Abstract

See full text

The development of a region of interest (ROI) video frame that includes only ROIs of interest and not other elements and providing the ROI video frames in a single video stream simplifies the development of gallery view continuous presence displays. ROI position and size information metadata can be provided or subpicture concepts of the particular codec can be used to separate the ROIs in the ROI video frame. Metadata can provide perspective/distortion correction values, speaker status and any other information desired about the participant or other ROI, such as name. Only a single encoder and a single decoder is needed, simplifying both transmitting and receiving endpoints. Only a single video stream is needed, reducing bandwidth requirements. As each participant can be individually isolated, the participants can be provided in similar sizes and laid out as desired in a continuous presence display that is pleasing to view.
