Abstract
A method and apparatus for run length encoding video data for transform based coders. The video data is separated into blocks of pixels. The pixel values are transformed to another set of values which can be represented with less data. The transformed values are quantized by generating a quantized magnitude and sign for multiple transformed values at a time, while removing branch misprediction errors during the quanitizing process. The quantized values are run length encoded by removing branch misprediction errors during the encoding process.
