At step S300, the host user device may initiate an online conference utilizing various platforms that provide online conference software. In one embodiment, various platforms may include ZOOM, Google Meet, MS Teams, Cisco Webex, etc. Additionally, the host user device may simultaneously initiate an online conference and participate in an online conference.

In step S302, at least one user device 104-110 may participate in an online conference initiated by the host user device.

In step S304, user devices 104-110 participating in the online meeting may activate the online meeting recording function. When the user device 104-110 activates the online meeting recording function, the user device 104-110 generates meeting data while the online meeting is in progress and stores it in local storage within the user device 104-110, Meeting data stored in local storage can be transmitted to the server 102 through the network 112.

In step S306, at least one user device 104-110 participating in the online conference may exchange conference data in real time with other user devices participating in the online conference through the server 102.

In step S308, the server 102 determines whether the loss rate of conference data received from at least one user device 104-110 participating in the online conference exceeds a threshold while the online conference is in progress. You can.

In step S310, when the server 102 determines that the loss rate of conference data of at least one user device 104-110 exceeds the threshold, the server 102 measures the loss rate exceeding the threshold. It can be determined whether the available bandwidth of the network between the user devices 104-110 is sufficient.

In step S312, if the server 102 determines that the available bandwidth of the network between the server 102 and the user devices 104-110 for which a loss rate exceeding the threshold is measured is sufficient, the server ( The conference data of the corresponding user device stored in the memory 204 of 102) can be updated.

In step S314, the server 102 determines that the loss rate of conference data for at least one user device 104-110 is below the threshold or the availability of the server 102 and the user device 104-110 If it is determined that the bandwidth is not sufficient, the meeting data stored in the memory 204 of the server 102 may be maintained.

Server 102 may provide the online meeting recording file only to the host user device or to all of at least one user device participating in the online meeting.

The present disclosure relates to a device or a method of operating the same that provides online meeting recording with high visual and sound quality to users participating in the online meeting.

According to the above series of steps (S300-S320), the online conference server 102 can update data received from the user device in real time during a certain period of time when the network was unstable during the online conference. As a result, at least one user device that participates in the online meeting and activates the online meeting recording function can be provided with an online meeting recording with high visual and audio quality.

One embodiment may update meeting data stored in server 102 based on state measurements of network 112. Examples of methods for measuring the state of the network 112 include measuring the loss rate of data transmitted by a user device or measuring the bandwidth of the network. However, the method for measuring the state of the network is not limited to the above example, and the state of the network 112 can be measured in various ways.

FIG. 4 is a flowchart specifically explaining an operation in which the server 102 updates conference data in real time according to an embodiment.

In one embodiment, server 102 may perform the following series of steps.

In step S402, the server 102 may receive conference data from at least one user device 104-110 participating in the online conference.

Here, for convenience of explanation, the meeting data received by the server 102 from at least one user device is hereinafter referred to as “first meeting data.” “First session data” is distinguished from “second session data” below.

In step S404, the server 102 may store the first data received from the user devices 104-110.

“First meeting data” means meeting data stored on server 102 before being updated, and includes meeting data received from at least one user device 104-110 when network 112 is in an unstable state. can do. The server 102 may store not only meeting data but also at least one command executed by the server 102.

In step S406, server 102 may measure a loss rate of data received over network 112 from at least one user device 104-110.

Server 102 may measure the loss rate over time, and may measure the loss rate each time it receives conference data from a user device 104-110. Additionally, server 102 may measure the loss rate for each of all user devices 104-110 participating in the online conference. The loss rate represents the degree of loss of conference data exchanged through the network 112 between the user devices 104-110 participating in the online conference and the server 102.

In one embodiment, the server 102 may receive information indicating the number of packets of first data transmitted by at least one user device. The server 102 can determine the number of packets that the server 102 did not receive, based on the above information. The server 102 may measure the loss rate by dividing the number of packets not received by the server 102 by the number of packets of the first data transmitted by the at least one user device.

The section in which the loss ratio is measured to be large refers to the section in which the network 112 between the user devices 104-110 and the server 102 is in an unstable state. Conference data received from the user device 104-110 through an unstable network may be of low quality (eg, low image quality, low sound quality).

According to an embodiment of the present disclosure, conference data (i.e., conference data of low quality (low image quality, low sound quality)) received in a section in which a large loss ratio is measured is updated in real time while the online conference is in progress, After the meeting ends, high quality (high definition, high sound quality) online meeting records can be provided to users who participated in the online meeting.

In step S408, server 102 may identify user devices whose loss rate exceeds a predetermined threshold.

As the server 102 measures the loss rate for each user device 104 - 110 in real time, among at least one user device 104 - 110 that participated in the online conference and transmitted conference data to the server 102 , user devices for which a loss rate exceeding a predetermined threshold has been measured can be identified.

The threshold value is a set value predetermined by at least one command in the server 102, and its value may vary depending on various factors, including the state of the network 112. In one embodiment, the threshold may be set at 50%. Server 102 may identify user devices with a loss rate exceeding 50%. However, this is only a value set as an example, and the threshold value is not limited as set as an example.

In step S410, the server 102 may request the identified user device to transmit second meeting data including meeting data stored in the identified user device in the section in which the loss rate exceeds the threshold.

Here, 'section' may mean a section according to time. For example, referring to FIG. 5, the section T2 to T3 502 may correspond to the section.

In one embodiment, the server 102 transmits the second conference data to the identified user device based on the identification information of the conference data stored in the server 102 in the section where the loss rate exceeds a predetermined threshold. You can request .

