Audio data transmission method and device in target area

Abstract

The present invention provides a method and device for transmitting audio data in a target area. The method includes: determining a data packet to be sent, and the data packet at least includes: first data used as a digital video display signal, second data used as a USB data signal data and the third data used as an analog audio signal, and the third data includes left channel analog audio data and right channel analog audio data; send data packets to the receiving end through the Type‑C harness, so that the receiving end displays digital While displaying the video signal, the analog audio data of the left channel and the analog audio data of the right channel are played locally in the target area or sent out based on the FM radio frequency method; among them, the Type-C wiring harness has multiple preset interfaces, and multiple The preset interface at least includes: a first data interface for transmitting first data, a second data interface for transmitting second data, and a third data interface for transmitting third data. This method can transmit USB data signal, digital video display signal and analog audio signal at the same time.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a method and device for transmitting audio data in a target area. Background technique [0002] In multimedia transmission applications, it is sometimes necessary to simultaneously transmit digital display signals, USB data signals and audio signals. Audio signals are usually divided into two categories: digital audio signals and analog audio signals. For digital audio signals, it can be transmitted through the USB data channel, specifically the USB data channel to transmit audio auio, for example, by mounting the USB Codec on the USB2. Simultaneous transmission of digital display signals, and because they are both digital signals, there will be no noise interference between them. [0003] However, due to the limitations of the existing technology, the digital display signal and the analog audio signal cannot be transmitted at the same time, and usually only one of th...

Problems solved by technology

[0005] The present invention provides a method and device for transmitting audio data in a target area, which is used to overcome the problem that the digital display signal and the analog audio signal cannot be transmitted at the same time in the prior art and the digital display signal will interfere with the analog audio signal if the simultaneous interpretation is rigid. The defect of noise interference caused by transmission can realize the effect of effective simultaneous interpretation of digital display signal, USB data signal and audio signal
