Abstract:
1. A method for transforming a first data sequence, generated by a first moving picture coding system having an intra-frame coding mode and an inter-frame coding mode, to a second data sequence, generated by a second moving picture coding system having an intra-frame coding mode and an inter-frame coding mode, the method comprising: prereading a coding mode of a successive frame succeeding a present frame from the first data sequence; judging whether a preread coding mode of the successive frame is the intra-frame coding mode; and determining whether to code the present frame by the second moving picture coding system corresponding to a generated code amount of the second data sequence when the coding mode of the successive frame is the intra-frame coding mode, wherein data coded by the intra-frame coding mode existing in the first data sequence is preferentially transformed to the second data sequence.
