The encoding type of a target macroblock is determined based on the texture information thereof, and the shape information and the texture information on the target macroblock are re-formed in response to the encoding type. After the CBPY bit number of the target macroblock is determined based on the re-formed shape information, the CBPY bit number being the number of non-transparent subblock's, the re-formed texture information of the target macroblock transformed and quantized into a set of quantized transformation coefficients for each non-transparent subblock based on the CBPY bit number. The CBPY information for the target macroblock is generated, wherein the CBPY information represents whether or not the set of quantized transformation coefficients for said each non-transparent subblock contains at least one non-zero component therein, and the encoding_type and the CBPY information for the target macroblock are multiplexed into a bit stream.
