Abstract:
A current frame in a sequence and one or more previous frames in the sequence may be encoded and decoded with forward error correction (FEC). The current frame is encoded at a first bitrate to generate one or more encoded source frames and the one or more previous frames are encoded at an equal or lower second bitrate to generate one or more encoded FEC frames. The encoded source frame(s) and FEC frame(s) are packetized into one or more data packets, which are stored in a memory or transmitted over a data network. The encoded source frame information and previous frame information is unpackaged from the packets and the encoded source frames are decoded. If given source frame of the sequence is missing, one or more encoded FEC frames that correspond to the given source frame are identified from among the data packets and decoded and used to reconstruct the given frame.
