Claim One:
1. An apparatus of encoding a video using an inter prediction, the apparatus comprising: a motion vector encoder configured to determine a current motion vector of a current block to be encoded; a motion compensator configured to generate a predicted block by predicting the current block using the current motion vector; a subtractor configured to generate a residual block by subtracting the predicted block from the current block; and a residual data encoder configured to identify whether transform from a spatial domain into a frequency domain and quantization are applied to residual signals in the residual block, and encode, into a bitstream, the residual signals in the residual block by selecting, based on the identification of whether the transform and the quantization are applied, one of the following processes: transforming and then quantizing the residual signals to thereby encode the transformed and quantized residual signals, skipping the transform of the residual signals and quantizing the residual signals to thereby encode the quantized residual signals which are not transformed, and skipping both the transform and the quantization to thereby encode the residual signals which are neither transformed nor quantized.
