Problems solved by technology

[0005] However, the application is a single-channel communication unit, and its communication quality is unstable, so it cannot adapt to various scenarios. Guarantee the continuity of simultaneous transmission data. In addition, this application has not considered the function of automatic / manual channel switching when the single signal quality is not good

Abstract

The invention provides a real-time synchronous simultaneous transmission receiving unit based on optical path wireless and electromagnetic wave wireless, and relates to the field of synchronous simultaneous transmission hardware. According to the invention, the dual-channel simultaneous transmission signal is framed through the data framing module, the framing marking sequence is obtained through the framing marking module, and each channel of frame is injected into the buffer in real time, so that the next to-be-played frame can be searched during switching, and the switching efficiency of the next frame is improved by switching the next frame. Under the condition that existing communication is not affected, channel switching can be completed, delay and loss are avoided, and digital simultaneous transmission is smoother; through arranging the optical link indicating lamp and the electromagnetic wave link indicating lamp, the communication states of the optical link and the electromagnetic wave link can be indicated; the infrared signal and the WIFI signal are used as double-channel carriers, so that the device can adapt to various scenes such as remote communication, short-range communication, limited environment communication, open environment communication and the like, the applicable scenes of the device are greatly enhanced, and the communication quality is also greatly improved.

Description

technical field [0001] The invention relates to the field of synchronous simultaneous interpretation hardware, in particular to a real-time synchronous simultaneous interpretation receiving unit based on optical path wireless and electromagnetic wave wireless. Background technique [0002] Multilingual explanations are involved in organizing meetings in large international conference halls and multimedia exhibition halls for multimedia playback. The current method of multilingual explanations is simultaneous interpretation. In museums, memorial halls and other places, there are more and more tourists from different countries. , convenient operation, the use of simple multilingual explanations, and ways for tourists in different languages ​​to listen are also urgently needed. [0003] Based on the above reasons, people have created a simultaneous interpretation receiving unit, which can receive simultaneous interpretation signals from different translation channels and distri...
