Description

Video conference processing method, system, electronic device and storage medium

Technical Field

The present invention relates to the technical field of video conferencing, and in particular to a method for processing a video conferencing, a system for processing a video conferencing, an electronic device, and a computer-readable storage medium.

Background Art

In modern video conferencing systems, the security and confidentiality of data transmission are crucial factors. Therefore, more and more video conferencing systems have begun to adopt encryption technology to ensure that the content of the meeting will not be eavesdropped or tampered with during transmission. However, in actual applications, video conferencing systems often use a mixture of encrypted terminals and non-encrypted terminals. Among them, the encrypted terminal can encrypt the audio and video streams through an encryption algorithm to prevent unauthorized users from accessing the conference content. The non-encrypted terminal cannot directly decode the audio and video streams sent by the encrypted terminal due to the lack of decryption function. Therefore, in a conference environment where encrypted terminals and non-encrypted terminals are mixed, users of non-encrypted terminals cannot watch or hear the audio and video content from the encrypted terminals, which limits their ability to participate in the meeting.

To solve this problem, a current solution is to use an encrypted terminal (hereinafter referred to as "terminal A") to decode the encrypted audio and video stream, and then use the decoded audio and video signal as the input source of another non-encrypted terminal (hereinafter referred to as "terminal B"). In this way, terminal B can participate in the conference and pass the decoded audio and video stream to other non-encrypted terminals. However, this method has the following significant problems:

1. Delay problem: Since the audio and video streams need to be decoded and forwarded through terminal A, the transmission will introduce a large delay. This delay may have a negative impact on the real-time and interactivity of the meeting, especially in scenarios that require immediate response, which may lead to a significant decline in the meeting experience.

2. Complex operation: In order to achieve the above functions, two conferences usually need to be started at the same time - one for terminal A to decode the encrypted audio and video stream, and the other for terminal B to forward the decoded audio and video stream as the input source. This not only increases the complexity of the operation, but also requires close cooperation and coordination between multiple terminals, which brings additional burdens to conference organizers and participants.

3. Difficult management: Since the conference in which terminal B participates is independent of the conference in which terminal A is participating, the coordination between the two conferences becomes more difficult. For example, operators may need to frequently switch between two different conference interfaces to ensure the normal forwarding and reception of audio and video content, which brings a lot of inconvenience to the operation.

In summary, existing solutions have obvious deficiencies in conference scenarios where encrypted terminals and non-encrypted terminals are mixed.

DETAILED DESCRIPTION

In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

The video conference processing solution proposed in the embodiment of the present invention optimizes the conference environment that uses a mixture of encrypted terminals and non-encrypted terminals by configuring encrypted terminals and encrypted virtual terminals on the server. Specifically, after the server obtains the audio and video streams of the speaker's terminal, it uses the encrypted terminal to transmit the audio and video streams to the encrypted participant's terminal in the video conference. At the same time, for the non-encrypted participant's terminal in the video conference, the audio and video streams are transmitted to the non-encrypted participant's terminal through the encrypted virtual terminal. This solution simplifies the operating process, reduces the transmission delay of audio and video streams, unifies the management of encrypted and non-encrypted terminals, improves the compatibility of the system and the overall experience of the conference, and effectively solves the problems of large delays, complex operations and difficult management in traditional solutions.

1, a flowchart of a method for processing a video conference according to an embodiment of the present invention is shown. The method for processing a video conference can be applied to a server, and the method for processing a video conference can specifically include the following steps:

Step 101: configure an encryption terminal and an encryption virtual terminal for a video conference.

In an embodiment of the present invention, an encryption terminal refers to a device or software module that can encrypt audio and video streams. By using an encryption algorithm, the encryption terminal can convert audio and video data into ciphertext that cannot be directly interpreted, and only devices with corresponding decryption permissions can decode and play these audio and video contents. This type of encryption terminal is usually used to protect sensitive information and prevent unauthorized access. When configuring an encryption terminal, the server needs to consider multiple factors, including the type of encryption algorithm used, the management method of encryption keys, and the authentication mechanism between the terminal and the server. For example, when configuring an encryption terminal based on the Advanced Encryption Standard (AES) encryption algorithm, the server needs to ensure the secure storage and distribution of encryption keys, and assign a unique key to each encryption terminal to enhance security.

