Claim Text:
1. A method of transcoding an input signal to a plurality of output signals by a transcoding system, the method comprising: receiving an input signal; scaling a signal associated with the input signal by a first scaling factor to generate a first scaled signal; scaling the signal associated with the input signal by a second scaling factor to generate a second scaled signal; computing a first partial value based on at least input of the first scaled signal, the first partial value being determined so as to provide a common computing value between an output to subsequent encode operations and to one or more lower tier motion estimators; determining a first tier motion estimate output based on at least the first partial value, wherein the first partial value represents one or more encoding functions associated with the first scaled signal; and determining a second tier motion estimate input based on at least the first partial value, where each successively lower tier among a plurality of tiers of motion estimators is operable to use a respective tier motion estimate input received from a higher tier motion estimator along with a respective tier scaled input to calculate a respective tier partial value to be used to generate a respective tier motion estimate output and a successively lower tier motion estimate input for providing to at least a next lower tier motion estimator.
