Patent ID: 8050495

Claim:
A method, comprising: retrieving a rich media file from a network, the rich media file including compressed information and a viewer configured to display the information after decompression on a computer, the compressed information and the viewer contained in a single file; and de-compressing the information, wherein de-compressing the information comprises: decoding a probability value for a compressed color for a pixel; determining whether the probability value represents the same color as a left neighbor color for a left neighbor of the pixel or an upper neighbor color for an upper neighbor of the pixel using a probability model, the probability model being one of a plurality of probability models in a probability set that include a probability value that the compressed color for the pixel represents the same color as a left neighbor color for a left neighbor of the pixel or an upper neighbor color for an upper neighbor of the pixel; decoding an uncompressed color for the pixel; and updating the probability model.
