Claim 9:
10. A computer program product for controlling the transfer of image data across a digital picture interface, said computer program product comprising a non-transitory storage medium having thereon computer-readable code means which when run in a processor controlling an image display system will cause the system to perform the transfer according to the method according to the following steps:
dividing incoming image data into framebuffers, each framebuffer comprising a number of pixels to be displayed as an image on a display unit in the image display system,
for each framebuffer:
dividing the framebuffer into a number of vertical stripes, each stripe comprising one or more scanlines,
dividing each vertical stripe into a plurality of blocks, each of the plurality of blocks comprising pixel data to be displayed in an area of the image, and storing first pixel data in a first block with a first resolution and second pixel data in second blocks having second resolutions lower than the first resolution and holding pixel data to be displayed outside of opposite sides of the first pixel data, wherein the second blocks are positioned on opposite sides of the first block in the frame buffer,
transmitting the framebuffer over the digital display interface to a decoder unit, and
unpacking the framebuffer in a decoder unit, upscaling the pixel data in the second block to compensate for the lower second resolution and optionally upscaling the pixel data in the first block.
