Abstract:
1. A data processing system comprising: a designation input unit configured to designate at least a desired method related to an application layer and a method related to hardware control layer, respectively; a signal processor configured to selectively carry out methods related to the application layer and including a storage unit to store a plurality of methods; a hardware controller configured to selectively carry out methods related to the hardware control layer, the hardware controller controlling an internal circuit in the data processing system by carrying out the methods; a controller configured to control the signal processor or hardware controller by reading from the storage unit one method in response to the designation from the designation input unit to carry out the designated method; a transmitting unit configured to send data; a receiver unit adapted to receive transmitted data; and an output unit configured to output received content data; the signal processor being controlled by the controller to process supplied content data by carrying out a method selected on the basis of the designation supplied from the designation input unit, and output the processed content data to the transmitter and said, signal processor holding a method which is a compression algorithm including the steps of: extracting an interesting image block corresponding to an interesting pixel from image data supplied as content data; classifying the interesting pixel based on the values of pixels included in the interesting image block; outputting an estimated value of the interesting pixel, obtained by a linear primary combination of a plurality of coefficients pre-computed for each class and stored and the value of each pixel included in the estimation image block corresponding to the interesting pixel; and encoding a value resulted from subtraction of the estimated value from the value of the interesting pixel.
