  • Generating and displaying a video stream by omitting or replacing an occluded part
    Patent number: 11924442
    Abstract: An encoder system and computer-implemented method may be provided for generating a video stream for a streaming client. The system and method may determine a part of the video which is or would be occluded during display of the video by the streaming client, for example on the basis of signaling data received from the streaming client. A video stream may be generated by, before or as part of encoding of the video, omitting the part of the video, or replacing video data in the part by replacement video data having a lower entropy than said video data. The video stream may be provided to the streaming client, for example via a network. Accordingly, a better compressible version of the video may be obtained, which when displayed by the streaming client, may still contain all or most non-occluded parts visible to a user.
