Abstract: Motion estimation in video encoding switches among motion estimation methods for successive predicted pictures depending upon statistics of prior pictures. Locally averaged motion vectors, fraction of intra-coded macroblocks, average quantization parameter, and so forth provide tests for applicability of particular motion estimation methods, such as ones which perform better for large motion or perform better for small motion with complex texture.

Abstract: A method is provided for generating an image having a plurality of bands. A page description representative of elements of the image is received from an external source. A display list buffer is then built that has a plurality of display list elements (DLE) derived from the page description, each display list element being representative of a corresponding graphic item. A banded display list is then built that is representative of the plurality of bands of the image. For each band of the plurality of bands, a set of templates is stored in the banded dismay list in which each template points to a DLE in the display list buffer for each corresponding graphic item that is spawned within the band. Each band is then rendered by using the set of templates stored for that band to access a corresponding set of DLEs from the display list buffer. In one embodiment, a printer includes a microprocessor with on-chip memory.
