Wireless FHD audio-video transmission device

Abstract

The invention discloses a wireless FHD audio-video transmission device. The system comprises an ARM core processor and a wireless transmission module, wherein the ARM core processor is used for collecting, compressing and encoding audio and video and configuring network functions, and the ARM core processor is connected with an audio module Audio Codec and a video collection module Video Receiver;an HDMI output interface and a USB interface are externally connected, and display and watching of video input signals are realized through the HDMI output interface or the USB interface; and the wireless transmission module has a built-in network Switch function, is externally connected with a network interface, is connected with the ARM core processor through a GMAC interface, and is used for realizing a network connection function of the ARM core processor and acquiring a video code stream needing to be wirelessly transmitted from the ARM core processor. The device can be used for conveniently realizing the broadcast directing and recording work of wireless HDMI, VGA and other audios and videos, and is high in usability and outstanding in stability.

Description

technical field [0001] The present invention relates to the technical field of audio and video transmission, and in particular, to a wireless FHD audio and video transmission device. Background technique [0002] At present, in the mobile recording and broadcasting system, miniaturization and wireless are the future trends. Since the environment of mobile recording and broadcasting is often not fixed, the less on-site wiring, the better, and the less reliance on the external environment, the better, such as figure 1 Shown is a schematic diagram of the solution of the mobile recording and broadcasting system in the prior art, the VGA video and audio signals output by the multimedia podium, and the HDMI output and audio signals of the external notebook. [0003] Depend on figure 1 It can be seen from: In the mobile recording and broadcasting environment in the classroom, the video recording of the camera is not counted. It only needs 4 wires to record the lecture notes and th...

Problems solved by technology

[0003] Depend on figure 1 It can be seen from the above: In the mobile recording and broadcasting environment in the classroom, not including the video recording of the camera, only 4 wires are needed to record the lecture notes of the classroom and the signal of the multimedia podium. If the classroom is not specially decorated and arranged for video connection, the on-site wiring The environment will be very complicated, which not only affects the recording effect, but also loses the portability advantage of mobile recording and broadcasting
