UDP-Lite
From VideoLAN Wiki
UDP Lite is a standardized IP transport protocol (RFC 3828) for error-prone network environments. It offers to applications such as streaming media to use the 'good parts' of a partially corrupted packet. Normally the whole UDP packet is discarded when the checksum does not pass. UDP Lite makes it possible to reuse useful information in such cases by limiting the scope of the checksum length. This can improve audio and video quality.
