Patent Images

1. a block mode coding method is characterized in that, may further comprise the steps:

  • Adopt the 4;


    0 sampling configuration that image block is sampled;

    Luma prediction modes according to the rules and prediction mode for chroma are carried out luma prediction and colorimetric prediction to the image block of sampling, and are obtained prediction residual;

    Prediction residual is carried out transform and quantization, and obtain residual error coefficient;

    According to the residual error coefficient that obtains, produce 5 block mode CBP sign indicating number samples;

    Occurrence number according to the value of 5 CBP sign indicating number samples sorts to all values;

    To the value flag code number after the ordering, and, to the more little sign indicating number of the value mark of the many more CBP sign indicating numbers of occurrence number number.
