[0052] Currently, to operate the large-screen conference terminal 102 (i.e., a large-screen video conference device), an external device such as a mouse, a keyboard, or a remote controller is often needed. However, the external device or the remote controller has the following disadvantages: on the one hand, the large-screen conference terminal 102 is arranged at a fixed position and cannot be moved at will, so the user can only operate the large-screen conference terminal 102 at the fixed position and cannot operate the large-screen conference terminal 102 at any time and any place, which is inconvenient; on the other hand, to click a certain function on the software, the user often needs to operate multiple times to meet the requirement, which is not only inconvenient but also seriously affects the user's experience and wastes a lot of time, resulting in low conference efficiency.

[0053] To solve the above problems, the present application provides a method for controlling a large-screen video conference system, which can be applied to an application environment as shown in Figure 1 Figure 1 is a schematic diagram of an application environment of the method for controlling a large-screen video conference system according to an embodiment of the present application, as shown in Figure 1 The large-screen conference terminal 102 and the master terminal 104 communicate in a local area network. Figure 2 is a first flowchart of the method for controlling a large-screen video conference system according to an embodiment of the present application, as shown in Figure 2 ​As shown, in an embodiment of the present application, the present application provides a method for controlling a large-screen video conference system, which is applied to a large-screen conference terminal 102, and the method comprises the following steps:

[0054] In step S201, when a broadcast message sent by the master terminal 104 is received in the local area network, a first IP address and a first port number are returned, wherein the first IP address and the first port number are the IP address and the port number of the large-screen conference terminal 102, and the broadcast message carries a second IP address and a second port number, and the second IP address and the second port number are the IP address and the port number of the master terminal 104;

[0055] In step S202, when a check code sent by the master terminal 104 is received, the check code is checked.

[0056] In step S203, when the check is successful and the connection with the master terminal 104 is established, a video image is acquired, and the video image is sent to the master terminal 104, wherein the video image is a video image compressed by the H264 algorithm; wherein the video image can be acquired by creating an instance (for example, the name of the video acquisition instance is VirtualDisplay) through the MediaProjectionManager mediaProjectionManager function and the createVirtualDisplay function of the Android system of the large-screen conference terminal 102 to acquire the video, and obtaining the corresponding video image based on the video, of course, in some other embodiments, the video image can also be acquired in other ways, which is not limited here; since the storage space occupied by the video image is very large, the video image is compressed by the H264 algorithm in this step; in this way, it is not only beneficial to the transmission and permanent storage of the video image, but also improves the security. In addition, the H264 algorithm is an existing algorithm and the working principle of the H264 algorithm is known to those skilled in the art, so it is not described here.

[0057] In step S204, when an operation control instruction sent by the master terminal 104 is received, the operation control instruction is executed. That is, when the control terminal is operated, the corresponding operation instruction is sent to the large-screen conference terminal 102, and when the operation control instruction sent by the master terminal 104 is received by the large-screen conference terminal 102, the operation control instruction is executed, without the need for external equipment or the need to connect to the Internet, in a pure intranet (i.e. local area network) environment, by operating a master terminal 104, the large-screen conference terminal 102 can be directly controlled to execute the operation control instruction, so that the operation on the master terminal 104 (i.e. the control terminal) directly reflects on the large-screen conference terminal 102 (i.e. the large-screen video conference device), in this way, the complexity of the operation is reduced and the convenience of the operation is improved.

[0058] Through the steps S201 to S204, first, the large-screen conference terminal 102 returns the first IP address and the first port number when receiving the broadcast message sent by the host terminal 104 in the local area network, then the large-screen conference terminal 102 checks the check code when receiving the check code sent by the host terminal 104, and then in the case of successful check and connection with the host terminal 104, the large-screen conference terminal 102 acquires the video image and sends the video image to the host terminal 104. In addition, since the video image is a video image compressed by the H264 algorithm, it is not only beneficial to the transmission and permanent storage of the video image, but also improves the security. Finally, when the large-screen conference terminal 102 receives the operation control instruction sent by the host terminal 104, the operation control instruction is executed. Compared with the previous way of operating the large-screen conference terminal 102 by using a mouse or a keyboard, which can only be operated in a fixed position and cannot be operated anytime and anywhere, the operation convenience is low. The embodiment does not need external equipment, and when the corresponding operation is performed on the host terminal 104 (also called control terminal) in the range of the local area network, the host terminal 104 sends the corresponding operation instruction to the large-screen conference terminal 102. When the large-screen conference terminal 102 receives the operation control instruction sent by the host terminal 104, the operation control instruction is executed. This process does not require external equipment (i.e. does not require external mouse or keyboard) and does not require Internet connection. In a pure intranet (i.e. local area network) environment, by operating a host terminal 104, the large-screen conference terminal 102 can be directly controlled to execute the operation control instruction, so that the operation on the host terminal 104 is directly reflected on the large-screen conference terminal 102 (i.e. large-screen video conference equipment). In this way, the operation complexity is reduced, the operation convenience is improved, and the problem of high operation complexity and low operation convenience in the related art by using external equipment such as a mouse, a keyboard, or a remote controller to operate the large-screen conference terminal 102 is solved. On the other hand, due to the convenient operation, a lot of time is saved, the efficiency of the conference is improved, and the user has a good operation experience.

