Abstract
A variable length coder is disclosed. The variable length coder comprises a size determining unit and a first residual coder. The size determining unit determines a maximum size based on sizes of quantized residuals in a current group and determines whether to enable the first residual coder according to the maximum size. When the maximum size is equal to 1, the first residual coder is enabled to encode the quantized residuals as one symbol to generate a first encoded suffix according to a variable length coding scheme.
