Title:
UVC DATA TRANSMISSION-BASED 4G VIDEO AND AUDIO ACQUISITION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/168656
Kind Code:
A1
Abstract:
Disclosed is a UVC data transmission-based 4G video and audio acquisition device, comprising an integrated circuit board, a data input and output interface, a UVC and UART communication system, a video and audio data acquisition module and a 4G communication module, wherein the data input and output interface is connected to the integrated circuit board; both the video and audio data acquisition module and the 4G communication module are embedded into and mounted on the integrated circuit board; and the video and audio data acquisition module is bidirectionally connected to the 4G communication module via the UVC and UART communication system. The UVC data transmission-based 4G video and audio acquisition device is self-driven by a video and audio data acquisition module and is synchronously self-driven by a 4G communication module, and the two modules communicate with each other via a UVC and UART communication system, thereby improving the real-time performance and stability of bidirectional transmission of video and audio digital signals, such that the video and audio data acquisition module can synchronously transmit a data stream to a 4G module while encoding and decoding video and audio data, so as to facilitate background data processing, thereby effectively improving the stability and real-time performance of a product.
