Abstract
This disclosure describes unique video encoding and decoding processes compliant to one or more specific coding standards, such as the H.264/AVC standard, without sacrificing coding efficiency. A higher resolution input image is divided into a corresponding set of lower resolution sub-sampled images. The first image of each set is coded as an independent I picture, or coded with respect to the first image of one or more other sets as a P or B picture. Each subsequent image of a set, other than the first image in each set, is encoded with respect to the first image of the same set or an image of another set as a regular P or B picture. A decoding process may employ a decoder conforming to the specific coding standard to decode the encoded data, by rearranging the decoded lower resolution sub-sampled images of each set into corresponding higher resolution output images.
