A method for updating a preset station list and a radio

Abstract

The invention discloses a method for updating preset radio station lists. The method includes that radio station information of various target frequency points in frequency bands can be acquired by the aid of an auxiliary tuner at one step at intervals of preset time, and frequency point information of the target frequency points, which meet station stop conditions, can be stored according to theradio station information, so that the preset radio station lists can be updated. The invention further discloses a radio receiver. The method and the radio receiver have the advantages that the preset radio station lists can be updated by the aid of the method at regular time, the problem that users cannot normally listen to radio stations due to invariable preset radio station lists when an existing radio receiver is shifted can be solved, and accordingly the experience of users can be enhanced; the preset radio station lists can be updated without a main turner of the radio receiver, accordingly, the users can normally listen to radio stations without being affected, and the experience of the users further can be enhanced.

Description

technical field [0001] The invention relates to the field of wireless broadcasting, in particular to a method for updating a preset station list and a radio. Background technique [0002] A radio is a machine that uses electrical energy to convert radio signals and listen to audio signals transmitted by radio stations. With the improvement of people's living standards, the radio is widely installed in the car as a voice entertainment configuration, and it is one of the earliest and most common configurations of the car audio-visual entertainment system. [0003] After the current car radio completes the first search, the preset station list remains unchanged. In order to improve its own coverage as much as possible, each radio station uses multiple transmission towers to transmit radio stations with different frequencies, that is, the frequency point of station A found in place A is a, then the station A received in place B The frequency point of B is b, and the station wi...

AI Technical Summary

Problems solved by technology

Therefore, if the car turns on the car radio in place A and listens to station A, then when the car is driving from place A to place B, the signal of station A will become worse and worse, and even the noise will become more and more serious. Users simply cannot listen to the programs played by Radio A normally, which seriously affects the user experience

Of course, the driver can manually search again to update the preset station list, but this will distract the driver's attention, which not only further affects the driver's experience, but also brings safety hazards to the driver and other users in the car
