Abstract:
1. A transmission system comprising a processor configured to: receive a plurality of frames; analyze the plurality of frames; determine a current bandwidth available for transmission; determine, based on the current bandwidth, at least one of a pixel movement threshold or a pixel size threshold, the pixel movement threshold being a distance between a position in a first frame of a particular image object and a position in a second frame of the particular image object wherein the distance corresponds to a first number of pixels and the pixel size threshold being a difference between a dimension in the first frame of the particular image object and a dimension in the second frame of the particular image object wherein the difference corresponds to a second number of pixels; identify foreground-object portions that are distinct from a background portion; transmit, for each of the plurality of frames, foreground-object information for an identified foreground-object portion based on the identified foreground-object portion satisfying the at least one of the pixel movement threshold or the pixel size threshold; and selectively transmit background information for less than all of the plurality of frames, wherein the background information is transmitted at a periodic rate based on the current bandwidth.
