Abstract

The invention relates to the technical field of data transmission, and particularly discloses a multi-channel data transmission adjusting method and adjusting device. The method comprises the following steps: acquiring a current link state of each transmission channel; re-determining the frame rate and the synchronization strategy of each transmission channel according to the current link state of each transmission channel; controlling each transmission channel to adjust the respective frame rate based on the re-determined frame rate, and completing multi-channel link synchronization with the video source end based on the re-determined synchronization strategy. Therefore, the frame rate and the synchronization strategy of each transmission channel can be adjusted in real time according to the current link state of each transmission channel, that is, the effective load capacity of the transmission channel can be adaptively adjusted according to different states of the transmission channel, the situation of data congestion or insufficient data is avoided, the data transmission rate and the resource utilization rate are improved, and meanwhile, data transmission among the transmission channels can be synchronized, so the display effects of the video devices corresponding to the transmission channels are kept consistent.
