1. an adaptive video coding/decoding method, described adaptive video coding/decoding method includes:

  • The bit stream information of incoming bit stream based on complicacy self-adaptive Video Decoder, performs decoding complex degree management, to decide whether to reduce the decoding complex degree of multiple elements in described complicacy self-adaptive Video Decoder;

    AndThe decoding complex degree of the plurality of element in the selectivity described complicacy self-adaptive Video Decoder of reduction;

    Wherein, the plurality of element includes;

    quickly variable length decoding and inverse quantization module, for described incoming bit stream is performed quick variable length decoding and inverse quantization, to produce multiple inverse quantization result;

    Motion compensating module, for performing motion compensation according to described incoming bit stream and producing corresponding multiple prediction output result, wherein said motion compensating module comprises time prediction unit and spatial prediction unit, and described time prediction unit exports a part for result for running time prediction to produce the plurality of prediction;

    And described spatial prediction unit is for performing spatial prediction to produce a part for the plurality of prediction output result;

    Computing unit, is used for adding up to multiple inverse transformation result and the plurality of prediction output result to export result to produce multiple compensation;

    Reconstruction frames output unit, for producing multiple reconstruction frames according to the plurality of output result that compensates, wherein, described spatial prediction unit performs spatial prediction according to the current reconstructed frame of the plurality of reconstruction frames;

    And frame memory element, the at least some of of the plurality of reconstruction frames is stored for interim, wherein, described time prediction unit is according to described at least some of running time prediction of the plurality of reconstruction frames, and described time prediction unit operates according to the resolution of the plurality of reconstruction frames, to reduce the complexity of running time prediction.
