  • Publication number: 20040151394
    Abstract: Methods and apparatus for encoding and decoding image data are provided. The method includes selecting a number of sequential image frames in an image frame sequence to achieve a desired encoding performance, such as high quality or low latency, performing a three-dimensional discrete cosine transform on image data in the image frame sequence to provide a three-dimensional matrix of coefficients, and processing the coefficients to provide an encoded bit sequence for transmission. A vehicle distribution system incorporating the encoding and decoding techniques is also provided. The vehicle distribution system includes one or more encoder nodes and one or more decoder nodes coupled to a network for distributing data in a vehicle.
