  • QoE-based adaptive acquisition and transmission method for VR video
    Patent number: 11831883
    Abstract: The present application discloses a QoE-based adaptive acquisition and transmission method for VR video, comprising the following steps: 1, capturing, by respective cameras in a VR video acquisition system, original videos with the same bit rate level, and compressing each original video with different bit rate levels; 2, selecting, by a server, a bit rate level for each original video for transmission, and synthesizing all of the transmitted original videos into a complete VR video; 3, performing, by the server, a segmentation process on the synthesized VR video, and compressing each video block into different quality levels; and 4, selecting, by the server, a quality level and an MCS scheme for each video block according to real-time viewing angle information of users and downlink channel bandwidth information in a feedback channel, and transmitting each video block to a client.
