A video signal encoder codes texture information of a video signal which includes the texture information and shape information on each of macroblocks. The encoder generates a predicted CBPY bit-number based on the shape information on a target macroblock. In the meantime, a DCT_type of the target macroblock is determined based on the texture information on the target macroblock, wherein the DCT_type represents a more effective coding technique between a progressive and an interlaced coding technique for encoding the texture information, thereby producing DCT_type information representing the DCT_type. In response to the DCT-type, the texture information on the target macroblock is transformed and CBPY information for the target macroblock is generated based on the transformed texture information. Then, the CBPY information is encoded by using the predicted CBPY bit-number and the transformed texture information is encoded to thereby produce encoded texture information. |
