ABSTRACT:
A method and apparatus for detecting errors and improving quality in real-time data transmissions is provided. In one embodiment, the packet header checksum field is turned off to allow uninterrupted transmission of data packet payloads. A checksum added to each independent data segment in the datagram payload permits each data packet to be examined separately, resulting in improved transmission quality.
