A method for identifying interconnected devices, master smart device and slave smart device

Abstract

The embodiment of the invention provides an interconnection device identification method, a master intelligent device and a slave intelligent device. The method comprises the following steps: detecting whether a connection signal exists, wherein the connection signal is generated when the master intelligent device and the slave intelligent device are connected via a video transmission data line; if detecting the connection signal, transmitting a video signal to the slave intelligent device via the video transmission data line, and sending a notification instruction to the slave intelligent device in a wireless communication mode, so as to trigger the slave intelligent device to transmit operation control data to the master intelligent device in the wireless communication mode, wherein the notification instruction is used for indicating that the slave intelligent device and the master intelligent device have been successfully connected to the video transmission data line. In the interconnection device identification method provided by the embodiment of the invention, the slave intelligent device can automatically identify the master intelligent device connected with the video transmission data line, thereby providing possibility for the slave intelligent device to conveniently determines the master intelligent device that requires reverse control.

Description

technical field [0001] The invention relates to the technical field of device interconnection, in particular to a method for identifying interconnected devices, a master smart device and a slave smart device. Background technique [0002] With the popularity of smart devices, there are more and more cases of interconnection and intercommunication between smart devices, and an audio-visual projection method based on interconnected devices has emerged; the audio-visual projection method based on interconnected devices mainly refers to , when the smart devices are connected by an audio-visual transmission data cable that can transmit audio-visual signals, one of the smart devices can use the audio-visual transmission data cable to transmit audio-visual signals to another smart device, so that the other device can be used as an audio-visual projection On the other device, audio and video playback can be realized, and audio and video transmission data lines such as HDMI (High Def...

Problems solved by technology

[0004] The inventors of the present invention found that the method of reversely controlling the master smart device by operating the slave smart device needs to be established on the basis that the master and slave smart devices have been connected through audio-visual transmission data lines. However, protocols based on audio-visual transmission data lines such as HDMI , after the slave smart device is connected to the master smart device through the audio and video transmission data cable, the slave smart device cannot automatically identify the connected master smart device, which brings certain difficulties for the slave smart device to determine the master smart device that needs reverse control trouble;
