Abstract
(EN) Embodiments of the present invention are applicable in the technical field of communications. Disclosed are a method, system, and related device for data transmission. In the method for data transmission of the embodiments of the present invention, a host acquires parameter information of a wireless communication channel between a wireless array microphone and the host, that is, a signal-to-noise ratio and/or bandwidth, if the acquired parameter information satisfies a first preset criterion, then either a sampling frequency of the wireless array microphone is reduced or the number of data transmission paths between the wireless array microphone and the host is reduced, thus allowing for a reduction in the bandwidth taken up by the wireless array microphone when transmitting data. As such, the host is allowed to dynamically adjust a parameter of the wireless array microphone for data transmission on the basis of actual conditions of communication between the wireless array microphone and the host, thus satisfying as much as possible requirements of the wireless array microphone in communication with the host.
(FR) Les modes de réalisation de la présente invention relèvent du domaine technique des communications. L'invention concerne un procédé, un système et un dispositif de transmission de données. Dans le procédé de transmission de données selon les modes de réalisation de la présente invention, un hôte acquiert des informations de paramètres d'un canal de communication sans fil entre un microphone de réseau sans fil et un hôte, c'est-à-dire un rapport signal-bruit et/ou la largeur de bande, si les informations de paramètres acquises répondent à un premier critère prédéfini, après quoi une fréquence d'échantillonnage du microphone de réseau sans fil est réduite ou le nombre de trajets de transmission de données entre le microphone de réseau sans fil et l'hôte est réduit, permettant ainsi une réduction de la largeur de bande occupée par le microphone de réseau sans fil lors de la transmission de données. En tant que tel, l'hôte est autorisé à ajuster dynamiquement un paramètre du microphone de réseau sans fil pour la transmission de données sur la base de conditions réelles de communication entre le microphone de réseau sans fil et l'hôte, ce qui permet de satisfaire autant que possible aux exigences du microphone de réseau sans fil en communication avec l'hôte.
(ZH) 本发明实施例公开了数据传输方法、系统及相关设备,应用于通信技术领域。在本实施例的数据传输方法中,主机会获取无线阵列麦克风与主机之间的无线通信信道的参数信息,即信噪比和/或带宽,如果获取的参数信息满足第一预置条件,则降低无线阵列麦克风的采样频率或减少无线阵列麦克风与主机之间的数据传输路径数,使得无线阵列麦克风传输数据时所占用的带宽减少。这样,主机可以根据无线阵列麦克风与主机之间通信的实际情况,动态地调整无线阵列麦克风传输数据的参数,尽量满足了与主机通信的无线阵列麦克风的需求。
