A miracast background resident channel following method

Abstract

The present invention relates to the field of screen projection technology. In order to make reasonable use of resources, avoid channel resource waste caused by excessive channel switching, and improve the work efficiency between STA and P2P, a method for channel follow-up in the background of Miracast is provided, including: Miracast Monitoring phase: the monitoring channel of the TV side follows the working channel of the STA mode of the Wi-Fi module of the TV side; working phase of screen projection: the working channel of Miracast follows the working channel of the STA mode of the Wi-Fi module of the TV side. Using the above method can reduce the search time for screen projection matching, so as to realize that without changing the inherent Wi-Fi resources of smart TVs, it is possible to solve the disadvantages of channel resource waste of smart TVs under the Miracast background resident function, and improve Improve the work efficiency between STA and P2P.

Description

A method of channel following in the background of Miracast technical field [0001] The present invention relates to the technical field of screen projection, in particular to a method for channel following under a Miracast background resident. Background technique [0002] Miracast screencasting (P2P screencasting) is a wireless screencasting between different electronic devices (such as TVs, smart phones, and computers). A protocol for the Called the transmission end GO - Group Owner, it is a virtual character, which will actually correspond to a P2P server, which is similar to AP in Infrastructure BSS, optional Miracast working channel and other information; the other part is called receiving End GC - P2P Client, a virtual role opposite to GO, it is similar to STA in Infrastructure BSS. [0003] For TV equipment, the most application scenario is the screen projection interaction with a mobile phone or a computer. its projection side There are roughly three types o...

Problems solved by technology

However, due to the limited inherent resources of the single Wi-Fi module equipped on the smart TV, and the Miracast background resident function performs frequent switching of P2P monitoring channels in the STA mode of the Wi-Fi module on the TV side, and the Miracast on the TV side is working. -The network connection coexistence problem under the STA channel of the Fi module makes the work efficiency between STA and P2P low
