Abstract

The invention relates to a data transmission method, a system and device. The data transmission method comprises the following steps: detecting whether a confirmation data packet is existent in a confirmation information sending queue of a receiving end in the process of feeding back the confirmation information to a sending end by the receiving end, wherein the confirmation data packet is the confirmation information generated after the receiving end receives the play data; if the confirmation data packet is inexistent in the confirmation information sending queue, generating a blank data packet, and sending the blank data packet to the confirmation information sending queue; and sending the queue content in the confirmation information sending queue to the sending end. By use of the data transmission method, system and device provided by the invention, the transmission efficiency of each of the corresponding play data and the confirmation data packet can be improved, thereby improving the effect of displaying or playing the corresponding play data at the receiving end.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular to a data transmission method, system and device. Background technique [0002] Multiple smart display devices can be connected to each other through screen transfer devices to realize the real-time transmission of playback data (such as audio data, video data and / or image data, etc.) between each smart display device, so that users can use one of the smart display devices. The display device can watch the content currently displayed by other smart display devices, so that the user can more conveniently obtain the content displayed by the above-mentioned smart display device. [0003] In the process that the smart display device receives the playback data sent by other display devices through the screen transfer device for display, the smart display device that sends the playback data can be called the sender, and the smart display device that receives the playback data sent by o...
