Abstract: An exemplary ambient noise filtering method includes: sampling ambient noise signals to obtain multiple groups of sampled signals; analyzing each group of the sampled signals in each sampling period to determine ambient noise frequency band(s) in each sampling period, wherein the ambient noise frequency band is a frequency band where the ambient noise distributes; determining main noise frequency band(s) by statistically analyzing all the ambient noise frequency bands, wherein the main noise frequency band is a frequency band where the ambient noise concentrates and mainly distributes; and filtering the ambient noise out of signals generated during a communication by filtering the determined main noise frequency band(s) if the main noise frequency band(s) does not have a same range as that of a speech frequency band. Related exemplary mobile phone performing the method is also provided.

Abstract: A broadcast playback system comprises a computer and a broadcast playback apparatus being connected to each other via a serial bus module. The computer loads predetermined control codes stored in the broadcast playback apparatus, performs the predetermined control codes to display a control menu.
