[0031] Embodiment one

[0032] Figure 1 A flow chart of a video conference method provided for the first embodiment of the present application, the present embodiment can be applicable to the case of video conference through a fixed terminal. Especially applicable to the case of video conference through a fixed terminal in the case of wireless cable connection. The method can be performed by a video conference device, which can be realized in the form of hardware and / or software, and the video conference device can be configured in an electronic device. As shown in the figure, the method comprises: Figure 1

[0033] ​S110, determining the conference participant of each video conference from the candidate participants according to the conference participation condition of each video conference and the identity of the candidate participants, and determining the conference projection device corresponding to each video conference.

[0034] It should be noted that in the present application, the terminal device for conducting a video conference is a fixed terminal, and when conducting a video conference through a fixed terminal, the conference image corresponding to the video conference needs to be projected onto the conference projection device installed in the conference room. The wireless receiving device arranged inside the fixed terminal can be used to receive the relevant data of the video conference, and the wireless sending device arranged inside the fixed terminal can be used to send the relevant data of the video conference.

[0035] The conference participation condition refers to the condition required to be possessed by the conference participant of the video conference. For example, the conference participation condition can be at least one of the age condition, the position condition, the working seniority condition and the name condition required to be possessed by the conference participant of the video conference. The name condition required to be possessed by the conference participant of the video conference can be the name of the personnel required to participate in the video conference which is input in advance by the conference organizer according to the conference demand.

[0036] The candidate participant refers to the personnel who can be selected to participate in the video conference as an online participant. For example, when an enterprise needs to conduct a video conference, the candidate participant can be all the employees in the enterprise. The identity of the candidate participant refers to the data which can represent the identity information of the candidate participant. The identity of the candidate participant can include the name, age, position and working seniority of the candidate participant. The conference projection device refers to the projection device installed in the conference room for playing the video image of the conference participant of the video conference, and each conference room is installed with one conference projection device. The conference participant refers to the participant of the video conference determined from the candidate participants.

[0037] Specifically, when it is required to conduct at least two video conferences through the fixed terminal at the same time, the conference participation condition of each video conference can be input to the fixed terminal. According to the identity of the candidate participants, the conference participants of each video conference meeting the conference participation condition of each video conference are determined from the candidate participants. For example, if the conference participation condition of one of the video conferences is that the personnel with working seniority greater than two years, then according to the identity of the candidate participants, the candidate participants with working seniority greater than two years are selected from the candidate participants as the conference participants of the video conference.

[0038] For example, according to the conference attribute of each video conference, the conference projection device of each video conference can be determined, and according to the conference participation condition of each video conference and the identity of the candidate participants, the conference participant of each video conference can be selected from the candidate participants. Specifically, the following sub-steps can be used to achieve this:

[0039] S1101, determine conference attributes of each video conference according to conference participation conditions of each video conference.

[0040] The conference attribute refers to a conference scale of the video conference corresponding to a number of participants of the video conference. For example, the conference attribute can include a large conference, a medium conference, and a small conference, and the number of participants of the video conference corresponding to different conference attributes is different. For example, the conference attribute of the video conference with more than or equal to 50 participants can be set as a large conference; the conference attribute of the video conference with more than 20 and less than 50 participants can be set as a medium conference; and the conference attribute of the video conference with less than or equal to 20 participants can be set as a small conference. The number of conference participants corresponding to the above conference attribute is only an example, and can be adjusted according to actual needs.

[0041] Specifically, the number of participants of each video conference is determined according to the conference participation conditions of each video conference, and the conference attribute of each video conference is determined according to the number of participants of each video conference. For example, if the conference participation condition of the video conference is that the employees in the enterprise who are less than thirty years old, the number of employees in the enterprise who are less than thirty years old is taken as the number of participants of the video conference, and the conference attribute of the video conference is determined according to the number of participants of the video conference.

[0042] S1102, determine the conference projection device corresponding to each video conference according to the conference attribute of each video conference.

[0043] Specifically, different conference projection devices can accommodate different numbers of participants of the video conference. The conference projection device and the conference attribute can be pre-stored in the terminal device according to the number of participants of the video conference that the conference projection device can accommodate, and the conference projection device corresponding to each video conference is determined according to the corresponding relationship between the conference projection device and the conference attribute after the conference attribute of each video conference is determined.

[0044] S1103, select conference participants of each video conference from the candidate participants according to the identity of the candidate participant and the conference participation condition of each video conference.

