Abstract: An example method to decode an error-correcting code includes receiving a tuple including a seed and a coded packet over a communication channel, and based on the seed, reconstructing a set of pseudorandom coefficients used by an encoder to create the coded packet. The method also includes entering the set of pseudorandom coefficients and the coded packet in a decoding matrix and reducing the decoding matrix to a row echelon form. After reducing the decoding matrix to a row echelon form, the method further includes determining if the decoding matrix is decodable up to a number of rows, reducing the decoding matrix up to the number of rows by backward substitution so a part of the first matrix becomes an identity matrix and a corresponding part of the second matrix comprise source packets, and extracting the source packets from the padded packets.

Abstract: A method is provided to transmit an error-correcting code. The method includes receiving a source packet, advancing a sliding encoder window after receiving the source packet, and generating coded packets by, when the padded packet is encoded for a first time, encoding the source packet alone, and, when the source packet is encoded for a number of times after the first time, encoding the source packet with older source packets in the sliding window.

Abstract: An example method to perform rate control in a parallel encoding system including a plurality of parallel encoders is disclosed. The method may comprise determining a quantization parameter for one of the plurality of parallel encoders based on a measure of parallelism of the plurality of parallel encoders. The method may further comprise providing the quantization parameter to the one of the plurality of parallel encoders to encode a chunk of a video sequence to generate an encoded chunk based on the quantization parameter.
