Forward error correction for streaming data
Abstract:
Encoded information corresponding to the encoded source frames and the one or more previous frames is unpackaged from each data packet. Each data packet in the plurality contains encoded information corresponding to a source frame in a sequence encoded at a first bitrate and one or more previous frames in the sequence encoded as forward error correction (FEC) frames at a second bitrate that is equal to or lower than the first bitrate. The encoded source frames are decoded to generate corresponding decoded source frames. Encoded FEC frames that correspond to a given source frame for which encoded information is missing are decoded to generate corresponding decoded FEC frames. A reconstructed frame is generated corresponding to the given source frame using the one or more decoded FEC frames. The decoded source to frames and the reconstructed missing frame are stored in a memory and/or presented with a display.
