Abstract
Methods of encoding an image stream. In one embodiment, the method comprises analyzing, for each block in a plurality of image blocks, changes from the same block in previous image frames; classifying each block as a non-video block if it has changed from a corresponding block in an immediately previous frame; re-classifying each non-video block as a video block if it meets video block requirements; encoding each non-video block having a first image type to a lossless quality level; encoding each non-video block having a second image type to a first lossy quality level; and encoding each video block to a second lossy quality level, wherein each of the lossless quality level, the first and the second lossy quality levels define a measurable image quality level of a decoded output of a corresponding block at a client computer, wherein the image frame comprises separate video insert, text and picture portions.
