Abstract: A USB phone supporting multi-device conference application includes: a touch display module, an audio processing module, a digital enhanced cordless telecommunications (DECT) module, a Bluetooth module, a USB interface, and an MCU controller. The Bluetooth module is configured to establish a Bluetooth communication connection with an external Bluetooth terminal; the USB interface is configured to establish a USB communication connection with an external intelligent terminal; the DECT module is configured to establish a communication connection with an external wireless headphone; the touch display module is configured to display data, and recognize and obtain a touch operation instruction; the audio processing module is configured to perform audio processing on received audio data; the MCU controller is configured to process received data, further provided with a first mixer and connected to the touch display module, the audio processing module, the DECT module, the Bluetooth module, and the USB interface.

Abstract: Disclosed are a communication device having a base station function of a Digital Enhanced Cordless Telecommunications (DECT) cellular system, and a communication system. The communication device includes an IP phone and a DECT adapter. The IP phone is connected to the DECT adapter, to form a base station; and the DECT adapter is configured to wirelessly communicate with at least one cordless handset via DECT, so as to register information of the at least one cordless handset with the IP phone. The present application enables the IP phone to be externally connected to the DECT adapter to support a DECT mode, so that the IP phone possesses a base station function of a DECT cellular system. It is not required to deploy multiple different systems. Such an IP phone and other base stations can form a Multi-Cell DECT system, expanding the coverage of a DECT signal.

Abstract: The present disclosure relates to the field of communications technologies, and specifically, to a video conference terminal and a video conference system. The video conference terminal is provided with a content receiving module (101), an audio and video processing module (102), and a display module (103). To be specific, the video conference terminal (100) has a video conference function, so that the video conference terminal can serve as both an audio conference terminal and a video conference terminal, thereby enriching functions of the video conference terminal. Compared with a conventional conference terminal, the video conference terminal provided in embodiments of the present disclosure has easy deployment, low costs and high utilization as it can serve as a video conference terminal.

Abstract: The present disclosure discloses an information interaction method, an information interaction system, and an application thereof, and belongs to the field of electronic whiteboards. In view of the problems in the prior art that an electronic whiteboard in a conference system has a large amount of data to be transmitted, requires a large interaction bandwidth, and has high network requirements, the present disclosure provides an information interaction method: When an image is annotated on the local device, the host serializes the annotation on the local device. The remote device combines the serialized data and corresponding coordinates and pressure sensing values, to calculate and draw an image for display from the data by using a GPU. The interaction method is applied to the electronic whiteboard in the conference system, thereby realizing multi-party real-time interactive whiteboard collaboration, which is supported in both local conferences and teleconferences.
