Abstract

The invention provides a method and device for transmitting audio data in a target area, and the method comprises the steps: determining a to-be-transmitted data packet which at least comprises first data used as a digital video display signal, second data used as a USB data signal, and third data used as an analog audio signal, and the third data comprises left channel analog audio data and right channel analog audio data; sending a data packet to a receiving end through the Type-C wire harness, so that the receiving end plays the left channel analog audio data and the right channel analog audio data locally or sends the left channel analog audio data and the right channel analog audio data outwards based on an FM radio frequency method in the target area while displaying the digital video display signal, wherein the Type-C wire harness is provided with a plurality of preset interfaces, and the plurality of preset interfaces at least comprise a first data interface used for transmitting first data, a second data interface used for transmitting second data and a third data interface used for transmitting third data. According to the method, USB data signals, digital video display signals and analog audio signals can be transmitted 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...