The encrypted virtual terminal is a software module used to simulate the functions of an encrypted terminal in a non-encrypted environment. It can receive encrypted audio and video streams and convert them into ordinary audio and video streams that can be received and played by non-encrypted terminals through the decryption process. The configuration of the encrypted virtual terminal needs to consider its integration with the server, the choice of decryption algorithm, and the forwarding mechanism of the data stream. For example, if the devices of non-encrypted participants do not support complex encryption protocols, the server can configure the encrypted virtual terminal to perform decryption operations on behalf of these devices, and then transmit the decrypted data stream to these devices to ensure that they can receive and play the conference content normally.

By configuring encrypted terminals and encrypted virtual terminals, the server can effectively manage the transmission of audio and video streams of encrypted and non-encrypted participants, and provide personalized services for participants with different security requirements. This not only enhances the security and flexibility of the system, but also lays the foundation for handling different types of terminals. In practical applications, a typical example is that a company's video conferencing system needs to handle the meeting needs of internal employees and external partners. The devices used by internal employees are encrypted terminals that can directly receive and decode encrypted audio and video streams, while the non-encrypted terminals used by external partners receive the decrypted data streams through encrypted virtual terminals to ensure the smooth progress of the meeting.

Step 102: Acquire the audio and video streams of the terminal of the speaker in the video conference.

In an embodiment of the present invention, the speaker terminal refers to the device used by the participant who is currently speaking or presenting. Obtaining audio and video streams generally involves two main processes: audio and video capture and data transmission. Audio and video capture refers to the real-time collection of image and sound signals at the conference site through hardware devices such as the camera and microphone of the speaker terminal. These signals are usually captured in an uncompressed or lightly compressed format to ensure the high quality of the audio and video content. For example, when using conference equipment with a high-definition camera and a professional microphone, the captured audio and video signals can reach a resolution of 1080p or even 4K, and the audio can also reach a sampling rate of more than 48kHz, which provides a clear and realistic communication experience for the meeting.

Data transmission refers to the process of transmitting captured audio and video signals to the server through the network. In this process, the speaker terminal needs to encode the audio and video signals (Encoding), compressing the original audio and video data into a format suitable for network transmission to reduce bandwidth usage and transmission delay. Common encoding formats include the H.264 video encoding standard and the Advanced Audio Coding (AAC) audio encoding standard, which can effectively reduce the amount of data while ensuring the quality of audio and video. During the transmission process, the speaker terminal also needs to use network protocols such as the Transmission Control Protocol (TCP) or the Real-time Transport Protocol (RTP) to ensure that the data is not lost or outdated during the transmission process, and can be correctly received and processed by the server.

In practical applications, such as a distance education system, the teacher's computer or mobile device is the speaking terminal. Through a high-definition camera and microphone, the teacher captures his or her own explanations and blackboard writings in real time as audio and video streams, which are then transmitted to the education platform server through the network. The server then forwards these audio and video streams to all online students to ensure that they can receive the teacher's lectures synchronously.

Step 103, for the encrypted participant terminal in the video conference, use the encrypted terminal to transmit the audio and video stream to the encrypted participant terminal.

In an embodiment of the present invention, the encryption terminal encrypts the acquired audio and video streams. Encryption processing refers to converting the audio and video streams into ciphertext through an encryption algorithm, so that unauthorized users cannot understand or access these data. Common encryption algorithms include symmetric encryption algorithms such as the Advanced Encryption Standard (AES) and asymmetric encryption algorithms. For video conferencing scenarios with high real-time requirements, symmetric encryption algorithms such as AES are usually selected because they have fast encryption and decryption speeds, which can reduce transmission delays while ensuring security.

