Abstract
Methods and apparatuses are provided for transmitters and receivers for conveying and retrieving important system information carried in a multi-carrier modulation system for which the data stream is organized in multiple physical layer pipes (PLP). This is particularly important when broadcasters share the same physical channel. In one aspect of the present principles this is accomplished by assigning a PLP as a system PLP. The system PLP will carry information such as the mapping between a broadcaster and its PLPs and special messages like the Emergency Alert System and Amber Alert messages. In another aspect of the present principles, this information is carried in signaling data of the signal, instead of a PLP. In yet another aspect of the present principles, this is accomplished by a signaling parameter, which identifies the broadcaster associated with each PLP.
