Problems solved by technology

[0016] (1) The FM radio application is a one-way transmission mechanism and lacks a feedback channel, making it impossible to directly interact between the audience and the radio station, and between the audience and the audience. Third-party tools are required, and the process is cumbersome and the degree of automation is low
[0017] (2) Because FM radio needs to use third-party tools as an intermediary, the timeliness of related interactions is very low, which is not conducive to the use of scenarios with high real-time requirements
[0018] Based on the above examples, the information interaction of FM broadcasting application scenarios in the current technology is cumbersome and inefficient (needs a lot of manual intervention and cannot be automated), and the real-time performance is not high (cannot meet real-time or quasi-real-time requirements). There are new methods and technologies to solve

Embodiment 1

[0114] 1 [Embodiment 1] The radio station automatically selects songs

[0115] In this embodiment, the FM radio station deploys an automatic song-ordering server, and the user initiates song-ordering to the radio station through a mobile phone or a vehicle-mounted intelligent terminal, with a song-ordering testimonial attached; after the server obtains the song-ordering request, it extracts the corresponding song from the music storehouse, After the song is multiplexed through the FM main carrier and the song-ordered testimonials are sent out in the form of FM sub-carrier / sub-carrier; all receivers listening to the FM radio station can hear the song ordered by the song-orderer from the terminal, and also from the terminal Extract the postscript from the wireless electronic carrier / subcarrier frequency for display or broadcast.

[0116] The deployment architecture and process of this embodiment are represented as Figure 5 .

[0117] The workflow is as follows:

Embodiment 2

[0140] 2 [Example 2] Real-time reminder of abnormal vehicle condition information

[0141] In this embodiment, the real-time information receiving entity is deployed on a mobile vehicle, such as a car. When pedestrians are driving on the road, they can observe the conditions of other vehicles within a range of several meters to tens of meters. When they find that there is a problem with the surrounding vehicle conditions, it is necessary to remind the other driver to pay attention. However, on the highway, traditional methods such as flashing lights and horns cannot be used to effectively remind the other party, and if you drive in parallel with the other party's vehicle and open the window to remind, the danger is too high and accidents are prone to occur. Another scenario is that pedestrians on the side of the road sometimes observe abnormalities in passing vehicles, and there is usually no effective way to notify the driver at this time. One way is to let the vehicle manag...

Embodiment 3

[0160] 3 [Example 3] Real-time sharing of road condition information

[0161] In this embodiment, the real-time information receiving entity is also deployed on a mobile vehicle, such as a car. When driving on the road, pedestrians hope to know the traffic conditions of the route in a timely and comprehensive manner. However, the traffic information obtained through traditional radio stations or map navigation apps usually has a large delay (half an hour to several hours). This may cause misjudgment of road conditions and routes. In order to solve this kind of problem, the real-time information notification method of this patent can be adopted, and multiple listeners can release real-time road conditions, and directly reach other vehicles in the same industry through FM broadcasting, greatly shortening the information turnaround time, and providing effective and real-time road conditions for the vehicles behind guide.

Abstract

The invention discloses a method, apparatus and system for realizing real-time information interaction of frequency modulation broadcasting. The method comprises the following steps: step 1: an information providing terminal (also called a real-time information providing entity) sends real-time information to a server (also called a real-time information transfer entity); step 2: the server processes the received real-time information; the processing comprises performing frequency modulation on the real-time information; step 3: the server broadcasts the modulated real-time information through a frequency modulation channel; and step 4: an information receiving terminal (also called a real-time information receiving entity) receives and processes the real-time information; the information receiving terminal decodes the modulated real-time information, obtains the decoded real-time information and displays or broadcasts the real-time information. By adoption of the method, apparatus and system disclosed by the invention, bidirectional information interaction of the terminal and the broadcasting server can be realized to transmit the real-time information.

Description

technical field [0001] The invention relates to a method, device and system for realizing real-time information interaction of FM broadcasting. Background technique [0002] FM stereo broadcast refers to the broadcast technology that transmits sound information through multiple sound information channels, so that the spatial sound image can be presented when restored. [0003] Commonly used for the two-channel. Due to the wide bandwidth of the stereo signal and high signal quality requirements, it is usually transmitted by FM. It is also necessary to configure two channels when listening, and even use surround sound speakers to obtain stereo effects with spatial layers. [0004] Method to realize: [0005] FM stereo broadcast first encodes two audio frequency (left and right channel) signals to obtain a set of low-frequency composite stereo signals, and then FM transmits the high-frequency carrier. [0006] broadcast system [0007] FM stereo broadcasting is divided int...
