Abstract
To conserve communication channel bandwidth, video information must often be compressed in low bandwidth environments. To significantly reduce bandwidth usage, a first disclosed embodiment proposes transmits a reduced color depth image initially and then later transmitting additional color depth information when the image becomes static. In this manner, a reduced color image is displayed when an image is dynamic but a full color image is displayed when the image becomes static. Note that the additional color information is transmitted only when bandwidth is has become less utilized since updated image information is no longer being transmitted since the image has become static. The additional color depth information may be stored in the same buffer or within a different buffer in the receiving system. A second embodiment delays additional color depth information and also spatially reduces the additional color depth information.
