Audio and video configuration and playing solution based on USB AOA protocol

Abstract

The invention discloses an audio and video configuration and playing solution based on a USB AOA protocol. The audio and video configuration and playing solution comprises a main control chip, a wifiPHY module, an audio coding module, a video decoding module, an HDMI output interface and an audio acquisition module. The Wifi PHY module is connected with the main control chip, and the main controlchip is connected with the audio decoding module, the video decoding module and the audio coding module; the audio coding module is connected with the audio acquisition module; the audio coding module is connected with the USB interface, the wifi module and the 4G module; wherein the video decoding module and the audio decoding module are connected with the HDMI output interface and the USB interface, and the HDMI directly outputs audios and videos and interacts with the USB through an android AOA protocol to distribute the videos. The invention provides a solution of a wireless image transmission ground terminal, which supports multipath videos and bidirectional audios, and supports USB / wifi / 4G distribution and configuration.

Description

technical field [0001] The invention belongs to the technical field of audio and video playback, in particular to an audio and video configuration and playback solution based on the USB AOA protocol. Background technique [0002] In high-risk environments such as forest fire monitoring, mining, unmanned ships, anti-terrorist combat or exercises, it is often necessary to deal with various emergencies. At this time, it is even more necessary to use modern scientific and technological means to achieve high-speed collaboration, and to display the real-time on-site environment on various display devices and separate receiving devices for multiple people to achieve the purpose of collaboration. [0003] In order to achieve the above goals and better deal with unmanned sites, a wireless image transmission ground terminal that can play multiple videos at the same time, support two-way voice communication, and distribute video data through wifi and 4G is very important. This is a co...

Problems solved by technology

[0004] The audio and video image transmission system solution for special environments described in the patent CN201410728994 integrates multiple networks to receive audio and video, but must have a complete set of equipment to complete the task when working in a team

And does not support multiple audio and video output methods

[0005] Judging from the current audio and video solutions for the ground station of image transmission equipment, there are many application solutions that have been applied, but from the perspective of audio and video distribution and collaboration, there are still no sufficient and effective solutions that are suitable for actual environment applications. example

[0006] The traditional unmanned image transmission ground station only considers single video output, and does not consider the situation of multi-channel video and voice fusion and video distribution
