Abstract

The invention discloses a data transmission system, method and device. The data transmission system is composed of a sending terminal and a receiving terminal. The sending terminal sends data sources through at least two communication interfaces; and the receiving terminal connected with the sending terminal is used for receiving the data sources sent by the sending terminal through the at least two communication interfaces, wherein the at least two of the communication interfaces in the sending terminal are connected with at least two communication interfaces in the receiving terminal correspondingly. Therefore, a technical problem that the video transmission efficiency is low because anti-interference video data transmission can not be carried out on the condition of wifi in the prior art is solved.

Description

technical field [0001] The present invention relates to the application field of communication technology, in particular, to a data transmission system, method and device. Background technique [0002] With the development of office multimedia technology and the maturity of wifi technology, more and more office electronic devices have wifi function. [0003] Now more and more projector conference room terminal display devices begin to use Wi-Fi signals to transmit video data. Wi-Fi transmission does not require wiring, which is easy to move and use. However, one disadvantage of this transmission method is that it is susceptible to interference. When the interference reaches a certain level, data transmission becomes unreliable and the transmission delay increases. This unreliability has little impact on non-real-time application scenarios, but it is unacceptable for application scenarios with strong real-time characteristics such as video transmission. [0004] The curren...
