SINGLE-STREAM FOVEAL DISPLAY TRANSPORT

Systems, apparatuses, and methods for implementing a single-stream foveal display transport are disclosed. A system includes a transmitter sending an image over a display transport as a sequence of equi-sized rectangles to a receiver coupled to a display. The receiver then scales up the rectangles with different scale factors to cover display areas of different sizes. The pixel density within a rectangular region is uniform and scaling factors can take on integer or non-integer values. The rectilinear grid arrangement of the image results in simplified scaling operations for the display. In another scenario, the image is transmitted as a set of horizontal bands of equal size. Within each band, the same horizontal amount of transmitted pixels are redistributed across multiple rectangular regions of varied scales. The display stream includes embedded information and the horizontal and/or vertical distribution and scaling of rectangular regions, which can be adjusted for each transmitted image.
