  • Circuit and method for decoding an encoded version of an image having a first resolution directly into a decoded version of the image having a second resolution
    Patent number: 6990241
    Abstract: An image processing circuit includes a processor that receives an encoded portion of a first version of an image. The processor decodes this encoded portion directly into a decoded portion of a second version of the image, the second version having a resolution that is different than the resolution of the first version. Therefore, such an image processing circuit can decode an encoded hi-res version of an image directly into a decoded lo-res version of the image. Alternatively, the image processing circuit includes a processor that modifies a motion vector associated with a portion of a first version of a first image. The processor then identifies a portion of a second image to which the modified motion vector points, the second image having a different resolution than the first version of the first image.

  • Circuit and method for formatting each of a series of encoded video images into respective regions
    Patent number: 6498816
    Abstract: A video processing circuit includes a processor that receives encoded images each having respective first and second regions and that receives a motion vector of the first region of a first one of the images. If the motion vector points to the second region of an image, the processor re-encodes at least a portion of the first region of the first image such that the first region of the first image has no motion vector that points to the second region of an image.
