Double-link data switching processing method for digital simultaneous transmission system

Abstract

The invention provides a double-link data switching processing method for a digital simultaneous transmission system, and relates to the technical field of audio conferences. According to the method and the device, the framing data sequence and the framing mark sequence are obtained by unpacking the double-channel simultaneous transmission signal, and each channel of the frame is injected into the buffer in real time, so that the next to-be-played frame can be searched during switching, and the channel switching can be completed under the condition of not influencing the existing communication by switching the next frame; moreover, delay and loss are avoided, and the buffer is added, so that digital simultaneous transmission is smoother; in addition, automatic switching is carried out according to the data quality value, the data quality value can be measured through the signal-to-noise ratio mean value / packet loss rate of the current channel, the data quality value is calculated in real time through the processor and compared with the data quality threshold value in real time, and channel switching is carried out, so that better communication quality is obtained, and the whole switching process is non-inductive.

Description

technical field [0001] The invention relates to the technical field of audio conferencing, in particular to a dual-link data switching processing method for a digital simultaneous interpretation system. Background technique [0002] With the development of science and technology, our audio conferencing technology is also constantly updated. Digital simultaneous interpretation system, as an emerging system in the field of audio conferencing technology, continues to play a key role in various important meetings. [0003] The existing digital simultaneous interpretation system can receive simultaneous interpretation signals from different interpretation channels and distribute them to people with listening needs in different languages. However, at present, the simultaneous interpretation receiving unit often only provides a single way of signal reception. When a single signal is interfered, for example, the infrared signal has the problem of shading and other light wave interfe...

Problems solved by technology

[0005] However, this application cannot solve the problem of short-term interruption of the call when the dual-link data of the dual-channel simultaneous interpretation system is switched, and cannot guarantee the continuity of the simultaneous interpretation data. In addition, the application has not considered automatic / manual when the quality of the single signal is not good. Function to switch channels
