蓝牙芯片与VoLTE技术在广播连线节目录制中的应用实践

Application of Bluetooth Chip and VoLTE Technology in Recording Room

随着无线高清语音VoLTE技术的发展,广播电话连线节目的录制具备了采集高品质声音信号的基础。本文介绍的基本方法是,利用LTE网络平台,通过公共无线网络4G高清语音平台的通信链路,将具有VoLTE功能的手机作为传输主体,把电话来电的语音信号通过无线蓝牙传输方式耦合到广播连线节目的录制调音台上,完成来电语音信号和主持人语音信号的拾取和录制。这一方法下完成的音频录制质量远远高于传统的电话耦合器线路方式,在广播连线节目录制中具有广泛的应用前景。

With the development of wireless high-definition voice volte technology, it is now possible to make full use of the LTE network platform. Through the communication link of the public wireless network 4G high-definition voice platform, the mobile phone with volte function is used as the transmission main body, and the voice signal of the incoming call is coupled to the recording console through wireless blue tooth transmission, so as to realize the recording of the telephone connection of external guests in the recording room, and the audio quality is much better than the traditional telephone coupler line.