[0059] Figure 3 is a second flowchart diagram of the method for controlling the large-screen video conference system according to the embodiments of the present application, as shown in Figure 3 In the related art, the large-screen video conference equipment (i.e. large-screen conference terminal 102) can only be operated in a fixed position and cannot be operated anytime and anywhere. When the large-screen conference terminal 102 is operated by using a mouse or a keyboard, it can only be operated in a fixed position and cannot be operated anytime and anywhere, and the operation convenience is low. In order to improve the operation convenience, before the operation control instruction sent by the host terminal 104 is received and the operation control instruction is executed, the method further includes the following steps:

[0060] The master terminal 104 receives the video image;

[0061] The video image is decompressed, and the decompressed video image is displayed; thus, within the scope of the local area network, it is convenient to view and operate at any time and anywhere;

[0062] The master terminal 104 sends the operation instruction to the large-screen conference terminal 102 when receiving the operation instruction, wherein the operation instruction at least includes a click instruction. For example, if the user wants to realize a certain function on the software, the user can directly click a certain function button of the large-screen conference terminal 102, and the large-screen conference terminal 102 automatically sends the operation instruction, so that the large-screen conference terminal 102 receives the operation control instruction sent by the master terminal 104 and executes the operation control instruction. Compared with the previous situation of using a remote controller to need to operate multiple times to meet the demand, the operation complexity is high, and the operation convenience is low, the embodiment not only has simple operation and improves the convenience, but also saves the time of the user, improves the efficiency of the conference, and brings good operation experience to the user.

[0063] In some embodiments, when receiving the operation control instruction sent by the master terminal 104, executing the operation control instruction includes the following steps:

[0064] In the case where the operation control instruction is a click instruction, the coordinate information contained in the click instruction is converted to the corresponding position on the screen of the large-screen conference terminal 102 and displayed;

[0065] A corresponding click event is generated by simulating the click instruction, and the click event is executed according to the click event. That is, the operation on the master terminal 104 can be directly reflected on the large-screen video conference device, and good operation experience is brought to the user.

[0066] Reference Figure 3 In order to facilitate communication with the master terminal 104, in some embodiments, before receiving the broadcast message sent by the master terminal 104, the method includes the following steps:

[0067] Registering a listening port;

[0068] When the listening port listens to a UDP port, a random check code is generated. In actual use, the listening port can be a UDP port or other, which is not limited here;

[0069] Further, in some embodiments, before receiving the check code sent by the master terminal 104, the method further includes:

[0070] The random check code is input into the host terminal 104, so that the host terminal 104 sends the random check code to the large-screen conference terminal 102 according to the first IP address and the first port number. That is, only when the input random check code is consistent with the random check code generated by the large-screen conference terminal before, the large-screen conference terminal 102 and the host terminal 104 can establish a communication connection, so that the security is improved.

[0071] Because the maximum number of 4-digit verification code is 9999, that is, 10000 values, the speed of cracking by using a brute-force software is very fast. In addition, if a 5-digit number is used, it is not easy to remember. In order to facilitate people to remember, in some embodiments, the number of bits of the random check code is 6. Of course, in some other embodiments, in order to improve the security, the number of bits of the random check code can also be set to be higher, which is not limited here.

[0072] In some embodiments, the video image is a YUV image. Of course, in other embodiments, other formats of images with smaller storage space or easier transmission can also be selected, which is not limited here.

[0073] The embodiment also provides another method for controlling a large-screen video conference system, applied to a system including a large-screen conference terminal 102 and a host terminal 104, and the method includes the following steps:

[0074] When the large-screen conference terminal 102 receives the broadcast message sent by the host terminal 104, the first IP address and the first port number are returned, wherein the first IP address and the first port number are the IP address and the port number of the large-screen conference terminal 102, and the second IP address and the second port number are carried in the broadcast message, and the second IP address and the second port number are the IP address and the port number of the host terminal 104; when the check code sent by the host terminal 104 is received, the check code is checked;

[0075] In the case that the check is successful and the large-screen conference terminal 102 and the host terminal 104 are connected, the large-screen conference terminal 102 acquires a video image and sends the video image to the host terminal 104, wherein the video image is a video image compressed by an H264 algorithm;

[0076] The operation control instruction sent by the host terminal 104;

[0077] When the large-screen conference terminal 102 receives the operation control instruction sent by the master terminal 104, the operation control instruction is executed. In this embodiment, without external equipment, when a corresponding operation is performed on the master terminal 104 (also referred to as a control terminal) in the range of the local area network, the master terminal 104 sends a corresponding operation instruction to the large-screen conference terminal 102. When the operation control instruction sent by the master terminal 104 is received, the operation control instruction is executed. This process does not require external equipment or connection to the Internet. In a pure intranet (i.e., local area network) environment, by operating a master terminal 104, the large-screen conference terminal 102 can directly execute the operation control instruction. Thus, the operation on the master terminal 104 is directly reflected on the large-screen conference terminal 102 (i.e., the large-screen video conference equipment). In this way, the complexity of the operation is reduced, the convenience of the operation is improved, and the problem of high operation complexity and low operation convenience in the related art, in which the large-screen conference terminal 102 can only be operated by external equipment such as a mouse, a keyboard, or a remote controller, is solved. On the other hand, since the operation is convenient, a large amount of time is saved, the efficiency of the conference is improved, and thus a good operation experience is provided for the user.

