Description
Technical Field
The disclosure relates to the technical field of audio and video signal processing, in particular to a multifunctional audio and video processing device.
Background
With the development of AI (artificial intelligence) technology in recent years, speech recognition technology is increasingly applied to occasions requiring on-site character recording, such as digital courtroom, digital conference room, intelligent classroom, and the like. The voices of a plurality of speakers on the spot are collected and automatically recognized into characters, and then the characters are output to character recording software such as court bookmaker software through a software interface, so that the workload of manually inputting the characters is greatly reduced. Because the existing multifunctional audio/video processing equipment is mainly used for recording and storing live audio/video, if a voice recognition function needs to be realized, taking a digital court as an example, in the related art, the solution shown in fig. 1 is generally adopted: a court is internally provided with at least 8 analog microphones, a plurality of cameras are used for video acquisition, a multifunctional audio and video processing device (supporting audio and video acquisition, processing, coding and storage), an 8-channel sound card, a gigabit network switch with 4 ports at the lowest, and local audio and video output devices such as a power amplifier, a sound box and a display. The sound card equipment has the main functions of connecting analog microphones, independently collecting analog audio signals of each microphone, producing digital audio streams, transmitting the digital audio streams to a voice recognition server through a network, returning recognized text information to the sound card in a character string mode, and outputting the recognized text information to writer writing software on a writer computer through a USB (universal serial bus) line or the network by the sound card. In order to transmit the sound of the field microphone to the sound card and to the multifunctional audio/video processing device, a multi-channel audio distributor and an audio matrix are added or the multifunctional audio/video processing device or the sound card is required to have an audio loop-out function, and since the general multifunctional audio/video processing device or the sound card does not have the multi-channel audio loop-out function, the multi-channel audio distributor and the audio matrix are mostly adopted for realization.
For the audio and video processing device in the related art, there are mainly some problems as follows: (1) the integration level of the equipment is poor, and in order to meet the functional requirements, an audio matrix, a sound card, a multifunctional audio and video processing device, audio connecting lines among the devices and the like need to be configured, so that the system deployment is complex, the workload of field device deployment, environment arrangement and the like is large, and the working efficiency is reduced; (2) there are more points of failure. Because a plurality of devices are used and dozens of connecting lines are simultaneously arranged, dozens of fault points exist in single project implementation, the project implementation requirement is high, the possibility of later-stage fault is high, and the later-stage project maintenance cost is increased; (3) the implementation cost is high. External audio switching equipment such as an audio matrix and the like need to be independently equipped for meeting the functional requirements, and meanwhile, the cost of the independent sound card and the multifunctional audio and video processing equipment is higher than that of equipment with higher integration degree. The large implementation workload also causes long implementation period and labor cost improvement.
Since the speech recognition function belongs to a technology which appears relatively late, the multifunctional audio and video processing equipment used in early digital courts, digital conference rooms, intelligent classrooms and the like has no way to be integrated when being developed. With the gradual maturity of the current voice recognition function, the requirement of assisting various word records in the field by voice recognition gradually becomes a standard requirement, and the requirement of integrating the voice recognition with the traditional multifunctional audio and video processing equipment is urgent.
