New systems and methods allow for transmission of multiple types of content protocols over a unidirectional content delivery network, such as a television broadcast. Hardware and / or software used at the network transmission location (such as a television broadcast station) and hardware and / or software located at an endpoint (such as a home television, car infotainment system, or first responder location) allow for a native ATSC 1.0 signal to have embedded within it additional content that is not encoded as ATSC 1.0 content. The non-ATSC 1.0 content can be detected and segregated from ATSC 1.0 content so that the endpoint devices (such as a television receiver) will not attempt to render the non-ATSC 1.0 content (such as, e.g., ATSC 3.0 content or application specific content) as normal ATSC 1.0 programming. Instead, the non-ATSC 1.0 content will be separately decoded, assembled, and processed to allow for multiple types of content to be used and displayed by the endpoint, even though the broadcast signal was transmitted only.

The system does not need priori knowledge of a main user signal and a wireless channel, and can effectively overcome the influence of noise uncertainty. Compared with some spectrum sensing methods based on characteristic value detection, the improved spectrum sensing method has the advantages that the sensing detection probability is higher, the sensing detection performance more excellent than that of a maximum characteristic value-harmonic average (MEHM) method is obtained, and the improved spectrum sensing method is more suitable for judging frequency modulation rebroadcasting signals in a television station; and the stability and the reliability of the television station frequency modulation rebroadcasting system are improved.
