Embodiment Construction
[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0025] The present invention proposes a macroblock pair-level frame field adaptive predictive encoding / decoding method, including:
[0026] Perform the first stage of encoding / decoding:
[0027] 1) Determine whether the macroblock pair is frame coding or field coding. If it is frame coding, then encode / decode the upper and lower frame macroblocks (NS0 and NS1); if it is field coding, only the top field macroblock (VS0 ) code / decode, and store the frame field coding flag of the macroblock pair;
[0028] 2) Repeat step 1) until all frame macroblocks (NS0 and NS1) and top field macroblocks (VS0) in an image complete encoding / decoding;
[0029] In the process of the above steps 1), 2), it also includes dividing a plurality of macroblock pairs into macroblock pairs in the order of encoding, and calculating the frame field encoding signs of the ma...
