Abstract

The invention discloses a voice data processing method, device and system and a controlled device. The voice data processing method is used for the controlled device. The controlled device is connected with a main control device; the time of the controlled device is synchronized with that of the main control device through an IEEE1588 precision time protocol; the main media clock signal of the main control device and the IEEE1588 reference clock signal of the main control device adopt the same frequency source; the voice data processing method comprises following steps: converting a first media voice digital signal into a first network voice digital signal synchronous with the main media clock signal; the first media voice digital signal is the voice digital signal synchronous with the media clock signal of the controlled device; and the first network voice digital signal is sent to the main control device. In application of the technical solution of the invention to a video session system, the demand for the processing capacity of a video session host can be reduced; therefore, more microphones can be cascaded with the video session host; and the scalability of the voice data processing system can be improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to an audio data processing method, an audio data processing device, a controlled device and an audio data processing system. Background technique [0002] Currently, common audio communication systems include a VoIP (Voice Over Internet Protocol, Internet Protocol) telephone and an audio subsystem in a video conference. Such as figure 1 As shown, the video conferencing system includes: a video conferencing host, multiple displays, multiple cameras, loudspeakers, PC (Personal Computer, personal computer) and a microphone, wherein the video conferencing host is connected to the IP network through cables or wireless signals; The display is used to display local on-site video, remote on-site video, and local or remote computer images; multiple cameras are used to collect local on-site video images; PC is used to send local computer images; the video conferencing host h...
