The present invention provides a determination method to obtain the optimum image output quality. In at least some embodiments, the trusted third-party is utilized for both \u201cmove\u201d operations as well as local content access such as playback and the like. The method further includes inserting an advanced load instruction to one of a second plurality of registers into the modified code sequence prior to the procedure call and inserting a checking instruction associated with the advanced load instruction into the modified code sequence subsequent to the procedure call. The third circuit may be configured to generate an encoded bitstream in response to the input video signal and the selected multiplier value.
