Abstract: Provided are a video communication method and device. The method includes: a cloud platform stored conference related information of a video conference terminal is received from the cloud platform; and according to the conference related information, a video conference is initiated. The disclosure improves the efficiency of holding the video conference.

Abstract: Disclosed is a secondary-stream data accessing method for a videoconference terminal. The method includes: playing secondary-stream data using a playing tool installed in the videoconference terminal, and collecting video data or audio video data of the secondary-stream data; and coding the collected video data or the collected audio video data and sending the coded video data or the coded audio video data to a target videoconference terminal. Further disclosed are a videoconference terminal and a computer storage medium.

Abstract: A terminal, multipoint control unit, system and method for implementing high definition multiple pictures are provided by the present invention. The method comprises the following steps of: a Multipoint Control Unit (MCU) calculating a high definition video code stream format according to video conference control information, and sending a capability set containing the high definition video code stream format to a selected terminal; based on the high definition video code stream format in the capability set, the selected terminal encoding a high definition video image and sending the encoded high definition video code stream to the MCU; according to the video conference control information, the MCU synthesizing the received high definition video code stream image into multiple pictures, and obtaining the high definition multi-picture video code stream image and sending it to the terminals attending the conference.
