ABSTRACT:
The present invention is an improved transmission system for JPEG images. The present invention may include a separator for separating the JPEG image into Type-I and Type-II information and a transmitter for transmitting the Type-I and Type-II information over a wire or wireless communication medium to a receiver with unequal error protection, wherein the more error sensitive Type-I information is provided with more powerful error protection than the less sensitive Type-II information which makes up the bulk of the JPEG image. The present invention may further include a combiner for combining the Type-I and Type-II information received by the receiver in a JPEG format suitable for the data sink.
