Problems solved by technology

Every VoIP terminal must implement the above four aspects. In the existing technical solutions, the data processed by the audio equipment is not distinguished, which makes it difficult to open and close the audio equipment and network ports. Management, and if there is a problem during data transmission, it is not easy to find the cause of the fault

Embodiment Construction

[0032] The main idea of ​​the present invention is to distinguish and package the data processed by the audio equipment according to whether the audio data is collected or played back, and send and receive the packaged data. According to receiving data from the network or sending data to the network, the data received and sent corresponding to the RTP protocol stack are distinguished, encapsulated separately, and the encapsulated data is sent and received.

[0033] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] refer to figure 2 Shown is a flow chart of the audio data transmission method of the present invention. The method is used to transmit audio data between two terminal devices, comprising the following steps:

[0035] Step 201: Separately encapsulate the audio data collected by the terminal device at one end, and deliver the encapsulated audio data to the real-time transport prot...

Abstract

The invention discloses a real-time audio data transmission method which is used for transmitting audio data between two terminal devices. The method of the invention includes that the audio data collected by one terminal device at one end are separately encapsulated; the encapsulated audio data are transmitted to a real-time transmission protocol stack; after being received and processed by the real time transmission protocol stack, the audio data are transmitted to the terminal device at the other end after being separately encapsulated again. The real-time audio data transmission method of the invention can separately process the data transmitted by the audio device and the data received by the audio device, thus better administrating the open and close operation of the audio device and a network interface; furthermore, conveniently finding out the causes of faults when problems occur during the data transmission.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a VoIP (Voice Over IP, voice over IP network) audio data transmission method. Background technique [0002] RTP / RTCP (Realtime Transfer Protocol / Realtime Transfer Control Protocol, Real-time Transport Protocol / Real-time Transmission Control Protocol) is a transmission protocol for multimedia data streams formulated by IETF (Internet Engineering Task Force, Internet Engineering Task Force). RTP is defined to work in one-to-one or one-to-many transmission situations, and its purpose is to provide time information and realize stream synchronization. During the RTP session, each participant periodically sends RTCP packets, and the RTCP packets contain statistical data such as the number of RTP data packets sent, the number of lost RTP data packets, the jitter time, and the delay interval, so as to provide information to the upper layer Applications provide flow control and con...
