Method and system for implementing video conference and broadband mobile hotspot device

A system for implementing a video conference, comprising:

• a broadband mobile hotspot device and a multipoint conference server, wherein:
• the broadband mobile hotspot device is a wireless comprehensive application equipment which integrates 3G broadband wireless communication technology and Wi-Fi broadband wireless access technology, and terminal devices accessing to the broadband mobile hotspot device through a Wi-Fi local area network, and the broadband mobile hotspot device communicating with the multipoint conference server through 3G wireless communication technology;
• the broadband mobile hotspot device is configured to:
• send a local panorama video image and voice signals to the multipoint conference server;
• after receiving panorama video images and the voice signals sent by other broadband mobile hotspot devices from the multipoint conference server, mosaic the local panorama video image and the received panorama video images as a conference panorama video image, and after synchronizing the conference panorama video image with the received voice signals, send the synchronized conference panorama video image and voice signals to the terminal devices participating in the video conference under the broadband mobile hotspot device;
• wherein the local panorama video image is generated by performing image mosaicking processing on video image signals sent by the terminal devices participating in the video conference under the broadband mobile hotspot device to which each terminal device belongs;
• the multipoint conference server is configured to:
• send the local panorama video image and the voice signals sent by the broadband mobile hotspot device to the other broadband mobile hotspot devices participating in the video conference except a sender;
• wherein the multipoint conference server is configured to authenticate the terminal devices, and return permission information or rejection information to the terminal devices;
• and
• the terminal devices are configured to start to collect the video image signals and the voice signals of the user after receiving the permission information.

A broadband mobile hotspot device, comprising:

• a wireless access point and a video image mosaicking processor, wherein:
• the broadband mobile hotspot device is a wireless comprehensive application equipment which integrates 3G broadband wireless communication technology and Wi-Fi broadband wireless access technology, terminal devices accessing to the broadband mobile hotspot device through a Wi-Fi local area network, and the broadband mobile hotspot device communicating with a multipoint conference server through 3G wireless communication technology;
• the wireless access point is configured to:
• send a local panorama video image and voice signals to the multipoint conference server;
• receive panorama video images and voice signals sent by other broadband mobile hotspot devices participating in the video conference from the multipoint conference server;
• and send a conference panorama video image and voice signals synchronized by the video image mosaicking processor to the terminal devices participating in the video conference under the broadband mobile hotspot device;
• wherein the local panorama video image is generated by performing image mosaicking processing on video image signals sent by the terminal devices participating in the video conference under the broadband mobile hotspot device to which the terminal devices belong;
• the video image mosaicking processor is configured to:
• mosaic the local panorama video image and the panorama video images received by the wireless access point as the conference panorama video image, and synchronize the conference panorama video image with the received voice signals;
• wherein the multipoint conference server is configured to authenticate the terminal devices, and return permission information or rejection information to the terminal devices;
• and
• the terminal devices starting to collect the video image signals and the voice signals of the user after receiving the permission information.
