Problems solved by technology
[0006] However, the existing network video conference live broadcast system represented by the "Sequoia Tree Live Broadcast System" can only provide videos of local areas in the venue during use. The switch makes it almost impossible for users outside the venue to watch the live broadcast through the network, especially in large-scale events, concerts and other occasions that need to mobilize the enthusiasm of the audience, the viewing experience of users outside the venue is greatly reduced
Although the panorama live broadcast system proposed by the Chinese patent CN201610166645 "Panoramic live broadcast method and device" can broadcast the panoramic information of the venue, the panoramic live broadcast in this invention cannot present the details of a certain viewpoint, and the user can only see the scene at a close distance , unable to clearly see the speaker and the content of the speech at a certain distance

The invention provides a panoramic conference live broadcasting method and system. The panoramic conference live broadcasting method comprises the steps that a panoramic image of a conference scene, a video image of a speaker and speech content of the speaker are acquired separately; a current visual center of a user is received; scene positioning is conducted in the panoramic image according to the current visual center to obtain a region scene video; and the affiliated region scene video and the video image and the speech content of the speaker are combined, and voice video information obtained after combination is obtained and sent. According to the method, visual center information of the user is acquired through VR equipment, and only the conference place scene video information according with the visual center of the user is transmitted to the user; and according to the conference live broadcasting characteristics, the speaker and the speech content video information are combined into the conference place scene video, one video is combined, the bandwidth used in transmission approaches to the bandwidth used in an existing video conference live broadcasting system, and the requirement of achieving real-time transmission under the low bandwidth condition is met.
