description The invention provides a virtual reality view field distribution method, system, device and equipment and a medium, and relates to the technical field of video transmission, and the method comprises the steps: predicting a historical virtual reality video, obtaining a popularity view angle region at the current moment, segmenting the virtual reality video at the current moment, obtaining a plurality of video fragments, and transmitting the video fragments to a server; and determining an intersection area between the popularity view angle area at the current moment and the view angle request of the at least one user, distributing the video fragments at the current moment in the intersection area in a multicast form through a multicast group, and distributing the video fragments at the current moment in a non-intersection area of the at least one user in a unicast form. According to the method, multicast resources can be used to the maximum extent through the multicast technology, bandwidth is saved, and time d
