<p>The present invention provides an apparatus and method for, in at least one of: encoding and decoding, scanning transform coefficients in an image/video encode/decoder. In encoding the steps include: segregating a predetermined number of quantized transform coefficients into a plurality of coefficients zones and storing the coefficient zones in a memory unit (102); examining each coefficient to determine which zone/zones has/have at least one non-zero coefficient (104); scanning each coefficient of the zones having at least one non-zero coefficient in a predetermined scanning order (106); encoding which coefficient zone contains at least one non-zero coefficient to provide first entropy-encoded information bits (108); determining whether at least one coefficient zone is to be encoded (110); encoding the non-zero coefficients to provide second entropy encoded information bits (112). Decoding is accomplished in mirror fashion.</p> |
