MULTIMEDIA ENCODING METHOD AND DEVICE BASED ON MULTIMEDIA CONTENT CHARACTERISTICS, AND A MULTIMEDIA DECODING METHOD AND DEVICE BASED ON MULTIMEDIA

摘要

Metadata includes information for effectively presenting content, and the information included in the metadata includes some information useful for encoding or decoding of multimedia data. Thus, although syntax information of the metadata is provided for an information search, an increase of encoding or decoding efficiency of data can be achieved by using strong connection between the syntax information and the data.
