Method and apparatus for image encoding/decoding

A method of encoding an image, the method comprising:

• performing inter prediction for a current block using a motion vector and a reference picture to generate a prediction block for the current block;
• generating a residual block for the current block by subtracting the prediction block from the current block;
• and
• encoding the residual block,
• wherein the encoding of the residual block comprises
• determining a first block size and encoding information of the first block size;
• determining whether to apply the skip of the transform process on the current block based on a comparison of the first block size with a current block size;
• and
• performing or skipping a transform on the current block to encode the residual block.

A method of transmitting a bitstream which is generated by an image encoding method, the image encoding method comprising:

• performing inter prediction for a current block using a motion vector and a reference picture to generate a prediction block for the current block;
• generating a residual block for the current block by subtracting the prediction block from the current block;
• and
• encoding the residual block,
• wherein the encoding of the residual block comprises
• determining a first block size and encoding information of the first block size;
• determining whether to apply the skip of the transform process on the current block based on a comparison of the first block size with a current block size;
• and
• performing or skipping a transform on the current block to encode the residual block.
