[0028] The intelligent multimedia conferencing system proposed in the embodiments of this application will be described in detail below:

[0029] like Figure 1 As shown, Figure 1 This is an overall block diagram of an intelligent multimedia conferencing system according to an embodiment of this application. The intelligent multimedia conferencing system includes: a central control host 1, a wired conferencing unit 2, a wireless conferencing unit 3, an audio processing unit 4, a video processing unit 5, an audio playback terminal 6, a display terminal 7, and multiple camera devices 8. The central control host 1 is connected to the wired conferencing system, the wireless conferencing system, the audio processing unit 4, the video processing unit 5, and each of the camera devices 8. The wired conferencing unit 2 and the wireless conferencing unit 3 are both connected to the audio processing unit 4 and the video processing unit 5, respectively. The audio processing unit 4 is connected to the audio playback terminal 6, and the video processing unit 5 is connected to the display terminal 7.

[0030] The video processing unit 5 includes a video matrix converter 51, a video decoder 52, a video encoder 53, a switch 54, a splicing processor 55, and a recording and broadcasting device 58. The switch 54 is connected to the video decoder 52, the recording and broadcasting device 58, the video encoder 53, and each of the camera devices 8 via Cat6 Ethernet cables. The video matrix converter 51 is connected to the audio processing unit 4, the video decoder 52, the video encoder 53, and the splicing processor 55 via HDMI interfaces, and is also connected to the central control host 1 via a serial port. The splicing processor 55 is connected to the display terminal 7 via a Cat6 Ethernet cable, the recording and broadcasting device 58 is connected to the central control host 1 via a Cat6 Ethernet cable, and the video encoder 53 is connected to the central control host 1 via a Cat6 Ethernet cable.

[0031] The wired conferencing unit 2 and / or the wireless conferencing unit 3 control each of the camera devices 8 via the central control host 1. When the recording and playback device 58 is turned on and the camera devices 8 are turned on, the video input from the camera devices 8 is converted by the switch 54, the video encoder 53, the video matrix converter 51, the video decoder 52, and the splicing processor 55, and the converted video is input to the display terminal 7. The audio processing unit 4 processes the audio input from the wired conferencing unit 2 and / or the wireless conferencing unit 3, and plays the processed audio through the audio playback terminal 6.

[0032] Specifically, the central control unit 1 can connect to wired conferencing unit 2, wireless conferencing unit 3, audio processing unit 4, video processing unit 5, audio playback terminal 6, and multiple camera devices 8. Regarding video line processing, either wired conferencing unit 2 or wireless conferencing unit 3 can control the camera devices 8 to turn on and off via the central control unit 1. Then, the video input from the camera devices 8 is converted via the switch 54, the video encoder 53, the video matrix converter 51, the video decoder 52, and the splicing processor 55. The converted video has excellent quality and is input to the display terminal 7 via a Category 6 network cable (Category 6 network cable can be represented as CAT6, which has characteristics such as good transmission effect and fast transmission speed). This allows the display terminal 7 to play the converted video, meaning it can synchronously update the meeting video required by wired conferencing unit 2 or wireless conferencing unit 3 to the display terminal 7. Simultaneously, the meeting can be recorded via the recording device 58.

[0033] Regarding audio processing, the audio input from the wired conferencing unit 2 and / or the wireless conferencing unit 3 is processed by the audio processing unit 4, and the processed audio is played back through the audio playback terminal 6. This separates the video and audio processing lines. Video processing is performed through the central control unit 1, while audio processing can be performed directly through the audio processing unit 4 and the audio playback terminal 6 without going through the central control unit 1. This separation of video and audio lines avoids the problem of poor video and audio transmission quality caused by messy wiring in existing technologies.

[0034] Furthermore, the wired conferencing unit 2 includes a wired conferencing host 21, an eight-core conferencing cable 22, and multiple first audio receiving terminals 23; the wired conferencing host 21 is connected to the central control host 1 via a Category 6 network cable, and is connected to each of the first audio receiving terminals 23 via the eight-core conferencing cable 22; the wired conferencing host 21 is connected to the audio processing unit 4 via a dual-core microphone cable; wherein, the wired conferencing host 21 turns each of the camera devices 8 on / off through the central control host 1, and is used to input the audio input from each of the first audio receiving terminals 23 into the audio processing unit 4.

