Abstract
Systems for controlling a presentation of data images in a video stream, comprising: at least one processor programmed to: transmit a video bit stream representing a plurality of images to a plurality of receivers using common transmission parameters; determine that a transmission link to one of the plurality of receivers is degraded; select one of the plurality of images for transmission to the one of the plurality of receivers; select degraded-link transmission parameters for transmission of the one of the plurality of images on the degraded transmission link, wherein the degraded-link transmission parameters are different from the common transmission parameters; transmit the one of the plurality of images to the one of the plurality of receivers using the degraded-link transmission parameters; and continue to transmit the video bit stream to at least one other of the plurality of receivers using the common transmission parameters.
