Abstract: PROBLEM TO BE SOLVED: To interrupt an individual program among programs of a specific kinds and/or part of the program by allowing a transmitted source signal, such as a cable television signal, to include the individual program with a transmitted program identifier relating to the specific program. SOLUTION: A hybrid coding signal generator 100 employs ASK coding to modulate a source signal such as a carrier signal, in order to add a transmitted program identifier and/or a transmitted contents identifier. Then the identifier has a sufficient strength for signal transmission and detection. The identifier consists of each functional block or combinations of functional blocks, and the functions represented by the blocks are utilized by using a common hardware or an exclusive hardware with/without hardware that executes the software.
