A data transmission method, where a host acquires parameter information of a wireless communication channel between a wireless microphone array and the host, that is, a signal-to-noise ratio or bandwidth. The host reduces sampling frequency of the wireless microphone array or decreases a quantity of data transmission paths between the wireless microphone array and the host when the acquired parameter information satisfies a first preset condition such that bandwidth occupied when the wireless microphone array transmits data is reduced.

Data transmission method and system, and related device

A device for quick splicing of a display screen is provided. The device includes a left assembly and a right assembly. The left assembly includes a rotation fixing seat, a rotation angle seat, a rotation locking mechanism, and a step angle-adjusting and clamping mechanism. The rotation angle seat can lock with the right assembly, and is rotatably connected to the rotation fixing seat. The rotation locking mechanism is disposed between the rotation fixing seat and the rotation angle seat. When the rotation locking mechanism is unlocked, the rotation angle seat can rotate relative to the rotation fixing seat; and when the rotation locking mechanism is locked, the rotation angle seat is fixedly connected to the rotation fixing seat. The step angle-adjusting and clamping mechanism is disposed between the rotation angle seat and the rotation fixing seat.

A method and an apparatus for calling a terminal to join a conference, related to the field of communications technologies, resolving a problem that a process in which a calling terminal calls a called terminal to join the conference or a called terminal requests joining the conference is complicated. The method includes the following steps: receiving first call request information, where the first call request information carries identification information of the called terminal; and calling the called terminal according to the identification information of the called terminal, so that the called terminal receives a message which is published by another terminal in a current conference and that the called terminal publishes a message to another terminal in the current conference. The method may be applied to calling a terminal to join a conference.

A system for providing multi-language conference is provided. The system includes conference terminals and a multipoint control unit. The conference terminals are adapted to process a speech of a conference site, transmitting the processed speech to the multipoint control unit, process an audio data received from the multipoint control unit and output it. At least one of the conference terminals is an interpreting terminal adapted to interpret the speech of the conference according to the audio data transmitted from the multipoint control unit, process the interpreted audio data and output the processed audio data. The multipoint control unit is adapted to perform a sound mixing process of the audio data from the conference terminals in different sound channels according to language types, and then sends mixed audio data after the sound mixing process to the conference terminals.
