Abstract

The invention provides a method for carrying out a video session, a video session system and set top boxes (STBs). The method comprises the following steps: a microprogrammed control unit (MCU) negotiates the capabilities of the STBs for the video session and keeps the IP address sets of the STBs for the video session and the correspondence between each IP address in the IP address sets and the video format of the corresponding STB; the STBs at the transmitting end acquire the video data from a camera and transmit the video data to the MCU; the MCU finds out the video format of the STB corresponding to the IP address of each STB at the transmitting end in the correspondence, converts the video data transmitted by the STBs at the transmitting end into the video coded formats corresponding to the found video formats of the STBs and then sends the video data to the corresponding STBs at the transmitting end; and the STBs at the transmitting end receive the video data and transmit the video data to a TV to be played after carrying out corresponding decoding on the video data. The cost of the video session can be lowered by adopting the scheme in the invention.

Description

technical field [0001] The invention relates to video media technology, in particular to a video conference method, a video conference system and a set-top box. Background technique [0002] see figure 1 , is a schematic structural diagram of a video conferencing system in the prior art, the system includes a Microprogrammed Control Unit (MCU, Microprogrammed Control Unit), and a terminal for signaling and video data interaction with the MCU through an Internet Protocol (IP, Internet Protocol) network system, the terminal system includes a camera, a video conferencing terminal and a display device. [0003] The solution for video conferencing includes: first, the MCU negotiates with each terminal system of the video conference to obtain the IP address of each terminal system participating in the video conference; then, the video conference terminal of the sending end terminal system obtains video data from the camera and transmits it to the MCU ; The MCU sends the video da...