After the encryption process is completed, the audio and video streams are transmitted from the encryption terminal to the encryption participant terminal in an encrypted format. During the transmission process, secure transmission protocols such as Transport Layer Security (TLS) or Secure Real-time Transport Protocol (SRTP) are used to ensure that the encrypted data is not eavesdropped or tampered with when transmitted on the network. These protocols further enhance the security of audio and video stream transmission through encrypted session keys and authentication mechanisms.

After receiving the encrypted audio and video stream, the encrypted participant terminal will use its locally stored decryption key to decrypt the data and restore it to playable audio and video content. For example, in a high-level meeting, the devices used by each participant are encrypted participant terminals. The server encrypts the speaker's audio and video stream through the encrypted terminal and transmits it to each encrypted participant terminal to ensure that the conference content will not be eavesdropped or tampered with by a third party during the transmission process. Each encrypted participant terminal will decrypt the received audio and video stream according to the pre-configured key, so that it can clearly and accurately receive and participate in the conference content.

Step 104, for the non-encrypted participant terminal in the video conference, use the encrypted virtual terminal to transmit the audio and video stream to the non-encrypted participant terminal.

In an embodiment of the present invention, since the non-encrypted participant terminal cannot directly decrypt the encrypted audio and video stream, the encrypted virtual terminal is used to decrypt the audio and video stream from the encrypted format to the ordinary format and then transmit it to the non-encrypted participant terminal. The encrypted virtual terminal will receive the encrypted audio and video stream from the encryption terminal. These audio and video streams are encrypted ciphertexts and cannot be used directly by the non-encrypted participant terminal. The task of the encrypted virtual terminal is to restore these ciphertexts to the original audio and video data through a decryption algorithm. This process usually involves a symmetric decryption algorithm, such as the decryption process in AES. The encrypted virtual terminal will use the decryption key shared with the encryption terminal to decrypt the audio and video stream frame by frame to ensure that the decrypted audio and video data is consistent with the original data.

After decryption is complete, the encrypted virtual terminal will encode and encapsulate the audio and video streams to conform to the format that the non-encrypted terminal can receive. For example, the formats supported by common non-encrypted participant terminals include H.264 video encoding and AAC audio encoding. This step ensures that the decrypted audio and video streams can be correctly recognized and played by the non-encrypted participant terminals. Subsequently, the encrypted virtual terminal transmits the decrypted audio and video streams to the non-encrypted participant terminals through standard transmission protocols such as RTP.

In actual applications, suppose that in a video conferencing system, some employees use encrypted participant terminals, while some external partners use non-encrypted participant terminals. The server encrypts the audio and video streams of the conference speaker through the encrypted terminal and transmits them to the encrypted virtual terminal. The encrypted virtual terminal then decrypts these audio and video streams and forwards them to the non-encrypted participant terminals of the external partners to ensure that they can receive and participate in the conference normally.

It should be noted that step 104 can be performed after step 102 or step 103.

The video conference processing scheme provided by the embodiment of the present invention is applied to a server. The server configures an encryption terminal and an encryption virtual terminal for the video conference. The audio and video stream of the speaker terminal in the video conference is obtained. Furthermore, for the encrypted participant terminal in the video conference, the audio and video stream is transmitted to the encrypted participant terminal of the video conference using the encryption terminal, and for the non-encrypted participant terminal in the video conference, the audio and video stream is transmitted to the non-encrypted participant terminal of the video conference using the encryption virtual terminal.

