1. A method of individualizing a general broadcast signal, comprising:
- combining a user identifier and a message to form a first message layer signal;
encoding the first message layer signal;
combining a first source identifier with the encoded first message layer signal to form a second message layer signal; and
encoding the second message layer signal.