[0035] Specifically, such as Figure 2 As shown, Figure 2 This is a structural diagram of an intelligent multimedia system, in which the wired conferencing unit 2 includes a wired conferencing host 21, an eight-core conferencing cable 22, and multiple first audio receiving terminals 23. The first audio receiving terminal 23 can specifically be a wired microphone. In this embodiment, the number of first audio receiving terminals 23 can be 18. Each first audio receiving terminal 23 is connected to the wired conferencing host 21 via the eight-core conferencing cable 22. The first audio receiving terminal 23 can receive external sound sources (audio) and then transmit the audio through the wired conferencing host 21 to the audio processing unit 4 (i.e., Figure 2 The audio is played through the mixing console 41 and then through the audio playback terminal 6.

[0036] Furthermore, the wireless conferencing unit 3 includes multiple second audio receiving terminals 31, a wireless control terminal 32, and an antenna amplifier 33. The wireless control terminal 32 is connected to the antenna amplifier 33 via a feeder line and is connected to each of the second audio receiving terminals 31 and the central control host 1 via a serial port. The wireless control terminal 32 is also connected to the audio processing unit 4 via a dual-core microphone cable. The wireless control terminal 32 turns each of the camera devices 8 on / off via the central control host 1. The wireless control terminal 32 receives audio input from each of the second audio receiving terminals 31 and inputs the audio to the audio processing unit 4.

[0037] Specifically, continue to refer to Figure 2 As shown, the wireless conferencing unit 3 includes multiple second audio receiving terminals 31, a wireless control terminal 32, and an antenna amplifier 33. The second audio receiving terminal 31 can specifically be a wireless microphone. Through the second audio receiving terminal 31 and the antenna amplifier 33, it can receive externally emitted sound sources (audio) and transmit the sound source (audio) to the wireless control terminal 32. Then, the wireless control terminal 32 transmits the sound to the audio processing unit 4 (i.e.,...). Figure 2The audio source (audio) is input into the mixing console 41, and then the audio processing unit 4 controls the audio to adjust the volume, frequency, and mute / enable various volume channels, so that the audio played by the audio playback terminal 6 is the audio with the desired effect. Therefore, the combination of wired conferencing unit 2 and wireless conferencing unit 3 can adapt to various conferencing scenarios, and the audio processing unit 4 can process the audio according to the volume and audio requirements, so that the audio played by the audio playback terminal 6 has the best effect, improving the auditory effect during the meeting.

[0038] Furthermore, the video processing unit 5 also includes a wireless routing device 56 and a portable terminal 57. The wireless routing device 56 is connected to the switch 54 via a Category 6 network cable and is also communicatively connected to the portable terminal 57.

[0039] Specifically, the wireless routing device 56 can be a wireless router, and the portable terminal 57 can be a portable terminal device such as a mobile phone or tablet. The wireless router is connected to the switch 54 via a Category 6 network cable, so that the converted video can be sent to the portable terminal 57 via the wireless router (i.e., via WIFI). In this way, the portable terminal 57 can watch the video and audio of the meeting in real time, and the meeting can be conducted in multiple ways, such as remote and near distance, which improves the applicable scenarios of the meeting and provides great convenience for users of remote meetings. At the same time, due to the Category 6 network cable between the switch 54 and the wireless routing device 56, the transmitted meeting video has high real-time performance and low latency, and the audio interaction effect during the meeting is good.

[0040] Furthermore, the audio processing unit 4 includes a mixing console 41, multiple multimedia information boxes 42, and a digital audio processor 43; the mixing console 41 is connected to the digital audio processor 43, the wired conference host 21, the wireless control terminal 32, the recording and broadcasting device 58, and each of the multimedia information boxes 42 via dual-core microphone cables; the digital audio processor 43 is connected to the audio playback terminal 6, and each of the multimedia information boxes 42 is connected to the video matrix processor via dual-core microphone cables.

