Embodiment Construction

[0054] The main idea of ​​the present invention is to use the audio interface existing in mobile terminals such as mobile phones and communication terminals such as computers to transmit data. We collectively refer to devices with audio interfaces as audio devices. Audio devices include not only mobile terminals (such as mobile phones), communication terminals (such as computers), but also other devices with audio interfaces.

[0055] The audio file stored in the audio device is essentially composed of a bunch of numbers stored in the audio file format. Using audio equipment to transmit data must refer to its audio file format, encode and package the data to be sent into an audio file, and then play it out by the media player of the audio equipment, that is, complete the data transmission. The process of receiving (ie recording) is just the opposite.

[0056] Based on above-mentioned design, the present invention proposes a kind of data transmission method, and this data tra...

Abstract

The invention relates to a data transmission method and a data transmission device. The data transmission method comprises the steps of sending data to be transmitted, wherein the data to be transmitted are treated with primary processing through an audio channel, and / or receiving an audio signal containing data information through the audio channel and recovering data. The data transmission device comprises a first transmission module and / or a second transmission module, wherein the first transmission module is used for sending the data which are to be transmitted and treated with primary processing through the audio channel, and the second transmission data is used for receiving the audio signal containing the data information through the audio channel and recovering the data. According to the data transmission method and the data transmission device, data transmission is achieved through audio interfaces of audio devices such as mobile phones and computers, a novel method to achieve bidirectional data transmission is developed, and requirements of increasing data transmission are met. The data transmission method and the data transmission device lay a foundation for application of other kinds of data transmission based on an audio interface.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method and device. Background technique [0002] At present, mobile terminals such as mobile phones and communication terminals such as computers have been widely used in various aspects of human production and life. Especially in recent years, with the development of network technology, more and more application functions, such as mobile payment functions, access control functions, etc., have been integrated on mobile terminals such as mobile phones. Communication terminals such as computers that can be connected to the network are also playing an increasing role. The data interaction between various devices is becoming more and more frequent, and the demand for data transmission is increasing. At present, data transmission between various devices has methods such as a data cable and a USB interface. However, the number of data interfaces such as data cab...