The embodiment of the present invention processes audio and video streams through the encryption terminal and encryption virtual terminal configured by the server, avoiding the complex process of A terminal decoding and B terminal forwarding in the traditional solution, and reducing the transmission delay of the audio and video stream. This helps to improve the real-time nature of the meeting and improve the interactive experience of the participants, especially in the meeting scene that requires a quick response, which is more effective. The server directly manages the audio and video stream transmission of the encryption terminal and the encryption virtual terminal, avoiding the complex coordination between the two meetings and multiple terminals that need to be manually opened in the traditional solution. This not only simplifies the operation process, but also reduces the skill requirements for operators and improves the efficiency of conference organization and management. Through the centralized management of encryption terminals and encryption virtual terminals by the server, the coordination problem between two independent meetings in the traditional solution is eliminated. The operator only needs to manage all participating terminals in a unified conference interface, without frequently switching the conference interface, thereby greatly reducing the complexity of management, improving the convenience of operation and the controllability of the meeting. By introducing the encryption virtual terminal, the non-encrypted participants can smoothly receive the conference audio and video streams, thereby improving the compatibility of the encryption terminal and the non-encrypted terminal in the mixed use scenario. This means that there is no need to upgrade or replace the hardware of existing non-encrypted terminals, which reduces costs and enhances the flexibility of the system.

In summary, the embodiments of the present invention effectively solve the problems of delay, operation complexity and management difficulty in the background technology, and bring a more efficient and simpler conference experience.

In an exemplary embodiment of the present invention, an implementation method for configuring an encryption terminal and an encryption virtual terminal for a video conference is to set the encryption terminal as the host role of the video conference, and establish an exclusive intercommunication tunnel between the encryption terminal and the encryption virtual terminal by sending a broadcast. In actual application, the encryption terminal is configured as the host role of the video conference, which means that the encryption terminal will assume the core management and control functions of the video conference. In a video conference, the host role is usually responsible for starting and ending the conference, managing the permissions of the participants, controlling the order of speaking, and allocating and managing audio and video resources. By assigning this role to the encryption terminal, it can be ensured that all sensitive management operations are performed in an encrypted environment, thereby preventing unauthorized users from accessing the conference management function. This also means that the encryption terminal can use its built-in encryption algorithm (such as AES) to encrypt all management commands and conference data, further improving the security of the meeting.

On this basis, an exclusive intercommunication tunnel is established between the encryption terminal and the encryption virtual terminal through broadcasting to ensure the secure transmission of encrypted data between multiple terminals. Broadcasting here means that the encryption terminal sends data to a specific group of recipients (i.e., encryption virtual terminals) without transmitting to other non-target terminals. An exclusive intercommunication tunnel refers to a secure channel established between the encryption terminal and the encryption virtual terminal for transmitting encrypted audio and video data and management commands. The establishment and maintenance of this tunnel depends on encrypted communication protocols (such as TLS) and encryption algorithms to ensure that data is not eavesdropped or tampered with during transmission.

The advantage of this implementation is that it enables encrypted data and management commands in the video conferencing system to be quickly and reliably transmitted to all encrypted virtual terminals in a broadcast manner, thereby achieving compatible support for non-encrypted participant terminals. For example, when a video conference needs to connect multiple encrypted participants and non-encrypted participants at the same time, the encrypted terminal can ensure that the encrypted data is only transmitted to the encrypted virtual terminal that needs to be decrypted through the dedicated tunnel established by the broadcast, while the non-encrypted participant terminal only receives the decrypted data stream, thereby ensuring the overall security and data consistency of the system.

Since the encrypted terminal is given the role of host, the system administrator no longer needs to manually distribute and manage encryption keys or configure secure channels between multiple terminals, which reduces management complexity and reduces the risk of operational errors. The encrypted terminal automatically establishes an intercommunication tunnel with the encrypted virtual terminal through broadcasting, ensuring that all participating terminals that need to decrypt data can seamlessly receive the conference content. This not only improves the operability of the system, but also enhances the fluency and real-time nature of video conferencing, which has significant advantages, especially in large-scale meetings that need to connect a large number of participants.

In an exemplary embodiment of the present invention, an implementation method of transmitting audio and video streams to an encrypted participant terminal using an encryption terminal is that if the speaker terminal belongs to an encrypted participant terminal, the audio and video streams are transmitted to the encryption terminal, and the encryption terminal is used to transfer the audio and video streams to other encrypted participant terminals of the video conference. An encrypted participant terminal refers to a terminal device with encryption function, which can encrypt and decrypt audio and video streams through encryption algorithms to ensure that the data is not eavesdropped or tampered with during transmission. When the speaker terminal itself is also an encrypted participant terminal, the audio and video streams it generates are naturally encrypted. This encryption is usually based on a symmetric encryption algorithm, which can improve the efficiency of encryption and decryption while ensuring security.

