Abstract

The present invention relates to a data transmission method, system and device. The data transmission method comprises the following steps: in the process of a receiving end feeding back confirmation information to a sending end, detecting whether a confirmation data packet exists in a confirmation information sending queue of the receiving end, the confirmation data packet being confirmation information generated after the receiving end receives playback data; if there is no confirmation data packet 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 queue content in the confirmation information sending queue to the sending end. The data transmission method, system and device provided by the present invention may increase the transmission efficiency of corresponding playback data and a confirmation data packet, thereby improving the effect of displaying or playing back the corresponding playback 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 transmission devices to realize real-time transmission of play data (such as audio data, video data and / or image data, etc.) between smart display devices, so that users can pass one of the smart The display device can watch the content currently displayed by other intelligent display devices, so that the user can more conveniently obtain the content displayed by the above-mentioned intelligent display device. [0003] In the process of a smart display device receiving 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 other display...
