Abstract
A multi-level encoded signal monitoring system and a universal broadcast code are provided. A plurality of encoders are provided for encoding a predetermined program source signal. The program source signal has a plurality of sequential segments. Each encoder is arranged for selectively encoding information on uniquely specified segments. A plurality of unique source information message data are selectively encoded on the uniquely specified segments to define the universal broadcast code with each unique encoded source information message data being representative of a level of distribution of the program signal. The predetermined program source signal is received and the encoded information on selected specified segments is decoded.