[0045] Specifically, the conference participation condition of each video conference is matched with the identity of the candidate participant, and according to the matching result, the candidate participant who meets the conference participation condition of each video conference is determined as the conference participant of each video conference, and the identity of each conference participant is associated with the video conference to be participated.

[0046] It can be understood that the above scheme can automatically determine the conference attributes of each video conference according to the conference participation conditions of each video conference, to automatically determine the conference projection device and the conference participant corresponding to each video conference based on the conference attributes and the conference participation conditions of each video conference, to realize the effect of overall planning of video conferences according to the conference theme, and to improve the overall planning efficiency of video conferences.

[0047] S120, send a conference invitation to the conference participant, and obtain video data fed back by the conference participant.

[0048] The conference invitation includes the conference start time, the conference end time, the conference theme, and the device identifier of the conference projection device corresponding to the conference participant. The device identifier of the conference projection device can be a number, an image or a string; for example, the device identifier can be the room number of the conference room where the conference projection device is located. The conference theme refers to the summary information that can represent the conference content of the video conference. The video data fed back by the conference participant includes the identity identifier of the conference participant and the image data of the conference participant collected by the camera device.

[0049] Specifically, the conference invitation is sent to the conference participant, so that the conference participant determines the conference start time, the conference end time, the conference theme and the device identifier of the conference projection device corresponding to the conference participant of the video conference to be participated according to the conference invitation. The video data fed back by the conference participant is obtained in real time within the time period between the conference start time and the conference end time.

[0050] S130, analyze the video data to obtain the video image of the conference participant and the identity identifier of the conference participant.

[0051] Specifically, the video data is analyzed, and the identity identifier of the conference participant and the video image of the conference participant that can be displayed on the fixed terminal are obtained according to the analysis result of the video data.

[0052] S140, according to the device identifier of the conference projection device, the video image is encrypted to obtain an encrypted image, and according to the identity identifier of the conference participant, the encrypted image is sent to the conference projection device to control the conference projection device to decrypt the encrypted image to generate a conference image.

[0053] Specifically, according to the identity of the conference participant, the video conference that the conference participant is to participate in is determined, and the device identifier of the conference projection device corresponding to the video conference that the conference participant is to participate in is acquired. The device identifier of the conference projection device is taken as encrypted data of the video image, and the video image is encrypted according to the encrypted data to obtain an encrypted image. According to the identity of the conference participant, the encrypted image corresponding to the conference participant is sent to the conference projection device corresponding to the video conference that the conference participant is to participate in. The conference projection device can decrypt the encrypted image based on a pre-specified decryption protocol to obtain the video image of the conference participant. The conference projection devices of each video conference respectively integrate the video images of the conference participants obtained to obtain the video images of the conference participants after integration as the conference images of each video conference.

[0054] Exemplarily, the encrypted transmission of the video image can be implemented through the following sub-steps:

[0055] S1401, generating a temporary key according to the device identifier of the conference projection device and the digest information of the video image.

[0056] The digest information of the video image can be part of the data of the video image, for example, can be the header data of the video image or the feature data of the video image extracted by a feature extraction algorithm.

[0057] Specifically, the digest information of the video image is extracted from each video image, and a key server is used to generate a temporary key corresponding to each video conference according to the device identifier of each conference projection device and the digest information of each video image. The temporary key includes a temporary private key and a temporary public key. The key server assigns the temporary private key in the temporary key to the terminal device, and assigns the temporary private key in each temporary key to the conference projection device corresponding to the temporary key.

[0058] S1402, encrypting the video image using the temporary private key in the temporary key to obtain an encrypted image.

[0059] Specifically, the temporary private key in the temporary key corresponding to each video conference is used to encrypt each video image to obtain the encrypted image of each video image.

[0060] S1403, according to the identity of the conference participant, the encrypted image is sent to the conference projection device, and the conference projection device is controlled to decrypt the encrypted image by the temporary private key in the temporary key to generate a conference image.

[0061] Specifically, according to the identity of the conference participant, the encrypted video corresponding to the conference participant is sent to the conference projection device corresponding to the video conference that the conference participant participates in. The conference projection device decrypts the encrypted video according to the temporary private key in the temporary key, and obtains the video of the conference participant. The conference projection device of each video conference integrates the video of the conference participant obtained, and takes the integrated video of the conference participant as the conference video of each video conference.

[0062] It can be understood that the temporary key is generated according to the device identifier of the conference projection device and the digest information of the video, so as to encrypt the video into an encrypted video through the temporary key, and control the conference projection device to decrypt the encrypted video through the temporary key to obtain the conference video. The problem that the video projection device projects the wrong video when the video is sent to different conference projection devices at the same time can be avoided. The security of the video conference and the accuracy of the conference video played by the conference projection device are ensured.

