Abstract
There is provided a method and apparatus for sending an encoded signal between a host station and a client station in which the host station encodes data, encodes the error data resulting from that encoding process and generates user data. Thus, the host station generates three types of data and it accords different priorities to those three data types. The first type of data, the encoded original data is accorded the highest priority and is guaranteed delivery to a client station. Thus, a minimum signal quality is guaranteed at the client end. The second type of data, user data, is accorded a lower priority and will be delivered to the client station if there is available bandwidth once the encoded original data has been successfully delivered. The third type of data, encoded error data is accorded the lowest priority and is only delivered to the client station if there is available bandwidth once the encoded original data and the user data have been delivered. A minimum signal quality is ensured with enhancement allowed if possible. The receiving client station(s) may or may not be capable of decoding the error data and the quality at a particular client station will depend on whether it does so or not.
