For example, one image data to be transmitted may be divided into 4 different-sized portions (34, 35, 36, 37) shown in fig. 3, which are allocated to the channels 11,22, 33, and 44, respectively. These parts will then be sent to the communication terminal 2 via the respective channels, and the data of the respective parts will be recombined by the communication terminal 2 by means of the markers as required to form complete data, e.g. for a segmented image as shown in fig. 3, the communication terminal will stitch the received data to form the original image frame, again in accordance with 34, 35, 36, 37.
After step S6, steps S1-S5 are repeatedly performed. According to some embodiments of the invention, only steps S5 and S6 may be performed for a period of time after step S6.

According to some embodiments of the present invention, the communication terminal 2 compares the latest timestamp with the current time to obtain the transmission time, and then calculates the transmission time and the data size to obtain the transmission bandwidth of the current data. For example, the time consumption for transmitting the data with the size of 1M is continuously counted, so that the relatively accurate real-time network transmission bandwidth of the current network transmission can be calculated. Or comparing some two timestamps to obtain the transmission time, and then calculating the data size between the transmission time and the two timestamps to obtain the average transmission bandwidth in the time.
At S25, the communication terminal 2 transmits the transmission bandwidth of each channel back to the mobile commander terminal of the communication terminal 1.
At S26, the mobile commander terminal of the communication terminal 1 receives the transmission bandwidth of each channel, and calculates the data allocation amount of each channel based on the transmission bandwidth of each channel.
According to some embodiments of the present invention, if no feedback from the communication terminal 2 is received on a certain channel, or the feedback exceeds a certain time, the channel is regarded as unavailable for transmission, or the real-time transmission bandwidth approaches to 0 indefinitely, and then the data allocation amount of the channel may be calculated as 0.
