Embodiment Construction

[0042] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:

[0043] refer to figure 1 , the audio broadcasting system of the present invention includes an audio broadcasting sending device 1 and an audio broadcasting receiving device 2, and the transmission channel of the audio broadcasting system adopts FM modulation. Wherein, the audio broadcasting sending device 1 includes: an audio playing front end 11 for generating audio broadcasting programs. The FM transmitter 12 is used to perform FM modulation on the audio broadcast program, and insert a 15Hz sinusoidal signal between every two adjacent program contents of the audio broadcast program during the modulation process as a program identification mark, and transfer the modulated The audio broadcast signal is sent to the FM transmitting antenna 13 (the conventional audio range is 20Hz---30KHz, and the human ear is imperceptible to audio signals lower than ...

Abstract

The invention discloses an audio broadcast system, a receiving device thereof and an audio receiving processing method. The system comprises an audio broadcast transmitting device and an audio broadcast receiving device, wherein the audio broadcast transmitting device of a audio broadcast system inserts a program identifier between every two adjacent program contents of an audio broadcast program to distinguish each program content of the audio broadcast program; thus, the audio broadcast receiving device of the audio broadcast system distinguishes the program contents of the audio broadcast program by identifying the program identifier during broadcast receiving; moreover, the audio broadcast receiving device also compresses each program content of the audio broadcast program into a corresponding MP3 format file according to the program identifier for caching; if a user needs to save the file, the audio broadcast receiving device stores the MP3 format file; otherwise, the receiving device automatically updates the MP3 f format file. Therefore, the user can selectively save audio broadcast programs.

Description

technical field [0001] The present invention relates to the technical field of audio broadcasting signal processing, in particular to an audio broadcasting system, a receiving device thereof, and an audio receiving and processing method. Background technique [0002] In today's society, listening to audio broadcasting is one of the important ways for people to entertain and obtain information. However, when people listen to audio broadcasting programs online, they sometimes wish to selectively save some programs (such as saving a song just heard), and because the conventional audio broadcasting system (such as FM broadcasting), only the audio signal is modulated on the carrier wave. The audio broadcast receiving device can only record according to the time period when saving the audio broadcast program, and the user cannot selectively save the audio broadcast program. Contents of the invention [0003] The purpose of the present invention is to provide an audio broadcasti...
