Methods, medium, and machines which compress, encode, enhance, transmit,
decompress and display digital video images in real time. Real time compression
is achieved by sub-sampling each frame of a video signal, encoding and filtering
the pixel values to codes, and run-length encoding the codes. Real time transmission
is achieved due to high levels of effective compression. Real time decompression
is achieved by decoding and decompressing the encoded data to display high quality
images. High levels of effective compression also reduce the storage space requirement
for recorded video.
