Abstract:
1. An apparatus for supporting plural codecs, comprising: a header analysis unit for analyzing input information of a transmitted bit stream and deciding a kind of codec being used; a switching unit, connected to the header analysis unit, configured to connect the header analysis unit to a corresponding decoder out of a plurality of decoders or to a corresponding operation block out of a plurality of operation blocks including at least one function on the basis of the input information; and a decoding unit for decoding the bit stream by means of a switched decoder or an operation block; wherein an output of the apparatus results from an output of a single decoder or a single operation block; wherein the switching unit is connected to the corresponding decoder or at least one of the plurality of operation blocks; wherein the switching unit is configured to connect the corresponding decoder to each of the at least one of the plurality of operation blocks, in response to a switch connection command; wherein a number of switches to be connected to each of the operation blocks is equal to a number of the plurality of operation blocks; and wherein a number of functions in the plurality of operation blocks connected to the switching unit is equal to or less than a number of the plural codecs.
