Abstract
A processing unit is configured to render first pixels representative of a high-acuity region in the image and second pixels representative of a low-acuity region in the image. A shaper is configured to reorganize the first pixels based on at least one dimension of the low-acuity region. A multiplexer is configured to multiplex the reorganized first pixels and the second pixels to form a display stream. An encoder is configured to compress the display stream for transmission to a display. A decoder configured to decompress the display stream. A demultiplexer is configured to demultiplex the first pixels and the second pixels. Another processing unit is configured to blend the first pixels and the second pixels to form blended pixel values representative of the image for presentation on a screen.
