1. A method for executing video encoding operations, comprising:

  • encoding an incoming video stream into a plurality of macro blocks by using a video encoder;

    receiving a foreground-background slice map specification for the plurality of macro blocks;

    calculating a plurality of critical coordinates for each rectangle comprising the foreground background slice map specification;

    examining each of the plurality of critical coordinates to assign group membership for their respective macro blocks;

    designating the furthest macro block of the respective macro blocks from a raster origination as a last macro block of a group; and

    transmitting the data comprising the group out from the encoder once the last macro block has been processed.
