ABSTRACT:
A method for processing an input signal is disclosed. The method generally includes the steps of (A) extracting a compressed signal and a first checksum from the input signal, (B) generating a decompressed signal by decompressing the compressed signal, (C) calculating a second checksum for the decompressed signal and (D) generating a result by comparing the first checksum to the second checksum.
