Example one
Fig. 1 is a flowchart of a video conference method according to an embodiment of the present invention, which is applicable to a video conference through a fixed terminal. The video conference system is particularly suitable for the situation that video conferences are carried out through fixed terminals under the condition of wireless cable connection. The method may be performed by a video conferencing device, which may be implemented in hardware and/or software, which may be configured in an electronic device. As shown in fig. 1, the method includes:
s110, according to the conference participation condition of each video conference and the identification of the candidate participants, determining the conference participants of each video conference from the candidate participants, and determining the conference projection equipment corresponding to each video conference.
It should be noted that, in the present application, the terminal device used for performing the video conference is a fixed terminal, and when the video conference is performed through the fixed terminal, the conference image corresponding to the video conference needs to be projected onto the conference projection device installed in the conference room. A wireless receiving device arranged in the fixed terminal can be adopted to receive the relevant data of the video conference; and sending the relevant data of the video conference by adopting a wireless sending device arranged in the fixed terminal.
The conference participation condition refers to a condition that a conference participant of the video conference needs to have. For example, the conference participation condition may be at least one of an age condition, a job position condition, a working age condition, and a name condition that the participants of the video conference need to possess. The name condition that the participants of the video conference need to have can be the name of the personnel who need to participate in the video conference, which is input in advance by the conference organizer according to the conference requirement.
Candidate participants refer to people who may choose to participate in the video conference as online participants. For example, when a business needs to conduct a video conference, the candidate participants may be all employees within the business. The identity of the candidate participant refers to data that can characterize the identity information of the candidate participant. The identification of the candidate participant may include: the candidate participant's name, age, job title, and working year.

For example, meeting attributes may include: the conference system comprises a large conference, a medium conference and a small conference, wherein 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 the number of participants greater than or equal to 50 can be set as a large conference; the conference attribute of the video conference with the number of the participants more than 20 and less than 50 is a medium conference; the conference attribute of a videoconference with a number of participants less than or equal to 20 is mini-conferences. The number of conference participants corresponding to the conference attribute is only an example, and can be adjusted according to actual needs.
Specifically, the number of participants of each video conference is determined according to the conference participation condition 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: and if the number of the employees in the enterprise with the age less than thirty years old is taken as the number of the participants of the video conference, and the conference attribute of the video conference is determined according to the number of the participants of the video conference.
And S1102, determining conference projection equipment corresponding to each video conference according to the conference attribute of each video conference.
Specifically, the number of participants of the video conference that can be accommodated by different conference projection devices is different. The conference projection equipment and the conference attributes can be stored in the terminal equipment in advance according to the number of participants of the video conference which can be accommodated by the conference projection equipment, and after the conference attributes of each video conference are determined, the conference projection equipment corresponding to each video conference is determined according to the corresponding relation between the conference projection equipment and the conference attributes.
S1103, selecting conference participants of the video conferences from the candidate participants according to the identity marks of the candidate participants and the conference participation conditions of the video conferences.
Specifically, the conference participation condition of each video conference is matched with the identity of the candidate participant, the candidate participants meeting the conference participation condition of each video conference are respectively determined according to the matching result to serve as the conference participants of each video conference, and the identity of each conference participant is associated with the video conference to be participated in.
According to the scheme, the conference attributes of the video conferences can be automatically determined according to the conference participation conditions of the video conferences, conference projection equipment and conference participants corresponding to the video conferences are automatically determined based on the conference attributes and the conference participation conditions of the video conferences, the effect of overall planning of the video conferences according to conference subjects is achieved, and the overall planning efficiency of the video conferences is improved.
And S120, sending a conference invitation to the conference participants, and acquiring video data fed back by the conference participants.
