Patent ID: 7376132

Claim:
A method for determining perceptual quality of a received encoded framed signal, comprising the following steps: copying said received encoded framed signal to obtain a copied encoded framed signal; determining a framing technique used for framing said received encoded framed signal; determining an encoding technique used for encoding said received encoded framed signal; encoding a known media signal with said encoding technique used for encoding said received encoded framed signal to produce a known encoded signal; framing said known encoded signal with said framing technique used for framing said received encoded framed signal to produce a known encoded framed signal; replacing content of said copied encoded framed signal with content of said known encoded framed signal to produce a pseudo-encoded framed signal; determining a perceptual quality of said pseudo-encoded framed signal; and using said perceptual quality of said pseudo-encoded framed signal to generate a perceptual quality of said received encoded framed signal.
