ABSTRACT:
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 coded block pattern type (CBPY) bit-number based on the shape information on a target macroblock. In the meantime, a DCT.sub.-- type of the target macroblock is determined based on the texture information on the target macroblock, wherein the DCT.sub.-- type represents a more effective coding technique between a progressive and an interlaced coding techniques for encoding the texture information, thereby producing DCT.sub.-- type information representing the DCT.sub.-- type. In response to the DCT.sub.-- 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.
