A method that provides for dynamic loop transfer for a method having a first set of instructions being executed by an interpreter is provided. An execution stack includes slots for storing a value of each local variable known to each subroutine while the subroutine is active. The method comprises suspending execution at a point for which a current execution state can be captured from the execution stack; assigning the value in each slot of the execution stack to a corresponding slot of an array of values; scanning the first set of instructions to identify a data type for local variable that is not known in the current execution state and shares a slot in the execution stack with a local variable that is known; and generating a second set of instructions for the method coded to be initially executed to declare each local variable that is known in the current execution state and each local variable for which a data type was identified, assign each declared variable with the value assigned to the slot in the array that corresponds to the slot of the execution stack in which the value of the variable is stored during execution of the first set of instructions, and branch to a target point in the second set of instructions that corresponds to the point at which execution was suspended.

A method codes pictures in a bitstream, wherein the bitstream includes coded pictures to obtain data for associated TUs and data for generating a transform tree, and a partitioning of coding units (CUs) into Prediction Units (PUs), and data for obtaining prediction modes or directions associated with each PU. One or more mapping tables are defined, wherein each row of each table has an associated index and a first set of transform types to be used for applying an inverse transformation to the data in TU. The first set of transform types is selected according to an index, and then a second set of transform types is applied as the inverse transformation to the data, wherein the second set of transform types is determined according to the first set of transform types and a transform-toggle flag (ttf) to obtain a reconstructed prediction residual.

A rate control method with region of interesting support, which coding macroblocks in a current picture with different priority. The rate control method calculates a weighted macroblock activity according to the priority and a macroblock activity and a picture activity for the current picture according to the weighted macroblock activity. Then, the method allocates a bit budget for each macroblock according to the priority and calculates an estimated complexity for the current picture according to a complexity of a previously coded picture, an activity of the previously coded picture and the weighted macroblock activity. The method also calculates an estimated quantizer scale according to the estimated complexity and the bit budget, an initial virtual buffer occupancy according to an reaction factor and the estimated quantizer scale and a macroblock quantizer scale according to a virtual buffer occupancy of a previously coded macroblock, the priority and the reaction factor. The method codes each macroblock according to the macroblock quantizer scale and updates a virtual buffer occupancy of the current coded macroblock according to a used bit of the coded macroblock, the virtual buffer occupancy of the previously coded macroblock and the bit budget of current coded macroblock.