In actual application, the audio and video streams generated by the encrypted participant terminal are transmitted to the encryption terminal. As the core management device of the video conference, the encryption terminal is responsible for the centralized processing and forwarding of audio and video streams. Since the audio and video streams of the speaker terminal have been encrypted, the security of the data can be fully guaranteed during the transmission to the encryption terminal. The encryption terminal only needs to perform necessary management and scheduling without the need to perform secondary encryption on the audio and video streams. This design greatly simplifies the processing flow of the system and also reduces the delay of data during transmission. Next, the encryption terminal is used to forward the audio and video streams to other encrypted participant terminals of the video conference. In this process, the encryption terminal plays the role of "data relay". It receives the encrypted audio and video streams from the speaker terminal and distributes these data to other encrypted participant terminals according to the actual needs of the conference. Since these terminals have decryption capabilities, they can directly decode and play the audio and video streams received from the encryption terminal, thereby ensuring the synchronization and consistency of the conference content between different encryption terminals.

In the embodiment of the present invention, the audio and video streams are always encrypted throughout the entire transmission chain through the intermediary role of the encryption terminal, which avoids any possible risk of eavesdropping or data leakage. The data transmitted between multiple encrypted conference participant terminals is also protected, ensuring the confidentiality of the conference content. Since the encryption terminal centrally processes and transcodes the audio and video streams, direct communication between multiple terminals is reduced, and the network bandwidth occupancy is reduced. In addition, the efficient scheduling capability of the encryption terminal enables audio and video data to be quickly and stably transmitted to each encrypted conference participant terminal, reducing the delay problem caused by multi-terminal collaboration, thereby improving the fluency and real-time nature of the meeting. System administrators no longer need to manually configure encryption keys or set up dedicated channels between different terminals. All encryption and decryption processes are centrally managed by the encryption terminal, and the terminal device only needs to communicate with the encryption terminal according to a predetermined protocol. This centralized management not only reduces the complexity of operation, but also reduces the risk of configuration errors, ensuring the stable operation of the system.

In an exemplary embodiment of the present invention, an implementation method of transmitting audio and video streams to non-encrypted participant terminals using an encrypted virtual terminal is that if the speaker terminal belongs to an encrypted participant terminal, the audio and video streams are transmitted to the encrypted terminal, and the encrypted terminal is used to transfer the audio and video streams to the encrypted virtual terminal through a dedicated intercommunication tunnel; the encrypted virtual terminal is used to decrypt the audio and video streams, and the decrypted audio and video streams are transmitted to the non-encrypted participant terminals of the video conference. In actual application, when the speaker terminal is an encrypted participant terminal, the generated audio and video streams are encrypted. These encrypted data are transmitted to the encryption terminal through a secure channel. The encryption terminal plays a core management and scheduling role in the video conferencing system. Its main task is to receive audio and video streams from the encrypted participant terminals and use a dedicated intercommunication tunnel to securely transmit these data to the encryption virtual terminal. Next, the encryption virtual terminal decrypts the received audio and video streams. The decryption process usually uses the same decryption algorithm as the encryption terminal, such as AES, to ensure that the data can be correctly restored to the original audio and video content. The decrypted audio and video streams are then transmitted to the non-encrypted participant terminals. These terminals do not have decryption capabilities, so the decryption operation of the encrypted virtual terminal is a key step to ensure that the non-encrypted participant terminals can receive the conference content normally. In this way, non-encrypted participant terminal users can participate in the conference synchronously with encrypted participant terminal users without being restricted by encryption technology.

