Receiver system capable of locking the same broadcast channel based on different emission frequencies

Abstract

The invention discloses a receiver system capable of locking the same broadcast channel based on different emission frequencies. The receiver system comprises a geographical location information reception module, a broadcast program information database module, a wireless simulation broadcasting receiver module, a micro central information control module and a display and operation interface module, wherein the geographical location information reception module, the broadcast program information database module, the wireless simulation broadcasting receiver module and the display and operation interface module are respectively connected with the micro central information control module. The receiver system is applicable to radio station programs containing AM broadcast frequencies and FM broadcast frequencies, only technology reconstruction is necessary for a receiver end, the popularization application time is quite shorter than the popularization application time of the RDS technology, and application cost is further quite lower than that of RDS system application.

Description

technical field [0001] The invention relates to the field of wireless analog broadcast mobile reception, in particular to a receiver system capable of locking the same broadcast channel based on different transmission frequencies. Background technique [0002] At present, the composition of my country's wireless analog signal broadcast coverage network, the same broadcast program, except for some of which use the single frequency network with multiple transmission points at the same frequency to complete the coverage, most of them use the multi-frequency network to achieve large-scale coverage. In a multi-frequency network, each transmitting radio point covers a certain area. When moving to receive a certain radio program, if there is crossing from one frequency point coverage area to another frequency point coverage area, frequency switching is required to maintain continuous reception of the radio program. But for the listeners, if they are in an unfamiliar place, it is e...

Problems solved by technology

There is no market environment for promoting RDS in our country, so it is difficult to promote and apply RDS in broadcasting at present, so that most transmitters in the market do not have RDS broadcasting functions, and most civilian receivers cannot receive RDS data information. Certain brands of mobile phones have the ability to receive RDS broadcasts

Moreover, the timely adoption of the RDS system broadcast can only solve the radio program reception of the radio broadcast in the FM mode, but cannot solve the technical problems of the radio program reception of the radio broadcast in the AM mode
