Description

Technical Field

[0001] The present invention relates to the field of audio and video fusion platforms, and in particular to an audio and video fusion platform based on H.265 architecture. Background Art

[0002] Existing conference systems are mainly divided into traditional audio and video systems and distributed systems. The traditional audio and video system is as shown in the attached manual. Figure 4 The following problems are shown: 1. The traditional audio and video system is a stack of multiple devices. The devices are connected offline and then controlled by a professional central control system. The large number of devices increases the variables of system stability. 2. The large number of devices means the large number of wires. The debugging and subsequent maintenance require professional personnel to be competent for the debugging of the system. The subsequent use also requires professional training before use.

[0003] Distributed system as attached Figure 5 As shown, the distributed system has the following problems: 1. Although it can be placed close to the signal source and the display screen, all network cables need to be connected to the cabinet switch, which makes it very inconvenient to organize the cabinet later and is not conducive to cable management; 2. The distributed system also needs to configure the server to uniformly forward commands to all devices in order to manage and use the system, which will increase the cost of the system.

[0004] In order to solve the problems of equipment stacking, cumbersome wiring, difficult maintenance, high cost, controllability and security of traditional audio and video systems and distributed systems in conference rooms, an audio and video fusion platform based on H.265 architecture is proposed. The signal source is directly connected through the finished jumper, which makes the wiring process more convenient. Audio, video and control are integrated into one. One device meets multiple functional requirements and can be installed in a standard cabinet, making the installation process more convenient. The interface is connected through the finished short jumper, and there is no need for manual wiring, which increases stability and facilitates the later arrangement of cabinets and after-sales maintenance. Compared with traditional audio and video platforms, it is more convenient to manage cables, and can be externally controlled by third-party devices to realize cameras, projectors, TVs, lights, curtains, screens and other equipment, making central control more convenient. Summary of the invention

[0005] The present invention provides an audio and video fusion platform based on the H.265 architecture, which solves the drawbacks of traditional audio and video systems and distributed systems, combines the characteristics of traditional audio, video and control, integrates the speech module, audio module, video module, control module and network module, controls the equipment through the network, realizes the audio and video signal switching and the third device control problem.

[0007] The method of use includes the following steps:

[0008] S1: After the audio interface collects the audio signal, the audio is exchanged through the embedded network through the ADI chip, the video and control are exchanged through the HiSilicon chip, and the audio is edited and processed into a Dante signal through an independent core algorithm. The Dante protocol signal can be directly given to the device supporting the Dante protocol through the network, and the sound reinforcement interface can be given to the power amplifier through the audio cable to achieve the sound reinforcement effect.

[0009] S2: After the video input and output interface collects the video signal, the video signal is encoded through the H.265 protocol through the HiSilicon chip to make it a network signal. Through the visual control software, the encoded video can be routed and decoded and output through H.265. The corresponding display device is connected through the video input and output interface to realize the functions of windowing, splicing, split screen, overlay, roaming, picture-in-picture, and plan management of the video signal;

[0011] S4: The main body of the audio and video fusion platform collects power through the power interface, converts the 220V voltage into the power supply of each module, and then powers the device. After the device is operating normally, it collects signals through the audio interface for encoding, and converts the audio and video signals into network signals. After arbitrary routing through the software, it is sent to the decoder, and then the network signal is converted into audio and video signals through the decoder. The corresponding terminal is connected through the output interface, and the control signal is directly forwarded through the network. After identification and output through the algorithm, the control of the third-party device is realized;

[0012] S5: The device realizes the transformation of audio and video signals from networking to digitalization through real-time encoding and decoding of audio and video signals. After real-time collection, analysis and processing of network data by software, it realizes visual control of audio and video, thus achieving a what-you-see-is-what-you-get effect and realizing fool-proof operation of the system.

[0013] Based on the above technical solution, the present invention can also be improved as follows.

[0014] Furthermore, the speaking interface and the sound reinforcement interface are 4-way analog Phoenix terminal interfaces.

[0015] Furthermore, the video input and output interface is a 4-way HDMI interface.

[0016] Furthermore, the audio and video fusion platform device body can route the audio signal directly to the video board internally to achieve embedding and de-embedding of the audio signal.

[0017] Furthermore, the sound reinforcement adopts a dual backup method, analog plus network, the analog uses a 4x250w amplifier module, and the digital uses PoE+Dante technology to achieve audio amplification.

[0018] Furthermore, the speaking interface adopts U communication technology to realize audio pickup of the microphone, and sends the sound to the audio processing module for sound processing. A single device supports 8 speaking microphones.

[0019] Furthermore, the audio and video fusion platform device body has an output image adjustment function, and supports adjustment of image brightness, hue, contrast, saturation and other parameters.
