Description

Technical Field

[0001] The present invention relates to the technical field of video conference systems, and in particular to a dual hot backup video conference system. Background Art

[0002] Video conferencing system, also known as conference television system, refers to a system device that enables two or more individuals or groups in different places to communicate with each other through transmission lines and multimedia equipment, such as voice, image and file data, to achieve instant and interactive communication and realize remote conferencing. The use of video conferencing is a bit like a phone call. In addition to being able to see the person you are talking to and communicate verbally, you can also see their expressions and movements, so that people in different places can communicate as if they were in the same conference room.

[0003] In traditional video conferencing systems, the video conferencing terminal is connected to the mixer, the microphone is connected to the mixer, and finally the mixer is connected to the amplifier and the speaker. During the meeting, if any device in the system suddenly fails, the meeting may be interrupted, thus affecting the continuity of the meeting. As the core device of the video conferencing, the reliability of the signal transmission of the video conferencing terminal directly affects whether the video conferencing can proceed normally, so necessary backup measures are essential. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a dual hot backup video conferencing system, which can prevent the interruption of the video conference due to a sudden failure of the transmission and amplification hardware equipment during the video conference. The hot backup equipment intervenes without switching the equipment, thereby ensuring the continuity and stability of the video conference.

[0029] The hot backup audio mixer is connected to the audio input of the hot backup video conferencing terminal through the AUX3 interface, and the output of the hot backup video conferencing terminal is connected to the LINE4 interface of the hot backup audio mixer;

[0030] The main mixer is connected to the hot backup mixer interfaces LINE2 and LINE3 via interfaces AUX1 and AUX2; the hot backup mixer is connected to the main mixer interfaces LINE2 and LINE3 via interfaces AUX1 and AUX2.

[0031] A dual hot backup video conferencing system according to an embodiment of the present invention has at least the following beneficial effects: after the host of the main hand-in-hand conferencing system of this embodiment sends the audio to the hot backup conferencing console through AUX1 and AUX2 of the main mixing console, the LINE2 and LINE3 faders of the hot backup conferencing console are pushed, so that the microphone of the main hand-in-hand conferencing system can transmit and amplify the sound in the main hand-in-hand conferencing system of this embodiment, and can also transmit and amplify the sound in the hot backup hand-in-hand conferencing system at the same time. Similarly, the hot backup hand-in-hand conferencing system also transmits and amplifies the sound in two systems at the same time. After the video conferencing terminal sends the audio to the hot backup conferencing console through AUX1 and AUX2 of the main mixing console, the LINE2 and LINE3 faders of the hot backup conferencing console are pushed, so that the sound can be emitted by the main hand-in-hand conferencing system while the sound can be output in the hot backup hand-in-hand conferencing system. The MIC1 (main hand-in-hand conference system) of the main mixer and the AUX3 and AUX4 of LINE2 and LINE3 (hot backup mixer volume) send local volume to the video conference terminal, so that the signals of two groups of local microphones of the main hand-in-hand conference system and the hot backup hand-in-hand conference system are sent at the same time, playing the role of hot backup. Similarly, the hot backup video conference terminal can also send the volume to two mixers at the same time, and can also receive the volume of two hand-in-hand conference systems at the same time.

[0032] According to some embodiments of the present invention, the main mixing console is connected to a first equalizer, and the first equalizer is connected to a first feedback suppressor.

[0033] According to some embodiments of the present invention, the hot backup mixer is connected to the second equalizer, and the second equalizer is connected to the second feedback suppressor.

[0034] According to some embodiments of the present invention, a first power timer is also included, and interfaces 3-8 of the first power timer are respectively connected to the main hand-in-hand conference system host, the main mixing console, the first equalizer, the first feedback suppressor, the digital audio processor, the second post-stage power amplifier, and the first post-stage power amplifier.

[0035] According to some embodiments of the present invention, a second power timer is also included, and interfaces 3-8 of the second power timer are respectively connected to the hot backup hand-in-hand conference system host, the hot backup mixing console, the second equalizer, the second feedback suppressor, the digital audio processor, the fourth post-stage power amplifier, and the third post-stage power amplifier.

[0036] In this embodiment, by adding hot backup equipment in the traditional conference video system, even if a device suddenly stops working during the video conference, it will not affect the local sound reinforcement and remote transmission of the video conference.

[0037] For example, if the main hand-in-hand conference system microphone fails: the main hand-in-hand conference system microphone and the hot backup hand-in-hand conference system microphone are placed in front of the speaker at the same time. When the main microphone suddenly stops working due to signal or power problems, the signal of the hot backup microphone will be output to the main mixer through the AUX1 and AUX2 channels of the hot backup mixer. At the same time, the main mixer can continue to send the LINE2 and LINE3 channels input by the hot backup mixer to the video conference terminal through the AUX3 and AUX4 channels to ensure that the video conference transmission is not affected. The main output of the main mixer also locally amplifies the signal sent by the hot backup mixer.

[0038] For example, if the main mixer fails: the speaker is placed in front of both the main hand-in-hand conference system microphone and the hot backup hand-in-hand conference system microphone. When the main mixer suddenly loses power and is damaged, the hot backup mixer, hot backup hand-in-hand conference system, and hot backup video conference terminal become an independent system to work. The hot backup microphone is input to the hot backup mixer through MIC1, and the hot backup mixer performs local sound amplification through the main output, and sends the microphone signal to the hot backup terminal through AUX1 and AUX2, so as not to interrupt the meeting.

[0039] For example, if the main video conferencing terminal suddenly fails: when the network or equipment fails at the main video conferencing terminal, the main mixer signal is sent to the hot backup mixer through AUX1 and AUX2. The hot backup mixer can send the main mixer signal to the hot backup video conferencing terminal through AUX3 and AUX4, thereby ensuring that the video conference is not terminated.

[0040] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
