Abstract

A method of wireless handover in a broadcast network (FIGS. 5 and 8) is disclosed. A wireless receiver (FIG. 4) receives a first signal (N) from a first transmitter (f1). The receiver measures a signal strength (RSSI) of the first signal. The strength of the first signal is compared to a first threshold (T0). The receiver receives a second signal (N+3) from a second transmitter (f3) in response to the step of comparing. The first and the second signals are sent to an application processor (120). The wireless receiver continues to receive the first and second signals until the application processor terminates receiving one of the first and second signals.