The embodiment of the present invention uses the encryption terminal and the encryption virtual terminal as intermediaries, and all audio and video streams are encrypted during the transmission process and are only decrypted in the encryption virtual terminal, thereby preventing the leakage of sensitive data. This is particularly important for meetings that require high security, such as corporate confidential meetings or government agency meetings. Since the encryption virtual terminal is responsible for decrypting and transcribing the audio and video streams, the non-encrypted participant terminal can participate in the video conference without encryption and decryption functions. This design enables different types of terminal devices to work together in the same conference environment, improves the flexibility of the system, and adapts to a variety of application scenarios. Through the exclusive intercommunication tunnel, the communication between the encryption terminal and the encryption virtual terminal is optimized, reducing the delay in data transmission. In addition, the decrypted data is directly transmitted from the encryption virtual terminal to the non-encrypted participant terminal, which simplifies the path of the data flow and avoids unnecessary intermediate processing links. This method ensures the real-time transmission and synchronization of the conference content, thereby improving the user's conference experience.

In an exemplary embodiment of the present invention, an implementation method of transmitting an audio and video stream to an encrypted participant terminal using an encryption terminal is that if the speaker terminal belongs to a non-encrypted participant terminal, the audio and video stream is transmitted to the encryption terminal, and the audio and video stream is encrypted by the encryption terminal; the encrypted audio and video stream is forwarded to the encrypted participant terminal of the video conference by the encryption terminal. In actual application, the non-encrypted participant terminal refers to a terminal device without a built-in encryption function. The audio and video streams generated by these terminals in the video conference are unencrypted, which means that they are vulnerable to the risk of eavesdropping or tampering. Therefore, when the non-encrypted participant terminal is used as the speaker, in order to ensure the security of the conference data, the audio and video stream needs to be transmitted to an encryption terminal with encryption capability. After receiving the audio and video stream from the non-encrypted participant terminal, the encryption terminal will immediately perform encryption processing. Encryption processing usually uses a symmetric encryption algorithm, such as AES, which can ensure both the security of the data and the efficiency of the encryption processing. During the encryption process, the original audio and video data is converted into encrypted data, and only the encrypted participant terminal with the corresponding decryption capability can decode and restore it. After encryption is completed, the encryption terminal forwards the encrypted audio and video stream to other encrypted participant terminals in the conference. These encrypted participant terminals have decryption capabilities and can perform decryption operations through pre-shared keys or public key encryption systems to restore the original audio and video content. This method ensures that all encrypted participant terminals can synchronously receive and correctly decode the audio and video streams while protecting the confidentiality of the data.

The embodiment of the present invention prevents unauthorized users from eavesdropping or tampering with the content of the meeting by encrypting the audio and video streams generated by the non-encrypted participant terminal at the encryption terminal. This method is particularly suitable for video conferencing scenarios that require high security, such as corporate confidential meetings or remote meetings of government departments. Since the encryption terminal can encrypt the audio and video streams from the non-encrypted participant terminal, it ensures that different types of terminal devices in the meeting can work together. In a conference environment where encrypted and non-encrypted terminals are mixed, this design provides the system with greater flexibility, enabling it to adapt to different application requirements. By centralizing encryption processing on the encryption terminal, direct communication and encryption configuration processes between multiple terminals are reduced, the data stream transmission path is optimized, and the network bandwidth occupancy is reduced. This centralized encryption processing method not only improves the efficiency of data transmission, but also reduces the delay problem that may be caused by the collaborative processing of multiple terminals, thereby improving the real-time and interactivity of the meeting.

