sentences:  This allows the codec to (a) detect errors in the stream and (b) potentially correct, or at least conceal, the error during playback.These codecs are ideal partners for UDP-Lite, since they are designed to work with a damaged data stream, and it is better for these codecs to receive perhaps 200 bytes where a few bits are damaged rather than have to conceal the loss of an entire packet that was discarded due to a bad checksum.The application layer understands the significance of the data, where the transport only sees UDP packets.
