Step S30, TV calculates the distance between this TV and described remote controller according to described average signal strength;
Described TV calculates the distance between this TV self and described remote controller according to described average signal strength, and described distance is designated as r.Preferably, described TV is according to described average signal strength P
rthe detailed process calculating the distance r between described remote controller is: described TV is according to formula P
r=P
tthe distortion of/r*n calculates the distance between described remote controller.Described P
tthe average signal strength of the signal of communication of described remote controller is given for described television transmission; Described n is propagation factor, and the environment that its numerical value is propagated by described signal of communication determines.To described formula P
r=P
t/ r*n takes the logarithm, and can obtain
because P