Here, 'meeting data identification information' may include a sequence number for controlling the order of data, and includes other information for identifying data. The server 102 may transmit a request message through the network 112 when requesting transmission of the second meeting data to the identified user device.

“Second session data” is distinct from “first session data.” The second meeting data refers to meeting data generated in at least one user device 104-110 and stored before being transmitted to the server 102 through the network 112. The second meeting data may be high quality (high image quality, high sound quality) data that is not affected by the state of the network 112.

The second meeting data may include meeting data stored in the identified user device in a section where the loss rate exceeds a predetermined threshold. However, the second meeting data only includes meeting data stored in the identified user device in the section where the loss rate exceeds a predetermined threshold, and does not mean all of the meeting data stored in the identified user device.

In step S412, server 102 may receive a second round of data from the identified user device.

In step S414, the server 102 may update the previously stored first meeting data using the second meeting data.

In one embodiment, the server 102 provides the same identification information as the conference data received in the section in which the loss rate exceeds a predetermined threshold, based on the identification information of the conference data included in the received second conference data. Only data that has branches can be extracted. The server 102 may replace only the data received in the section in which the loss rate exceeds a predetermined threshold among the previously stored first data with the extracted data.

In one embodiment, if the loss rate does not exceed a predetermined threshold (less than the threshold), the server 102 may maintain the previously stored first data as is without updating it.

A section in which the loss ratio does not exceed a predetermined threshold (is less than the threshold) means a section in which the network 112 is in a stable state, so conference data received through the network in a stable state is of high quality (e.g., high definition). , high sound quality), the purpose of the present disclosure can be achieved even if the pre-stored meeting data is kept as is.

Following a series of steps (S402-S414), the server 102 updates pre-stored meeting data in real time while the online meeting is in progress, and after the online meeting ends, at least one user device 104 participating in the online meeting -110), it is possible to provide online meeting records with high visual and sound quality.

FIG. 5 is a diagram illustrating a case where a loss ratio exceeds a threshold value according to an embodiment.

The graph 500 in FIG. 5 is a graph in which the server 102 measures the loss rate of conference data received from user device 1 among the user devices 104-110 participating in the online conference while the online conference is in progress. Yes.

The horizontal axis of the graph 500 represents time, and the vertical axis represents loss rate. T1 is the time when the online meeting starts, T2 and T3 are each a point during the online meeting, and T4 is the time when the online meeting ends. (T1 to T4 are used with the same meaning in the following specifications) .

In the graph 500, the T2 to T3 section 502 is a section in which the loss rate of conference data received from user device 1 exceeds the threshold, and the network 112 between user device 1 and the server 102 is unstable. It corresponds to the section in .

The server 102 sends messages to user device 1 in the T2 to T3 section 502 in order to update the first meeting data received from user device 1 in the T2 to T3 section 502 in real time while the online conference is in progress. User device 1 may be requested to transmit second meeting data including stored meeting data.

Server 102 may receive second conference data from user device 1. The server 102 may update the previously stored first meeting data using the second meeting data.

FIG. 6 is a diagram illustrating an example of an operation in which a server updates conference data in real time, according to an embodiment.

Referring to Figure 6, user device N (N=1, 2, 3,??N) may be one of the user devices 104-110 participating in the online conference. Hereinafter, for convenience of explanation, it is assumed that user device 1 has measured a section in which the loss ratio exceeds the threshold, and that user devices other than user device 1 have loss ratios that have been measured below the threshold.

The server 102 stores first meeting data 600, 606, and 608, and the first meeting data 600 includes meeting data 6100 received from user device 1 in the section T2 to T3 (502). can do. Conference data 6100 is conference data received by the server 102 from user device 1 in the T2 to T3 section 502, and may be conference data of low quality (low image quality, low sound quality).

Additionally, second meeting data 602 is stored in user device 1, and the second meeting data 602 may include meeting data 6200 stored in user device 1 in the T2 to T3 section 502. Meeting data 6200 is meeting data stored in user device 1 before being transmitted to the server 102 through the network, and may be high quality (high picture quality, high sound quality) meeting data that is not affected by network conditions.

The server 102 may measure (500) the conference data loss rate of each user device in real time while the online meeting is in progress and identify user device 1 for which the loss rate is measured exceeding the threshold.

In step S601, the server 102 requests the identified user device 1 to transmit the second meeting data 602 including the meeting data 6200 stored in the user device 1 in the period T2 to T3 502, Second meeting data 602 may be received. Here, the second meeting data 602 suffices to include the meeting data 6200 and should not be interpreted to mean the entire meeting data stored in user device 1.

In step S603, the server 102 may update the first meeting data 600 using the second meeting data 602 received from user device 1. Server 102 may store user device 1's meeting data 604, including updated meeting data 6300.

The server 102 may request transmission of the second meeting data 602 to user device 1 based on the identification information of the meeting data 6100 previously stored in the T2 to T3 section 502. Here, the meeting data identification information may include a sequence number for controlling the order of data, and includes other information for identifying data. The server 102 may transmit a request message through the network 112 when requesting transmission of the second meeting data 602 to user device 1.

The server 102 provides the same identification information as the conference data 6100 received in the section T2 to T3 502, based on the conference data identification information included in the second conference data 206 received from user device 1. It is possible to extract only the data and, of the first data 600, only the data 6100 received in the section T2 to T3 (502) can be replaced with the extracted data.
