A Method for Reducing the Calculation of Complexity Using Priority Information in a Multi-Object Environment

摘要

In the case of decoding multimedia data encoded in a plurality of object units, if the calculation capability that can be performed by the decoder does not reach the calculation amount required for processing the encoded data, it is necessary to decode each object And the priority information given to each object is used as a refinement calculation amount reduction method using priority information in a multi-object environment in which a decoder can process the reduced amount of computation. The conventional computational graceful degradation method has a drawback in that it does not reflect the relative importance of each object by collectively reducing the amount of computation required for decoding the entire encoded multimedia data regardless of the object characteristics. In order to overcome this disadvantage, the encoder decides the priorities of the respective objects so as to indicate the relative importance between the objects, taking into consideration that the method of reducing the amount of computational complexity is applied in the decoder, and the decoder, The amount of computation can be reduced at a different rate for each object by using the priority information of each object determined by the method.
