APPARATUS AND METHOD FOR PARSING BITSTREAM

摘要

PURPOSE: An apparatus for parsing a bitstream and a method thereof are provided to perform parsing corresponding to a plurality of external inputs as well as a bitstream. CONSTITUTION: A parsing unit includes an input port analyzer(301), a data receiver(302), and a parsing controller(303). The input port analyzer analyzes an input port indicating a source of data. For example, the input port analyzer analyzes a description expressed by RVC-BSDL such as an XML(eXtensible MarkUp Language) schema. The input port analyzer analyzes a rvc:from attribute that instructs the input port in the description. The rvc:from defines the input port that indicates a source of data to be received by the data receiver.
