Patent ID: 7905604

Claim:
A wireless projection system, comprising: an image generator for generating projection image data; a compressor for compressing the projection image data; and an image transmitter for wirelessly transmitting projection image data; wherein the image generator generates a first frame of projection image data defining a viewable image for projection onto a display surface, the compressor compresses the first frame of projection image data; the image transmitter transmits the compressed first frame of projection image data, the image generator generates a subset of projection image data, wherein the subset of projection image data comprises changes from the first frame to a second frame of projection image data and wherein the subset of projection image data is less than a frame of data, the compressor compresses the subset of projection image data; the image transmitter transmits the compressed subset of projection image data, and wherein the first frame of compressed projection image data and the compressed subset of projection image data are configured to collectively construct the second frame of projection image data after decompression.
