first video frame and the second FEC block protects only the second video frame.
