Abstract
A method and apparatus for storing and displaying video image data in a video graphics system is accomplished by receiving a video data stream, where the video data stream includes compressed video image data. The video image stream is parsed to separate the compressed video image data from other data within the data stream. The compressed video image data is decompressed to produce video image data that includes a luminosity plane, a first color plane, and a second color plane. Members of the first and second color planes are compacted together to form color pairs where a plurality of the color pairs form a color line. Each of the color lines is interleaved with at least one luminosity line to produce an interleaved plane. The interleaved plane is stored in memory. Portions of the interleaved video image data are retrieved from the interleaved plane. The portions are structured such that video image data that are located near each other within the memory are fetched together. A video output is generated based on the retrieved groups of image data where the luminosity and color values within each of the fetched groups of image data are utilized together to produce the video output.
