Problems solved by technology

[0003] The current transmission scheme is that each frame is transmitted and decoded with an image of 360 degrees in azimuth and 180 degrees in elevation. Even pixels at angles that cannot be observed are packed into video stream data for transmission and decoding, which requires a large transmission Bandwidth, and the decoding pressure of VR devices is relatively high

Abstract

The embodiment of the invention provides a VR panoramic video transmission method and device, a server and an interaction system, and the method comprises the steps: obtaining the posture parameters of VR equipment, and determining the movement trend of the VR equipment according to the posture parameters, so as to determine a to-be-displayed view field region of the VR equipment, wherein the to-be-displayed view field area is one or more of a plurality of pre-divided view field areas; acquiring video stream data corresponding to a to-be-displayed view field area; and sending the video streamdata to VR equipment according to a predetermined projection layout. According to the embodiment of the invention, the to-be-displayed view field area is firstly predicted, and then the video stream data corresponding to the view field area is sent to the VR equipment, so that the transmission of unnecessary video stream data is reduced in the whole process, the transmission bandwidth required bytransmission is reduced, and the decoding pressure of the VR equipment is greatly reduced.

Description

technical field [0001] The present disclosure relates to the field of VR, and in particular to a transmission method, device, server and interactive system for a VR panoramic video. Background technique [0002] The current 4K / 8K panoramic live broadcast value refers to the resolution of the full field of view (horizontal 360°, vertical 180°) of a frame, while VR devices only display 25%-35% of a frame due to configuration limitations. pixels, such as figure 1 and figure 2 As shown, the VR field of view is only a part of the full field of view. [0003] The current transmission scheme is that each frame is transmitted and decoded with an image of 360 degrees in azimuth and 180 degrees in elevation. Even pixels at angles that cannot be observed are packed into video stream data for transmission and decoding, which requires a large transmission Bandwidth, and the decoding pressure of VR devices is relatively high. Contents of the invention [0004] In view of this, the ...
