The invention discloses a WiFi‑Display performance optimization system, which relates to the technical field of audio and video transmission, specifically a start module, an auto-negotiation GO module and a GO Intent adjustment module. The output end of the start module is electrically connected to a WIFI P2P transmission module , and the output end of the WIFI P2P transmission module is electrically connected to the PP connection module, the output end of the PP connection module is electrically connected to the device GO first selection module, the input end of the automatic negotiation GO module and the GO Intent adjustment module Both are electrically connected to the output end of the first GO selection module of the device, and a GO Intent adjustment module is arranged on the right side of the auto-negotiation GO module, and the output end of the auto-negotiation GO module is electrically connected to the second selection module of the device GO. The WiFi‑Display performance optimization system can scan all available channels under the action of the AP connection module, and set up the BSS corresponding to the GROUP on channel C best , and then connect AP and GO smoothly, and the channel connecting AP and GO is the optimal channel.
Description
technical field [0001] The invention relates to the technical field of audio and video transmission, in particular to a WiFi-Display performance optimization system. Background technique [0002] WFD is a multimedia communication framework based on WIFI P2P network. This specification describes how two devices supporting WiFi-Display can discover each other, pair up, establish P2P connection, negotiate audio and video parameters, transmit audio and video data, and end audio and video transmission. The process of disconnecting the P2P connection. In this process, the end that provides audio and video is called DisplaySource, referred to as the Source end, and the end that receives and displays audio and video is called DisplaySink, referred to as the Sink end. WIFI P2P is a network that supports WIFI P2P The communication mode that directly establishes a communication link between the devices without the intervention of an AP. When two devices that support WIFI P2P establish ...
