The Radio Link of the system of Fig. 1 is configured such that realize MTN, wherein each audio transmission unit can be via wireless Its audio signal is sent each audio receiver unit by link, to realize multi-multipoint link.Although can be used Proprietary network agreement realizes such multi-multipoint link (for example, with reference to US 9,247,355B2 as described above), but It is that the standard wireless communication agreement of such as BLE usually only provides point-to-point link.Even if to this standard agreement be extended with Allow audio data broadcasting, such as US 8, described in 849,202B2, this point-to-multipoint link will not generate required multiple spot To multipoint link.
As shown in Figure 1, from point-to-multipoint to multi-multipoint this extension, (or point-to-point link is to multi-multipoint chain The extension on road) it can realize as follows: one in audio transmission unit, such as the first audio transmission unit 10, it is received with audio At least one of device unit 20,22,24 establishes the first Radio Link 32 (in general, as shown in Figure 1, the first link 32 is embodied as Audio broadcast link；But it is also possible to point-to-point link only with an audio receiver unit in principle).Then, First link 32 can by the first audio transmission unit 10 using come by audio data be sent to audio receiver unit 20,22, 24.Therefore, the first audio transmission unit 10 know via the first link 32 carry out audio data transmission needed for all information (under Wen Zhong, this information will be referred to as " link parameter collection ").
In addition, the first audio transmission unit 10 is respectively via the second Radio Link 34A and third Radio Link 34B and other Audio transmission unit is communicated with the second audio transmission unit 12 and third audio transmission unit 14, wherein second and The agreement different from the agreement of the first link 32 can be used in three link 34A, 34B, but they also can be used and the first chain The identical agreement in road 32.In general, second and third link 34A, 34B be configured as realizing client/server, wherein first send it is single Member 10 is used as main equipment, and second and third audio transmission unit 12,14 be used as from equipment.
First audio transmission unit 10 can be used second and third link 34A, 34B be used for via the first link 32 send Link parameter collection needed for audio data is transmitted to second and third audio transmission unit 12,14, and then second and third audio Transmission unit 12,14 can simulate the first audio transmission unit 10, with for by audio data from second and third transmission unit 12,14 it is sent to audio receiver unit 20,22,24, is received to be respectively created from the second audio transmission unit 12 to audio First link 32A of the simulation of device unit 20,22,24 and from third audio transmission unit 14 to audio receiver unit 20,22, First link 32B of 24 simulation.
It is appreciated that audio data can be made of compressed audio signal and audio related control data, the audio phase Close control data it is for example related to the gain of signal to be applied to, at audio transmission unit measurement ambient noise it is related or It is related to the state of voice activity detected by VAD 124.
Second and third link 34A, 34B can be additionally configured to realize One-to-All Broadcast framework (for example, logical using BLE Accuse), wherein the first transmission unit 10 broadcasts " link parameter to the second audio transmission unit 12 and third audio transmission unit 14 Collection ".
Second and third link 34A, 34B can also be made by the second audio transmission unit 12 and third audio transmission unit 14 With sending the first audio transmission unit 10 for information relevant to the first link 32.For example, such information can be point The value of group counter, or the list of the good channels used in adaptive frequency hopping scheme.It should be appreciated that at " link parameter collection " Initial distribution after, primary role can be exchanged between transmitter.
By enable second and third audio transmission unit 12,14 simulate the first audio transmission unit 10, when from audio When the visual angle of acceptor unit 20,22,24 is seen, the first, second, and third audio transmission unit 10,12,14 is used as single audio Transmission unit, thus will actually be established between the first audio transmission unit 10 and audio receiver unit 20,22,24 first Link 32 extends to second and third transmission unit 12,14；To realize multi-multipoint connection.
It preferably, is standard BLE agreement by the agreement that the first link 32 uses.The use of this standard agreement usually requires Access address, timing synchronisation information and hopping sequence information are known, so as to imitate the first audio transmission unit 10 to use First link 32.In general, access address is selected by the first audio transmission unit 10 when establishing the first link 32.Therefore, at this In the case of kind, by the first audio transmission 10 be transmitted to second and the link parameter collection of third audio transmission unit 12,14 at least wrap Include these parameters, i.e. access address, timing synchronisation information and hopping sequence information.In addition, link parameter collection may include decryption Key may be required for encryption data to be decrypted.
Second and third link 34A, 34B can be used standard agreement, such as BLE agreement or it can be used it is proprietary Agreement.
The term " imitation " also used in cryptography or " simulation " it is generally understood that for " pretending to be (another person) " or " assuming that or play the part of ... role " meaning.