[0041] Specifically, such as Figure 3As shown, the mixing console 41 is equipped with multiple audio interfaces 411, volume adjustment channels 412, and other functional components. The audio interfaces 411 can receive audio input from the wired conferencing unit 2 and the wireless conferencing unit 3. The volume adjustment channels 412 can adjust the volume and frequency of the audio input corresponding to each first audio receiving terminal 23 in the wired conferencing unit 2, and can also adjust the volume and frequency of the audio input corresponding to each second audio receiving terminal in the wireless conferencing unit 3. A dual-core microphone cable is... Figure 2 The RVPE2*0.5 shown is shown.

[0042] The multimedia information box 42 can be used in an information management system to publish multimedia information such as meeting content. Through the multimedia information box 42, audio can be input into the video matrix converter 51, which converts the video and audio and sends them to the splicing processor 55. This allows the combined video and audio to be displayed and played on the display terminal 7. At the same time, it can be combined with wired and wireless microphones to play the audio of the meeting speakers on the audio playback terminal 6, making the meeting content richer. The meeting speakers can also comment on the played video through the wired conference unit 2 or the wireless conference unit 3, making the meeting process richer and more vivid, and improving the meeting effect.

[0043] The intelligent multimedia conferencing system also includes a first power supply 9 and a second power supply 10. Both the first power supply 9 and the second power supply 10 are connected to the central control host 1. The first power supply 9 is used to provide power to the audio processing unit 4, and the second power supply 10 is used to provide power to the display terminal 7.

[0044] Specifically, the first power supply 9 is used to control the power amplifier and provide power to components such as the mixing console 41 and the wireless microphone, while the second power supply 10 is used to provide power to the display terminal 7.

[0045] Furthermore, the intelligent multimedia conferencing system also includes a feedback suppressor 11, which is connected to the mixing console 41 via a dual-core microphone cable.

[0046] The feedback suppressor 11 is an automatic feedback point device that immediately detects and calculates the frequency and attenuation of acoustic feedback when it occurs, and executes a command to suppress the acoustic feedback according to the calculation results. During the suppression of acoustic feedback, the impact on other frequencies is greatly reduced. Therefore, the feedback suppressor 11 can reduce the influence of audio input from the wired conferencing unit 2 and / or the wireless conferencing unit 3.

[0047] In one embodiment of this application, the audio playback terminal 6 includes a plurality of array speakers 61, each of which is connected to the digital audio processor 43 via a dual-core microphone cable.

[0048] Specifically, in the embodiments of this application, the number of array speakers 61 is set to two, one of which is the main speaker and the other is the auxiliary speaker. After receiving the audio input from the mixing console 41, the digital audio processor 43 can convert the audio into digital form, so that each array speaker 61 can recognize the converted audio and play it.

[0049] In summary, the central control unit 1 can connect to wired conferencing unit 2, wireless conferencing unit 3, audio processing unit 4, video processing unit 5, audio playback terminal 6, and multiple camera devices 8. Regarding video line processing, either wired conferencing unit 2 or wireless conferencing unit 3 can control the camera devices 8 to turn on and off via the central control unit 1. Furthermore, the video input from the camera devices 8 is converted via the switch 54, the video encoder 53, the video matrix converter 51, the video decoder 52, and the splicing processor 55. The converted video has excellent quality and is then input to the display terminal 7, enabling the display terminal 7 to play the converted video. This means that the meeting video required by wired conferencing unit 2 or wireless conferencing unit 3 can be synchronously updated to the display terminal 7. Simultaneously, the meeting can be recorded via the recording device 58.

[0050] Regarding audio processing, the audio input from the wired conferencing unit 2 and / or the wireless conferencing unit 3 is processed by the audio processing unit 4, and the processed audio is played back through the audio playback terminal 6. This separates the video and audio processing lines. Video processing is performed through the central control unit 1, while audio processing can be performed directly through the audio processing unit 4 and the audio playback terminal 6 without going through the central control unit 1. This separation of video and audio lines avoids the problem of poor video and audio transmission quality caused by messy wiring in existing technologies.

[0051] Furthermore, the above figures are merely illustrative of the processes included in the method according to exemplary embodiments of this application, and are not intended to be limiting. It is readily understood that the processes shown in the above figures do not indicate or limit the temporal order of these processes. Additionally, it is readily understood that these processes may be executed synchronously or asynchronously in multiple modules.

[0052] It should be understood that this application is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
