Before the connection, the first wireless transmission module 112 is not connected to any of the secondary transceivers, that is, the second electronic device 120 , the third electronic device 130 and the fourth electronic device 140 . When connecting, the first wireless transmission module 112 will continuously broadcast a broadcast signal S _b to all nearby second electronic devices 120 , third electronic devices 130 and fourth electronic devices 140 . The broadcast signal S _b includes the control signal _Sc , the pairing information _Im and the audio-visual information I _s .

When the first electronic device 110 determines that there is no matching quota q, the first electronic device 110 uses the first wireless transmission module 112 to continuously broadcast the broadcast signal S _b to inform nearby devices that pairing is currently unavailable.

When the first electronic device 110 executes the pairing procedure, the first electronic device 110 sends the pairing signal S _m through the first wireless transmission module 112 , and the second electronic device 120 receives the pairing signal S _m through the second wireless transmission module 122 . The pairing signal S _m includes the device independent identification code L _idm , the tag T _m and the pairing control signal S _cm . If the first electronic device 110 is currently only paired with the second electronic device 120, when the first electronic device 110 receives the pairing application A _m1 from the third electronic device 130, the first electronic device 110 uses the first wireless transmission module 112 The pairing signal S _m1 is sent to the third electronic device 130 , and the third electronic device 130 receives the pairing signal S _m1 via the third wireless transmission module 132 .

The first electronic device 110 determines whether it already has the matching quota q (S23). When the first electronic device 110 has the pairing quota q, the first electronic device 110 executes a pairing procedure (S24). When the first electronic device 110 and the second electronic device 120 are connected, the first electronic device 110 transmits the audio and video information _Is to the second wireless transmission module 122 through the first wireless transmission module 112, and communicates with the second electronic device. 120 for audio and video transmission.

In this preferred embodiment, when the first electronic device 110 and the second electronic device 120 are connected, the second electronic device 120 determines whether the first electronic device 110 has been paired and connected before. (S30). A connection code L _id is used as the first electronic device 110 that has been previously paired (S32). If the connection code L _id is found, it is determined whether the pairing tag of the second electronic device 120 still appears in the pairing tag signal of the broadcast signal (S34). If the pairing tag T _b of the second electronic device 120 still appears in the pairing tag signal _St of the broadcast signal S _b , the second electronic device 120 is connected to the first electronic device 110 (S36). If the pairing tag _St of the second electronic _device 120 does not appear in the pairing tag signal St of the broadcast signal S _b , it is determined whether the first electronic device 110 still has a pairing quota (S33).

Broadcasting (S31). If the second electronic device 120 searches for the first electronic device 110 that is broadcasting, it determines whether the first electronic device 110 still has a matching quota (S33). If it is determined that the first electronic device 110 does not have a matching quota, the second electronic device 120 searches whether the first electronic device 110 is broadcasting. The second electronic device 120 sends a pairing application _Am to the first electronic device 110 to apply for joining the paired connection group (S35). If the first electronic device 110 does not agree to the pairing application _Am , it is determined whether the first electronic device 110 still has a pairing quota. If the first electronic device 110 agrees to the pairing application _Am , the first electronic device 110 executes the pairing procedure and obtains a tag T _m of the first electronic device 110 (S37).
