Embodiment Construction

[0032] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Such as Figure 1-4 Shown, a network synchronous broadcasting method of DMB audio, comprises the following steps:

[0034] S1: upload the audio to the DMB digital multimedia broadcasting server, and the DMB digital multimedia broadcasting server integrates all received data into ETI data;

[0035] S2: The stream pusher parses the ETI data in the DMB digital multimedia broadcasting system server, obtains the program list and sends it to the streaming media server;

[0036] S3: the pusher extracts the audio data in the ETI data;

[0037] S4: The pusher transcodes the audio data into MP3 format;

[0038] S5: The stream pusher encapsulates the transcoded audio data in FLV, and sends them to the streaming media server through different threads and after delay calculation;

[0039] S6: The streaming media server encapsulates the data c...

Abstract

The invention relates to a network synchronous broadcasting method for DMB audio, and the method comprises the following steps: S1, uploading the audio to a DMB digital multimedia broadcasting server,and enabling the DMB digital multimedia broadcasting server to integrate all received data into ETI data; S2, analyzing the ETI data in the DMB digital multimedia broadcasting system server by a stream pusher, obtaining a program list and sending the program list to a streaming media server; S3, extracting audio data in the ETI data by a stream pusher; S4, the push flow device transcodes the audio data into an MP3 format; S5, carrying out FLV packaging on the transcoded audio data by a stream pusher, and sending the audio data to a streaming media server through different threads after delaycalculation; S6, the streaming media server carries out RTMP protocol packaging on the data conforming to the FLV packaging format, subpackages the data and sends the data to the client; And S7, the client receives the program list and the data packet sent by the streaming media server in real time, and then synchronously plays the audio through protocol resolution, decapsulation and decoding.

Description

technical field [0001] The invention belongs to the combination of digital multimedia broadcasting (DMB) public information publishing technology and network live broadcasting technology, and relates to a network synchronous broadcasting method of DMB audio. Background technique [0002] Digital broadcasting is a new generation of broadcasting technology that replaces the traditionally known AM and FM. It transmits digital signals to achieve the purpose of broadcasting and data information transmission. Digital broadcasting includes European standard Digital Audio Broadcasting (DAB) and derived Digital Multimedia Broadcasting (DMB), Chinese standard China Digital Radio (CDR), and American standard HD Radio (HD-Radio). With the development of technology, in addition to only transmitting audio signals in the traditional sense, digital broadcasting can also transmit multimedia signals including audio, video, data, text, graphics, etc., and provide non-real-time push broadcast s...