[0078] It should be noted that the steps shown in the above flow or the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0079] The embodiment also provides a large-screen video conference device, which is used to implement the above-described embodiments and preferred embodiments, and will not be described again. As used below, the terms "module", "unit", "sub-unit", and the like can be a combination of software and / or hardware that implements a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware or a combination of software and hardware is also possible and contemplated.

[0080] Figure 4 is a structural block diagram of a large-screen video conference device according to the embodiment of the application, as shown in Figure 4 The device includes:

[0081] The return unit 41 is configured to return a first IP address and a first port number when receiving a broadcast message sent by the master terminal 104, where the first IP address and the first port number are the IP address and the port number of the large-screen conference terminal 102, and the broadcast message carries a second IP address and a second port number, and the second IP address and the second port number are the IP address and the port number of the master terminal 104.

[0082] The checking unit 42 is configured to check the check code when the check code sent by the master terminal 104 is received.

[0083] The acquiring unit 43 is configured to acquire the video image when the checking succeeds and the connection with the master terminal 104 is established.

[0084] The sending unit 44 is configured to send the video image to the master terminal 104, wherein the video image is the video image compressed by the H264 algorithm.

[0085] The executing unit 45 is configured to execute the operation control instruction when the operation control instruction sent by the master terminal 104 is received. In this embodiment, the operation of the large-screen conference terminal 102 can be performed without an external device. When the operation on the master terminal 104 (also referred to as a control terminal) is performed in the range of the local area network, the master terminal 104 sends the corresponding operation instruction to the large-screen conference terminal 102. When the operation control instruction sent by the master terminal 104 is received, the operation control instruction is executed. This process does not require an external device or an Internet connection. In a pure intranet (i.e., a local area network) environment, the large-screen conference terminal 102 can be directly controlled to execute the operation control instruction by operating the master terminal 104. Thus, the operation on the master terminal 104 is directly reflected on the large-screen conference terminal 102 (i.e., a large-screen video conference device). In this way, the complexity of the operation is reduced, the convenience of the operation is improved, and the problem of high operation complexity and low operation convenience in the related art, which can be solved only by using an external device such as a mouse, a keyboard, or a remote controller, is solved. On the other hand, since the operation is convenient, a large amount of time is saved, the efficiency of the conference is improved, and thus a good operation experience is provided for the user.

[0086] This embodiment further provides another large-screen video conference system, which is applied to a system including the large-screen conference terminal 102 and the master terminal 104. The system includes:

[0087] The master terminal 104 is configured to send the broadcast message.

[0088] The large-screen conference terminal 102 is configured to return the first IP address and the first port number when the broadcast message is received, wherein the first IP address and the first port number are the IP address and the port number of the large-screen conference terminal 102, and the second IP address and the second port number are carried in the broadcast message, wherein the second IP address and the second port number are the IP address and the port number of the master terminal 104.

[0089] The master terminal 104 is further configured to receive the input check code.

[0090] The large-screen conference terminal 102 is further configured to, when the check code is received, check the check code; in a case where the check is successful and a connection with the master terminal 104 is established, acquire a video image and send the video image to the master terminal 104, wherein the video image is a video image compressed by the H264 algorithm.

[0091] The master terminal 104 is further configured to receive the video image; decompress the video image and display the decompressed video image; and when an operation instruction is received, send the operation instruction to the large-screen conference terminal 102, wherein the operation instruction at least includes a click instruction.

[0092] The large-screen conference terminal 102 is further configured to, when the operation control instruction is received, execute the operation control instruction. In this embodiment, without an external device, when a corresponding operation is performed on the master terminal 104 (also referred to as a control terminal) within the scope of a local area network, the master terminal 104 sends a corresponding operation instruction to the large-screen conference terminal 102. When the operation control instruction sent by the master terminal 104 is received, the operation control instruction is executed. This process does not require an external device or an Internet connection. In a pure intranet (i.e., a local area network) environment, by operating a master terminal 104, the large-screen conference terminal 102 can be directly controlled to execute the operation control instruction. Thus, the operation performed on the master terminal 104 is directly reflected on the large-screen conference terminal 102 (i.e., a large-screen video conference device). In this way, the complexity of the operation is reduced, the convenience of the operation is improved, and the problem of high operation complexity and low operation convenience in related technologies, in which a large-screen conference terminal 102 can only be operated by an external device such as a mouse, a keyboard, or a remote controller, is solved. On the other hand, because the operation is convenient, a large amount of time is saved, the efficiency of a conference is improved, and thus a user has a good operation experience.
