Abstract
A method and apparatus for video encoding using improved last significant coefficient coding are disclosed. According to the present invention, a location of last significant coefficient in the transform block is encoded to generate one or more syntax elements and a maximum value of the syntax elements is dependent on a block size of the transform block and a zero-out threshold, where coefficients of the transform block with coordinates greater than the zero-out threshold are set to zero. A method and apparatus for video decoding using improved last significant coefficient coding are also disclosed.
