Abstract: There is provided a moving picture coding method, which is capable of effectively processing error concealment through data hiding. The moving picture coding method includes the steps of: extracting a picture header information of an inputted image at an encoder; transmitting the extracted picture header information through data hiding; and performing an error concealment using the transmitted picture header information at a decoder.

Abstract: There are provided a system for automatically generating a multimedia data description scheme (DS), and a system for searching and browsing the multimedia data based on the multimedia data description scheme (DS), the generating system providing the information to describe the multimedia data, and the browsing system allowing to search and browse the desired data by a user based on the multimedia data description scheme (DS), and including DDL parsing means, binary format decoding means, data storage means, browser interface means, and so on.
