The application discloses example methods and apparatuses for map generation and for playing broadcast signals. One example map generation method includes receiving multiple pieces of first information, where each piece of the multiple pieces of first information includes a corresponding positioning location of a corresponding terminal, strength of a broadcast signal modulated at a first modulation frequency and received by the corresponding terminal at the corresponding positioning location, and the first modulation frequency. A broadcast signal strength layer is generated according to the multiple pieces of first information, where the broadcast signal strength layer represents a first coverage range corresponding to a first strength range of a broadcast signal modulated at the first modulation frequency.
