Abstract:
A method for coding video data is disclosed. The method comprising: receiving a rectangular array of coefficient level values having a width and a height; and for each coefficient level value included in the rectangular array, generating a corresponding transform coefficient value, wherein generating a corresponding transform coefficient value includes scaling a coefficient level value based on a quantization parameter and the width and the height of the rectangular array.