[0063] S150, obtaining the conference video fed back by the conference projection device, and sending the conference video to the conference participant according to the identity of the conference participant.

[0064] Specifically, the conference video of each video conference fed back by each conference projection device is obtained, the identity of the conference participant corresponding to each video conference is determined, and the conference video of each video conference is sent to the conference participant of each video conference according to the identity of the conference participant.

[0065] The above scheme solves the problem that when the video conference is performed through the fixed terminal, in order to enable the fixed terminal to have the function of the video conference, complex cable connection needs to be performed in advance, and the cable knot phenomenon is easy to occur, which leads to the difficulty in cable maintenance. At the same time, the problem that the video is easy to be stolen in the process of the video conference, thereby leading to information leakage is solved.

[0066] The technical scheme provided by the embodiment determines the conference projection device corresponding to each video conference according to the conference participation condition of each video conference and the identity of the candidate participant, and determines the conference participant of each video conference from the candidate participant; sends a conference invitation to the conference participant, and obtains video data fed back by the conference participant; analyzes the video data to obtain the video image of the conference participant and the identity of the conference participant; encrypts the video image according to the device identity of the conference projection device to obtain an encrypted image, and sends the encrypted image to the conference projection device according to the identity of the conference participant, controls the conference projection device to decrypt the encrypted image to generate a conference image; obtains the conference image fed back by the conference projection device, and sends the conference image to the conference participant according to the identity of the conference participant. The above scheme determines the conference projection device and the conference participant of each video conference through the conference participation condition of each video conference and the identity of the candidate participant, and respectively sends the video data fed back by the conference participant to the conference projection device corresponding to the video conference participated by the video participant after encryption, so that the conference projection device corresponding to each video conference respectively obtains the video image corresponding to each video conference after decrypting the video data, and feeds back the video image corresponding to the video conference to the conference participant. When there are multiple video conferences under the premise of wireless cable connection, the video data of each video conference is received by the fixed terminal to realize simultaneous overall planning of multiple video conferences, the video data of each video conference is accurately sent to the conference projection device corresponding to each video conference, and the video image fed back by the conference projection device is accurately fed back to the conference participant, thereby improving the conference planning efficiency of the video conference. Meanwhile, the video image is sent to the conference projection device after encryption, which can avoid the content in the video image being stolen, thereby improving the security of the video conference.

[0067] Embodiment two

[0068] Figure 2 The flowchart of the video conference method provided by the embodiment two of the application is based on the optimization of the above-mentioned embodiment, and an optimal implementation scheme of obtaining the video data fed back by the conference participant, sending the encrypted image to the conference projection device according to the identity of the conference participant, and controlling the conference projection device to decrypt the encrypted image to generate a conference image is given. Specifically, as shown in Figure 2 The method comprises the following steps.

[0069] S210, according to the conference participation condition of each video conference and the identity of the candidate participant, determine the conference projection device corresponding to each video conference, and determine the conference participant of each video conference from the candidate participant.

[0070] S220, send a conference invitation to the conference participant, call the data conversion interface of the intermediate server, and convert the feedback data according to the first data conversion protocol to obtain the video data fed back by the conference participant.

[0071] It should be noted that due to the difference in the model of the camera equipment used by different conference participants, the terminal device may not be able to directly analyze the feedback data of the conference participant to obtain the video image of the conference participant. Therefore, the intermediate server for data conversion is set.

[0072] The first data conversion protocol refers to a protocol for converting the data format of the feedback data of the conference participant into a data format that can be analyzed by the fixed terminal.

[0073] Specifically, the conference invitation is sent to the conference participant, and after obtaining the feedback data of the conference participant, the data conversion interface of the intermediate server is called, and the feedback data is converted according to the first data conversion protocol, and the converted feedback data is taken as the video data fed back by the conference participant.

[0074] S230, analyze the video data to obtain the video image of the conference participant and the identity of the conference participant.

[0075] S240, according to the device identifier of the conference projection device, the video image is encrypted to obtain an encrypted image, and according to the identity of the conference participant, the encrypted image is sent to the conference projection device to control the conference projection device to decrypt the encrypted image to obtain decrypted data.

[0076] S250, control the conference projection device to call the data conversion interface of the intermediate server, and convert the decrypted data according to the second data conversion protocol, and obtain the conference image according to the data conversion result.

