Apparatus for processing a data stream having a hierarchical layer structure and including encoded data sets and raw data sets and method thereof

摘要

An apparatus for processing a data stream having a hierarchical layer structure and including encoded data sets and raw data sets is provided. The apparatus includes a first processing circuit for generating an enable signal corresponding to a predetermined layer of the hierarchical layer structure when detecting that a data set of the data stream corresponds to the predetermined layer, and a second processing circuit coupled to the first processing circuit for detecting whether an identifier of the data set corresponds to one predetermined raw data set identifier when receiving the enable signal from the first processing circuit.
