The embodiment of the invention provides a video data transmission method and video data transmission equipment. The video data transmission method specifically comprises the following steps of: determining the communication quality of a data card according feedback information of the data card during data transmission; and sending basic layer video data by using the data card with the highest communication quality, wherein when the bandwidth of a communication network has relatively high fluctuation, the transmission quality of the basic layer video data can be guaranteed, and the communication quality of the data card can be obtained during data transmission, so that unnecessary extra resources are not required to monitor the network quality; furthermore, when the network quality is changed, the video data is not required to be re-encoded, and the instantaneity of video data transmission is guaranteed.
