[Prior Art] H.323 is part of the International Telecommunications Union (ITU) multimedia communication series standard χ·32χ, which makes video conferencing possible on existing communication networks. Among them, Η.320 is in narrowband integrated services. Service Network _ (N-ISDN) standard for multimedia communication, Η·321 is the standard for multimedia communication on Broadband Integrated Service Network (B-ISDN), Η.322 is for LAN with service quality assurance (LAN) The standard for multimedia communication, H.324 is the standard for multimedia communication over the public switched telephone network (GSTN) and wireless networks, and H.323 is the existing packet network (PBN) * for multimedia communication such as IP networks standard. H.323 defines four main components for network-based multimedia communication systems: Terminal, Gageway, Gagekeeper, and Multipoint Control Unit (MCU). The terminal is a node device capable of providing instant and two-way communication in a packet network, and is also an end user device capable of communicating with a gateway and a multipoint control unit. All terminals must support voice communication, but video and data communication are optional. H.323 specifies the operating modes required for different audio, video or data terminals to work together. It will be the primary standard for next-generation Internet telephony, audio conferencing endpoints and video conferencing technology. When performing multimedia communication, at the transmitting end, the video and audio signals obtained from the input device are compressed by the encoder and then packaged according to a certain format. In 200828945, the unpacking is sent out through the network. At the receiving end, the data packet from the network is first decoded and the audio compressed data is decoded and sent to the output device. The user's data and control data are also processed accordingly. The frequency end, such as a mobile phone, usually has a built-in camera and a video communication device on the video, and does not know what it is: = state, may send the gold product to the other party, + ^ own video shows an intersexuality The recognition is not ideal. In order to solve the above problems, the method is as follows: the screen displays the video of the other party's video and the local video 盥 = show: = Shen: public (10) TM data and from far::: and method. It sets the video of the video set by the camera: different gamma, so that the foreground and the back of the mobile phone can be distinguished in the order of the mobile phone. It can be applied well in the case of using a mobile phone, but in the case of frequent calls, it is not only necessary to know the video sent by the remote terminal of the machine. It is necessary to understand other participation in video communication [invention content] In view of this, it is necessary to connect the _ surface method and a special application; ^ display the complex video communication terminal on the ^, which can be used for multi-party video The video transmitted by the mobile communication terminal of the call. ° 'A simultaneous display of multiple remote shifts - a method for displaying multi-party video calls, the package will display the video written 〖 乂 直 直 直 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成 分成The terminal corresponds to an area/sub-window, and the video vertical frequency signal sent by each remote mobile communication terminal is obtained from the decoder, and the following judgment is made.