In an exemplary embodiment of the present invention, an implementation method of using an encrypted virtual terminal to transmit an audio and video stream to a non-encrypted participant terminal is that if the speaker terminal belongs to a non-encrypted participant terminal, the audio and video stream is transmitted to the encrypted virtual terminal, and the encrypted virtual terminal is used to forward the audio and video stream to other non-encrypted participant terminals of the video conference. In actual application, when the speaker terminal is a non-encrypted participant terminal, the audio and video stream generated by it is transmitted to the encrypted virtual terminal. The encrypted virtual terminal is a virtualized encryption device that simulates the function of the encryption terminal and can process the audio and video stream securely without changing the non-encrypted terminal hardware. In this process, after receiving the audio and video stream from the non-encrypted participant terminal, the encrypted virtual terminal will perform necessary security checks and processing on the data to ensure that it can continue to be transmitted on a secure basis. Next, the encrypted virtual terminal will forward the processed audio and video stream to other non-encrypted participant terminals in the video conference. For example, in a remote conference of an enterprise, the device used by the speaker of the M department is a non-encrypted participant terminal, and the participants of the N department also use non-encrypted participant terminals. At this point, the audio and video streams of the spokesperson of Department M will be transmitted to the encrypted virtual terminal, which will process them and then transmit them to all participants of Department N. Since the encrypted virtual terminal can serve as a transit station and security protection layer for audio and video streams, this ensures that the transmission of audio and video streams can still be well managed and controlled even in a non-encrypted environment.

The embodiments of the present invention can ensure that the non-encrypted participant terminals can still participate in video conferences with a higher security level without upgrading or replacing existing hardware equipment by using encrypted virtual terminals. The use of encrypted virtual terminals does not require physical changes to the non-encrypted participant terminals, which provides great convenience for large-scale deployments or when resources are limited. In a traditional hybrid environment, operators may need to manually adjust the configurations of multiple terminals to ensure the smooth progress of the meeting. Through the centralized management of encrypted virtual terminals, the reception and transmission of audio and video streams can be automated, reducing the complexity of conference management and the risk of errors caused by human operations. For example, in a global meeting of a multinational company, since participants may be distributed in different countries and regions and use different types of equipment, the unified management of encrypted virtual terminals can effectively simplify the deployment and management of meetings on a global scale.

In an exemplary embodiment of the present invention, an implementation method of transmitting the decrypted audio and video stream to the non-encrypted participant terminal of the video conference is to perform resolution conversion processing on the decrypted video stream and perform bit rate conversion processing on the decrypted audio stream; the video stream after resolution conversion and the audio stream after bit rate conversion are transmitted to the non-encrypted participant terminal of the video conference. In a video conferencing system, in order to ensure seamless transmission of audio and video content between different terminals, especially in an environment where encrypted and non-encrypted terminals are mixed, the audio and video streams need to be properly processed. In particular, when the audio and video stream needs to be transmitted from an encrypted terminal to a non-encrypted terminal, the decrypted audio and video stream may need to be further optimized to ensure that different types of terminals can normally receive and play these streaming media contents. In actual application, after the audio and video stream is decrypted by the encrypted virtual terminal, the video stream and the audio stream need to be further processed. The decrypted video stream may have a higher resolution, which may not be perfectly presented on some non-encrypted participant terminals, or may cause problems such as freezes and delays during playback. Therefore, it is a necessary step to perform resolution conversion processing on the video stream. Resolution conversion is a technology that adjusts the pixel density of a video to adapt it to the resolution of the target display device. For example, a 1080p (1920×1080 pixels) high-resolution video stream is converted to 720p (1280×720 pixels) or 480p (854×480 pixels) to accommodate non-encrypted participant terminals with weaker display capabilities. This not only reduces the processing burden of non-encrypted participant terminals, but also reduces the amount of data during video transmission, thereby improving transmission efficiency and playback fluency.

The processing of audio streams is equally important. The decrypted audio stream may be encoded in a high bitrate to ensure superior sound quality. However, on the non-encrypted participant terminal, too high a bitrate may cause playback to be jerky or delayed, especially when the network bandwidth is limited. Therefore, the audio stream needs to be bitrate converted. Bitrate conversion refers to adjusting the transmission rate of the audio stream to a suitable range to match the playback capabilities and network environment of the non-encrypted terminal. For example, a high-bitrate audio stream of 320kbps (kilobits per second) is converted to 128kbps to ensure that the non-encrypted participant terminal can smoothly play the audio content in a lower bandwidth environment while maintaining a good sound quality experience.

