Abstract
An apparatus encodes a video signal composed of texture information and shape information by selectively using a progressive and an interlaced coding technique. The shape information is divided into a multiplicity of BABs of M×N pixels having one of a first and a second binary values and the texture information has a plurality of macroblocks of the same number of pixels as a BAB. Specifically, the apparatus determines a motion vector of a target BAB of the shape information based on a corresponding motion vector predictor selected among candidate motion vectors including frame-based and field-based motion vectors for BABs which surround the target BAB and have been previously encoded and frame-based and field-based motion vectors for macroblocks which surround the macroblock corresponding to the target BAB and also have been previously encoded according to predetermined priority, and encodes the motion vector of the target BAB.
