Abstract

An apparatus for encoding a digital video signal to provide a digitally coded video signal comprises a source coder for generating a set of quantized transform coefficients corresponding to each of the coding blocks, a scanning order determination block for adaptively determining a scanning order for each video frame based on a number of quantized transform coefficients having a non-zero value, located at a same pixel position in each of the coding blocks contained in a video frame and generating scanning order information representing the scanning order for each video frame, a scanner for scanning the set of quantized transform coefficients in response to the scanning order information to thereby generate scanned quantized transform coefficients, a statistical coder for statistically coding the scanned quantized transform coefficients to thereby generate statistically coded data, and a channel coder for encoding the statistically coded data together with the scanning order information to thereby generate digitally coded video signal.
