Embodiment Construction

[0030] The present invention will be further elaborated below with reference to the accompanying drawings.

[0031] see figure 1 According to an audio interface-based data transmission method provided by the present invention, the decoded signal is sent through the audio interface, and / or the encoded second audio signal is sent through the audio interface.

[0032] Further, the decoding process includes:

[0033] Step 101, performing audio processing on a received first audio signal to obtain a first square wave signal.

[0034] Step 102: Sampling and sending the first square wave signal at a sampling rate to obtain a first discrete signal.

[0035] Step 103, detect the information header and synchronous character of the first discrete signal; if the information header and synchronous character are detected, decode the information body of the first discrete signal according to the audio decoding protocol to obtain a decoded signal.

[0036] Encoding processing includes:

...

Abstract

The invention relates to a data transmission method and device based on an audio interface. The data transmission method sends a decoding signal after decoding processing through an audio interface, and / or sends a second audio signal after coding processing through the audio interface. The decoding processing comprises: performing audio processing on a received first audio signal to obtain a first square wave signal; sampling and sending the first square wave signal in a sampling rate to obtain a first discrete signal; and detecting and decoding the first discrete signal to obtain a decoding signal. The coding processing comprises: decomposing and coding the information to be coded to obtain a second discrete signal; sampling and sending the second discrete signal in the sampling rate to obtain a second square wave signal; and performing audio processing on the second square wave signal to obtain a second audio signal. The data transmission device comprises an audio processing unit, a signal sampling sending and receiving unit, an audio decoding unit and an audio coding unit. The data transmission method and device improve reliability and reduce cost.
