[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0026] At present, in order to provide a more realistic visual experience, telepresence systems generally use multiple screens to create a three-dimensional sense. A single device performs multi-channel ultra-high-definition video encoding and decoding, which places high demands on hardware resources; and using multiple split devices to transmit and encode multiple images separately makes it difficult to ensure the synchronization of multiple screens when encountering a relatively complex network environment.

[0027] Based on this, the embodiment of the present invention provides a data transmission method, device and electronic device for a multi-screen telepresence terminal. The technology calculates the transmission delay of the slave screen device through the local area network status data, thereby recalibrating the media data, and achieves the effect of synchronization of multiple screens by displaying the recalibrated media data from the slave screen device. To facilitate understanding of the embodiment of the present invention, a data transmission method for a multi-screen telepresence terminal disclosed in the embodiment of the present invention is first introduced in detail.

[0028] Example 1

[0029] In this embodiment, Figure 1 A schematic flow chart of a data transmission method for a multi-screen telepresence terminal provided by an embodiment of the present invention.

[0030] In actual operation, the multi-screen telepresence terminal includes a master screen device and at least one slave screen device.

[0031] Here, the structure of the multi-screen telepresence terminal has low requirements for the device hardware, as long as it can meet the requirements of encoding and sending one video screen, and receiving, decoding and displaying one video screen. The main screen device only needs to increase the ability to aggregate and distribute all video data through the network in addition to the basic parameter requirements of the slave screen device. In addition, if the data forwarding capability of the main screen device is sufficient, more telepresence screens can be expanded by expanding the slave screen devices.

[0032] Furthermore, by aggregating all video data to the master screen device for unified transmission, even in a relatively complex external network environment, the consistency of multi-screen video data transmission to the external network can be guaranteed. Furthermore, the master screen device and the slave screen device are connected to the same switch via a network cable, which can ensure relatively reliable local area network transmission.

[0033] Depend on Figure 1 As can be seen, the method includes:

[0034] Step S101: if a decoding and displaying instruction is received, media data is acquired through the above-mentioned main screen device, and local area network status data is acquired.

[0035] Step S102: calibrate the media data according to the time of the master screen device to obtain calibrated media data, and calculate the transmission delay of the slave screen device according to the local area network status data.

[0036] Here, the transmission delay of the media data of each slave screen device through the local area network is counted on the master screen device, thereby calculating the transmission delay of the media data of the slave screen device.

[0037] Step S103: based on the transmission delay, recalibrate the calibrated media data to obtain recalibrated media data.

[0038] In actual operation, based on the above-mentioned transmission delay, the above-mentioned calibrated media data is recalibrated to obtain the recalibrated media data, including: loading the above-mentioned transmission delay before the decoding and display link of the above-mentioned calibrated media data through the above-mentioned main screen device to obtain the recalibrated media data.

[0039] Step S104: transmitting the recalibrated media data to the slave screen device, so that the recalibrated media data is displayed by the slave screen device.

[0040] An embodiment of the present invention provides a data transmission method for a multi-screen telepresence terminal, wherein the multi-screen telepresence terminal includes a main screen device and at least one slave screen device, and the method includes: if a decoding display instruction is received, media data is obtained through the main screen device, and local area network status data is obtained; the media data is calibrated according to the time of the main screen device to obtain calibrated media data, and the transmission delay of the slave screen device is calculated according to the local area network status data; based on the transmission delay, the calibrated media data is recalibrated to obtain recalibrated media data; the recalibrated media data is transmitted to the slave screen device, so that the recalibrated media data is displayed by the slave screen device. This technology calculates the transmission delay of the slave screen device through the local area network status data, thereby recalibrating the media data, and displays the recalibrated media data by the slave screen device, so as to achieve the effect of synchronization of multiple screen images.

[0041] Example 2

[0042] Based on the above embodiments, Figure 2 A flowchart of another data transmission method for a multi-screen telepresence terminal provided by an embodiment of the present invention.

[0043] Here, the multi-screen telepresence terminal includes a master screen device and at least one slave screen device.

[0044] Depend on Figure 2 As can be seen, the method includes:

[0045] Step S201: if a decoding and displaying instruction is received, media data is acquired through the main screen device, and local area network status data is acquired.

[0046] Step S202: calibrate the media data according to the time of the master screen device to obtain calibrated media data, and calculate the transmission delay of the slave screen device according to the local area network status data.

[0047] Step S203: Filter the target transmission delay with the largest value among the transmission delays of the slave screen devices.

[0048] Step S204: based on the target transmission delay, recalibrate the calibrated media data to obtain recalibrated media data.

[0049] In actual operation, based on the above-mentioned transmission delay, the above-mentioned calibrated media data is recalibrated to obtain the recalibrated media data, including: based on the above-mentioned target transmission delay, each of the above-mentioned calibrated media data corresponding to the above-mentioned slave screen device is recalibrated respectively to obtain the recalibrated media data.

[0050] Step S205: transmitting the recalibrated media data to the slave screen device, so that the recalibrated media data is displayed by the slave screen device.

[0051] In one embodiment, after the step of displaying the recalibrated media data on the screen device, the method further includes the following steps A1 to A3:

[0052] Step A1: determining, by the slave screen device, based on the recalibrated media data, whether the media data has the transmission delay.

[0053] Step A2: If the above transmission delay exists, the above transmission delay is loaded before the forwarding link of the above main screen device to obtain the re-calibrated media data.

[0054] Step A3: forwarding the recalibrated media data to the slave screen device via the master screen device, so that the slave screen device displays the recalibrated media data.

[0055] Furthermore, the main screen device needs to change the display of the main screen device itself according to the delay, and then add the maximum delay to the display screen of the main screen device to make the main screen device display slower; the slave screen device also needs to add the above transmission delay before forwarding the above media data, that is, the non-maximum delay.

[0056] Furthermore, the maximum delay is superimposed on the media data of the host device, and the display screen of the main screen device is adjusted, and the slave screen still displays the original screen. Furthermore, the slave screen device displays the adjusted media data at the non-maximum delay, so that the slave screen device will also display a little slower.

[0057] The embodiment of the present invention provides a data transmission method for a multi-screen telepresence terminal, wherein the multi-screen telepresence terminal includes a main screen device and at least one slave screen device, and the method includes: if a decoding display instruction is received, media data is obtained through the main screen device, and local area network status data is obtained; the media data is calibrated according to the time of the main screen device to obtain calibrated media data, and the transmission delay of the slave screen device is calculated according to the local area network status data; the target transmission delay with the largest value among the transmission delays of the slave screen devices is screened; based on the target transmission delay, the calibrated media data is recalibrated to obtain the recalibrated media data; the recalibrated media data is transmitted to the slave screen device, so that the recalibrated media data is displayed by the slave screen device. The technology calculates the transmission delay of the slave screen device through the local area network status data, and screens out the target transmission delay with the largest value among the transmission delays, thereby recalibrating the media data based on the target transmission delay, and the recalibrated media data is displayed by the slave screen device, so as to further enhance the synchronization effect of the multi-screen images.
