1. A control method of a receiver, comprising:
when the receiver enters a sleep/standby mode, continually detecting an auxiliary signal from an auxiliary channel to generate a detection result; and
if the detection result indicates that the auxiliary signal has a preamble or a specific pattern following the preamble, generating a wake-up control signal to start to wake up the receiver before successfully receiving an entire wake-up command following the preamble, wherein the specific pattern is only part of the wake-up command.
