Abstract
To enable efficient use of limited bandwidth in transmitting video, a region of interest is determined in each image. Before coding, the image is spatially scaled, with magnification applied inside that a region of interest. The scaled images are then compression encoded. Meta-data identifying the location of the region of interest accompanies the transmitted video so that, after decoding, the scaling can be reversed.
