First Claim
Patent Images
1. An apparatus for displaying an image corresponding to a digital image file, comprising:
- a) an image processing memory portion, the image processing memory portion including an image buffer for the computation of an image from a digital image file;
b) an integrated circuit in communication with the image processing memory portion, the circuit including integrated processing capability for the computation of the image from the digital image file;
c) a video memory portion in communication with the circuit, the video memory portion being capable of storing a plurality of computed images that are computed by the circuit; and
d) a direct memory access controller that is capable of providing efficient data transfer to or from media or interfaces that provide the digital image files to the apparatus, the image processing memory portion, the integrated circuit, and the video memory portion;
wherein the apparatus is further capable of inserting phase compensation pixels in between video frames so that an identical subcarrier phase is established in consecutive video frames.

Abstract
An apparatus for displaying digital image files on a standard display device such as a television set is provided in the form of a set-top box. The box includes an integrated circuit and memory buffer for computing an image from a file, a second memory buffer for storing computed images, and a video output for delivering the images to the display device. Preferably, the set-top box also includes an infrared receiver for remote operation. The set-top box receives the image files from standard storage media such as floppy disks.
