ABSTRACT:
A decoder for decoding a target image from a signal. The signal includes S facsimile encoded sub-image messages transmitted in a predetermined order. The decoder also stores a runlength code book. The decoder includes a facsimile decoder (910), a sub-image memory (920), a target image generator (940), and a target image memory (930). The facsimile decoder (910) is for generating S sub-images from the S facsimile encoded sub-image messages, using the runlength code book. Each of the S sub-images includes sub-image lines includes pixels. The sub-image memory (920) is for storing the S sub-images. The target image generator (940) is for re-assembling the target image from the S sub-images. The target image memory (930) is for storing the target image.
