<p>A method for controlling a video stream bit rate while encoding a macroblock of a video stream having pictures comprising the step of using a quantiser_scale_code of the general form: quantiser_scale_code = ROUND (A + B (D+log C (MIN{VAR[luma_0],...,VAR[luma_n]}))) €ƒ€ƒ€ƒwith A being an adjustable gear shift parameter; and B being an adjustable gas pedal parameter; and [luma_n] being a nth luminance block of said macroblock; and D being a constant parameter depending on the encoded picture type.</p> |
