Abstract
A computerized method of generating and transmitting a message to a plurality of recipient devices has the steps of obtaining a plurality of recipient multicast identifications (IDs) for the plurality of recipient devices, losslessly encoding the recipient multicast IDs into one or more codewords such that the total length of the one or more codewords is shorter than that of the recipient multicast IDs, generating the message by encapsulating at least the one or more codewords into a payload of the message, and transmitting the generated message to a network. When receiving such as message, a listener device decodes the one or more codewords to determine if it is a recipient.
