S230-1, if the first display device and the second display device exist completely, establishing communication connection between the first display device and the second display device.
And S230-2, if the data does not exist completely, not establishing the communication connection between the first display equipment and the second display equipment.
As an example, after a certain person a inputs request information such as a conference subject name, conference subject time, an account name, and an account password on a display device B (i.e., a second display device) used by the person a, a controller C connected to the display device B may generate a communication access request of the display device B according to the request information such as the conference subject name, the conference subject time, the account name, and the account password input by the person a; meanwhile, the controller C acquires, from the server, authentication information stored in the server by the display device D (i.e., the first display device) used by the speaker based on the generated communication access request, compares the acquired authentication information with the request information input by the person a, and determines whether all of the conference subject name, the conference subject time, the account name, and the account password in the request information input by the person a exist in a directory corresponding to the authentication information, i.e., determines whether the request information input by the person a exists in the corresponding directory in the authentication information; if the communication link exists completely, the description personnel A is in accordance with the conference meeting conditions, the marker personnel A are the conference meeting personnel who participate in the online conference, then the controller C sends an instruction to the router, the router determines the corresponding communication link according to the communication protocol supported by the display equipment B and the display equipment D, and then the communication connection between the two display equipment is established according to the corresponding communication link. If one or more items of the request information input by the person a cannot find the corresponding directory in the verification information, for example, the conference subject name input by the person a cannot find the conference subject name in the directory of the verification information, the person a is considered to be not in accordance with the conference participating condition, the marker person a is not a conference participant who participates in the online conference, and meanwhile, the controller C does not send an instruction to the router, that is, the communication connection between the display device B and the display device D is not established. The embodiment determines whether a person meets the meeting conditions by judging the request information input by the person on the display equipment used by the person, and judges whether the person is a meeting person, so that the situation that the person who participates in the meeting is a person who reports in advance can be ensured, and the interference of the person who does not have any trouble to the meeting is avoided.
In an exemplary embodiment, the process of determining whether the first display device is in the sharing state includes: after the first display device and the second display device establish communication connection, judging whether the first display device sends ciphertext information to the second display device or not and whether the second display device receives the ciphertext information or not; the ciphertext information comprises: a key session feature code, an authentication certificate of the first display device, and a digital signature of the first display device. If the second display device receives the ciphertext information sent by the first display device, judging that the first display device is in a sharing state; and if the first display device does not send the ciphertext information to the second display device, or the second display device does not receive the ciphertext information sent by the first display device, determining that the first display device is in a non-sharing state. In an embodiment, after the first display device establishes a communication connection with the second display device, the first display device may send ciphertext information such as a key session feature code, an authentication certificate of the first display device, and a digital signature of the first display device to the second display device, then the second display device performs authentication according to the ciphertext information such as the key session feature code, the authentication certificate, and the digital signature sent by the first display device, and establishes a session after the authentication is successful, that is, a sharing state of the first display device is determined according to a session state of the first display device and the second display device. If a session does not exist between the first display device and the second display device, namely the first display device does not send ciphertext information to the second display device, or the second display device does not receive the ciphertext information sent by the first display device, the first display device is judged to be in a non-sharing state, and at the moment, the display content on the first display device is only displayed locally and cannot be shared to the second display device; and if the second display device receives the ciphertext information sent by the first display device, the first display device is defaulted to be in a shared state, and at the moment, the display content on the first display device can be shared to the second display device in real time for displaying. In this embodiment, by determining the sharing state of the first display device, it can be determined whether the conference content shared by the speaker can be synchronously displayed on the display devices used by other participants, so as to avoid the situation that the speaker continuously explains the conference content, and the participants do not receive the shared conference explanation content.
In an exemplary embodiment, in the process of transmitting the formed data packet to the second display device according to the corresponding communication link, the method further includes: and grouping the communication links after the communication connection is established, and dividing the communication links into a transmission communication link and a standby communication link. And acquiring the transmission time length of the data packet on a transmission communication link, comparing the transmission time length with a preset time length, and judging whether the transmission time length is less than or equal to the preset time length. If the transmission time length is less than or equal to the preset time length, continuing to transmit the data packet to the second display equipment through the transmission communication link; and if the transmission duration is longer than the preset duration, calling the standby communication link, and transmitting the data packet to the second display device by using the transmission communication link and the standby communication link together. The embodiment firstly groups communication links into a transmission communication link and a standby communication link; if the duration of transmitting the data packet by using the transmission communication link is less than or equal to the preset duration, the bandwidth owned by the current transmission communication link is greater than or equal to the bandwidth required by transmitting the data packet; if the duration of transmitting the data packet by using the transmission communication link is longer than the preset duration, the bandwidth owned by the current transmission communication link is smaller than the bandwidth required by transmitting the data packet, so that the bandwidth of transmitting the data packet can be increased by calling the standby communication link, and the transmission duration of the data packet is ensured to be stabilized within a range. The preset duration may be determined according to a bandwidth corresponding to an actual communication link. In the embodiment, all the communication links are grouped and then transmitted with the data packet, so that not only can the data packet be transmitted, but also the bandwidth can be reduced while the data packet is transmitted, and the flow used when the display content is shared can be reduced.
In an exemplary embodiment, as shown in fig. 3, the data transmission method further includes: s300, acquiring the display content of the first display device at the current moment and before the current moment.
And S310, acquiring the display content created by the second display device at the current moment.
S320, comparing the display content created by the second display device at the current time with the display content of the first display device at the current time and before the current time, and determining whether there is a time delay in the communication between the first display device and the second display device.
S320-1, if the display content created by the second display device at the current time is the same as the display content of the first display device at the current time, there is no time delay in the communication between the first display device and the second display device.
S320-2, if the display content created by the second display device at the current time is the same as the display content of the first display device before the current time, there is a time delay in the communication between the first display device and the second display device.
In this embodiment, by comparing the display content of the second display device at the current time with the display of the first display device at the current time and before the current time, it can be determined whether the second display device can display the content shared by the first display device in real time, and if the content cannot be displayed in real time, it indicates that a certain time delay exists between the sharing of the first display device and the sharing of the second display device. If time delay exists between the first display device and the second display device, the time delay time of all the participants can be unified, and the same display content can be seen by all the participants at the same time, so that the situation that part of the participants can not participate in discussion and communication of the conference in real time due to the time delay is avoided.
In accordance with the above, in some exemplary embodiments, the display content in the first display device includes: textual content, image content, and/or video content. As an example, if the display content in the first display device is text content, after the first display device establishes a communication connection with the second display device, determining whether the first display device is in a sharing state; when the first display device is in a sharing state, the encoder encodes the text content in the first display device to form a data packet, wherein the encoder is connected with the first display device; transmitting the formed data packet to a second display device according to a corresponding communication link; and after the transmission is finished, the decoder connected with the second display equipment starts to decode the transmitted data packet, and creates and displays the same text content as the first display equipment on the second display equipment according to the decoding result.
