Claim 2:
3. A method to decode an image comprising:
determining a scanning mode for transform coefficients based on intra information, wherein the intra information is determined based on intra prediction mode information in a bitstream and the intra prediction mode information is for an intra prediction to obtain predicted pixel values;
performing entropy decoding of encoded video information to obtain the transform coefficients;
scanning the transform coefficients based on the scanning mode; and
performing the intra prediction using the intra prediction mode information to obtain predicted pixel values,
wherein a direction of the scanning mode is determined to be horizontal in a case that a direction of the intra information is vertical, and
wherein the direction of the scanning mode is determined to be vertical in a case that the direction of the intra information is horizontal.
