Frequency modulation broadcast receiving method for vehicle end

Abstract

A frequency modulation broadcast receiving method for vehicle end comprises determining a geographical position of the vehicle end to determine a current location area of the vehicle end; acquiring, based on the current location area, a local broadcasting radio station list which is corresponding to the current location area and is stored in the vehicle end; if the local broadcasting radio station list is not acquired in the vehicle end, automatically acquiring the local broadcasting radio station list according to radio station radio wave of the current local area and storing the local broadcasting radio station list, and when the vehicle end arrives at the current local area again, retrieving the stored local broadcasting radio station list; and based on the local broadcasting radio station list, determining which radio station is to be selected and playing the selected radio station. When a vehicle end enters a new area, the local broadcasting radio station list that is corresponding to the current location area of the vehicle end and is stored in the vehicle end is retrieved by the vehicle end, and thus a broadcasting radio station searching process is saved, a radio station is selected and determined in a relatively short period, and user experience of the vehicle end is improved.

Description

technical field [0001] The invention relates to FM broadcast technology, in particular to a method for receiving FM broadcast at a vehicle terminal. Background technique [0002] The radio is an essential function of modern in-vehicle technology. In the high-speed pace of life, the radio not only helps to relax the user's driving mood, but also helps the user to obtain the latest information. According to statistics, the radio is the most frequently used function on the vehicle side. [0003] Radios are mainly frequency modulation (FM) and amplitude modulation (AM) systems, which receive different stations based on the principle of short-wave communication stations. As a type of radio broadcasting, FM broadcasting transmits program content by means of wireless transmission. Unlike AM broadcasting, FM broadcasting transmits audio signals in the form of frequency modulation. The carrier wave of FM wave changes on both sides of the carrier center frequency (the center freque...

Problems solved by technology

[0006] The present invention provides a method for receiving FM radio at the vehicle-mounted terminal. When the vehicle-mounted terminal arrives in a new city, it obtains a list of local broadcasting stations in the newly arrived city, and based on the list of local broadcasting stations, determines the selected station that needs to be played, and listens to the local broadcasting station. Radio station, so as to solve the customer experience defect of listening to radio stations on the car side caused by the fact that the user needs to spend a lot of time to search for radio stations in the area every time the car terminal arrives in a new area, and determine the radio station to listen to