[0077] Due to the difference in the model of the conference projection device installed in each conference room, some conference projection devices may not be able to obtain the video image of the conference participant according to the decrypted data. Therefore, the intermediate server is needed to convert the decrypted data.

[0078] The second data conversion protocol refers to a protocol for converting the data format of the decrypted data into a data format that can be analyzed by the conference projection device.

[0079] Specifically, the conference projection device is controlled to call the data conversion interface of the intermediate server, and the decrypted data is converted according to the second data conversion protocol, and the converted decrypted data is analyzed to obtain the video image of the conference participant. The conference projection device integrates the obtained video image of the conference participant to generate a conference image.

[0080] S260, acquire the conference image fed back by the conference projection device, and send the conference image to the conference participant according to the identity of the conference participant.

[0081] The technical scheme of the embodiment, after acquiring the feedback data of the conference participant, calls the data conversion interface of the intermediate server to convert the feedback data, converts the feedback data into video data recognizable by the fixed terminal, and acquires the video image of the conference participant according to the video data; the video image is encrypted and sent to the conference projection device, the conference projection device decrypts the encrypted image to obtain decryption data, calls the data conversion interface of the intermediate server to convert the decryption data, and obtains the conference image that can be displayed on the conference projection device. The above scheme avoids the situation that the fixed terminal cannot recognize the feedback data of the conference participant due to different camera equipment used by the conference participant, and avoids the problem that the conference projection device cannot play the video image sent by the fixed terminal due to different formats of videos that can be played by different models of conference projection devices. By setting the intermediate server to convert the transmission data in the video conference, it is realized that when the video conference is conducted through the fixed terminal, the data format of the feedback data of the conference participant does not need to be considered, and the device model of the conference projection device does not need to be considered, and the compatibility of the video conference to the conference projection device and the image acquisition device is improved.

Specifically, as shown in the figure, Figure 3 The method comprises the following steps:

[0084] S310, according to the conference participation condition of each video conference and the identity of the candidate participant, determine the conference projection device corresponding to each video conference, and determine the conference participant of each video conference from the candidate participant.

[0085] S320, send a conference invitation to the conference participant, and acquire the video data fed back by the conference participant.

[0086] S330, analyze the video data to obtain the video image of the conference participant and the identity of the conference participant.

[0088] S350, obtain the conference image fed back by the conference projection device, and send the conference image to the conference participant according to the identity identifier of the conference participant.

[0089] S360, when there is a conference adjustment requirement, determine a target conference to be adjusted and a target participant of the target conference from the video conferences according to a conference adjustment rule.

[0090] The conference adjustment requirement refers to an adjustment requirement for a conference participant of a video conference during the process of the video conference. The conference adjustment rule can include a conference adjustment time, a device identifier of a conference projection device corresponding to the target conference to be adjusted, and a target participant of the target conference after adjustment. The target conference refers to a video conference that needs to be adjusted in terms of conference participants. The target participant refers to a conference participant required by the target conference after adjustment.

[0091] Specifically, the conference organizer can pre-set the conference adjustment rule. When the conference adjustment time specified in the conference adjustment rule is reached, there is a conference adjustment requirement. According to the conference adjustment rule, the device identifier of the conference projection device corresponding to the target conference to be adjusted and the identity identifier of the target participant of the target conference are determined from the video conferences.

[0092] S370, if there is an absent participant who does not participate in the target conference in the target participant, the identity identifier of the absent participant is obtained, and the video image of the absent participant is obtained according to the identity identifier of the absent participant.

[0093] Specifically, the identity identifier of the current participant of the target conference is determined, and the current participant is a conference participant participating in the target conference at the current time. According to the identity identifier of the current participant and the identity identifier of the target participant, it is determined whether there is an absent participant who does not participate in the target conference in the target participant. If there is an absent participant who does not participate in the target conference in the target participant, the identity identifier of the absent participant is determined according to the comparison result of the identity identifier of the current participant and the identity identifier of the target participant, and the video image of the absent participant is obtained according to the identity identifier of the absent participant.

[0094] S380, migrate the video image of the absent participant to the target projection device corresponding to the target conference, and generate an adjustment image according to the target projection device.

[0095] The target projection device refers to a conference projection device used for performing a target conference, and the adjusted image refers to a conference image of the target conference after adjustment.

[0096] Specifically, a device identifier of a target projection device corresponding to the target conference is determined, and the video image of the absent participant is migrated to the target projection device corresponding to the target conference according to the device identifier of the target projection device, so that the target projection device generates an adjusted image according to the video image of the target participant.