After completing the resolution conversion and bit rate conversion, the processed audio and video streams can be transmitted to the non-encrypted participant terminals of the video conference. For example, in a multinational company's video conference, if the speaker's video stream is a 1080p high-resolution video, but some participants use non-encrypted participant devices with weak processing capabilities (such as low-end smartphones or old computers), then the above-mentioned resolution and bit rate conversion processing can ensure that all participants can smoothly watch and listen to the speaker's content without being affected by device differences.

The embodiment of the present invention can ensure that the video content can be effectively displayed on various terminals by converting the resolution of the video stream, without causing unsmooth playback due to too high a resolution. This not only improves the user's viewing experience, but also avoids display problems caused by differences in terminal hardware. Converting the bit rate of the audio stream helps to provide a smoother audio experience in different network environments. Whether it is a high-bandwidth network or a low-bandwidth environment, bit rate conversion can ensure that the audio stream is transmitted at an appropriate rate, thereby improving the clarity and coherence of the audio.

Based on the above description of the embodiment of a method for processing a video conference, a hybrid conference processing solution based on a visual network is introduced below. Referring to FIG. 2, a schematic diagram of the principle of a hybrid conference processing solution based on a visual network according to an embodiment of the present invention is shown. The hybrid conference processing solution based on a visual network may involve: a password management server, an integrated management server, a core management server, an encryption terminal, an encryption virtual terminal, a non-encrypted participant terminal, and an encrypted participant terminal. The integrated management server is respectively connected to the password management server and the core management server in communication. The core management server is connected to each terminal of the video conference, including but not limited to an encryption terminal, an encryption virtual terminal, a non-encrypted participant terminal, and an encrypted participant terminal. Among them, the integrated management server is the main platform for conference management services, including autonomous sub-services, conference management sub-services, network management sub-services, etc. The password management server provides services for password-related functions for the integrated management server. The core management server performs registration management and the like for each terminal under the visual network. The core management server is connected to at least one encryption terminal. The encryption terminal is not a participant terminal of a user who logs in to a video conference in a video conference. The encryption terminal supports encryption, decryption, resolution conversion, and other processing. The encryption virtual terminal can be a virtual server. The encryption terminal and the encryption virtual terminal establish a dedicated intercommunication tunnel by sending broadcasts. Specifically, the encryption terminal sends a broadcast to the encryption virtual terminal, the encryption virtual terminal receives the broadcast and responds, and after three handshakes, the encryption terminal and the encryption virtual terminal are connected.

3 , there is shown a schematic diagram of the principle of a solution for processing audio and video streams based on visual networking according to an embodiment of the present invention.

The integrated management client initiates a video conference, sets the encrypted terminal as the host role, and sets an encrypted virtual terminal. Other terminals are the encrypted participant terminal and non-encrypted participant terminal of the logged-in user, and the encrypted participant terminal and non-encrypted participant terminal are ordinary participant roles.

The integrated management server sets the number of codecs for the participant's terminal according to the participant's role, setting the number of codecs for the participant's terminal to 5 and the number of decodes to 8, and setting the number of codecs for the encrypted terminal and encrypted virtual terminal to 8 and the number of decodes to 8. The integrated management server starts the video conference, and the autonomous sub-service pulls the participant's terminal into the video conference.

After each participant terminal joins the conference, the encrypted participant terminal with the ordinary participant role will be tuned to the encrypted terminal's audio and video stream, and the non-encrypted participant terminal will be tuned to the encrypted virtual terminal's audio and video stream. If a non-encrypted participant terminal rejoins the conference after leaving the conference, it does not need to re-tune the stream.

When the encrypted participant terminal switches to the speaking terminal, the scheduling sub-service sends the flow adjustment instruction to the autonomous sub-service, and the autonomous sub-service sends the flow switching instruction to the encrypted terminal and the encrypted virtual terminal to watch the audio and video stream of the speaking terminal, and the non-encrypted participant terminal always watches the audio and video stream of the encrypted virtual terminal.

The encrypted virtual terminal is a virtual encryption server. After receiving the encrypted audio and video stream, it will be decrypted first and then converted into a non-encrypted video stream and non-encrypted audio stream with a resolution of 1080P.
